Agency leaders and stakeholders have until May 26 to submit comments to the Federal Energy Regulatory Commission, or FERC, regarding the “pre-application document” for a proposed $2 billion pumped-hydro-storage clean energy project that could be built southeast of Craig.
On March 27, around 40 people attended or listened remotely to a meeting hosted at Colorado Northwestern Community College that provided updated information on the project proposed by Salt Lake City-based rPlus Hydro. The presentation at the joint agency meeting included an overview of the project and operations and a review of information in the FERC pre-application document. The meeting outlined proposed studies to be conducted by rPlus Hydro for the FERC licensing process and provided agency representatives and stakeholders the opportunity to give feedback. A smaller group attended an afternoon tour at the proposed site…
Shapiro said water use from the Yampa River would not be extensive at 4,000 acre-feet of initial fill for the project’s lower reservoir, plus some 600 acre-feet of water annually to account for evaporation and seepage from two new reservoirs on 170 acres. The goal would be to use a portion of the water rights already owned by the coal-fired power plants, Shapiro said…
The majority of the pumped-hydro system would be located underground, including a below-ground powerhouse with three pump-turbine units with generation capacity of 200 megawatts each. The project would consist of one upper and one lower reservoir joined by 2.5 miles of underground water tunnels, an above-ground switchyard, access tunnel, tailrace surge chamber and accessary facilities.
An electric transmission line from the project would run either 11 miles to Craig or less than 2 miles to a Western Area Power Administration line, Shapiro said. Target completion of the licensing process is estimated for 2028, with construction from 2029 to 2033, Shapiro said.
