The International Consortium of Energy Managers on Jan. 31 sent in to the Federal Energy Regulatory Commission a tardy six-month update under the preliminary permit for the 450-MW Blue Diamond Pumped Storage Project in Nevada.
The company said it undertook the following tasks during this latest reporting period:
- The company conducted additional detailed site visits.
- It continued reviewing public comments in the FERC record, and discussed with stakeholders alternatives to the project description shown in the Preliminary Permit.
- The company worked on the issues of water rights and power purchase arrangements.
- The company’s representatives actively participated in a number of regulatory proceedings in California relative to storage and connecting into the California grid.
- The company is discussing with investors additional funding for the project.
- The company’s representatives are actively participating in a number of regulatory proceedings in California relative revenue sources for storage and firming resources.
FERC in July 2012 granted the consortium a preliminary permit to study the feasibility of the Blue Diamond Pumped Storage Project, to be located in Clark County, Nev. The proposed project would be closed loop and would not be located on any existing water body. The preliminary permit granted three years of exclusivity to look at project feasibilty, with a license application then required if the decision is to keep moving the project forward.
It would consist of: a new embankment creating an upper reservoir with a maximum elevation of 4,810 feet above mean sea level (MSL), and a storage capacity of 4,900 acre-feet; a new embankment creating a lower reservoir with a maximum elevation of 3,320 feet MSL, and a storage capacity of 4,900 acre-feet; a 21-foot-diameter, 4,300-foot-long concrete and steel penstock; a powerhouse containing two pump/turbine units with a total installed capacity of 450 MW; and a 132-kV, 3.5-mile-long transmission line. The proposed project would produce about 4,500 megawatt hours (MWh) of energy daily, and use about 5,600 MWh daily to pump water from the lower to the upper reservoir.
