FERC seeks update on 1,154-MW pumped storage project in N.M.

Project developer Mesa De Los Carros Hydro LLC was sent an Oct. 21 letter by the Federal Energy Regulatory Commission warning about a late six-month project update report on an 1,154-MW pumped storage project in New Mexico.

FERC in September 2012 granted the company a successive preliminary permit to study the feasibility of the project. A license application would then be needed if project feasibility is established. The permit application was from Symbiotics LLC.

The permit requires that an update on the project be filed every six months at the commission. The Oct. 21 letter said that first such report has not been filed and that the permit will be terminated in 30 days if the company doesn’t cure this default.

Mesa De Los Carros Hydro is studying the feasibility of the Mesa De Los Carros Pumped Storage Hydroelectric Project to be located in San Miguel County, N.M. The proposed project would be closed loop and would not be built on an existing body of water.

The project would include:

  • an upper earthen dam with a height of 88 feet and a length of 11,880 feet;
  • an upper reservoir with a surface area of 276 acres, a capacity of 10,394 acre-feet, and a maximum pool elevation of 6,900 feet above mean sea level (msl);
  • a lower earthen dam with a height of 110 feet and a length of 9,662 feet;
  • a lower reservoir with a surface area of 396 acres, a capacity of 11,652 acre-feet, and a maximum pool elevation of 5,560 feet msl;
  • a 29-foot-diameter, 9,000-foot-long, steel penstock;
  • a powerhouse containing four pump/turbine units with a total installed capacity of 1,154 MW; and
  • a 19.5-mile-long, 500 kV transmission line.

The project would have an annual production of 4,214 gigawatthours that would be sold to a local utility.
