Michael Wara, director of Stanford University’s climate and energy policy program, said he’s not convinced that solar or wind power is a direct cause of the rolling blackouts. He noted that the energy shortage has been arising in the early evening hours, just as the grid would be expected to tap into non-solar energy sources.
“It’s not clear to me at all that this had anything to do with renewable energy,” Wara said. “The timing suggests problems with gas plants ... because they are a fill-in for solar as the sun sets. Something about that system didn’t work.”
California Independent System Operator CEO Steve Berberich agreed in a Monday press call that “renewables are really not a factor” driving the blackouts, citing the need for better storage, like Newsom and Del Chiaro.
“It’s simply a matter of raw capacity,” he said, calling for “an overbuild of renewables and a fairly extensive deployment of batteries.”
The pressure on state regulators to move forward with renewable energy storage, despite its costs, is increasing as the power blackouts continue. A coalition of consumer groups, environmentalists, school officials and business groups are calling on the governor and Legislature to pass AB1001, the School Disaster Resiliency Act, authored by Assemblyman Phil Ting, D-San Francisco, which would equip 2,000 schools with solar-charged batteries.
Funding would come from a revenue bond that would be repaid over time through school energy bill savings, according to the coalition.
“It’s elementary,” Dan Jacobson, state director for Environment California said. “Any third-grader can tell you that we need more solar power, not less, and we need more batteries to store that sunshine for use after the sun goes down.”
“These heat waves are going to keep happening with climate change,” Del Chiaro said. “So, let’s do more in-state renewable energy and renewably charged batteries ... let’s build a smarter grid that’s flexible to these kinds of events, and let’s solve climate change and reduce air pollution at the same time.”
