About the California grid region
The California region is anchored by the California ISO (CAISO), which schedules most of the state’s load. It leans heavily on solar, which means demand on the wires swings hard at sunset, the famous duck curve. CAISO Flex Alerts are polled directly and override this region to CRITICAL when declared.
On the map, this region is part of the Western Interconnection. Its status color comes from the ratio of actual demand to the bias-corrected day-ahead forecast: green means headroom, amber and orange mean it is tightening, and red means demand has met or passed what the operator expected, or a real emergency has been declared.
