Elon Musk Floats Solar Overhaul Of Puerto Rico Power Grid, Governor Says 'Let's Talk'

With 90 percent of Puerto Rico still without power, Elon Musk has made hurricane-wrecked island an offer its governor couldn’t refuse.

The Tesla CEO tweeted Thursday that his company is capable of rebuilding Puerto Rico’s power grid, much of which was destroyed by Hurricane Maria , to run on solar power and batteries.

“The Tesla team has done this for many smaller islands around the world, but there is no scalability limit, so it can be done for Puerto Rico too,” the tech billionaire tweeted on Thursday.

However, Musk added, the vast project would require approval from the both the federal government and that of Puerto Rico, as well as commercial stakeholders. 

Musk floated the idea in response to a Twitter follower who suggested he take up the project.

But then Ricardo Rosselló, the governor of Puerto Rico, seemed intrigued by the offer and proposed the U.S. island territory could be Musk’s solar “flagship project.”

“Let’s talk,” Rosselló tweeted to Musk late Thursday . “Do you want to show the world the power and scalability of your #TeslaTechnologies?”

When Hurricane Maria made landfall in Puerto Rico on Sept. 20, it devastated much of the island , forcing thousands into shelters, destroying 80 percent of the value of the island’s agricultural industry and downing nearly all 2,400 miles of its power transmission lines.

But even before Maria, Puerto Rico’s power grid was fragile. The island’s only energy provider, Puerto Rico Electric Power Authority, was $9 billion in debt, and the grid suffered from constant power outages  due to poor maintenance, the Los Angeles Times reported.

The aging grid was especially susceptible to storms and unforeseen accidents. Last year, a fire at one of the island’s main power plants left millions in the dark . 

So Musk’s offer to turn Puerto Rico into one of his own solar projects may be a silver lining in the aftermath of Maria’s destruction. He’s been successful in this arena in the past, though on much smaller scales.

In November, the Tesla-owned SolarCity helped a 17-square-mile island in American Samoa that was reliant on diesel fuel become powered almost completely by solar energy .

The Environmental Protection Agency, Department of Interior and the American Samoa Power Authority funded the $8 million project to establish a 7-acre solar farm on the island. It is capable of storing energy in 60 Tesla Powerpacks (the company’s batteries) that can provide the island’s 600 residents with energy for up to three days without sun, according to National Geographic.

This year, Telsa finished a larger solar farm on the Hawaiian island of Kauai on 50 acres of land, with Powerpacks to store enough energy to service an estimated 4,500 homes .

Puerto Rico, which currently relies on imported oil to generate electricity, could benefit from a Musk-inspired takeover, but with 3,515 square miles and 3.4 million people, the island-wide project could be Tesla’s most ambitious project of its kind so far.
