System demand — or load — is the total power the grid is serving at any moment, in megawatts. It moves with weather, time of day and economic activity, and it is the backbone series behind almost every forecasting or capacity model.
California ISO serves California and a sliver of Nevada, peaking roughly 45,000–52,000 MW on hot summer evenings.
