Aspen files preliminary paperwork with FERC for the proposed Castle Creek hydroelectric generation plant


From the Summit County Citizens Voice (Bob Berwyn):

The filing is the first step in a formal review process that eventually could enable the town to produce about 8 percent of its needed electricity from a clean and local source — but the project is not without controversy, as some critics claim that the power generated by the facility isn’t worth the potential harm it could cause to Castle and Maroon creeks by reducing stream flows.

For the town, the Castle Creek project is a key component in providing renewable energy sources to the Aspen community. According to the town’s website, the energy center will not only provide power, but serve as a renewable energy model, education center and museum, reducing CO2 emissions by about 5,000 tons. The turbine and generator convert the force of water falling from 325 feet, from the Thomas Reservoir, into electric power. The water will travel a 42 inch penstock (pipe) which will supply the plant with approximately 52 cubic feet per second of head and double as an emergency drain line for the Thomas Reservoir if the reservoir walls are breached. The electricity will be placed on the City of Aspen electric grid to power the Water Treatment campus, and may potentially produce hydrogen for fuel cells and hydrogen vehicles.
