Developers will have four calendar years to place the facility into service after construction officially commences. Any developers needing an extension for construction lasting beyond four years will have to demonstrate "continuous construction" as opposed to merely demonstrating. . This Notice provides guidance regarding when construction of a wind facility or solar facility has begun for purposes of determining whether such facility is subject to the credit termination provisions added to Sections 45Y and 48E by the OBBBA. For a deeper dive into these implications, more. . Additionally, taxpayers who wish to claim a wind or solar ITC or PTC that avoids the new December 31, 2027, placed-in-service date requirement must begin construction by performing on-site or off-site physical work before July 4, 2026. Notice 2025-42 is effective for wind and solar projects that. . The IRS on Aug. If construction begins before this date, the project may qualify under the four-year continuity safe harbor. 5 MW AC Nameplate Capacity) Must use the Physical Work Test to demonstrate construction has. . The changes made by the One Big Beautiful Bill Act (OBBBA) leave only a short window for solar and wind projects to be eligible for clean electricity tax credits under Sections 45Y and 48E, requiring either that they start construction by July 4, 2026, or are placed in service by December 31, 2027.
