Should the government be required to fulfill grant agreements made by a previous administration?
Federal judges in the District of Columbia and Rhode Island ruled that the EPA acted unlawfully when it terminated the $7 billion Solar For All program in August 2025. This decision may restore $181 million in promised funding to Arizona and the Hopi Tribe.
Why it matters
The ruling clarifies that already-awarded grant agreements constitute obligated funds that the government cannot unilaterally rescind following the passage of the One Big Beautiful Bill. For operators, this creates a precedent for securing contract performance even when subsequent legislation terminates an agency's broader mandate.
The EPA originally awarded nearly $7 billion in Solar For All grants in April 2024, of which only $71 million was disbursed before the program was terminated in August 2025. Arizona and the Hopi Tribe are now seeking the remainder of their $181 million allocation.
The players
Environmental Protection Agency
The federal regulatory body responsible for environmental oversight and the administration of national energy and infrastructure grant programs.
State of Arizona
A grant-seeking state entity that filed a lawsuit against the federal government to secure contested contract funds.
Hopi Tribe
A sovereign tribal nation that qualified for federal solar funding to address energy access gaps.
The details
The court found that the EPA lacked the authority to rescind grant agreements once they were legally obligated, despite the repeal of the underlying Greenhouse Gas Reduction Fund by the One Big Beautiful Bill in July 2025. While a federal judge previously dismissed Arizona's lawsuit in June 2026 for jurisdictional reasons, the new rulings suggest that these grant disputes fall under enforceable contract law rather than simple administrative repeal.
Timeline
April 2024: EPA awarded nearly $7 billion in solar grants.
July 2025: The One Big Beautiful Bill was signed into law.
August 2025: The EPA terminated the solar program.
September 2026: Federal judges ruled the EPA termination was unlawful.
August 8, 2027: The Court of Federal Claims will hold a trial for the Arizona lawsuit.
Market Landscape
This development follows the 2025 enactment of the One Big Beautiful Bill, which triggered widespread uncertainty by repealing the Greenhouse Gas Reduction Fund. The ruling marks a major departure from the EPA's position that the law granted it authority to automatically void existing grant agreements.
Operators currently holding or awaiting federal grant funds should consult with legal counsel to assess if their agreements are protected under the precedent established in these recent rulings. Monitor upcoming federal dockets for any EPA appeal filings that could impact the timeline for fund recovery.
The takeaway
The court's ruling establishes that grant contracts act as binding obligations, regardless of subsequent legislation. Business owners should document all awarded federal funding agreements as contractual assets to protect against future administrative shifts.
What happens next
The Court of Federal Claims is scheduled to hear the Arizona lawsuit on August 8, 2027.
