There’s no doubt about it: California’s decade-long efforts to expand the use of solar, wind, and other renewable energy and improve energy efficiency have enabled the state to significantly reduce its consumption of natural gas for power generation. But the Golden State’s rapid shift to a greener, lower-carbon electricity sector — and its push to shut down gas-fired power plants — has come at a cost, namely an increased risk of rolling blackouts, especially during extended heat waves in the West when neighboring states have less “surplus” electricity to send California’s way. The main problem is that while solar facilities provide a big share of the state’s midday power needs, there’s sometimes barely enough capacity from gas plants and other conventional generation sources to take up the slack when the sun sinks in the late afternoon and early evening. Today, we discuss recent developments on the power front in the most populous state, and what they mean for natural gas consumption there.
