Solar energy in Massachusetts is facing an “unprecedented” attack from the Trump administration after the president approved landmark legislation this summer that killed two key tax credits, industry leaders told Gov. Maura Healey and her top climate deputy Monday.

Clean energy projects across the nation, most notably offshore wind, have faced headwinds under President Donald Trump, who has tried to stall major initiatives or block them entirely. Trump’s “One Big Beautiful Bill” took aim at the sector by rolling back clean energy tax credits.

Jessica Robertson, director of policy and business development for New Leaf Energy, said renewable energy is “under an unprecedented attack from the federal government.”

“But Massachusetts has an opportunity to accelerate the deployment of solar in the next five years in spite of those attacks,” Robertson said at a roundtable in Boston. “Massachusetts was an early leader in solar, but we ran into growing pains that brought the industry to a virtual standstill for several years.”

Tax incentives that have saved thousands of dollars for people in the U.S. looking to install home efficiency upgrades, clean energy installations like solar panels, or to purchase electric vehicles are set to expire at the end of this year.

The federal residential clean energy tax credit is slated to expire at the end of this year, and the clean energy investment tax credit is scheduled to end after 2027.

Healey said the tax credits have “helped make the electricity we need fast and affordable.”

“The (Trump) administration has slowed down permitting timelines and created other political roadblocks to energy development. They’ve imposed tariffs on materials that are needed for this industry and other industries, including gas turbines to transformers to steel, and this is going to contribute to delays and also to the raising of costs,” the first-term Democrat said.

Industry leaders said elected officials in Massachusetts should reform clean energy permitting to speed up solar projects.

Bronte Payne, senior manager for policy at Sunrun, a renewable energy company, said lawmakers should establish automated, instant permitting in cities and towns where projects are code-compliant and meet safety requirements.

“Automated permitting helps more solar and storage get installed faster and reduces the cost,” Payne told Healey and her deputies.

Healey signed legislation in November that she argued accelerated clean energy development by reforming siting and permitting processes.

The law established a 12-month deadline for municipal permitting for wind, solar, storage, and electric infrastructure. It also required municipalities to issue a single permit at the end of their process.

Robertson said there is no other state in the country where industry officials “can say that a project that we start permitting in 2026 can know that it will have a permit.”

“There is an increasing number of towns where solar and storage is effectively off limits. Your administration’s leadership has broken through this barrier to establish a new system with a standardized, data-driven approach to solar siting and much more predictability on timelines and outcomes,” Robertson said to Healey.

Nick d’Arbeloff, a senior member of the commercial team at ReVision Energy, said solar energy delivered 5,000 megawatts of energy, or $8.2 million in savings for ratepayers in Massachusetts, on June 24, the hottest day of the summer.

Massachusetts has about 5.8 gigawatts of installed solar, d’Arbeloff said.

“Supporting residential solar is essential for affordability, equity, and our broader clean energy goals,” he said.
