In Brief
Three weeks after Hurricane Maria hit Puerto Rico, the majority of the island is still without power. Now, Tesla is supplying the island with hardware that will help restore electricity in the hospitals and other medical centers where it's most needed.

Elon Musk has made no secret of his ambition to help Puerto Rico regain power after the devastation caused by Hurricane Maria. Previously, Tesla had sent a few hundred Powerwall battery packs to the island, and now, Musk’s company has officially started shipping Powerpacks to Puerto Rico as part of relief efforts.

With a capacity of 210 kWh, a single Powerpack 2 battery is equivalent to 16 Powerwall cells. The priority for this hardware is to supply hospitals and other medical centers with power so that staff can continue their work.

Three weeks after the hurricane hit, less than 20 percent of the island has access to electricity, but even before the disaster, Puerto Rico’s power grid was in dire need of modernization. Musk wants to renew rather than just repair, and last week, he met with the island’s governor to discuss what Tesla could do to improve its infrastructure.

By shipping these Powerpacks to Puerto Rico right now, Tesla is providing the island with a lifeline. Any major work on the power grid will take months, but this hardware should ensure that the most critical facilities can continue to operate in the interim.
