Forward-Looking Statements

This report and other presentations made by Hawaiian Electric Industries, Inc. (HEI) and Hawaiian Electric Company, Inc. (HECO) and their subsidiaries contain “forward-looking statements,” which include statements that are predictive in nature, depend upon or refer to future events or conditions, and usually include words such as “expects,” “anticipates,” “intends,” “plans,” “believes,” “predicts,” “estimates” or similar expressions. In addition, any statements concerning future financial performance, ongoing business strategies or prospects or possible future actions are also forward-looking statements. Forward-looking statements are based on current expectations and projections about future events and are subject to risks, uncertainties and the accuracy of assumptions concerning HEI and its subsidiaries (collectively, the Company), the performance of the industries in which they do business and economic and market factors, among other things. These forward-looking statements are not guarantees of future performance.

Risks, uncertainties and other important factors that could cause actual results to differ materially from those in forward-looking statements and from historical results include, but are not limited to, the following:

·            international, national and local economic conditions, including the state of the Hawaii tourism and construction industries, the strength or weakness of the Hawaii and continental U.S. real estate markets (including the fair value and/or the actual performance of collateral underlying loans held by American Savings Bank, F.S.B. (ASB), which could result in higher loan loss provisions and write-offs), decisions concerning the extent of the presence of the federal government and military in Hawaii, and the implications and potential impacts of current capital and credit market conditions and federal and state responses to those conditions;

·            weather and natural disasters, such as hurricanes, earthquakes, tsunamis, lightning strikes and the potential effects of global warming (such as more severe storms and rising sea levels);

·            global developments, including terrorist acts, the war on terrorism, continuing U.S. presence in Afghanistan, potential conflict or crisis with North Korea or in the Middle East;

·            the timing and extent of changes in interest rates and the shape of the yield curve;

·            the ability of the Company to access credit markets to obtain commercial paper and other short-term and long-term debt financing (including lines of credit) and to access capital markets to issue HEI common stock under volatile and challenging market conditions, and the cost of such financings, if available;

·            the risks inherent in changes in the value of pension and other retirement plan assets and securities available for sale;

·            changes in laws, regulations, market conditions and other factors that result in changes in assumptions used to calculate retirement benefits costs and funding requirements;

·            the impact of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (Dodd-Frank Act) and of the rules and regulations that the Dodd-Frank Act requires to be promulgated over the next several months;

·            increasing competition in the electric utility and banking industries (e.g., increased self-generation of electricity may have an adverse impact on HECO’s revenues and increased price competition for deposits, or an outflow of deposits to alternative investments, may have an adverse impact on ASB’s cost of funds);

·            the implementation of the Energy Agreement with the State of Hawaii and Consumer Advocate (Energy Agreement) setting forth the goals and objectives of a Hawaii Clean Energy Initiative (HCEI), revenue decoupling and the fulfillment by the utilities of their commitments under the Energy Agreement (given the Public Utilities Commission of the State of Hawaii (PUC) approvals needed; the PUC’s potential delay in considering HCEI-related costs; reliance by the Company on outside parties like the state, independent power producers (IPPs) and developers; potential changes in political support for the HCEI; and uncertainties surrounding wind power, the proposed undersea cable (to bring power to Oahu from Lanai and/or Molokai), biofuels, environmental assessments and the impacts of implementation of the HCEI on future costs of electricity);

·            capacity and supply constraints or difficulties, especially if generating units (utility-owned or IPP-owned) fail or measures such as demand-side management (DSM), distributed generation (DG), combined heat and power (CHP) or other firm capacity supply-side resources fall short of achieving their forecasted benefits or are otherwise insufficient to reduce or meet peak demand;

·            the risk to generation reliability when generation peak reserve margins on Oahu are strained;

·            fuel oil price changes, performance by suppliers of their fuel oil delivery obligations and the continued availability to the electric utilities of their energy cost adjustment clauses (ECACs);

·            the impact of fuel price volatility on customer satisfaction and political and regulatory support for the utilities;

·            the ability of the electric utilities to negotiate, periodically, favorable fuel supply and collective bargaining agreements;

·            new technological developments that could affect the operations and prospects of HEI and its subsidiaries (including HECO and its subsidiaries and ASB) or their competitors;

·            federal, state, county and international governmental and regulatory actions, such as changes in laws, rules and regulations applicable to HEI, HECO, ASB and their subsidiaries (including changes in taxation, increases in capital requirements, regulatory changes resulting from the HCEI, environmental laws and regulations, the regulation of greenhouse gas emissions (GHG), healthcare reform, governmental fees and assessments (such as Federal Deposit Insurance Corporation assessments), and potential carbon “cap and trade” legislation that may fundamentally alter costs to produce electricity and accelerate the move to renewable generation);

·            decisions by the PUC in rate cases and other proceedings (including the risks of delays in the timing of decisions, adverse changes in final decisions from interim decisions and the disallowance of project costs);

·            decisions by the PUC and by other agencies and courts on land use, environmental and other permitting issues (such as required corrective actions and restrictions and penalties that may arise, such as with respect to environmental conditions or renewable portfolio standards (RPS));

·            potential enforcement actions by the Office of Thrift Supervision (OTS) (or its regulatory successors, the Office of the Comptroller of the Currency and the Federal Reserve Board) and other governmental authorities (such as consent orders, required corrective actions, restrictions and penalties that may arise, for example, with respect to compliance deficiencies under existing or new banking and consumer protection laws and regulations or with respect to capital adequacy);

·            ability to recover and earn on increasing costs and capital investments not covered by revenue adjustment mechanisms;

·            changes in accounting principles applicable to HEI, HECO, ASB and their subsidiaries, including the adoption of International Financial Reporting Standards or new U.S. accounting standards, the potential discontinuance of regulatory accounting and the effects of potentially required consolidation of variable interest entities (VIEs) or required capital lease accounting for PPAs with IPPs;

·            changes by securities rating agencies in their ratings of the securities of HEI and HECO and the results of financing efforts;

·            faster than expected loan prepayments that can cause an acceleration of the amortization of premiums on loans and investments and the impairment of mortgage servicing assets of ASB;

·            changes in ASB’s loan portfolio credit profile and asset quality which may increase or decrease the required level of allowance for loan losses and charge-offs;

·            changes in ASB’s deposit cost or mix which may have an adverse impact on ASB’s cost of funds;

·            the final outcome of tax positions taken by HEI, HECO, ASB and their subsidiaries;

PART I

ITEM 1.                BUSINESS

HEI Consolidated

HEI and subsidiaries and lines of business.  HEI was incorporated in 1981 under the laws of the State of Hawaii and is a holding company with its principal subsidiaries engaged in electric utility and banking businesses operating primarily in the State of Hawaii. HEI’s predecessor, HECO, was incorporated under the laws of the Kingdom of Hawaii (now the State of Hawaii) on October 13, 1891. As a result of a 1983 corporate reorganization, HECO became an HEI subsidiary and common shareholders of HECO became common shareholders of HEI.

HECO and its operating utility subsidiaries, Hawaii Electric Light Company, Inc. (HELCO) and Maui Electric Company, Limited (MECO), are regulated electric public utilities. HECO also owns all the common securities of HECO Capital Trust III (a Delaware statutory trust), which was formed to effect the issuance of $50 million of cumulative quarterly income preferred securities in 2004, for the benefit of HECO, HELCO and MECO. In December 2002, HECO formed a subsidiary, Renewable Hawaii, Inc., to invest in renewable energy projects, but has made no investments and has been inactive recently. In September 2007, HECO formed another subsidiary, Uluwehiokama Biofuels Corp. (UBC), to invest in a biodiesel refining plant to be built on the island of Maui, which project has been terminated.

