Musk said that Tesla has done this for many small islands around the world and there is no scalability limit.
The idea could come to fruition.
Governor Rossello tweeted at Musk shortly after with, "Let's talk".
Tesla is among the USA companies sending rooftop panels and batteries to Puerto Rico, where more than 90 percent of homes and businesses remain without electricity after Hurricane Maria destroyed the grid.
Tesla, however, has sent hundreds of its Powerwall batteries, which collect and store solar energy, to help provide power more immediately to Puerto Ricans.
This isn't the first time Musk has proposed launching a major innovative infrastructural project on Twitter. It has a population of 3.4 million people, and its power generation was 20 billion megawatt-hours in 2014. "PR could be that flagship project", Puerto Rico Electric Power Authority is a huge problem Not only is the island's electrical grid decimated, but the Puerto Rico Electric Power Authority is in a fiscal mess. Some in Puerto Rico may be in the dark for months as the grid is repaired.
Tesla has already implemented systemwide solar and battery projects on islands like Kauai in Hawaii and another American Samoa. "Hopefully, Tesla can be helpful". Tesla quickly started quietly shipping Powerwalls there to try to get power back on to some houses with solar arrays. In tweets that followed, Musk and Rossello agreed to talk more in detail about this on Friday. "Diverting resources to fix Model 3 bottlenecks & increase battery production for Puerto Rico & other affected areas".
The Governor Ricardo Rosselló said on Monday that it could take one month to restore power to only a quarter of households in the island.
