FOLSOM, Calif.--(BUSINESS WIRE)--The California Independent System Operator Corporation (ISO) is reminding Northern Californians that a Flex Alert is in effect today, Tuesday, July 2, 2013. Consumers are encouraged to reduce their energy use between noon and 7 p.m., as air conditioners drive peak demand.
Actual peak demand was significantly under forecast yesterday, coming in at about 45,000 megawatts. A major factor in the reduced demand was Southern CA temperatures coming under forecast. However, Northern California peak demand was expected to break the all-time peak record and came in significantly shy of that 20,642 MW (record is 22,726 set on 7/25/06), which indicates that demand response programs and the voluntary conservation from the Flex Alert were very helpful in reducing the strain on the grid.
The ISO thanks its media partners and Northern Californians for their tremendous efforts and urges them to do the same during today’s Flex Alert. Go to www.flexalert.org or www.caiso.com for conservation tips.
