Pseudo-Original Article: California's Independent System Operator (ISO) announced on Tuesday (July 11th) that the state now has enough large-scale energy storage batteries to supply 5,600 megawatts of power, more than ten times the amount in 2020. According to the ISO, this is enough to power approximately 3.8 million households for about four hours. The energy storage batteries can absorb excess energy during the daylight hours when solar power generation is high and then supply power to the grid when the sun goes down in the evening. According to statistics from the Environmental Protection Agency, California accounts for approximately 40% of the total installed energy storage capacity in the United States.
