California Power Bills: Renewable Mandates Drive Prices to Double the National Average

California residents are paying roughly twice the national average for electricity, a gap that has widened since the state implemented its Renewable Portfolio Standard. This price increase coincides with a rise in the share of power generated by wind and solar resources mandated by state law.

According to the latest pricing data from the Energy Information Administration, the current premium is approximately 100% above the national average. Before the RPS was enacted, California electricity prices were 40% to 50% higher than the national mean. The data indicates that states with stricter renewable requirements consistently see higher and faster-growing electricity prices compared to states without such mandates.

State law dictates that 60% of California's electricity must come from renewable sources like solar and wind by 2030. This requirement will rise to 100% by 2045. Nuclear power, which produces fewer lifetime emissions than solar and comparable amounts to wind, is excluded from these renewable calculations.

The intermittent nature of wind and solar power requires backup generation to ensure supply when the sun is not shining or the wind is not blowing. The California Energy Commission has decided not to renew contracts for three aging natural gas units in Ormond Beach, Alamitos, and Huntington Beach that expire at the end of December 2026. The state now prefers utility-scale lithium-ion battery energy storage systems for backup, though these facilities face risks, as demonstrated by fires at the Moss Landing and Gateway sites.

Transmission infrastructure adds another layer of cost. Solar and wind facilities must be located in specific areas, often far from population centers, necessitating extensive new transmission lines. These longer lines through fire-prone terrain can increase ignition risks if they are not hardened or carefully routed, adding to the maintenance and construction expenses passed to consumers.

Wayne Winegarden, a senior fellow at the Pacific Research Institute, notes that tracking the RPS requires utilities to buy Renewable Energy Credits. California imposes strict limits on which credits are acceptable, a policy that may obstruct interstate commerce. West Virginia is currently suing Pennsylvania over similar closed-border policies. Winegarden argues that reforming these mandates allows utilities to manage expenditures more effectively, potentially lowering the energy cost burden for families.