Besides HECO and its subsidiaries, HEI also currently owns directly or indirectly the following subsidiaries: American Savings Holdings, Inc. (ASHI) (a holding company) and its subsidiary, ASB; Pacific Energy Conservation Services, Inc. (PECS); HEI Properties, Inc. (HEIPI); HEI Investments, Inc.; Hawaiian Electric Industries Capital Trusts II and III (formed in 1997 to be available for trust securities financings); and The Old Oahu Tug Service, Inc. (TOOTS).

ASB, acquired by HEI in 1988, is one of the largest financial institutions in the State of Hawaii with assets of $4.8 billion as of December 31, 2010.

HEIPI, whose predecessor company was formed in February 1998, holds venture capital investments (in companies based in Hawaii and on the U.S. mainland) with a carrying value of $1.3 million as of December 31, 2010.

PECS was formed in 1994 and was a contract services company providing windfarm operational and maintenance services to an affiliated electric utility that ceased such services when the windfarm was dismantled in 2010. The Company expects to dissolve PECS in 2011.

In November 1999, Hawaiian Tug & Barge Corp. (HTB) sold substantially all of its operating assets and the stock of Young Brothers, Limited (YB) for a nominal gain, changed its name to TOOTS and ceased maritime freight transportation operations. TOOTS currently administers certain employee and retiree-related benefits programs and monitors matters related to its former operations and the operations of its former subsidiary.

For additional information about the Company required by this item, see HEI’s “Management’s Discussion and Analysis of Financial Condition and Results of Operations” (HEI’s MD&A), HEI’s “Quantitative and Qualitative Disclosures about Market Risk” and HEI’s Consolidated Financial Statements (including Note 2, “Segment financial information”), and also see HECO’s “Management’s Discussion and Analysis of Financial Condition and Results of Operations” (HECO’s MD&A) and HECO’s Consolidated Financial Statements and HECO’s “Quantitative and Qualitative Disclosures About Market Risk,” which are incorporated by reference to HECO Exhibit 99.2.

The Company’s website address is www.hei.com. The information on the Company’s website is not incorporated by reference in this annual report on Form 10-K unless, and except to the extent, specifically incorporated herein by reference. HEI and HECO currently make available free of charge through this website their annual reports on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K and all amendments to those reports (since 1994) as soon as reasonably practicable after such material is electronically filed with, or furnished to, the SEC. HEI and HECO intend to continue to use HEI’s website as a means of disclosing additional information. Such disclosures will be included on HEI’s website under the

Table of Contents

headings “Company Overview” and “News & Events” in the Investor Relations section. Accordingly, investors should routinely monitor such portions of HEI’s website, in addition to following HEI’s, HECO’s and ASB’s press releases, SEC filings and public conference calls and webcasts. Investors may also wish to refer to the PUC website at dms.puc.hawaii.gov/dms in order to review documents filed with and issued by the PUC. No information at the PUC website is incorporated herein by reference.

Commitments and contingencies.  See “HEI Consolidated—Liquidity and capital resources —Selected contractual obligations and commitments” in HEI’s MD&A and HECO’s “Commitments and contingencies” below.

Regulation.  HEI and HECO are each holding companies within the meaning of the Public Utility Holding Company Act of 2005 and implementing regulations (2005 Act) and filed a required notification of that status on February 21, 2006. The 2005 Act requires holding companies and their subsidiaries to grant the Federal Energy Regulatory Commission (FERC) access to books and records relating to FERC’s jurisdictional rates. FERC has granted HEI and HECO a waiver from its record retention, accounting and reporting requirements, effective May 2006.

HEI is subject to an agreement entered into with the PUC (the PUC Agreement) which, among other things, requires HEI to provide the PUC with periodic financial information and other reports concerning intercompany transactions and other matters. It also prohibits the electric utilities from loaning funds to HEI or its nonutility subsidiaries and from redeeming common stock of the electric utility subsidiaries without PUC approval. Further, the PUC could limit the ability of the electric utility subsidiaries to pay dividends on their common stock. See “Restrictions on dividends and other distributions” and “Electric utility—Regulation” below.

As a result of the acquisition of ASB, HEI and ASHI are subject to OTS registration, supervision and reporting requirements as savings and loan holding companies. In the event the OTS has reasonable cause to believe that any activity of HEI or ASHI constitutes a serious risk to the financial safety, soundness or stability of ASB, the OTS is authorized under the Home Owners’ Loan Act of 1933, as amended, to impose certain restrictions on HEI, ASHI and/or any of their subsidiaries. Possible restrictions include precluding or limiting: (i) the payment of dividends by ASB; (ii) transactions between ASB, HEI or ASHI, and their subsidiaries or affiliates; and (iii) the activities of ASB that might expose ASB to the liabilities of HEI and/or ASHI and their other affiliates. See “Restrictions on dividends and other distributions” below.

OTS regulations generally prohibit savings and loan holding companies and their nonthrift subsidiaries from engaging in activities other than those which are specifically enumerated in the regulations. However, the OTS regulations provide for an exemption which is available to HEI and ASHI if ASB satisfies the qualified thrift lender (QTL) test discussed under “Bank—Regulation—Qualified thrift lender test.” ASB met the QTL test at all times during 2010; however, the failure of ASB to satisfy the QTL test in the future could result in a need for HEI to divest ASB. As a result of the enactment of the Dodd-Frank Act, supervision and regulation of HEI, as a thrift holding company, will move to the Federal Reserve, and supervision and regulation of ASB, as a federally chartered savings bank, will move to the Office of the Comptroller of the Currency (OCC) in July 2011 (unless the date is extended). HEI is also affected by provisions of the Dodd-Frank Act relating to corporate governance and executive compensation, including provisions requiring shareholder “say on pay” and “say on pay frequency” votes, mandating additional disclosures concerning executive compensation and compensation consultants and advisors, further restricting proxy voting by brokers in the absence of instructions and permitting the SEC to adopt rules in its discretion requiring public companies under specified conditions to include shareholder nominees in management’s proxy solicitation materials. See “Bank—Legislation and regulation” in HEI’s MD&A for a discussion of the effects of the Dodd-Frank Act on HEI and ASB.

Restrictions on dividends and other distributions.  HEI is a legal entity separate and distinct from its various subsidiaries. As a holding company with no significant operations of its own, HEI’s principal sources of funds are dividends or other distributions from its operating subsidiaries, borrowings and sales of equity. The rights of HEI and, consequently, its creditors and shareholders, to participate in any distribution of the assets of any of its subsidiaries are subject to the prior claims of the creditors and preferred shareholders of such subsidiary, except to the extent that claims of HEI in its capacity as a creditor are recognized as primary.

Table of Contents

The abilities of certain of HEI’s subsidiaries to pay dividends or make other distributions to HEI are subject to contractual and regulatory restrictions. Under the PUC Agreement, in the event that the consolidated common stock equity of the electric utility subsidiaries falls below 35% of the total capitalization of the electric utilities (including the current maturities of long-term debt, but excluding short-term borrowings), the electric utility subsidiaries would, absent PUC approval, be restricted in their payment of cash dividends to 80% of the earnings available for the payment of dividends in the current fiscal year and preceding five years, less the amount of dividends paid during that period. The PUC Agreement also provides that the foregoing dividend restriction shall not be construed as relinquishing any right the PUC may have to review the dividend policies of the electric utility subsidiaries. As of December 31, 2010, the consolidated common stock equity of HEI’s electric utility subsidiaries was 55% of their total capitalization (as calculated for purposes of the PUC Agreement). As of December 31, 2010, HECO and its subsidiaries had common stock equity of $1.3 billion of which approximately $588 million was not available for transfer to HEI without regulatory approval.

