CAISO Grid Status (via) CAISO is the California Independent System Operator, a non-profit managing 80% of California’s electricity flow. This grid status page shows live data about the state of the grid and it’s fascinating: right now (2pm local time) California is running 71.4% on renewables, having peaked at 80% three hours ago. The current fuel mix is 52% solar, 31% natural gas, 7% each large hydro and nuclear and 2% wind. The charts on this page show how solar turns off overnight and then picks up and peaks during daylight hours.
