California recently joined other leading states, provinces, cities, and corporations around the world by setting an ambitious 100 percent carbon-free electricity target. It’s a landmark, not because California was the first, but because it is the biggest. The state ranks as the fifth-largest economy in the world.
Achieving 100 percent carbon-free electricity means lots of wind and solar. Alongside more-flexible demand, balancing such renewable energy will involve bringing more energy storage onto California’s grid, to store surplus clean generation, which is where the state’s Self-Generation Incentive Program (SGIP) comes in.