The ability of ASB to make capital distributions to HEI and other affiliates is restricted under federal law. Subject to a limited exception for stock redemptions that do not result in any decrease in ASB’s capital and would improve ASB’s financial condition, ASB is prohibited from declaring any dividends, making any other capital distributions, or paying a management fee to a controlling person if, following the distribution or payment, ASB would be deemed to be undercapitalized, significantly undercapitalized or critically undercapitalized. See “Bank—Regulation—Prompt corrective action.” All capital distributions are subject to a prior indication of no objection by the OTS (and by the OCC from July 2011, unless the date is extended). Also see Note 13 to HEI’s Consolidated Financial Statements.

HEI and its subsidiaries are also subject to debt covenants, preferred stock resolutions and the terms of guarantees that could limit their respective abilities to pay dividends. The Company does not expect that the regulatory and contractual restrictions applicable to HEI and/or its subsidiaries will significantly affect the operations of HEI or its ability to pay dividends on its common stock.

Environmental regulation.  HEI and its subsidiaries are subject to federal and state statutes and governmental regulations pertaining to water quality, air quality and other environmental factors. See the “Environmental regulation” discussions in the “Electric utility” and “Bank” sections below.

Securities ratings.  See the Standard & Poor’s (S&P) and Moody’s Investors Service’s (Moody’s) ratings of HEI’s and HECO’s securities and discussion under “Liquidity and capital resources” (both “HEI Consolidated” and “Electric utility”) in HEI’s MD&A. These ratings reflect only the view, at the time the ratings are issued, of the applicable rating agency from whom an explanation of the significance of such ratings may be obtained. There is no assurance that any such credit rating will remain in effect for any given period of time or that such rating will not be lowered, suspended or withdrawn entirely by the applicable rating agency if, in such rating agency’s judgment, circumstances so warrant. Any such lowering, suspension or withdrawal of any rating may have an adverse effect on the market price or marketability of HEI’s and/or HECO’s securities, which could increase the cost of capital of HEI and HECO. Neither HEI nor HECO management can predict future rating agency actions or their effects on the future cost of capital of HEI or HECO.

Revenue bonds are issued by the Department of Budget and Finance of the State of Hawaii for the benefit of HECO and its subsidiaries, but the source of their repayment are the unsecured obligations of HECO and its subsidiaries under loan agreements and notes issued to the Department, including HECO’s guarantees of its subsidiaries’ obligations. The payment of principal and interest due on revenue bonds currently outstanding and issued prior to 2009 are insured - see the discussion of the downgrades of the ratings of the insurers under “Electric Utility—Liquidity and capital resources” in HEI’s MD&A.

Employees.  The Company had full-time employees as follows:

Table of Contents

The employees of HEI and its direct and indirect subsidiaries, other than the electric utilities, are not covered by any collective bargaining agreement. A substantial number of employees of HECO and its subsidiaries are covered by collective bargaining agreements, which have been recently renegotiated, but are subject to ratification by the union employees. See “Collective bargaining agreements” in Note 3 to HEI’s Consolidated Financial Statements.

Properties.  HEI leases office space from nonaffiliated lessors in downtown Honolulu under leases that expire in March 2016. HEI also subleases office space in a downtown Honolulu building leased by HECO under a lease that expires in November 2021, with an option to extend to November 2024. See the discussions under “Electric Utility” and “Bank” below for a description of properties owned by HEI subsidiaries.

Electric utility

HECO and subsidiaries and service areas.  HECO, HELCO and MECO are regulated operating electric public utilities engaged in the production, purchase, transmission, distribution and sale of electricity on the islands of Oahu; Hawaii; and Maui, Lanai and Molokai, respectively. HECO acquired MECO in 1968 and HELCO in 1970. In 2010, the electric utilities’ revenues and net income amounted to approximately 89% and 67%, respectively, of HEI’s consolidated revenues and net income, compared to approximately 88% and 96% in 2009 and approximately 89% and 102% in 2008, respectively.

The islands of Oahu, Hawaii, Maui, Lanai and Molokai have a combined population estimated at 1.2 million, or approximately 95% of the Hawaii population, and comprise a service area of 5,766 square miles. The principal communities served include Honolulu (on Oahu), Hilo and Kona (on Hawaii) and Wailuku and Kahului (on Maui). The service areas also include numerous suburban communities, resorts, U.S. Armed Forces installations and agricultural operations. The state has granted HECO, HELCO and MECO nonexclusive franchises, which authorize the utilities to construct, operate and maintain facilities over and under public streets and sidewalks. Each of these franchises will continue in effect for an indefinite period of time until forfeited, altered, amended or repealed.

For additional information about HECO, see HECO’s MD&A, HECO’s “Quantitative and Qualitative Disclosures about Market Risk” and HECO’s Consolidated Financial Statements.

Sales of electricity.  The following table sets forth the number of electric customer accounts as of December 31, 2010, 2009 and 2008 and electric sales revenues by company for each of the years then ended:

* As of December 31.

Seasonality.  Kilowatthour (KWH) sales of HECO and its subsidiaries follow a seasonal pattern, but they do not experience the extreme seasonal variation due to extreme weather variations like some electric utilities on the U.S. mainland. KWH sales in Hawaii tend to increase in the warmer, more humid months, probably as a result of increased demand for air conditioning.

Significant customers.  HECO and its subsidiaries derived approximately 10% in 2010, 2009 and 2008 of their operating revenues from the sale of electricity to various federal government agencies.

Under a Basic Ordering Agreement (BOA) with the federal Department of Defense (DOD) entered into in 2007, which expires in 2012, and earlier BOAs and other agreements, HECO has completed energy conservation and other projects for federal agencies over the years.  The Navy Facilities Engineering Command Pacific developed a Hawaii Navy Energy Program which establishes energy goals for meeting energy reduction standards set forth in the Energy Independence and Security Act of 2007 which required agencies to reduce energy consumption by 3% a year, or 30% by the end of 2015, beginning in 2006. The Navy must also meet renewable energy requirements set forth in the National Defense Authorization Act of

4

Table of Contents

2007 (by 2025, 25% of the energy consumed at an installation must be produced or procured from renewable energy sources).

The Energy Policy Act of 2005 mandated that federal buildings reduce energy consumption by up to 20% by fiscal year 2015 relative to base fiscal year 2003 consumption to the extent that these measures are cost effective. The Act also establishes energy conservation goals at the state level for federally funded programs, stricter conservation measures for a variety of large energy-consuming products and tax credits for energy efficient homes, solar energy, fuel cells and microturbine power plants; and includes other energy-related provisions. Executive Order 13514, adopted in 2009, expanded upon energy reduction and environmental performance requirements set forth in Executive Orders 13123, 13149 and 13423. The Order sets the framework for sustainability goals for Federal agencies including making improvements in environmental, energy, and economic performance. The Order requires agencies to set agency-defined targets for the reduction of greenhouse gas emissions, as well as measure and manage steps to meet those targets. HECO continues to work with various federal agencies to implement measures that will help them achieve their energy reduction objectives.

