Ron & Steve Answer Your Questions

We appreciate the questions you’ve submitted through our various feedback channels. Since many of your inquiries have been focused on the impact this merger will have on Human Resources (HR) issues, we thought it would be helpful to provide you with an update from the HR integration team.

Currently, the team is conducting a thorough analysis of each company’s HR policies and programs, including core areas such as benefits, compensation and employee development. Considering the complexity and high level of detail behind these programs and policies, it will take some time to complete the review. The goal is for the team to have a comprehensive understanding of everything Exelon and Constellation currently offer our employees. As this information is gathered, the team also is assessing similarities and differences in approach along with the business rationale for why each program and policy was created.

The end result of this very intensive data analysis will form the basis for decision-making around recommended programs for our employees, and the components that will be important to include as we design an HR infrastructure that will best meet the needs of our employees and the combined company.

Note: the quotes below were featured on side bar next to main copy above

“We have a great opportunity and responsibility to help form our new company. How we position our HR strategy in compensation, benefits, development, diversity and inclusion, and recognition, for example, must ensure that we are able to attract and retain the best and brightest talent. For example, how we position our HR strategy in compensation, benefits, development, diversity and inclusion, and recognition must ensure that we are able to attract and retain the best and brightest talent.” —Amy Best, Exelon VP of Human Resources

“Throughout this highly detail-oriented process, both the Constellation and Exelon teams have come together with a willingness to share and discuss the rationale for existing programs and policies. In my opinion, this has been a very good learning experience that will provide a sound foundation as we move into the design phase, which will focus on the programs and policies after the transaction has been closed.” —Tom Ruszin, Constellation VP of Human Resources

With more than 100 years of service to the Greater Philadelphia region, PECO has a long history and culture of excellence.

One of the oldest and largest utility companies in the U.S., PECO has its origins in the work of Thomas Edison. As innovation brought new conveniences, population growth and industry development, PECO grew to meet the increasing demand of its customers.

PECO’s stewardship helps customers make better choices about energy usage and the company is focused on setting a strong example as a good corporate citizen and environmental leader.

Rules of the Road

While Exelon and Constellation work to obtain necessary regulatory approvals and to close the transaction, the companies must operate as entirely separate businesses. Employees must treat one another as competitors in our day-to-day work. This means we cannot directly exchange competitively sensitive information, and must be careful not to do anything that lessens competition between the companies or that would lessen either entity’s ability to compete were the transaction not to close. This is an important and sometimes complicated topic. If you have any questions, please discuss with your supervisor or legal counsel before action is taken.

Exelon

• 25,619 MW total owned generation

• 17,047 MW nuclear with 17 reactors in Illinois, Pennsylvania and New Jersey

• 105 fossil, landfill gas and hydro units; 36 wind projects and solar plants produce more than 8,571 MW in 11 states

Constellation Energy

• 11,430 MW total owned generation

• 1,921 MW nuclear with 5 reactors in Maryland and New York held in a joint venture with EDF

• 60 MW solar generation installed and under development

• 70 MW wind generation

• Fossil, renewable assets

Combined Entity

34,401 MW across all fuel sources (net of expected divestitures), including:

• 18,967 MW of clean nuclear energy in 22 units in Illinois, Pennsylvania, Maryland, New Jersey and New York

• 15,433 of diverse generation, including (in order of MW) natural gas, coal, hydro, oil, wind and solar

Environmental stewardship—a shared goal

In the last issue of IN, Ron and Steve mentioned a number of areas where the companies have similar approaches or processes. One additional area of common interest is environmental stewardship. Here, we’ll provide a brief overview of the companies’ efforts in this critical area, and we encourage you to learn more by following the links in this article.

Exelon 2020—a roadmap to a lower-carbon future

In July 2008, Exelon launched an ambitious plan, unique in the electricity industry, to shrink its carbon footprint. Exelon 2020: a low-carbon roadmap is a comprehensive package of initiatives to reduce, offset or displace more than 15 million metric tons of greenhouse gas (GHG) emissions per year by 2020—an amount roughly equal to Exelon’s total emissions in 2001, the first full year of the company’s operation after the merger of Unicom and PECO. Reducing emissions by this amount is equivalent to removing about 3 million cars from our roads annually.

Exelon 2020 is predicated on a comprehensive economic analysis of GHG abatement options available to Exelon, and it is updated on an annual basis to reflect economic, regulatory and industry trends and realities. By adapting to changing market conditions, Exelon 2020 synthesizes Exelon’s core business strategy of being clean in competitive markets and is not simply an effort to “go green.”

Most importantly, Exelon believes that pursuing the cheapest options offers the greatest benefits to customers, shareholders and the economy. For example, customer energy efficiency is a significantly less expensive way of reducing emissions than building a new nuclear plant, and increasing the output of existing nuclear facilities is more affordable than building new solar or wind. By practicing what it has been preaching—based on economics and not based on what is politically popular—Exelon has achieved over half of its Exelon 2020 goal.

Exelon is proud to have been named to the Dow Jones Sustainability Index for the past five years and to have been included on the Carbon Disclosure Project Leadership Index five of the past six years.

You can read the three published reports on Exelon 2020 by visiting the Exelon 2020 section of the Exelon website. The next Exelon 2020 report, including a new economic analysis and progress update, is expected in the fourth quarter of 2011.

Constellation—empowering its businesses and customers to use energy wisely

Constellation has a long track record of responsible environmental stewardship, culminating in 2010 with the implementation of a company-wide environmental management system (EMS) and the launch of its first-ever corporate environmental sustainability goals.

The company’s report card to date has been impressive. The Dow Jones Sustainability Index, which tracks the financial performance of leading sustainability-driven companies, recognized improved performance and reporting practices by including the company in its North America Index once again. Constellation’s businesses are working hard to achieve its goals. For example, 36 megawatts of customer-sited photovoltaic systems were sold last year to complement its energy efficiency business; and Constellation’s three jointly owned nuclear facilities—Calvert Cliffs, Ginna and Nine Mile Point—along with BGE’s gas distribution operations are now ISO 14001 certified.

Helping its customers manage their energy use has also been a high priority for Constellation. Last year, its commercial and industrial customers were introduced to VirtuWatt, an innovative energy-management product, which allows customers to develop energy management scenarios and respond in real-time to changes in market demand and prices for electricity. On the BGE side, customers will soon have the ability to manage their energy use through its investment in smart grid technology.

Constellation also continues to invest in cleaner generation. The company recently invested nearly $1 billion in efficient natural gas assets, primarily 4,300 MW in facilities in the Boston area and Texas, as well tens of millions of dollars in its newly constructed Criterion Wind Farm in western Maryland.

New Baltimore Headquarters Evaluation

The process to gather information on available commercial space for the combined company’s competitive energy and renewables development businesses in downtown Baltimore has begun. A request for information was issued by our commercial real estate services firm to obtain general specifications of available locations from local commercial developers and brokers.

“It’s early in the process and we’re working hard to make sure we gather all of the right information, local input and community support for what we intend to be a LEED-certified space for our new Baltimore headquarters,” said Deb Kuo, director of real estate services for Exelon.

The combined company plans to build or renovate a “green” building in Baltimore. The request for information seeks data on size, current condition and space availability of potential sites and existing buildings in Baltimore. Specifications on parking, recent upgrades and renovations on electrical, heating and air conditioning systems, lease terms, building amenities and any green building status are also being considered. With a requirement of 300,000 to 375,000 square feet, the request is one of the largest in the market.
