On the windswept plains of Bonneville County, Idaho, the Goshen Phase wind project represents a significant stride in the state’s pursuit of its vast, untapped renewable energy potential. As a major utility-scale development, it underscores Idaho’s evolution beyond its historic reliance on hydropower, diversifying its clean energy portfolio with a new, homegrown resource that provides economic stimulus to the local community while feeding power into the regional grid.
Significance & Context
The Goshen Phase wind farm, developed by Ridgeline Energy (a portfolio company of Apex Clean Energy), is a landmark project in Idaho’s energy landscape. With an installed capacity of 120 megawatts (MW), the facility generates enough electricity to power approximately 35,000 Idaho homes annually, based on U.S. Energy Information Administration (EIA) calculations. Its output is purchased by Idaho Power under a long-term Power Purchase Agreement (PPA), directly contributing to the utility’s 100% clean energy by 2045 goal.
Development Timeline
The project’s development navigated Idaho’s regulatory environment. Initial prospecting began in the late 2010s. After securing county permits and finalizing the PPA, construction commenced. The Goshen Phase project achieved commercial operation in 2020, a date confirmed by its listing in the comprehensive U.S. Wind Turbine Database.
Technology & Innovation
The project employs modern, high-efficiency turbines, featuring 43 Siemens Gamesa wind turbines in the 2.6-2.7 MW class. A key focus was designing a layout compatible with agriculture, aligning with land-use best practices for wind energy documented by the National Renewable Energy Laboratory (NREL). The project incorporates advanced monitoring for grid integration.
Challenges & Controversies
A significant challenge was navigating the concerns of the local community and county officials regarding visual impact and rural character. This hurdle was resolved through proactive engagement. Ridgeline Energy conducted public meetings and worked within the county’s conditional use permitting process. The project’s approval by the Bonneville County Planning and Zoning Commission was contingent on this dialogue.
Community & Economic Impact
For Bonneville County, the wind farm provides a valuable new source of long-term revenue. During its construction phase, the project typically employed 150-250 workers, according to American Clean Power Association industry models. In its operational phase, it generates a stable stream of property tax revenue for the county, providing crucial funding detailed in Bonneville County financial records. Furthermore, it provides guaranteed annual lease payments to participating landowners, a benefit for the agricultural economy supported by University of Idaho Extension.
Future Outlook
As a new, technologically advanced facility, the Goshen Phase project is positioned for a long operational life. Its success has helped validate the wind resource in eastern Idaho. Given its modern turbine technology, repowering is a consideration for the distant future, a strategy analyzed in NREL reports on wind plant modernization. For now, it stands as a foundational asset in Idaho’s energy mix.
