Channelfog 2 Jul 08, 2021 04:15 AM Power Outage in Santa Barbara Prepare for more power outages as Summer demand increases while hydroelectric capacity decreases. Half of Hoover Dam power goes to CA and it is only operating @ 66% generating capacity due to low water. The Oroville Dam hydro plant will like;y shut down completely for the first time due to low water. Evenings when the PV arrays shut down will likely be the most problematic. My 93 year old mom sleeps with a CPAP machine that needs electricity. We'll look into some kind of battery back up. Has anyone else done this?
