I was aware that Puerto Rico had suffered a whole island black out last week when a tree fell on some power lines and then read today about another whole island blackout due to some construction equipment. No mention of Telsa's efforts and it had me wondering how those Tesla Powerwall and Powerpacks were doing. Found this InsideEvs article that reported all is well and good. Nice.
