CALIFORNIA ISO CALLS FOR ENERGY CONSERVATION

Morning Hours Between 5-9 a.m. are Critical

(Folsom, CA) The season’s most severe winter storm yet is anticipated to increase consumer demand for power at a time when energy reserves are already strained. As a result, the California Independent System Operator (California ISO) has declared Thursday, January 11th a Power Watch Day. The California ISO urges Californians to watch their energy consumption, curtailing their use of electricity whenever possible. Power reserves have been tight all week with limited imports available from the Northwest. Additionally, the amount of generation unavailable due to planned and forced outages will increase from 10,600 to 12,400 megawatts this evening when the Diablo Canyon Nuclear Generating Station reduces its operating capacity by 80%. Record high swells, that can cause the intake valves of the power plant to clog with sea kelp, are expected to hit the Central Coast shoreline tomorrow. Thursday’s peak demand on the ISO-controlled Grid is expected to reach 32,589 megawatts by about 6:00 p.m.
