Seminoe Power Company is moving closer to construction of the Miller Generating Station, prompting elected officials to consider how the natural gas powerplant will affect Carbon County.
Seminoe Power Company is an affiliate of Power Company of Wyoming. Both entities operate under Anschutz Corporation, a Colorado‑based energy investment firm. In 2025, Anschutz proposed building a 2,000‑megawatt natural gas power plant south of Sinclair. Through its wholly owned subsidiary, Power Company of Wyoming, the corporation is working to supplement electricity generated by the nearby 3,000‑megawatt Chokecherry Sierra Madre wind project. Together, the two facilities are intended to meet the state’s rising energy needs, including increased demand from AI data centers.
This past January, representatives from Power Company of Wyoming met with the Board of Carbon County Commissioners to discuss the Miller Generating Station. During that meeting, Executive Vice President of Engineering and Construction Ryan Jacobson explained that the facility would occupy roughly 70 acres of private land owned by the Overland Trail Ranch south of Rawlins and Sinclair, near the Chokecherry Sierra Madre wind farm. Jacobson said the site was chosen for its direct access to nearby natural gas pipelines and the existing electrical transmission infrastructure.
Last month, Seminoe Power Company applied for an Industrial Siting Permit from the Wyoming Department of Environmental Quality to build, operate, and maintain the Miller Generating Station. Construction is expected to begin in the third quarter of 2027, reaching a peak workforce of 914. On average, 492 workers will be on‑site during the 70‑month construction period. Seminoe Power Company estimates that 42 full-time employees will be needed to run the facility upon completion.
As part of the permitting process, the Industrial Siting Council must determine the project’s impact on local roads, housing, and emergency services.
During the October 6th Board of Carbon County Commissioners meeting, Commission Chairman Travis Moore announced that the Board received a notice to participate in the Industrial Siting Permitting Process for the Miller Generating Station. Information provided by the county will be used by the Industrial Siting Council to determine how to distribute the project’s nearly $56 million of impact‑assistance funding between Carbon and Sweetwater Counties. Commissioner Sue Jones recommended bringing together all county entities, including the Fire Protection District, Memorial Hospital of Carbon County, South Central Wyoming EMS, and the affected municipalities, before responding to the Industrial Siting Council.
County officials agreed that everyone should meet before submitting an impact‑assistance request to the state. Deputy County Attorney Ashley Davis explained that the session will allow the individual entities to understand that the Industrial Siting Council will only approve requests for funding that are directly tied to the project.
Seminoe Power Company has indicated that workers will be housed on-site during construction of the Miller Generating Station. With a projected peak workforce of 914, Deputy Attorney Davis noted that many of those crew members will travel to Seminoe Reservoir during their off time. She said the county may seek impact‑assistance funding to rebuild a portion of Seminoe Road due to the expected increase in traffic.
County officials agreed to hold a meeting with all affected entities tomorrow, October 13th.
During the October 7th Saratoga Town Council meeting, Clerk Jennifer Anderson announced that the town received the county’s invitation. Clerk Anderson said municipalities are expected to present their anticipated impact assistance funding requests at that October 13th meeting. Mayor Chuck Davis said he anticipates that a number of Seminoe Power Company’s construction and full-time employees will live and recreate in Saratoga.
Mayor Davis said the influx of workers will have an effect on the town’s sewer and water infrastructure, police department, and the Hobo Hot Springs. In addition, the mayor said the expected population increase will also place more strain on the local schools.
Mayor Davis asked the Town Council to give him their ideas for potential impacts stemming from the construction and operation of the Miller Generation Station so he can represent Saratoga at tomorrow’s county-wide meeting.
The county’s impact assistance funding requests must be submitted to the Industrial Siting Council by Thursday, October 22nd.
Seminoe Power Company intends to begin commercial operation of the Miller Generating Station in 2031, with full functionality expected by 2033. The natural gas powerplant is not affiliated with the proposed Seminoe Pumped Storage Project being developed by rPlus Hydro.
