PG&E officials are recommending careful energy conservation today and during the week's forecasted heat wave after more than 30,000 Castro Valley customers lost power Saturday due to system overload.
Saturday's power outage was reported just before 6 p.m. and affected up to 33,680 customers in Castro Valley and Hayward, PG&E spokesman J.D. Guidi said.
The cause of the power loss was a heat-related equipment failure at PG&E's Castro Valley substation, Guidi said.
Power was fully restored to the area by about 8:40 p.m., Guidi said.
High temperatures were around 90 degrees Saturday and forecasted to push even higher today and Monday.
To help stave off the possibility of further heat-related outages, PG&E recommends shutting windows and keeping blinds closed in the morning to save cool air indoors from the night before. PG&E also recommends turning off lights and appliances when they're not being used and resetting air conditioning to around 85 degrees when out of the house and around 75 degrees when home.
