In the United States, wind speeds, and correspondingly, wind-powered electricity generation, often peak during spring. On March 29, the Southwest Power Pool (SPP), which covers parts of Oklahoma, Kansas, Nebraska, North Dakota, South Dakota, and neighboring states, and the Electric Reliability Council of Texas (ERCOT) both reported new wind penetration records. Wind penetration represents the share of electric demand satisfied by wind generation. SPP reported wind penetration of 88.5% on March 29, and ERCOT reported wind penetration of 67.2% for the same day.
On a monthly basis, we have had less wind generation in the United States than natural gas-fired generation, coal-fired generation, or nuclear generation. We do not expect wind to surpass either coal-fired or nuclear generation for any month in 2022 or 2023.
