The Hyatt Powerplant at Lake Oroville began generating hydropower again after shutting down in early August for lack of water. On Jan. 3, the water level was 716 feet, or 39% of capacity, considerably higher than the 640 feet when the plant closed, which had not happened since it began operating in the late 1960s. The plant was not yet operating at full capacity as water was being conserved for use in the spring and summer. Water was being released at 900 cubic feet per second and was producing 30 megawatts of electricity, although the plant’s maximum capacity is 750 megawatts. The Sacramento Bee (Calif.), Jan 4, 2022 The power plant at Lake Oroville stopped generating electricity on Aug. 5 as the lake reached a new low and was at 24% of capacity. The Edward Hyatt power plant is one of the largest hydroelectric plants in the state and can provide roughly 1% of the state’s peak electricity demand.