Energy Agreement, energy efficiency and decoupling.  On October 20, 2008, the Governor, the Hawaii Department of Business Economic Development and Tourism, the Consumer Advocate and the utilities entered into an Energy Agreement pursuant to which they agreed to undertake a number of initiatives to help accomplish the objectives of the Hawaii Clean Energy Initiative (HCEI) established under a memorandum of understanding between the State of Hawaii and U.S. Department of Energy. The primary objective of the HCEI and Energy Agreement is to reduce Hawaii’s dependence on imported fuels through substantial increases in the use of renewable energy and implementation of new programs intended to secure greater energy efficiency and conservation. See Note 3 of HEI’s Consolidated Financial Statements.

One of the initiatives under the Energy Agreement was advanced when, in 2009, the state legislature enacted Act 155, which gave the PUC the authority to establish an Energy Efficiency Portfolio Standard (EEPS) goal of saving 4,300 GWH of electricity use reductions by 2030. The PUC opened an EEPS docket, which is on-going. Another of the initiatives was advanced when, on December 29, 2010, the PUC approved the implementation of revenue decoupling for HECO under which HECO is allowed to recover PUC-approved revenue requirements without being dependent on the amount of electricity sold. See “Decoupling proceeding” under “Electric utility” in HEI’s MD&A. Both the establishment of an EEPS and the implementation of revenue decoupling could have an impact on sales. However, neither HEI nor HECO management can predict with certainty the impact of these or other governmental mandates, the HCEI or the Energy Agreement on HEI’s or HECO’s future financial condition, results of operations or cash flows.

(2)         Nonutility generators— HECO: 208 MW (Kalaeloa Partners, L.P., oil-fired), 180 MW (AES Hawaii, Inc., coal-fired) and 46 MW (HPower, refuse-fired); HELCO: 30 MW (Puna Geothermal Venture, geothermal) and 60 MW (Hamakua Energy Partners, L.P., oil-fired); MECO: 16 MW (Hawaiian Commercial & Sugar Company, primarily bagasse-fired).

(3)   Noncoincident and nonintegrated.

Generating reliability and reserve margin.  HECO serves the island of Oahu and HELCO serves the island of Hawaii. MECO has three separate electrical systems—one each on the islands of Maui, Molokai and Lanai. HECO, HELCO and MECO have isolated electrical systems that are not currently interconnected to each other or to any other electrical grid and, thus, each maintains a higher level of reserve generation than is typically carried by interconnected mainland U.S. utilities, which are able to share reserve capacity. These higher levels of reserve margins are required to meet peak electric demands, to provide for scheduled maintenance of generating units (including the units operated by IPPs relied upon for firm capacity) and to allow for the forced outage of the largest generating unit in the system.

See “Adequacy of supply” in HEI’s MD&A under “Electric utility.”

Nonutility generation.  The Company has supported state and federal energy policies which encourage the development of renewable energy sources that reduce the use of fuel oil. The Company’s renewable energy sources and potential sources range from wind, solar, photovoltaic, geothermal, wave and hydroelectric power to energy produced by the burning of bagasse (sugarcane waste), municipal waste and other biofuels.

HECO PPAs.  HECO currently has three major PPAs. In March 1988, HECO entered into a PPA with AES Barbers Point, Inc. (now known as AES Hawaii, Inc. (AES Hawaii)), a Hawaii-based, indirect subsidiary of The AES Corporation. The agreement with AES Hawaii, as amended, provides that, for a period of 30 years beginning September 1992, HECO will purchase 180 megawatts (MW) of firm capacity. The AES Hawaii 180 MW coal-fired cogeneration plant utilizes a “clean coal” technology and is designed to sell sufficient steam to be a “Qualifying Facility” (QF) under the Public Utility Regulatory Policies Act of 1978 (PURPA).

In October 1988, HECO entered into an agreement with Kalaeloa Partners, L.P. (Kalaeloa), a limited partnership, which, through affiliates, contracted to design, build, operate and maintain a QF. The agreement with Kalaeloa, as amended, provided that HECO would purchase 180 MW of firm capacity for a period of 25 years beginning in May 1991. The Kalaeloa facility is a combined-cycle operation, consisting of two oil-fired combustion turbines burning low sulfur fuel oil (LSFO) and a steam turbine that utilizes waste heat from the combustion turbines, and is designed to sell sufficient steam to be a QF. Following two additional amendments, effective in 2005, Kalaeloa currently supplies HECO with 208 MW of firm capacity.

HECO also entered into a PPA in March 1986 and a firm capacity amendment in April 1991 with the City and County of Honolulu with respect to a refuse-fired plant (HPower). The HPower facility currently supplies HECO with 46 MW of firm capacity. Under the amendment, HECO will purchase firm capacity until mid-2015. HPOWER is proceeding with its plan to expand its facility in order to provide an additional 27 MW net to HECO beginning in 2012.

HECO purchases energy on an as-available basis from three nonutility generators, two of which are qualifying cogeneration facilities at two oil refineries, Chevron USA, Inc. (10 MW) and Tesoro Hawaii Corporation (19 MW). These two contracts continue unless a party elects to terminate upon 90 days notice. The third nonutility generator, Kahuku Wind Power (30 MW), is a wind facility classified as an eligible resource under Hawaii’s RPS Law and as a QF under PURPA. The contract with Kahuku Wind Power is for a period of 20 years following the commercial operations date, which is expected to be in the first quarter of 2011.

The PUC has allowed rate recovery for the purchased energy costs related to HECO’s as-available energy PPAs and for the firm capacity and purchased energy costs related to HECO’s three major PPAs that provide a total of 434 MW of firm capacity, representing 25% of HECO’s total net generating and firm purchased capacity on Oahu as of December 31, 2010.

HELCO and MECO PPAs.  As of December 31, 2010, HELCO has PPAs for 90 MW and MECO has PPAs for 16 MW (includes 4 MW of system protection) of firm capacity, which PPAs have been approved by the PUC.

HELCO has a 35-year PPA with Puna Geothermal Venture (PGV) for 30 MW of firm capacity from its geothermal steam facility, which will expire on December 31, 2027. Since April 2009, PGV’s output had been reduced due to problems with two of its production wells, but its output was restored to 30 MW in June 2010. In February 2011, HELCO and PGV amended the current PPA for the pricing on a portion of the energy payments and entered into a new PPA for HELCO to acquire an additional 8 MW of firm capacity from the facility. Both the amendment and the new PPA are subject to PUC approval.

In October 1997, HELCO entered into an agreement with Encogen, which has been succeeded by Hamakua Energy Partners, L. P. (HEP). The agreement requires HELCO to purchase up to 60 MW (net) of firm capacity for a period of 30 years, expiring on December 31, 2030. The dual-train combined-cycle DTCC facility, which primarily burns naphtha, consists of two oil-fired combustion turbines and a steam turbine that utilizes waste heat from the combustion turbines.

MECO has a PPA with Hawaiian Commercial & Sugar Company (HC&S) for 16 MW of firm capacity. The HC&S generating units primarily burn bagasse (sugar cane waste) along with secondary fuels of diesel oil or coal. The PPA runs through December 31, 2014, and from year to year thereafter, subject to termination on or after December 31, 2014 on not less than two years’ prior written notice by either party.

HELCO and MECO purchase energy on an as-available basis from a number of nonutility generators, including hydroelectric facilities, windfarms and photovoltaic systems. The PUC has allowed rate recovery for the firm capacity and purchased energy costs for HELCO’s and MECO’s approved firm capacity and as-available energy PPAs.

