Western Interconnection hourly electric power supply: 28 Dec 2025 - 3 Jan 2026
December 28 and 29 were the best days for solar energy production in the US West. Windpower produced all hours of the week. Hydroelectric produced the largest non-combustion electric supply.
First Time: U.S. Renewable Electricity Exceeded Coal-Fired Generation in April 2019
Predicted to be a short-lived trend, as windpower declines and consumer electricity demand increases in Summer.
