±ØÍþÌåÓý¹Ù·½APPÏÂÔØ constructed the Rush Creek wind project substations and collection system in Limon, CO, for Xcel Energy. Rush Creek is the largest single-phase wind project ±ØÍþÌåÓý¹Ù·½APPÏÂÔØ has ever built as well as Colorado’s largest, boosting the state’s wind generation capacity by 20 percent and powering an estimated 660,000 homes.

The power delivery infrastructure was a critical component in enabling the success of the broader wind project and supported Xcel’s goal of adding renewable energy to their portfolio. Rush Creek will eliminate about a million tons of carbon dioxide annually that would have been produced otherwise, in addition to providing other local benefits like land lease payments and property tax revenue. The project is a key piece of Xcel’s ‘Colorado Energy Plan�, which is “is Xcel Energy’s roadmap to develop a significantly cleaner energy mix and reduce carbon emissions in Colorado� all while keeping customer bills low.� Effective power delivery infrastructure is a key component in taking full advantage of renewable energy projects.

The two massive 345kV / 34.5kV substations each contain two main power transformers. Rush Creek 1 substation is carrying 15 feeders (fed by 190 wind turbines), and Rush Creek 2 substation is carrying 8 feeders (fed 110 wind turbines), and 1.05 million feet of trench connect to the 300 Vestas turbines that cover nearly 100,000 acres across five counties in Eastern Colorado.

±ØÍþÌåÓý¹Ù·½APPÏÂÔØ self-performed the collection system and both substations, with the exception of the cable installation and substation foundations, which we completed with our trusted trade partners.
