Elon musk tweeted on Thursday that Tesla can help Puerto Rico with a long-term solution in getting the island's lights back on, by rebuilding Puerto Rico's electrical grid which was devastated by the recent hurricanes, specifically hurricane Maria, which struck on Sept. 20.

He tweeted that "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. Such a decision would be in the hands of the PR govt, PUC, any commercial stakeholders and, most importantly, the people of PR. "

The tweet came after Scott Stapf of consulting firm The Hastings Group questioned in Twitter whether Musk has the capability of rebuilding the island's power infrastructure using independent solar and battery systems.

Puerto Rican Governor Ricardo Rossello has said that he's open to the discussion of making Puerto Rico Tesla's energy "flagship project."

Right now, two weeks after the storm caused devastation on the island, only less than 10% of the people in Puerto Rico have the lights back on.

Previously Musk has promised to solve Australia's power problems in 100 days, the challenge that started just a week ago. In case of the Aussie power grid problem, he said that if he doesn't get it done in 100 days, it's gonna be free, which could be up to $50 million from his own pocket.