Fuel oil usage and supply.  The rate schedules of the Company’s electric utility subsidiaries include ECACs under which electric rates (and consequently the revenues of the electric utility subsidiaries generally) are adjusted for changes in the weighted-average price paid for fuel oil and certain components of purchased power, and the relative amounts of company-generated power and purchased power. See discussion of rates and issues relating to the ECAC below under “Rates,” and “Electric utility—Certain factors that may affect future results and financial condition—Regulation of electric utility rates” and “Electric utility—Material estimates and critical accounting policies—Revenues” in HEI’s MD&A.

HECO’s steam generating units burn LSFO. HECO’s combustion turbine peaking units burn diesel fuel (diesel) and B99 grade biodiesel (biodiesel) and diesel engine generating units burn diesel. HECO’s new CIP CT-1 is being operated exclusively on biodiesel. A HECO steam unit is currently employed in a co-firing project to test burn mixtures of LSFO and crude palm oil purchased under a PUC-approved spot contract with Sime Darby Biodiesel Sdn. Bhd. (Sime Darby) dated June 3, 2009 and physically received in December 2010.

Table of Contents

MECO’s and HELCO’s steam generating units burn medium sulfur fuel oil (MSFO) and their combustion turbine and diesel engine generating units burn diesel and biodiesel. A MECO combustion turbine generating unit is being prepared to test fire biodiesel for an assessment of the longer-term impact on unit performance. This biodiesel is expected to be supplied to MECO in early 2011 by Sime Darby under the terms of a spot contract dated June 26, 2009.

The diesel supplies acquired by the Lanai Division of MECO are purchased under the provisions of a contract with a local petroleum wholesaler, Lanai Oil Co., Inc., which provides for automatic one-year term extensions unless terminated by either party with 180 days notice. On May 26, 2010, MECO and Lanai Oil amended the fuel supply contract to provide for the supply of the Ultra Low Sulfur grade of diesel, which was to be consumed in the new Manele Bay combined heat and power (CHP) facility and other of Lanai Division’s generating units, in accordance with State and federal regulations applicable October 1, 2010. In October 2010, the PUC approved this amendment.

See the fuel oil commitments information set forth in the “Fuel contracts” section in Note 3 to HEI’s Consolidated Financial Statements, including discussions of contracts with Chevron Products Company, a division of Chevron USA, Inc. (Chevron), Tesoro Hawaii Corporation (Tesoro), Renewable Energy Group Marketing & Logistics Group LLC (REG) and Aina Koa Pono-Ka’u LLC.

The following table sets forth the average cost of fuel oil used by HECO, HELCO and MECO to generate electricity in the years 2010, 2009 and 2008:

The average per-unit cost of fuel oil consumed to generate electricity for HECO, HELCO and MECO reflects a different volume mix of fuel types and grades as follows:

In general, MSFO is the least costly fuel, biodiesel and diesel are the most expensive fuels and the price of LSFO falls in-between on a per-barrel basis. During 2010, the prices of LSFO and diesel trended higher through the first half of 2010 and then weakened in the fall months before rising at year-end. The prices of these fuels rose approximately by 30% and 15%, respectively, over the course of the year. MSFO and biodiesel prices exhibited a less pronounced volatility during 2010 as the per unit prices of each increased steadily, if gradually, such that their prices ended the period about 6% above their respective starting places.

In December 2000, HELCO and MECO executed contracts of private carriage with Hawaiian Interisland Towing, Inc. (HITI) for the employment of a double-hull tank barge for the shipment of MSFO and diesel supplies from their fuel suppliers’ facilities on Oahu to storage locations on the islands of Hawaii and Maui, respectively, commencing January 1, 2002. The contracts were extended for a second 5-year term commencing January 1, 2007 and contain options for two additional 5-year extensions. On August 14, 2007 the equity interest of Smith Maritime, Ltd., the parent company of HITI, was acquired by a subsidiary of K-Sea Transportation Partners L.P. (K-Sea), which provides refined petroleum products marine transportation, distribution and logistics services in the U.S. domestic marine transportation industry.

K-Sea never takes title to the fuel oil or diesel fuel, but does have custody and control while the fuel is in transit from Oahu. If there were an oil spill in transit, K-Sea is generally contractually obligated to indemnify HELCO and/or MECO for resulting clean-up costs, fines and damages. K-Sea has liability insurance coverage for oil spill related damage in excess of $1 billion. State law provides a cap of $700 million on liability for

releases of heavy fuel oil transported interisland by tank barge. In the event of a release, HELCO and/or MECO may be responsible for any clean-up, damages, and/or fines that K-Sea or its insurance carrier does not cover.

The prices that HECO, HELCO and MECO pay for purchased energy from nonutility generators are generally linked to the price of oil. The AES Hawaii energy prices vary primarily with an inflation index. The energy prices for Kalaeloa, which purchases LSFO from Tesoro, vary primarily with world LSFO prices. The HPower, HC&S and PGV energy prices are based on the electric utilities’ respective PUC-filed short-run avoided energy cost rates (which vary with their respective composite fuel costs), subject to minimum floor rates specified in their approved PPAs. HEP energy prices vary primarily with HELCO’s diesel costs.

The utilities estimate that 75% of the net energy they will generate and purchase in 2011 will be generated from the burning of fossil fuel oil. HECO generally maintains an average system fuel inventory level equivalent to 47 days of forward consumption. HELCO and MECO generally maintain an average system fuel inventory level equivalent to approximately one month’s supply of both MSFO and diesel. The PPAs with AES Hawaii and HEP require that they maintain certain minimum fuel inventory levels.

Rates.  HECO, HELCO and MECO are subject to the regulatory jurisdiction of the PUC with respect to rates, issuance of securities, accounting and certain other matters. See “Regulation” below.

All rate schedules of HECO and its subsidiaries contain ECACs as described previously. Under current law and practices, specific and separate PUC approval is not required for each rate change pursuant to automatic rate adjustment clauses previously approved by the PUC. All other rate increases require the prior approval of the PUC after public and contested case hearings. PURPA requires the PUC to periodically review the ECACs of electric and gas utilities in the state, and such clauses, as well as the rates charged by the utilities generally, are subject to change.

See “Electric utility—Most recent rate requests,” “Electric utility—Decoupling proceeding,” “Electric utility—Certain factors that may affect future results and financial condition—Regulation of electric utility rates” and “Electric utility—Material estimates and critical accounting policies—Revenues” in HEI’s MD&A and “Interim increases” and “Major projects—Campbell Industrial Park combustion turbine No. 1 and transmission line” under “Commitments and contingencies” in Note 3 to HEI’s Consolidated Financial Statements.

Public Utilities Commission and Division of Consumer Advocacy of the Department of Commerce and Consumer Affairs of the State of Hawaii.  On February 3, 2011, the Governor of the State of Hawaii announced the appointment of State Representative Hermina Morita as the Chairman of the PUC (for a term that expires in June 2014), subject to confirmation by the State Senate. The other commissioners are Carlito P. Caliboso (for a term that expires in June 2016), an attorney previously in private practice, and John E. Cole (for a term that expires in June 2012), who previously served as the Executive Director of the Division of Consumer Advocacy.

Since January 2011, the Executive Director of the Division of Consumer Advocacy has been Jeffrey T. Ono, an attorney previously in private practice.

Competition.  See “Electric utility—Certain factors that may affect future results and financial condition—Competition” in HEI’s MD&A.

