Puerto Rico's fragile power grid was knocked offline after Hurricane Maria barreled through the US territory in late September, leaving millions of people without electricity. "That's why Tesla is now shipping Powerwalls, Tesla's home battery pack, in Puerto Rico since homeowners with existing rooftop solar installations that are still in place can connect to the battery packs instead of the grid and power their homes".
Musk said there's "no scalability limit" and Tesla could rebuild Puerto Rico's electrical system if the island's residents and government decided they want to pursue that option.
Tesla has already been lending a hand to Puerto Rico as it sent hundreds of its Powerwall battery systems that aid the use of solar panels. Saddled with debt and without the resources to tend to it, Puerto Rico's is even more burdened. Last year, 47 percent of Puerto Rico's electricity was generated by oil, compared with 0.3 percent of the United States as a whole. "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. Prior to the hurricane, the island territory of 3.4 million people had $73 billion in outstanding debt. When completed in December 2017 it is said it will be capable of powering up to 30,000 homes - if Musk fails on the challenge it will cost potentially the company over $50m.
Miller responded to Musk's announcement that all Tesla cars already have the hardware needed for fully autonomous driving.
Musk says that the second part of the reason for the delay is that Tesla will "increase battery production for Puerto Rico & other affected areas".
A microgrid array consisting of 5,328 solar panels powers Ta'u Island in American Samoa.
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.
