Judge Orders EPA to Reinstate $7B Solar for All Programme

#

A federal judge has ordered the Environmental Protection Agency to restore a $7 billion clean-energy programme it cancelled last year, ruling that the termination broke federal administrative law. In a decision handed down on 18 September 2026, the court found that the EPA acted without legal authority when it axed the Solar for All programme, vacated the cancellation, and effectively put the money back in play.

The stakes had been building for over a year. Solar for All had sat suspended since the EPA scrapped it in the summer of 2025, even though the grant funds were already legally committed to states and community organisations before the agency moved to cancel them. This ruling is a direct judicial rebuke to a concrete executive branch decision, not a hypothetical policy skirmish.

Here is what you need to understand about the ruling and what remains unsettled. This piece covers the court’s precise legal reasoning, the competing interpretations of the One Big Beautiful Bill Act that decided the case, what reinstatement means for the more than 900,000 lower-income Americans the programme was built to serve, and why the outcome is far from final despite the order.

Federal judge finds EPA exceeded its authority in cancelling Solar for All

Judge Mary McElroy of the U.S. District Court for the District of Rhode Island issued the ruling on 18 September 2026, granting summary judgment to the plaintiffs and declaring the EPA’s termination unlawful under the Administrative Procedure Act (APA). This was not a narrow procedural finding. It was a determination that the agency acted outside the limits Congress placed on it.

“the termination of the Solar for All program is declared unlawful under the APA and is ordered vacated.”

The distinction matters. McElroy did not rest the decision on the usual “arbitrary and capricious” standard, which asks whether an agency reasoned its way properly to a defensible conclusion. She grounded it in APA section 706, the provision that bars agency actions taken “contrary to law” or “in excess of statutory authority.”

“When an agency acts outside the bounds of its statutory authority, it violates the [Administrative Procedure Act]… The termination decision was therefore contrary to law and in excess of its statutory authority, in violation of the APA.”

The practical effect of that framing is that the court found the EPA had no legal power to cancel grants Congress had already directed it to administer. According to the court’s reasoning, congressional intent required the agency to keep running the previously committed Solar for All grants, not to unwind them.

For anyone following the durability of this decision, the legal basis is the whole story. A finding that an agency merely got the process wrong can often be cured by redoing the process. A finding that an agency acted without authority in the first place is far harder to walk back, and it shapes exactly what grounds an appeal would have to overcome. The EPA did not provide an immediate response to requests for comment following the ruling.

The legal dispute at the heart of the case: what OBBBA actually repealed

The case turned on a single question: what did the One Big Beautiful Bill Act (OBBBA) actually do to the money behind Solar for All? Both sides agreed the law repealed the Greenhouse Gas Reduction Fund that funded the programme. They disagreed sharply on what that repeal reached.

Congressional appropriation authority over federal clean-energy programmes has been tested repeatedly since 2025, with the government shutdown episode revealing how legislative funding decisions interact with executive discretion over programme administration and obligation timelines.

The EPA’s reading

The agency’s position, advanced under EPA Administrator Lee Zeldin, was that once OBBBA became law on 4 July 2025, the repeal stripped the EPA of the statutory authority to administer Solar for All at all. On that view, cancelling the grants roughly one month later was not a policy choice the agency made; it was a legal consequence it had no way to avoid. Reuters reported that the agency treated previously awarded grants as revocable once the underlying fund was gone.

The court’s reading

McElroy rejected that interpretation directly. The grant funds had been fully obligated ahead of a September 2024 deadline, with a five-year availability period, meaning the money was locked to specific grantees well before OBBBA existed. The court found that the repeal rescinded only unobligated fund balances, leaving already-committed awards untouched.

“The OBBBA did not convert SFA funding into a lump-sum amount subject to EPA’s discretion.”

That single line carries the case. McElroy held that “already existing grant awards were to remain in place, subject to the residual statutory authority under which they were originally obligated,” and that Congress’s clear intent was for the EPA to continue administering the committed Solar for All grants.

The line between “obligated” and “unobligated” money is not accounting trivia. It is the exact boundary that decided whether the EPA had any authority to cancel these specific grants, and the court drew it firmly against the agency. That is worth understanding closely, because it is precisely the interpretation an appellate court would revisit. The strength of the reinstatement rests entirely on whether a higher court agrees that a repeal of future funding cannot reach money already committed.

