Puerto Rico’s 70,000-home virtual power plant delivers 48 MW of real capacity, showing how rooftop solar and batteries can keep the grid stable and resilient during disasters.
Puerto Rico turned thousands of homes into one giant power plant. And it actually works!
More than 70,000 batteries are now working together to support the island’s grid. They deliver 48 MW of real capacity, which is enough to keep lights on and demand steady during peak hours.
This isn’t a pilot or a theoretical model. It’s a functioning virtual power plant (VPP) that proves distributed energy can deliver real resilience.
So, what made it work?
- ●The program built on what people already had: rooftop solar and batteries
- ●Payments go directly to homeowners, so there’s a clear financial reason to join
- ●It was designed with disaster recovery in mind, not just decarbonization targets
- ●It gained public trust because the grid had already failed, and people wanted control.
After Hurricane Maria, residents didn’t wait for help. They installed solar + storage to survive.
Now, those same systems are working together to prevent the next blackout. And now that it’s proven, more households are likely to join. Each new participant makes the VPP stronger, turning it into a more reliable, more defensible energy network.
This is what a people-led energy transition looks like. We might see this model leap from island to island.
Hurricane season will continue to be a stronger and more persistent threat, but with this kind of energy resilience, long waits to get back online could become a thing of the past. From the Caribbean to other vulnerable coastlines, this approach is poised to spread fast.
It’s distributed. It’s proven. And it’s built from the ground up.
Puerto Rico didn’t just install panels, they shifted control.
Are we ready to do the same in our backyards?
