Earlier today, Puerto Rico's Electric Power Authority announced that the entire island was without power.

It's expected that it could take up to 36 hours to restore power, but in the meantime, some 662 Tesla batteries (a combination or Powerwall and Powerpack units) are up and running, supplying essential juice.
