In Puerto Rico, Trump admin backs big battery project but snubs solar

The federal government just closed a nearly $490 million loan to help build two large battery storage systems in Puerto Rico, in the coastal cities of Arecibo and Santa Isabel. Together they'll total 220 megawatts and are meant to back up power for more than 100,000 customers during the outages that have plagued the island's grid since Hurricanes Irma and Maria. Batteries like these can step in when demand spikes or power plants fail, smoothing out the kind of surges and dips that damage equipment and cause blackouts.

The deal replaces an earlier Biden-era plan that paired batteries with a 70-megawatt solar project. Under the Trump administration, that solar piece was dropped, and the loan may now include support for a natural gas plant instead, though neither the developer nor the Energy Department has said what that would look like. This fits a broader pattern: the administration has pulled back funding for rooftop solar-plus-battery programs aimed at helping low-income and medically vulnerable households, redirecting money instead toward gas and fossil-fuel infrastructure.

None of this changes anything directly for homeowners outside Puerto Rico. But it matters for anyone there relying on solar-plus-battery setups for backup power, since federal support for those smaller residential systems is shrinking even as utility-scale battery projects — this one and others from companies like Tesla and Genera PR — move forward. Puerto Rico's grid remains unreliable, with outages last year running well above prior levels, and the mix of new batteries, gas plants, and reduced solar funding will shape how quickly that improves.
