Elon Musk says he can rebuild Puerto Rico's shattered power grid

Elon Musk is "full of crap" in claiming Tesla cars made today already have the hardware necessary for full autonomous driving, says General Motors' autonomous vehicle director.

The advantages of Tesla's Powerwall solution are that it can use stored solar energy during a power outage and could potentially reduce time-of-use rates by storing energy at night when rates are low. By way of solar power and batteries.

Tesla has already done similar battery and solar power projects with the Kauai Island Utility Cooperative in Hawaii and in American Samoa.

In response to a tweet asking whether he could rebuild Puerto Rico's electrical grid with solar, Musk said, basically, yes.

"Such a decision would be in the hands of the Puerto Rican Government, PUC, any commercial stakeholders and, most importantly, the people of PR".

Late Thursday, Puerto Rico Gov. Ricky Rossello expressed his interest, tweeting "Let's talk" to Musk, saying "PR could be that flagship project". 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.

Electric vehicle maker Tesla a year ago merged with another Musk startup, SolarCity.

A casual comment on Twitter by Tesla CEO Elon Musk about rebuilding Puerto Rico's power grid using solar technology is being treated seriously by the storm-ravaged island's top elected officials.

But Puerto Rico isn't a small island.

Tesla promised to build the South Australia facility in 100 days or else waive its fee, and that build-out so far appears to be going well.

In November 2016, SolarCity - a Tesla subsidiary - announced it had installed a solar power and microgrid on Ta'u that could power almost all of the island's needs.

Tesla has already shipped hundreds of its Powerwall battery systems to Puerto Rico and Tesla employees are now busy installing them and training locals how to continue the process. Last night, their governor, Ricardo Rossello, took to Twitter to take Mr. Musk up on that offer.
