On Thursday, Musk tweeted that his company has built solar grids for many small islands, adding that there "is no scalability limit, so it can be done for Puerto Rico too."
Puerto Rico Governor Ricardo Rossello responded early Friday saying: "Let's talk today; I will be in touch."
Musk tweeted back saying that he would be "happy to talk."
Last month, Puerto Rico was badly hit by Hurricane Maria. Electricity is not up and running yet and millions of citizens are struggling without basic necessities.
Tesla makes the Powerpack storage battery, which it's deploying in other countries. For example, Musk won a contract from South Australia to install a 100 megawatt facility, which could power 30,000 homes.
