Storing Sunshine: Bay Area company cleans up affordable backup power
In August, California experienced its worst electricity crisis in nearly two decades. From PG&E to San Diego Gas & Electric, blackouts rotated across the state as millions of Californians, housebound by a pandemic, tried to stay cool during record-breaking heat.
The crisis showed the limits of the existing electrical grid, which buckled under too much demand and too little supply when it was needed. Problems arose late in the day, when the output from solar power declined. As the state looks to further increase the share of renewables on the grid to cut greenhouse gas emissions, the risk of supply shortages could increase. State energy leaders wrote in a letter to the governor: “Our changing electricity system may need larger reserves.”
Three years ago, the cofounders of Antora Energy anticipated this very problem.
