Puerto Ricans power their own solar boom

 From Canary Media

A bright yellow building with bold green trim hums with activity in Caguas, a city sprawled across a mountain valley south of San Juan, Puerto Rico. In a spacious kitchen, volunteers chop vegetables and cook rice for community meals. Down the hall, visitors browse racks of free and discounted produce, canned beans and bottles of oil. Outside, beneath a large metal awning, retirees soak in calming music as they take part in a stress-relief workshop.

The community services on offer here at the Centro de Apoyo Mutuo, or Mutual Support Center, are made possible by the 24 solar panels mounted on the rooftop. Two lithium-ion batteries the size of suitcases are kept in a windowless storage room, allowing the center to stay open on cloudy days and in the evenings. The building doesn’t use any electricity from the utility grid.

Nearly five years ago, after Hurricane Maria tore a path of devastation across the U.S. territory and all but destroyed Puerto Rico’s electricity system, residents in Caguas reclaimed what had for decades been an abandoned Social Security office. They ripped out moldy carpet, scrubbed the walls and began providing food and supplies to neighbors.

“This was a space that wasn’t serving the people, and now the community has taken it over,” Marisel Robles, one of the center’s organizers, says on a muggy day in early May, just weeks before the start of the next Atlantic hurricane season.

Robles guides me up a thin metal ladder to the rooftop of the one-story building, pushing aside tree branches sagging with brown seed pods. Saúl González, a volunteer and local solar installer, joins our expedition. The three rows of solar panels form a ​“mosaic” of different makes and models, all of them donated by nonprofit organizations, he explains.

With 6 kilowatts of solar capacity and 30 kilowatt-hours of battery storage, the system can typically meet the center’s power needs. Occasionally, members cut the lights and fans during the day to save electricity for an evening dance class. Still, Robles says it’s better than running expensive, polluting diesel generators or depending on the island’s electric grid — which, despite years of post-hurricane repairs, remains prone to routine outages, sweeping blackouts and frequent voltage surges that fry people’s appliances. In early April, the entire island lost grid power for three days after an aging electric breaker caught fire on the southern coast.

“Sometimes, we hear the ​‘boom’ of people turning on their diesel generators, and that’s how we know the power went out in town, because here we still have power,” Robles says, looking out over the tops of neighboring buildings. ​“For us, it’s like a victory every day this happens, because we feel like we did something right.”

The Mutual Support Center is not unique in its ability to produce its own clean energy. A rising number of Puerto Ricans are installing solar panels and batteries on their homes and businesses, fed up with the unstable electric grid, high electricity bills and the state-owned utility’s reliance on fossil fuels. As of January 2022, some 42,000 rooftop solar systems were enrolled in the island’s net-metering program — more than eight times the number at the end of 2016, the year before Hurricane Maria struck the island, according to utility data. Thousands more systems are operating but are not officially counted because, like the center’s unit, they aren’t connected to the grid.

Spearheaded largely by residents, business owners and philanthropies, the grassroots solar movement sweeping the island is happening despite headwinds from the territory’s centralized utility — which claims it’s working to advance the island’s clean energy goals but continues investing in fossil fuels. Solar proponents say that, for the technology to reach most of Puerto Rico’s 3.2 million people, the government and its utility will need to more fully participate in what has largely been a bottom-up energy transformation. With billions of federal recovery dollars set to flow to Puerto Rico, they argue that now is the time for public policies and investments that shift the island away from an outdated model of large, far-flung power plants to one that supplies clean electricity close to where people need it.