Electric and magnetic fields.  The generation, transmission and use of electricity produces low-frequency (50Hz-60Hz) electrical and magnetic fields (EMF). While EMF has been classified as a possible human carcinogen by more than one public health organization and remains the subject of ongoing studies and evaluations, no definite causal relationship between EMF and health risks has been clearly demonstrated to date and there are no federal standards in the U.S. limiting occupational or residential exposure to 50Hz-60Hz EMF. HECO and its subsidiaries are continuing to monitor the ongoing research and continue to participate in utility industry funded studies on EMF and, where technically feasible and economically reasonable, continue to pursue a policy of prudent avoidance in the design and installation of new transmission and distribution facilities. Management cannot predict the impact, if any, the EMF issue may have on HECO, HELCO and MECO in the future.

Global climate change and greenhouse gas emissions reduction.  The Company shares the concerns of many regarding the potential effects of global warming and the human contributions to this phenomenon, including burning of fossil fuels for electricity production, transportation, manufacturing and agricultural activities, as well as deforestation. Recognizing that effectively addressing global warming requires commitment by the private sector, all levels of government, and the public, the Company is committed to taking direct action to mitigate greenhouse gas emissions from its operations. See “Environmental regulation—Global climate change and greenhouse gas emissions reduction” under “Commitments and contingencies” in Note 3 to HEI’s Consolidated Financial Statements.

Legislation.  See “Electric utility—Legislation and regulation” in HEI’s MD&A.

Commitments and contingencies.  See “Selected contractual obligations and commitments” in HECO’s MD&A and “Electric utility—Certain factors that may affect future results and financial condition—Other regulatory and permitting contingencies” in HEI’s MD&A, Item 1A. Risk Factors, and Note 3 to HEI’s Consolidated Financial Statements for a discussion of important commitments and contingencies.

Regulation.  The PUC regulates the rates, issuance of securities, accounting and certain other aspects of the operations of HECO and its electric utility subsidiaries. See the previous discussion under “Rates” and the discussions under “Electric utility—Results of operations—Most recent rate requests” and “Electric utility—Certain factors that may affect future results and financial condition—Regulation of electric utility rates” in HEI’s MD&A.

Any adverse decision or policy made or adopted by the PUC, or any prolonged delay in rendering a decision, could have a material adverse effect on consolidated HECO’s and the Company’s financial condition, results of operations or cash flows.

On October 20, 2008, HECO signed an Energy Agreement (see “Hawaii Clean Energy Initiative” under “Commitments and contingencies” in Note 3 to HEI’s Consolidated Financial Statements) setting forth goals, objectives and actions with the purpose of decreasing Hawaii’s dependence on imported fossil fuels through substantial increases in the use of renewable energy and implementation of new programs intended to secure greater energy efficiency and conservation. As a result of the Energy Agreement, numerous PUC proceedings have been initiated, many of which have been completed, as described elsewhere in this report. One of the proceedings has resulted in the adoption of a new framework that will substantially change the manner in which the utilities obtain rate relief. See “Decoupling” in HEI’s MD&A.

In 2009, the State Legislature amended Hawaii’s RPS law to require electric utilities to meet an RPS of 10%, 15%, 25% and 40% by December 31, 2010, 2015, 2020 and 2030, respectively. Energy savings resulting from energy efficiency programs will not count toward the RPS after 2014 (only electrical generation using renewable energy as a source will count). The amended RPS law is consistent with the commitment in the Energy Agreement.

Certain transactions between HEI’s electric public utility subsidiaries (HECO, HELCO and MECO) and HEI and affiliated interests are subject to regulation by the PUC. An “affiliated interest” is defined by statute and includes officers and directors of a public utility, every person owning or holding, directly or indirectly, 10% or more of the voting securities of a public utility, and corporations which have in common with a public utility more than one-third of the directors of that public utility. All contracts (including summaries of unwritten agreements) made on or after July 1, 1988 of $300,000 or more in a calendar year for management, supervisory, construction, engineering, accounting, legal, financial and similar services and for the sale, lease or transfer of property between a public utility and affiliated interests must be filed with the PUC to be effective, and the PUC may issue cease and desist orders if such contracts are not filed. All such “affiliated contracts” for capital expenditures (except for real property) must be accompanied by comparative price quotations from two nonaffiliates, unless the quotations cannot be obtained without substantial expense. Moreover, all transfers of $300,000 or more of real property between a public utility and affiliated interests require the prior approval of the PUC and proof that the transfer is in the best interest of the public utility and its customers. If the PUC, in its discretion, determines that an affiliated contract is unreasonable or otherwise contrary to the public interest, the utility must either revise the contract or risk disallowance of the payments for rate-making purposes. In rate-making proceedings, a utility must also prove the reasonableness of payments made to affiliated interests under any affiliated contract of $300,000 or more by clear and convincing evidence.

In December 1996, the PUC issued an order in a docket that had been opened to review the relationship between HEI and HECO and the effects of that relationship on the operations of HECO. The order adopted the report of the consultant the PUC had retained and ordered HECO to continue to provide the PUC with periodic status reports on its compliance with the PUC Agreement (pursuant to which HEI became the holding company of HECO). HECO files such status reports annually. In the order, the PUC also required HECO, HELCO and MECO to present a comprehensive analysis of the impact that the holding company structure and investments in nonutility subsidiaries have on a case-by-case basis on the cost of capital to each utility in future rate cases and remove any such effects from the cost of capital. The PUC has not disputed, in subsequent rate cases, the presentations made by HECO, HELCO and MECO that there was no evidence that would modify the PUC’s finding that HECO’s access to capital did not suffer as a result of HEI’s involvement in nonutility activities and that HEI’s diversification did not permanently raise or lower the cost of capital incorporated into the rates paid by HECO’s utility customers.

HECO and its electric utility subsidiaries are not subject to regulation by the Federal Energy Regulatory Commission under the Federal Power Act, except under Sections 210 through 212 (added by Title II of PURPA and amended by the Energy Policy Act of 1992), which permit the Federal Energy Regulatory Commission to order electric utilities to interconnect with qualifying cogenerators and small power producers, and to wheel power to other electric utilities. Title I of PURPA, which relates to retail regulatory policies for electric utilities, and Title VII of the Energy Policy Act of 1992, which addresses transmission access, also apply to HECO and its electric utility subsidiaries. HECO and its electric utility subsidiaries are also required to file various operational reports with the Federal Energy Regulatory Commission. The Company cannot predict the extent to which cogeneration or transmission access will reduce its electrical loads, reduce its current and future generating and transmission capability requirements or affect its financial condition, results of operations or cash flows.

Because they are located in the State of Hawaii, HECO and its subsidiaries are exempt by statute from limitations set forth in the Powerplant and Industrial Fuel Use Act of 1978 on the use of petroleum as a primary energy source.

See also “HEI—Regulation” above.

Environmental regulation.  HECO, HELCO and MECO, like other utilities, are subject to periodic inspections by federal, state and, in some cases, local environmental regulatory agencies, including agencies responsible for the regulation of water quality, air quality, hazardous and other waste, and hazardous materials. These inspections may result in the identification of items needing corrective or other action. When the corrective or other necessary action is taken, no further regulatory action is expected. Except as otherwise disclosed in this report (see “Certain factors that may affect future results and financial condition—Environmental matters” for HEI Consolidated, the Electric utility and the Bank sections in HEI’s MD&A and Note 3 to HEI’s Consolidated Financial Statements, which are incorporated herein by reference), the Company believes that each subsidiary has appropriately responded to environmental conditions requiring action and that, as a result of such actions, such environmental conditions will not have a material adverse effect on the Company or HECO.

