| Values for 2023 and prior years are final. Values for 2024 are preliminary. Time adjusted capacity for month rows is the summer capacity of generators in operation for the entire month; units that began operation during the month or that retired during the month are excluded. Time adjusted capacity for year rows is a time weighted average of the month rows. Capacity factors are a comparison of net generation with available capacity. See the technical note for an explanation of how capacity factors are calculated.
