Close to 90 percent. That’s roughly how much of Puerto Rico is still without power three weeks after Hurricane Maria slammed into the island.

It’s a major crisis for the US territory, but perhaps an opportunity as well — for the island to start building a more resilient and cleaner power system.

“Even before the storm, the infrastructure was in bad shape,” says Jessica Leigh Hester of The Atlantic's CityLab. “The vast majority [of the island’s power] was supplied by a single utility that leaned heavily on diesel. Customers were already paying close to the highest [rates] in the country, and the company was tremendously in debt and filed for bankruptcy in July.

“The question of how to get the whole island back up and running is also one about what the future of energy and resiliency on the island can look like,” Hester adds.

And into that breach are stepping solar power companies, like Tesla in the US and Germany’s Sonnen.

Hester says companies like Sonnen, which makes batteries that store solar energy, are offering to help build “micro-grids” — small-scale, closed-loop energy systems — that could initially support things like health clinics and cooling centers for storm victims and slowly grow to greater capacity.

Tesla, meanwhile, issending hundreds of its solar batteries to Puerto Rico and discussing a bigger engagement with the island’s governor, Ricardo Rossello.

Great initial conversation with @elonmusk tonight. Teams are now talking; exploring opportunities. Next steps soon to follow.

But of course, Hester says, it’s not just about helping after a crisis.

“This humanitarian intervention’s likely to be partnered with a business end goal. ... It’s an opportunity to help, but also an opportunity to grow the renewables industry there.”

And Hester adds that many people say such efforts are badly needed.

“Many of the sources that I’ve been speaking with, from former EPA officials to humanitarian officials, are saying that they feel it’s irresponsible to just build the infrastructure back up to the condition it was in before the disaster, because ... fixing a broken system, they told me, is not really a fix at all.”