The 900,000 Americans left waiting while the legal dispute played out

Behind the statutory argument were the households the programme was built for. Solar for All was designed to expand residential and community solar access for lower-income Americans and to cut electricity bills for more than 900,000 lower-income Americans across the country.

Solar energy investment in lower-income and community-scale segments depends heavily on federal grant programmes like Solar for All, because private capital alone has historically underserved the residential market segments the programme was designed to reach.

The lawsuit that forced the issue was brought by four legal organisations on behalf of several community and labour groups. The plaintiff structure grounds the abstract programme in specific people and institutions.

• Legal groups: Conservation Law Foundation, Southern Environmental Law Center, Lawyers for Good Government, and Lawyers Committee for Rhode Island
• Represented organisations: Rhode Island AFL-CIO, Rhode Island Center for Justice, Solar United Neighbors, and others

Rhode Island’s own award shows what the ruling restored in concrete terms.

Jillian Blanchard, Senior Vice President of Climate Change and Environmental Justice at Lawyers for Good Government, framed the human cost of the delay.

Billions of dollars intended to reduce electricity costs had remained out of reach for these communities for more than a year before the September 2026 ruling, Blanchard said, and the court has now confirmed the EPA’s cancellation was unlawful.

That gap is the part the ruling cannot erase. The more than a year between cancellation and reinstatement was real time during which promised bill reductions did not reach households that had been told to expect them. The legal order restores the footing; it does not refund the delay.

What the reinstatement order does not resolve

The ruling is significant, but reinstatement and full programme operation are not the same thing. Three things stand between this decision and money actually flowing to communities, and each could shift the outcome.

1. Whether the EPA files a formal notice of appeal. An appeal has been described as “pending” in reporting by Reslink on 19 September 2026, but no formal notice of appeal has been confirmed in accessible sources as of 21 September 2026. Until that is clear, the agency’s next move is an open question.

Smart Cities Dive reporting on the EPA’s response confirmed the agency was reviewing the decision and considering options for appeal, based on a direct agency email, as of 21 September 2026.

1. Whether the EPA begins concrete compliance steps. Even with the termination vacated, the agency has to re-execute grant agreements and publish an implementation schedule for the money to move. None of those steps have been reported as of this date, and an agency contesting a ruling on appeal has little incentive to rush implementation.
2. How an appellate court rules on the OBBBA statutory-authority question. A higher court could adopt a broader reading of the repeal and potentially re-empower the EPA to cancel or restructure the grants. American Quorum, writing on 19 September 2026, characterised the decision as restoring legal footing “while leaving open the possibility of an appeal.”

That leaves grantees and communities in an awkward middle. The programme is legally alive again, but the appellate risk is live, and a reversal on the same statutory question the district court decided would undo the reinstatement.

For anyone tracking clean-energy investment or federal funding disputes, the practical read is straightforward: the question is no longer whether the court ruled, but whether the EPA complies and whether an appellate court upholds the finding. The ruling opens a path. Where it leads depends heavily on the next 60 to 90 days.

A ruling that redraws the line between congressional appropriation and executive cancellation

Strip away the programme mechanics and a governing principle sits underneath the decision. Once Congress has appropriated funds and an agency has validly obligated them through executed grant awards, the executive branch cannot unilaterally cancel those obligations by pointing to a later statutory repeal that reached only unobligated balances.

That is why the “obligated” versus “unobligated” distinction did so much work here. The ruling positions itself as a judicial constraint on the administration’s efforts to use OBBBA to unwind commitments funded under the Inflation Reduction Act, at least in this instance.

The New York Climate Superfund ruling, handed down within days of the Solar for All decision, adds a second judicial front to the broader pattern of courts drawing hard limits around executive and legislative authority over climate-related funding commitments.

What this tells you about the limits of executive power is concrete: repealing a funding stream does not automatically extinguish legal obligations already created under it. If that principle survives appeal, it narrows how future administrations can approach similar rollbacks.

Executive authority over energy programmes has expanded and contracted sharply across multiple policy domains in 2026, with the Defense Production Act invocations for pipeline infrastructure representing a parallel case where the administration asserted broad statutory powers that courts have been asked to scrutinise.

The two variables that will decide the ruling’s lasting weight are the same ones that decide the programme’s fate. Whether the EPA appeals, and what an appellate court concludes about the statutory-authority question, will determine whether 18 September 2026 marks a durable precedent or a temporary reprieve.
