Heat Wave Brings Triple Digit Temperatures To Southern California

ALHAMBRA, CA - JULY 25: Director of Alhambra Grid Operations Tracy Bibb keeps an eye on the state?s power usage near the dispatch board in the California Independent System Operator (Cal ISO) Alhambra Control Center after a Stage 1 power emergency was announced July 25, 2006 in the Los Angeles area city of Alhambra, California. During a Stage 1 power emergency, residents are encouraged to conserve as much electricity as possible to avoid a Stage 2 emergency. A Stage 2 alert means that remaining available power has fallen below five percent and some businesses will voluntarily shut down parts of their operations in exchange for discounted rates. A Stage 3 alert would mean that power resources have fallen so low that ?rolling blackouts? must be implemented to prevent a failure of the power system. (Photo by David McNew/Getty Images)
