Tesla is stepping in to aid Puerto Rico in its recovery from Hurricane Maria by sending hundreds of Powerwall battery systems to the American Commonwealth, whose 3.5 million citizens still do not have access to electricity. Because full power is not expected to be restored for months, the Powerwall energy storage systems, which can be paired with solar panels, could prove to be vital tools as Puerto Rico and its partners work to restore safety and stability to the island.

First introduced in 2015, the Powerwall is Tesla’s home-based battery system, which is able to store energy captured during the day from solar panels and enables solar energy to be used even at night. Some of the Powerwall battery systems have already arrived in Puerto Rico, with more on the way. Tesla employees are on the island, working to install the systems and additional solar panels and repair existing solar panels. They are also collaborating with local groups to determine the best locations for these battery systems to be implemented. In addition, Tesla co-founder and CEO Elon Musk has personally donated $250,000 to the relief efforts in Puerto Rico.

Prior to its efforts in Puerto Rico, Tesla had assisted in the evacuation efforts in Florida as Hurricane Irma approached the peninsula. After receiving a request from a Tesla owner who wished to evacuate from their home in Florida, but who was concerned about the car’s ability to go the distance, Tesla released a software update which extended battery range. Ultimately, Tesla decided to extend the battery range for all Model S and Model X cars from 60-70 kilowatt hour to 75 kwh.
