IRC §48E Clean Electricity Investment Credit and IRC §45Y Clean Electricity Production Credit

Applicable to facilities for which construction begins after July 4, 2026, the credits are repealed for wind and solar technology for facilities placed in service after 2027. This means the post-2027 repeal date does not apply if the construction of the facility begins no later than July 4, 2026. However, the early termination does not apply to energy storage technology for purposes of the IRC 48E Investment Credit.

In addition, OBBBA tightens restrictions regarding sourcing supplies from foreign entities of concern for facilities that begin construction after December 31, 2025. Finally, the credit is no longer available to taxpayers who lease the property to a third-party, applicable to taxable years beginning after July 4, 2025 (date of OBBBA’s enactment) (OBBBA §§70512, 70513; IRC §§45Y, 48E)
