"Batteries provided 12.3 gigawatts of power—roughly as much as six Hoover Dams—at 7pm on March 29, meeting 43% of the total grid demand."
"The cost of batteries has dropped 99% over the last three decades, with a significant one-third reduction in the last few years, making them more accessible."
"By using batteries to store excess solar power, California's grid can rely less on energy imports and expensive peaker gas plants during peak demand."
"Gas electricity generation in California contributes to 30 to 40 million metric tons of CO2 emissions annually, impacting health in low-income communities."
On March 29, California's electric grid achieved a milestone with batteries supplying 12.3 gigawatts, about 43% of total demand. This storage capability, primarily developed in the last five years, is attributed to significant cost reductions in battery and solar technologies. The cost of batteries has decreased by 99% over three decades, with a one-third drop in recent years. Utilizing batteries with solar energy allows California to reduce dependence on expensive gas plants, particularly during peak demand, while also addressing environmental and health issues in affected communities.
