San Francisco – Today, San Francisco Mayor London N. Breed, Oakland Mayor Libby Schaaf, San Jose Mayor Sam Liccardo, and Berkeley Mayor Jesse Arreguín announced their support for Senator Scott Wiener’s (D-San Francisco) Senate Bill 378. SB 378 puts in place reasonable, commonsense mechanisms to ensure that utilities are pursuing planned blackouts with adequate prudence, that utilities aren’t knee-jerk shutting off power to eliminate liability risk, and that the negative consequences of blackouts on local communities are minimized.
