A major solar energy trade group now says the Trump administration is refusing to do even routine work to permit solar projects on private lands — and that the situation has become so dire for the industry, lawmakers discussing permitting reform in Congress should intervene.

The Solar Energy Industries Association on Thursday published a letter it sent to top congressional leaders of both parties asserting that a July memo from Interior Secretary Doug Burgum mandating “elevated” review for renewables project decisions instead resulted in “a nearly complete moratorium on permitting for any project in which the Department of Interior may play a role, on both federal and private land, no matter how minor.” The letter was signed by more than 140 solar companies, including large players EDF Power Solutions, RES, and VDE Americas.

The letter reinforces a theme underlying much of Heatmap’s coverage since the memo’s release — that the bureaucratic freeze against solar decision-making has stretched far beyond final permits to processes once considered ancillary. It also confirms that the enhanced review has jammed up offices outside Burgum’s purview, such as the Army Corps of Engineers, which oversees wetlands, water crossings, and tree removals, and requires Interior to sign off on actions through the interagency consultation process.

SEIA’s letter asserts that the impacts of Burgum’s memo stretch even to projects on private lands seeking Interior’s assistance to determine whether federally protected species are even present — meaning that regardless of whether endangered animals or flowers are there, companies are now taking on an outsized legal risk by moving forward with any kind of development.

After listing out these impacts in its letter, SEIA asked Congress to pressure Interior into revoking the July memo in its entirety. The trade group added there may be things Interior could do besides revoking the memo that would amount to “reasonable steps” in the “short-term to prevent unnecessary delays in energy development that is currently poised to help meet the growing energy demands of AI and other industries.” SEIA did not elaborate on what those actions would look like in its letter.

“Businesses need certainty in order to continue making investments in the United States to build out much-needed energy projects,” SEIA’s letter reads. “Certainty must include a review process that does not discriminate by energy source.” It concludes: “We urge Congress to keep fairness and certainty at the center of permitting negotiations.”

Notably, the letter arrived after American Clean Power — another major trade group representing renewable energy companies — backed a major GOP-authored permitting bill called the SPEED Act that is moving through the House. Although the bill has some bipartisan support from the most moderate wing of the House Democratic caucus, it has yet to win support from Democrats involved in bipartisan permitting talks, including Representative Scott Peters, who told me he’d back the bill only if Trump were prevented from stalling federal decision-making for renewable energy projects.

SEIA has deliberately set itself apart from ACP in this regard, telling me last week that it was neutral on the legislation as it stands. In a statement released with the letter to Congress, the trade group’s CEO, Abigail Ross Hopper, said that while “the solar industry values the continued bipartisan engagement on permitting reform, the SPEED Act, as passed out of committee, falls short of addressing this core problem: the ongoing permitting moratorium.”

“To be clear, there is no question we need permitting reform,” Hopper stated. “There is an agreement to be reached, and SEIA and our 1,200 member companies will continue our months-long effort to advocate for a deal that ensures equal treatment of all energy sources, because the current status of this blockade is unsustainable.”

In a statement to Heatmap News, Interior spokesperson Alyse Sharpe confirmed the agency is using its “current review process” on “federal resources, permits or consultations” related to solar projects on “federal, state or private lands.” “This policy strengthens accountability, prevents misuse of taxpayer-funded subsidies and upholds our commitment to restoring balance in energy development.” The agency declined to comment on SEIA’s request to Congress, though. “We don’t provide comment on correspondence to Congress regarding Interior issues via the media,” Sharpe said.
