An expanded investment tax credit (ITC) for clean energy generation and storage. The ITC would revert to 30% for solar energy and certain other energy projects (geothermal energy, qualified fuel cell, geothermal heat pump, small wind, offshore wind, waste energy recovery, and combined heat and power property) that begin construction in 2022 through 2026, and would be expanded to include certain standalone storage technology beginning in 2022. The ITC rate would phase out over five years beginning in 2027 (reduced 20% each year), reaching zero for projects commencing construction after 2030, apparently eliminating the permanent residual 10% ITC for solar and geothermal energy projects under current law.
