Federal Agency: California Grid Leaned on Natural Gas to Avoid Heat Wave Outages

During an extreme heat wave in early September, the California power grid relied on natural gas for almost half of its electricity generation to meet peak demand, the U.S. Energy Information Administration said on Wednesday.

For brief periods during the week of Sept. 4, natural gas accounted for up to 60% of the California Independent System Operator fuel mix, compared with 32% for the year prior to the record-setting demand week, the EIA said.

CAISO typically relies on natural gas, hydroelectric power, and electricity imports to meet peak demand, the EIA said, adding that less efficient and costlier natural gas units are often the last resort.

During the hours between 5 p.m. and 9 p.m., when cooling demand peaks and solar energy output wanes, the share of natural gas in the mix rose to more than half for the week of Sept. 4, CAISO data showed.

Meanwhile, the share of lower carbon-emitting sources, such as solar, wind and nuclear, dropped to 24% for the week of Sept. 4, from 40% for the year up to that week, the data showed.

The grid operator avoided rolling outages by urging customers to conserve energy for 10 consecutive days through the heat wave, as homes and businesses in the drought-stricken region cranked up their air conditioners.
