New Law Will Extended, Expand and Increase Federal Clean Energy Investment Tax Credit to New Technologies, Fuels, and Energy Users

Capstone Green Energy Corporation (NASDAQ: CGRN) praises the extension, expansion and increases of the federal Investment Tax Credit (ITC) and Production Tax Credit (PTC) for clean energy technologies in the Inflation Reduction Act recently signed into law by President Biden, which Capstone believes will directly benefit the company and its customers. The legislation increases the tax credit available to microturbine combined heat and power (CHP) projects from 10% to 30% for projects that are placed in service or safe harbored by the end of 2024, and it reinstates the tax credit for biogas energy projects. A bonus credit of 10% is available for projects that meet domestic content requirements or are in energy communities. It also adds new covered technologies, including energy storage, microgrid controllers, and hydrogen production facilities. Capstone's expanded business strategy includes many of these new technologies like energy storage, microgrid controllers, and hydrogen. Capstone microturbines are produced in the U.S. at our Van Nuys, CA manufacturing facility.

This groundbreaking climate policy will support the transition to zero emissions CHP while encouraging domestic manufacturing and the revitalization of communities currently reliant on fossil energy plants and jobs. Starting in 2025, the structure of the energy tax credit changes to a technology-neutral credit for zero-emissions facilities, which can be elected as either an ITC or a PTC. Stretching the availability of the technology-neutral credits through 2035 or sooner if electric sector greenhouse gas emissions reduction targets are met provides certainty for longer-term development than past short-term extensions. New labor requirements for prevailing wage and employment of apprentices will be developed by the IRS and applied to ITC and PTC taxpayers, but projects under 1 MW or projects that start construction before 60 days after this guidance is issued will be exempt.

Tax-exempt entities like non-profit hospitals and municipal entities will also be able to take advantage of these tax credits through the direct pay and transferability options but must meet domestic content requirements. New credits were also added for hydrogen production determined by kilograms of clean hydrogen produced per year and advanced energy manufacturing, which may be used, for example, to re-equip an industrial facility in a way that reduced greenhouse gas emissions by 20% or more.