Water quality controls.  The generating stations, substations and other utility facilities operate under federal and state water quality regulations and permits, including but not limited to the Clean Water Act National Pollution Discharge Elimination System (governing point source discharges, including wastewater and storm water discharges), Underground Injection Control (regulating disposal of wastewater into the subsurface), the Spill Prevention, Control and Countermeasure (SPCC) program, the Oil Pollution Act of 1990 (OPA), and other regulations associated with discharges of oil and other substances to surface water.

OPA governs actual or threatened oil releases and establishes strict and joint and several liability for responsible parties for (1) oil removal costs incurred by the federal government or the state, and (2) damages to natural resources and real or personal property, as well as compensation for certain economic damages. Responsible parties include vessel owners and operators of on-shore facilities. OPA imposes fines and jail terms ranging in severity depending on how the release was caused.

In 2010 and 2011 to date, HECO, HELCO and MECO did not experience any significant petroleum releases. See the discussion concerning the ongoing Honolulu Harbor investigation under “Environmental regulation” in Note 3 to HEI’s Consolidated Financial Statements. Except as otherwise disclosed, the Company believes that each subsidiary’s costs of responding to petroleum releases to date will not have a material adverse effect on the respective subsidiary or the Company.

EPA regulations under OPA also require certain facilities that use or store petroleum to prepare and implement SPCC Plans in order to prevent releases of petroleum to navigable waters of the U.S. Certain of the facilities of HECO, HELCO and MECO subject to the SPCC program (including power plants and certain baseyards) are in compliance with these requirements. The utilities expect to complete and implement their SPCC Plans for other facilities subject to these requirements (principally their substations) by the current compliance deadline of November 10, 2011.

As required by section 316(b) of the Clean Water Act, proposed regulations governing protection of aquatic organisms in cooling water intake structures at three of HECO’s power plants are expected in 2011. Depending on the ultimate regulations adopted by the EPA, the cost of compliance could be significant.

Air quality controls.  The generating stations of the utility subsidiaries operate under air pollution control permits issued by the Department of Health of the State of Hawaii (DOH) and, in a limited number of cases, by the EPA. The entire electric utility industry has been affected by the 1990 amendments to the Clean Air Act (CAA), changes to the National Ambient Air Quality Standard (NAAQS) for ozone, adoption of a NAAQS for fine particulate matter, and the EPA’s 1-hour NAAQS for nitrogen dioxide and sulfur dioxide (adopted in 2010). Regulations are expected to be issued in 2011 proposing Maximum Available Control Technology (MACT) standards for hazardous air pollutants (HAPs) emitted by electrical steam generating units (EGUs) that may be applicable to all HECO steam units. Depending on the HAPs covered by the final regulations and the MACT standards adopted for those HAPs, the cost of compliance for HECO could be significant. By the terms of a federal court consent decree, the EPA is required to issue proposed EGU MACT regulations in March 2011 and final regulations in November 2011. The EPA has also required HELCO (for its Hill Power Plant) and MECO (for its Kahului Power Plant) to develop evaluations of emission controls for units at those plants that the EPA believes contribute to Regional Haze. Depending on final Regional Haze rules that the EPA will issue for Hawaii, the cost of compliance for HELCO and MECO could be significant.

The CAA amendments of 1990, among other things, established a federal operating permits program (in Hawaii known as the Covered Source Permit program) and greatly expanded the hazardous air pollutant program. The more stringent NAAQS will affect new or modified units requiring a permit to construct under the PSD program and the controls necessary to meet the NAAQS.

CAA operating permits (Title V permits) have been issued for all affected generating units.

Hazardous waste and toxic substances controls.  The operations of the electric utility and former freight transportation subsidiaries of HEI are subject to EPA regulations that implement provisions of the Resource Conservation and Recovery Act (RCRA), the Superfund Amendments and Reauthorization Act (SARA) and the Toxic Substances Control Act (TSCA).

RCRA underground storage tank (UST) regulations require all facilities with USTs used for storing petroleum products to comply with leak detection, spill prevention and new tank standard retrofit requirements. All HECO, HELCO and MECO USTs currently meet these standards.

The Emergency Planning and Community Right-to-Know Act under SARA Title III requires HECO, HELCO and MECO to report potentially hazardous chemicals present in their facilities in order to provide the public with information so that emergency procedures can be established to protect the public in the event of hazardous chemical releases. All HECO, HELCO and MECO facilities are in compliance with applicable annual reporting requirements to the State Emergency Planning Commission, the Local Emergency Planning Committee and local fire departments. Since January 1, 1998, the steam electric industry category has been subject to Toxics Release Inventory (TRI) reporting requirements. All HECO, HELCO and MECO facilities are in compliance with TRI reporting requirements.

The TSCA regulations specify procedures for the handling and disposal of polychlorinated biphenyls (PCB), a compound found in some transformer and capacitor dielectric fluids. The TSCA regulations also

13

Table of Contents

apply to responses to releases of PCB to the environment. HECO, HELCO and MECO have instituted procedures to monitor compliance with these regulations and have implemented a program to identify and replace PCB transformers and capacitors in their systems. Management believes that all HECO, HELCO and MECO facilities are currently in compliance with PCB regulations. In April 2010, the EPA issued an Advance Notice of Proposed Rule Making announcing its intent to reassess PCB regulations.

Hawaii’s Environmental Response Law, as amended (ERL), governs releases of hazardous substances, including oil, to the environment in areas within the state’s jurisdiction. Responsible parties under the ERL are jointly, severally and strictly liable for a release of a hazardous substance. Responsible parties include owners or operators of a facility where a hazardous substance comes to be located and any person who at the time of disposal of the hazardous substance owned or operated any facility at which such hazardous substance was disposed.

HECO, HELCO and MECO periodically identify leaking petroleum-containing equipment such as USTs, piping and transformers. In a few instances, small amounts of PCBs have been identified in the leaking equipment. Each subsidiary reports releases from such equipment when and as required by applicable law and addresses impacts due to the releases in compliance with applicable regulatory requirements.

Research and development.  HECO and its subsidiaries expensed approximately $4.0 million, $4.4 million and $4.0 million in 2010, 2009 and 2008, respectively, for research and development (R&D). In 2010, 2009 and 2008, the electric utilities’ contributions to the Electric Power Research Institute accounted for approximately half of the R&D expenses. There were also utility expenditures in 2010, 2009 and 2008 related to new technologies, energy efficiency and conservation, demand response, customer use and pricing (e.g., peak pricing and tiered rates based on usage), biofuels, energy storage, electric and hybrid plug in vehicles and other renewables (e.g., wind and solar power integration and solar resource evaluation).

Properties.

HECO owns and operates four generating plants on the island of Oahu at Honolulu, Waiau, Kahe and Campbell Industrial Park. These plants have an aggregate net generating capability of 1,321.6 MW as of December 31, 2010. The four plants are situated on HECO-owned land having a combined area of 535 acres and one 3.5-acre parcel of land under a lease expiring December 31, 2018. In addition, HECO owns a total of 132 acres of land on which substations, transformer vaults, distribution baseyards and the Kalaeloa cogeneration facility are located.

HECO owns overhead transmission lines, overhead distribution lines, underground cables, poles (fully owned or jointly owned) and steel or aluminum high voltage transmission towers. The transmission system operates at 46 kilovolt (kV) and 138 kV.

