Nearly 200 organizations are urging the Trump administration and Puerto Rico’s governor to restore $350 million in federal funding that was meant to finance the installation of rooftop solar and battery systems for 12,000 low-income families across the U.S. territory.

Many of the families have disabilities or medical conditions that require electricity. Concern is growing that the U.S. will abandon them as chronic power outages persist and the Atlantic hurricane season officially nears — it runs from June 1-Nov. 30.

“For them in particular, whether they get a (solar) system or not is something that is really life or death,” Charlotte Gossett Navarro, Puerto Rico chief director for the Hispanic Federation, said in a phone interview.
