Seven Federal Bills Would Restore the Clean Energy Credits, and Every One of Them Expires on January 3

At least seven federal bills filed since the One Big Beautiful Bill was signed would restore some or all of the Inflation Reduction Act clean energy credits it cut. Every one of them dies when the 119th Congress ends on January 3, 2027, and would have to be refiled from scratch in the next session. pv magazine USA catalogued the set on November 6.

The bills. Three are identified by name. H.R. 7977, the Energy Bills Relief Act, is the broadest: it would strip the foreign entity of concern (FEOC) restrictions, reinstate grant funding and add a transmission tax credit. H.R. 8477, filed by a Republican, would restore the tax credits while leaving the electric vehicle and manufacturing credits out. S. 4175, from Senator Ron Wyden, would tie the life of the clean electricity credits to the trajectory of retail electricity prices. The balance of the seven is described in aggregate as legislation restoring some or all of the credits.

What the seven share is not substance but a calendar. The refiling reset applies uniformly. Any relief that reaches storage projects through legislation therefore arrives on a 2027 clock at the earliest, and only after a new vehicle is introduced, referred and moved in a Congress that has not yet convened.

The material assistance rule. For battery storage, the federal provision that governs project economics is not a headline credit rate but the material assistance cost ratio sitting underneath Section 48E. A project that begins construction in 2026 holds a 55 percent threshold under IRS Notice 2026-15, the interim guidance issued to address material assistance for sections 45Y, 48E and 45X while deferring on broader prohibited foreign entity status questions.

The threshold attaches to the construction start rather than to the filing year. That is the structural feature worth noting: a 2026 start carries its own compliance standard forward, and later legislative movement does not retroactively loosen or tighten it. Projects beginning construction in 2026 stay at 55 percent regardless of what passes afterward.

Of the three bills identified by name, only H.R. 7977 touches FEOC at all. The other two address credit restoration and credit duration. A developer underwriting a storage project against the material assistance ratio is therefore watching one legislative vehicle out of three named, and that vehicle expires with the rest.

The December date. Treasury material assistance safe harbor tables are due December 31. That administrative deliverable sets the documentation standard against which 2027 storage procurement will be measured, and it lands three days before the seven bills expire. The sequencing is worth tracking: the agency deadline arrives first, and it arrives on a timetable that does not depend on Congress reconvening.

The Wyden trigger. S. 4175 would run the clean electricity credits until the later of 2032 or six years after a year in which the national average retail electricity price rises more than 2 percent. The drafting indexes the life of a federal credit to the same bill escalation that drives the commercial demand charge savings case.

Whether that construction functions as a long extension depends on the path of retail rates, which the bill does not forecast. One data point from the current rate environment: Arizona Public Service bills have risen about 52 percent over five years, with the utility seeking a further 14 percent residential increase and 45 percent or more for data centers in a case due for decision in December. That is a single service territory rather than a national average, and the national figure the Wyden language turns on is not established here. The mechanism, not the outcome, is the part that is settled.

The Ford and DESRI deal. D. E. Shaw Renewable Investments and Ford Energy announced a partnership on November 4 to deploy US-assembled battery storage. Ford Energy’s DC block is a 20-foot containerised system built around 512Ah LFP cells in two-hour and four-hour configurations, assembled at Ford’s Kentucky gigafactory with 20 GWh of annual capacity. Full US assembly for FEOC and prohibited foreign entity compliance is stated as the selling point. First deliveries arrive in late 2027.

The cell sits in the 500-plus Ah category while CATL, EVE, REPT, Hithium and CALB ship 587 to 628Ah cells at roughly 6.25 MWh per container. Ford’s line joins Samsung SDI’s Indiana prismatic LFP capacity, LG’s Holland plant and the Ultium Spring Hill conversion in the domestic compliant supply pool. Tariffs of about 58 percent apply to Chinese storage cells, with Section 45X credits running alongside them.

The juxtaposition is direct. Ford Energy is selling FEOC compliance as a product attribute on deliveries beginning in late 2027. H.R. 7977 would remove the restriction that gives that attribute its commercial force, and H.R. 7977 expires on January 3.

The vehicle. Roth Capital’s Philip Shen quoted a contact in the Republican party in late September saying that “we are moving into a positive political environment for solar.” Sentiment of that kind describes appetite rather than scheduling. Credit changes of this scale have historically traveled attached to larger legislative packages, on timetables their sponsors do not control, and none of the seven bills has cleared its chamber.

The position through 2027. For a commercial storage project, the operative facts are narrow and currently fixed. A 2026 construction start locks the 55 percent material assistance threshold under Notice 2026-15. Treasury safe harbor tables are due December 31 and will set the documentation standard for the following procurement year. Every legislative route to FEOC relief resets in January and must be refiled.

Developers weighing whether to wait for Congress are weighing a known administrative deadline in December against seven bills with a shared expiry date in the first week of January. The administrative track is the one with a date on it.
