Wyoming Renewable Power Stations and Energy Infrastructure
Wyoming is diversifying its energy portfolio by leveraging its unique geography to harness a variety of renewable resources. From the vast, wind-swept plains to the rushing waters of its river systems, the state utilizes a mix of wind, solar, hydroelectric, and biomass energy to power its infrastructure. Using data from the U.S. Energy Information Administration, we can see a comprehensive map of how the state is transitioning toward sustainable power generation.
While traditional energy sources have long defined the region, the growth of utility-scale renewable projects—particularly in wind and solar—demonstrates a significant shift in the state's energy landscape.
Key Facts
- Wind Power: The dominant renewable source, with the massive Chokecherry and Sierra Madre project expected to be the largest in the U.S. by 2026.
- Hydroelectric: A long-standing pillar of the state's grid, with the Fremont Canyon station providing the highest capacity at 66.8 MW.
- Solar Energy: Growing rapidly, highlighted by the 150 MW South Cheyenne Solar plant completed in 2024.
- Biomass: Utilized through industrial waste heat recovery, such as at the Simplot Phosphates facility.
- Geothermal: Currently limited to small-scale building heating; no utility-scale facilities exist in the state.
Wind Energy: The Powerhouse of the Plains
Wind energy is the most prolific renewable sector in Wyoming. The state's open terrain provides ideal conditions for large-scale turbine arrays. Projects like the Cedar Springs Wind Farm (531.56 MW) and TB Flats I and II (301.1 MW) contribute significantly to the regional grid.
The most ambitious project currently underway is the Chokecherry and Sierra Madre Wind Energy Project in Carbon County. Scheduled for completion in 2026, it aims for a capacity of up to 3,000 MW using approximately 1,000 turbines. Once finished, it will be the largest wind farm in the United States, utilizing High Voltage Direct Current (HVDC)—a technology that allows for efficient long-distance power transmission—to serve the western U.S. market.
Hydroelectric and Solar Power
Hydroelectric power provides a steady baseline of renewable energy. Wyoming's facilities range from the historic Shoshone plant (completed in 1922) to more modern installations like Swift Creek (completed in 2010). These stations utilize the natural flow of water to drive turbines, with the Fremont Canyon and Seminoe stations serving as some of the highest-capacity sites.
Solar energy is a more recent addition to the utility-scale mix. The South Cheyenne Solar plant, completed in 2024 with a capacity of 150 MW AC (Alternating Current), and the Sweetwater Solar plant (92 MW) represent the state's commitment to capturing solar radiation for electricity.
Biomass and Geothermal Energy
Wyoming also employs biomass energy, specifically through the recovery of industrial waste heat. The Simplot Phosphates facility in Sweetwater County is a prime example; it uses a steam turbine to convert waste heat from phosphate fertilizer manufacturing into 11.5 MW of power.
In contrast, geothermal energy—power derived from the earth's internal heat—is not yet utilized at a utility scale in Wyoming. While there are several small-scale installations used for heating buildings, there are currently no large-scale geothermal power plants.
Renewable Energy Summary

| Solar | South Cheyenne Solar | 150 | Recent utility-scale expansion |
| Hydroelectric | Fremont Canyon | 66.8 | Established infrastructure |
| Biomass | Simplot Phosphates | 11.5 | Industrial waste heat recovery |
| Geothermal | Small-scale heating | N/A (Utility scale) | Non-utility use only |
