California blackouts, power outages: Could it happen again today? – KCRA Sacramento

The hum of air conditioners returned after hundreds of thousands of Californians lost power in blackouts on Friday, but many wonder if the outages could return as temperatures soar into triple digits again.California ISO, which monitors the state’s electricity needs and power grid capabilities, issued a Stage 3 System Emergency on Friday because there was an electricity reserve deficiency.At the peak usage time, around 7 p.m., the data showed demand was at 46,777 megawatts. The forecasted peak for Friday was 46,824 megawatts. And the forecasted peak for Saturday is not much less than that, at 46,389 megawatts. Then look ahead to Sunday, when the current forecast puts the peak at 46,396 megawatts.California ISO has not yet issued any alerts this weekend for customers to reduce power consumption, but utilities are supposed to restrict maintenance operations.When a Stage 3 energy emergency is declared, like on Friday, utility companies are directed by California ISO to conduct rotating power outages in order to relieve strain on the electrical power grid — that includes PG&E. The increasing demand on the power grid comes as high temperatures are expected to reach 109 in Sacramento and other parts of California, according to the KCRA 3 Weather Team. The triple-digit heat will last until at least Wednesday, prompting KCRA 3 Weather Alert Days.PG&E said Friday’s rolling power outages were completed by 10:30 p.m. and power was essentially restored to all customers.”Pacific Gas and Electric Company (PG&E) has been directed by the California Independent System Operator (CAISO) to turn off power to approximately 200,000 to 250,000 customers at a time in rotating power outages given the strain on the power grid during the statewide heatwave,” PG&E said in a Friday statement about the energy emergency. “Other power utilities in the state are being directed to take similar actions.” PG&E’s rotating blackouts impacted El Dorado, Marin, Napa, San Mateo and Sonoma counties.PG&E said it was not be able to notify customers in advance about Friday’s outages. Officials also specified Friday’s power emergency was not a public safety power shutoff. PG&E explained those events are “conducted during specific high fire threat conditions.”SMUD, which manages power to the Sacramento County area, said it was not asked to conduct rolling blackouts.The California Office of Emergency Services created a power outage dashboard that allowed people to track the rolling blackouts. The data showed more than 338,000 customers were impacted at the peak of the outages.”We are in close contact with (California ISO) following their declaration of a statewide energy emergency due to high electricity use during the hot weather,” the California Office of Emergency Services said in a tweet. “OES is working with utilities and local officials to minimize the impact to Californians during potential rotating outages.”Earlier on Friday, Cal ISO issued a Stage 2 emergency and called a FlexAlert, asking residents to conserve energy.The last time the state ordered rolling outages was during an energy crisis in 2001.
