California is at Almost a critical threshold on their power grid. When they add all of electric cars this summer the might see a blackout that last fo weeks. It is close to a catastrophic cascade failure and it will difficult to bring the system back on line. Our grids cannot support much more load. Good luck! Texas Almost lost its grid last year. Sustained high temperatures will test all of the grids.
A little good news for California , people are getting rid of their Tesla so that will help ,LOL