HECO owns buildings and approximately 11.6 acres of land located in Honolulu which houses its operating, engineering and information services departments and a warehousing center. It also leases an office building and certain office spaces in Honolulu. The lease for the office building expires in November 2021, with an option to extend through November 2024. The leases for certain office spaces expire on various dates from December 31, 2011 through November 30, 2017 with options to extend to various dates through July 31, 2021.

HECO owns land at Campbell Industrial Park (CIP) used to situate central fuel storage facilities adjacent to its CIP CT-1 generating unit facility with an aggregate usable capacity of 786,632 barrels of fuel, which land is included in the power plant acreage above. HECO also has fuel storage facilities at each of its plant sites with a combined usable capacity of 869,093 barrels, as well as underground fuel pipelines that transport fuel from HECO’s central fuel storage at CIP to fuel storage facilities at HECO’s generating stations at Waiau and Kahe. HECO also owns a fuel storage facility at Iwilei, which receives fuel trucked from the central storage facility, with a combined usable capacity of 76,735 barrels, and an under-ground pipeline that transports fuel from that site to its Honolulu generating station.

HELCO owns and operates five generating plants on the island of Hawaii, two at Hilo and one at each of Waimea, Keahole and Puna, along with distributed generators at substation sites. These plants have an aggregate net generating capability of 195.5 MW as of December 31, 2010 (excluding several small run-of-river hydro units and a small windfarm). The plants are situated on HELCO-owned land having a combined

Table of Contents

area of approximately 44 acres. The distributed generators are located within HELCO-owned substation sites having a combined area of approximately 4 acres. HELCO also owns fuel storage facilities at these sites with a total maximum usable capacity of 66,387 barrels of bunker oil, and 83,819 barrels of diesel. There are an additional 30,341 barrels of diesel and 22,770 barrels of bunker oil storage capacity for HELCO-owned fuel off-site at Chevron-owned terminalling facilities. HELCO pays a storage fee to Chevron and has no other interest in the property, tanks or other infrastructure situated on Chevron’s property. HELCO also owns 6 acres of land in Kona, which is used for a baseyard, and one acre of land in Hilo, which houses its accounting, customer services and administrative offices. HELCO also leases 3.7 acres of land for its baseyard in Hilo under a lease expiring in 2030. In addition, HELCO owns a total of approximately 100 acres of land, and leases a total of approximately 8.5 acres of land, on which hydro facilities, substations and switching stations, microwave facilities, and transmission lines are located. The deeds to the sites located in Hilo contain certain restrictions, but the restrictions do not materially interfere with the use of the sites for public utility purposes.

MECO owns and operates two generating plants on the island of Maui, at Kahului and Maalaea, with an aggregate net generating capability of 246.3 MW as of December 31, 2010. The plants are situated on MECO-owned land having a combined area of 28.6 acres. MECO also owns fuel oil storage facilities at these sites with a total maximum usable capacity of 176,355 barrels of fuel. MECO owns two 1 MW stand-by diesel generators and a 6,000 gallon fuel storage tank located in Hana. MECO owns 65.7 acres of undeveloped land at Waena. Most of this Waena land is used for agricultural purposes by the former landowner under an amended license agreement, which is effective on a month-to-month basis, but terminable by either party upon 30 days written notice until the area is required for development by MECO for utility purposes (e.g., proposed biofuel plant), or until December 31, 2011, whichever occurs first.

MECO’s administrative offices and engineering and distribution departments are located on 9.1 acres of MECO-owned land in Kahului.

MECO also owns and operates smaller distribution systems, generation systems (with an aggregate net capability of 21.9 MW as of December 31, 2010) and fuel storage facilities on the islands of Lanai and Molokai, primarily on land owned by MECO.

Other properties.  The utilities own transmission lines, distribution lines, underground cables, poles (some jointly) and towers. Electric lines are located over or under public and nonpublic properties. Lines are added when needed to serve increased loads and/or for reliability reasons. In some design districts on Oahu, lines must be placed underground. Under Hawaii law, the PUC generally must determine whether new 46 kV, 69 kV or 138 kV lines can be constructed overhead or must be placed underground.

See “HECO and subsidiaries and service areas” above for a discussion of the nonexclusive franchises of HECO and subsidiaries. Most of the leases, easements and licenses for HECO’s, HELCO’s and MECO’s lines have been recorded.

See “Generation statistics” above and “Limited insurance” in HEI’s MD&A for a further discussion of some of the electric utility properties.

Bank

General.  ASB was granted a federal savings bank charter in January 1987. Prior to that time, ASB had operated since 1925 as the Hawaii division of American Savings & Loan Association of Salt Lake City, Utah. As of December 31, 2010, ASB was one of the largest financial institutions in the State of Hawaii based on total assets of $4.8 billion and deposits of $4.0 billion. In 2010, ASB’s revenues and net income amounted to approximately 11% and 51% of HEI’s consolidated revenues and net income, respectively, compared to approximately 12% and 26% in 2009 and approximately 11% and 20% in 2008, respectively.

At the time of HEI’s acquisition of ASB in 1988, HEI agreed with the OTS’ predecessor regulatory agency that ASB’s regulatory capital would be maintained at a level of at least 6% of ASB’s total liabilities, or at such greater amount as may be required from time to time by regulation. Under the agreement, HEI’s obligation to contribute additional capital to ensure that ASB would have the capital level required by the OTS was limited to a maximum aggregate amount of approximately $65.1 million. As of December 31, 2010, as a result of certain HEI contributions of capital to ASB, HEI’s maximum obligation to contribute additional capital has been

reduced to approximately $28.3 million. ASB is subject to OTS regulations on dividends and other distributions and ASB must receive a letter of non-objection from the OTS before it can declare and pay a dividend to HEI.

ASB’s earnings depend primarily on its net interest income—the difference between the interest income earned on earning assets (loans receivable and investment and mortgage-related securities) and the interest expense incurred on costing liabilities (deposit liabilities and other borrowings, including advances from the Federal Home Loan Bank (FHLB) of Seattle and securities sold under agreements to repurchase). Other factors affecting ASB’s operating results include its provision for loan losses, fee income, other noninterest income (including gains and losses on sales of loans, securities and notes and other-than-temporary impairments of securities) and noninterest expenses (including losses resulting from the early extinguishment of debt such as the loss resulting from a balance sheet restructuring in June 2008).

For additional information about ASB, see the sections under “Bank” in HEI’s MD&A, HEI’s “Quantitative and Qualitative Disclosures about Market Risk” and Note 4 to HEI’s Consolidated Financial Statements.

The following table sets forth selected data for ASB for the years indicated (average balances calculated using the average daily balances):

All of the foregoing ratios and returns for 2009 were adversely affected by ASB’s sale of its private-issue mortgage-related securities portfolio. All of the foregoing ratios and returns for 2008 were adversely affected by ASB’s restructuring of its balance sheet in June 2008.

ASB’s tangible efficiency ratio — the cost of earning $1 of revenue — decreased from 72% in 2009 to 56% in 2010, primarily due to losses related to the sale of the private-issue mortgage-related securities portfolio and other-than-temporary impairment (OTTI) charges on ASB’s securities portfolio in 2009 and lower noninterest expenses in 2010 due to the performance improvement project. The increase in tangible efficiency ratio for 2008 compared to 2009 was due to charges to noninterest income and noninterest expenses as a result of the restructuring of its balance sheet.

The following table shows for the periods indicated the effect on net interest income of (1) changes in interest rates (change in weighted-average interest rate multiplied by prior year average balance) and (2) changes in volume (change in average balance multiplied by prior period weighted-average interest rate). Any remaining change is allocated to the above two categories on a prorata basis.
