Energy Emergency Alert Issued: Carlsbad Residents Urged To Curb Energy

CARLSBAD, CA — For the second day, the California Independent System Operator issued an Energy Emergency Alert 2 Wednesday amid a record-breaking heat wave in the Golden State.

The alert, which is in effect from 4-9 p.m., means the state's power grid manager has requested emergency supplies from all resources to meet what is expected to be a heightened demand for electricity. Cal ISO had already extended a Flex Alert for the eighth consecutive day to urge residents in Carlsbad and across the state to conserve power during the same hours to avoid rolling blackouts.

Californians are asked to set thermostats to 78 degrees or higher; avoid use of major appliances; turn off unnecessary lights; and avoid charging electric vehicles. Residents are also advised to pre-cool their homes as much as possible and close blinds and drapes to keep interiors cool.

The voluntary conservation measures have worked so far, as the power stayed on Tuesday despite a record demand for electricity.

"Consumer conservation played a big part in protecting electric grid reliability," Cal ISO officials said on Twitter after the Energy Emergency Alert 3 ended at 8 p.m. Tuesday.

Temperatures have soared above 100 degrees every day since last Wednesday in Southern California.

An excessive heat warning that was in effect over Labor Day weekend was extended until 8 p.m. Friday for San Diego County, according to the National Weather Service. Dangerously hot conditions are expected in the region.
