Skyhawk air conditioners, new homes, overwhelm electrical grid

Kevin McCallum, THE PRESS DEMOCRAT

A normally quiet east Santa Rosa street has been turned into a noisy power station to meet the growing power demand by large, air-conditioned homes and new development that threatened to overwhelm the area’s power grid.

Pacific Gas and & Electric set up a series of mobile power generators on Great Heron Drive in the Skyhawk neighborhood last week after power went out to 109 customers in the area Aug. 31, PG&E spokeswoman Deanna Contreras said.

Worried by a forecast that called for triple-digit temperatures over the Labor Day weekend, the utility wanted to make sure it could keep the lights and air conditioners on in the area, she said. The mercury ended up hitting a new record of 110 degrees in Santa Rosa last Saturday.

The neighborhood of mostly larger single-family homes built in the 1980s and 1990s had an undersized electric infrastructure that was stressed when people turned on their central air conditioners.

The operator of California’s power grid has issued a so-called Flex Alert calling for voluntary electricity conservation between 2 p.m. and 9 p.m. on Tuesday and Wednesday, the expected peak of the current heat wave.

The California Independent System Operator says consumers shouldn’t use major appliances during those hours and should set air conditioners to 78 degrees or higher and turn off unnecessary lights to ease strain on the grid.

The forecast peak electricity usage is expected to exceed 47,000 megawatts each day.
