Annual DOE Report Shows Technology Advancement and Value of Wind Energy
Inflation Reduction Act promises new market dynamics for wind deployment and supply chains
We are pleased to announce the release of the U.S. Department of Energy (DOE)’s annual “Land-Based Wind Market Report: 2023 Edition.” The release provides an updated overview of data and trends in land-based wind energy in the U.S., in the form of a report, a briefing slide deck, a data file, and a series of interactive data visualizations.
Wind energy continues to see growth, solid performance, and attractive prices. Though 2022 was a relatively slow year for new wind power deployment compared to the previous two, the Inflation Reduction Act promises new market dynamics in the years ahead. Key highlights of the new report include:
Wind comprises a growing share of electricity. U.S. wind power deployment totaled 8.5 gigawatts (GW) in 2022, representing a $12 billion investment. Wind energy contributed more than 10% of the nation’s electricity supply, and as much as 38% in the Southwest Power Pool. A record-high 300 GW of wind is seeking transmission interconnection.
Turbines continue to get larger. Improved plant performance over the last decades has been driven by larger turbines mounted on taller towers and featuring longer blades. In 2012, only 1% of turbines employed rotors that were 115 meters in diameter or larger, while 98% of newly installed turbines featured such rotors in 2022. Proposed projects indicate that total turbine height will continue to rise.
Wind energy prices have risen, but remain attractive for purchasers. Wind power purchase agreement prices have been drifting higher since about 2018, with a recent range from below $20/MWh to more than $40/MWh depending on region and other details. These prices, which are possible in part due to federal tax support, are similar to recent solar sales prices and to the projected future fuel costs of gas-fired generation.
The grid-system value of wind surged in 2022 across many wholesale power markets. The value of wind in wholesale power markets is affected by the location of wind plants, their hourly output profiles, and how those characteristics correlate with real-time electricity prices and capacity markets. The market value of wind generally increased in 2022, driven higher by high natural gas and wholesale power prices. The highest market value averages were in New England and California (above $75/MWh), with the lowest values in the Southwest Power Pool ($18/MWh).
The average levelized cost of wind energy was $32/MWh. Levelized costs, which exclude the impacts of federal tax incentives, vary across time and geography. The national average stood at $32/MWh for wind power plants built in 2022, driven lower by the concentration of new wind projects in the nation’s lowest-cost wind regions: Texas and the Southwest Power Pool.
The health and climate benefits of wind in 2022 far exceeded the levelized cost of wind. Wind generation reduces power-sector emissions of carbon dioxide, nitrogen oxides, and sulfur dioxide. These reductions, in turn, provide public health and climate benefits that vary regionally, but together are economically valued at an average $135/MWh-wind nationally in 2022.
The domestic supply chain began 2022 in decline, but passage of the Inflation Reduction Act created renewed optimism. Domestic manufacturing of towers and nacelles was strong in 2022, but blade manufacturing has plummeted in recent years. The Inflation Reduction Act contains, for the first time, production-based tax credits for domestic manufacturing of key wind components like nacelles, towers, and blades; it also extends the tax credit for wind deployment, inclusive of a new 10% bonus for projects that meet domestic content requirements. Consequently, there have been at least eleven announcements of manufacturing facilities that plan to open, re-open, or expand to serve the land-based wind industry.
Energy analysts project growing wind deployment, spurred by incentives in the Inflation Reduction Act. The Inflation Reduction Act provides a long-term extension of tax credits for wind energy along with opportunities for wind plants to earn two 10 percent bonus credits. The average wind deployment forecast for 2026 among analysts is 18 GW, a significant increase from the 11 GW 2026 forecast from a year ago (before the Inflation Reduction Act).
