Intermediate Generation

 

Brush generation facilityBrush Generation Facility, located in eastern Colorado, is a 307-megawatt multi-unit natural gas-fired  power plant complex operated by Colorado Energy Management.  Tri-State receives 70-megawatts of capacity and energy from Brush Unit 2 through a 10-year tolling agreement that began on Oct. 1, 2009.  Brush Unit 2 is an intermediate capacity resource, meaning that it would be dispatched after coal-based unit resources like Craig and Nucla stations, but before simple cycle gas resources like Limon and Brighton (Colo.) Generating Stations.

Fort LuptonJ.M. Shafer Generating Station, located north of Fort Lupton, Colorado, is a 272-megawatt natural gas-fueled, combined-cycle power plant owned by Tri-State.  As part of a 10-year tolling agreement with the plant's previous owner that began on July 1, 2009, Tri-State receives 150-megawatts of capacity from the facility and the remaining output is sold under contract to Xcel Energy.  J.M. Shafer Station is an intermediate capacity resource, meaning that it would be dispatched after coal-based unit resources like Craig and Nucla stations, but before simple cycle gas resources like Limon and Brighton (Colo.) generating stations.

Rifle Generating Station

Rifle Generating Station, located on Colorado's Western Slope near the town of Rifle, became a Tri-State asset in September 2002. This generating facility is an 85-megawatt, gas-fired, combined-cycle power plant that, prior to Tri-State's ownership, was known as American Atlas No. 1. As a combined-cycle plant, Rifle Generating Station is best described as an intermediate peaking resource, meaning that its energy would be dispatched after coal-based unit resources like Craig and Nucla stations, but before resources like Limon and Brighton (Colo.) generating stations.
