Cal Iso Calls Flex Alert For The Weekend

People use more energy when it's hot and California's power grid operator has issued a Flex Alert because of the current heat wave.

Cal-Iso is the state's Independent System Operator. When the forecast for demand gets close to the state's power generating capacity, the operator calls a Flex Alert.  Stephanie McCorkle with Cal-ISO says it's most important to conserve during the peak useage hours between 11 a.m. and 6 p.m., " Electricity is not something you can bottle up and store on a shelf.  It is basically consumed the instant it is produced." 

McCorkle says the power grid has a maximum capacity of 54,000 megawatts, but that there is almost never that amount actually available.  The forecast demand for today (Friday) is about 47,000 megawatts.   

A Flex Alert is also expected for Saturday and Sunday.
