Puerto Rico Governor Ricardo Rossello may take up Tesla CEO Elon Musk's offer to rebuild the island's electrical system using Tesla's massive batteries and solar panels.

Musk said Thursday that Tesla could use its Powerpack batteries and solar panels to restore electricity to Puerto Rico. Tesla has already built similar systems on smaller islands like Ta'u in American Samoa, which can now run entirely on solar power.

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.

The idea could come to fruition.

"Let's talk," Rossello responded to Musk on Twitter early Friday, noting that such a system could be a "flagship project" for Tesla.

Tesla said it has already sent hundreds of its residential batteries, the Powerwall, to Puerto Rico in the wake of Hurricane Maria. The Category 4 storm knocked out power for the entire island's 3.5 million residents, and they may not get power again for another six months.
