During a record-setting cold wave from Feb. 14-20, 2021, Texas electricity prices spiked to $9,000 per megawatt-hour, more than 100 times higher than typical rates. When the spike eased, regulators restored it in an effort to induce Texans to conserve power. Prices shown are for ERCOT's Houston generating region, but were extremely similar across all of ERCOT's territory, covering most of the state.
