Chaffee County’s renewable energy resources were identified through the development of thematic maps using existing solar, wind, geothermal and biomass data from the the U.S. Department of Energy’s National Renewable Energy Laboratory in Golden.

The Chaffee County EnergyNow Geographic Information System (GIS) is comprised of 35 background information layers and 13 renewable energy layers depicting the county’s energy potential and inventory. Four of the 13 renewable energy mapping layers represent potential energy sources: solar, wind, geothermal and biomass.

 

Large Hydropower in the Upper Arkansas Valley

Water is diverted from the West Slope’s Fryingpan River Basin. A series of interconnected tunnels and small diversion dams, all at elevations above 10,000 feet (3,000 m), collect snowmelt and run it, via gravity, to the Charles H. Boustead Tunnel. The Boustead runs water underneath the Continental Divide 5.5 miles (9 km) before discharging it into Turquoise Reservoir just west of Leadville. Water then leaves Turquoise Reservoir via the Mt. Elbert Conduit, which runs nearly 11 miles (18 km) to the Mt. Elbert Forebay. Water is stored in the Forebay to build up “head” or energy before being dropped down over half a mile (1 km) in elevation to the Mt. Elbert Power Plant.

  The power plant takes its name from Mt. Elbert, Colorado’s tallest peak, and sits at its base. The two-unit facility is the largest federally owned and operated hydroelectrical power plant in the state of Colorado. It has a capacity of 200 megawatts and a maximum generating head of 477 feet (145 m). During nighttime hours, when power rates are less expensive, the reversible pump-back units take water from Twin Lakes – water already used at least once by the units to generate electricity – back up to the Forebay so it can be used again for even more power generation.

The Western Area Power Administration markets the power generated at the plant.
