EDF Renewable Energy told the Federal Energy Regulatory Commission in a six-month project update, filed April 30, that it is trimming down the size of its Swan Lake North Pumped Storage Project to meet the available grid capacity.
This is the fourth six-month report for the project since FERC issued a second preliminary permit for the project, with that second permit to expire on Oct. 31, 2015. The preliminary permit for this project is held by Swan Lake North Hydro LLC.
Since the prior report, project work has focused on:
- Identification of value streams from recently completed modeling has indicated that a facility larger than 400 MW would require a significant upgrade in transmission for the region. The developer will continue with its vision of fitting into the existing grid as best it can, and therefore a redesign effort to make the project smaller is nearing completion. The smaller facility is expected to have a 390-MW capacity and 8 to 10 hours of full power generation storage. The smaller capacity dictates that smaller reservoirs also will be acceptable.
- The second phase of geotechnical work concerning the upper reservoir and powerhouse portions of the site will be commenced in summer 2015. Further, a reevaluation of the lower reservoir geology will take place with additional geotechnical work. The collection of this information will be accelerated in order to include it the Final License Application (FLA) filing, which is expected in the third quarter of this year.
- Modeling investigations of value streams resulting from the addition of the Swan Lake facility to the Western Interconnect has been expanded upon to value the impacts of two new factors that are both anticipated to show signifigant increases in value for the project. Those factors are the reduced 390-MW size and the potential for a 50% renewable mandate for California as announced recently by California Gov. Jerry Brown.
- A new Interconnection Feasibility Study for interconnection and a special study of impacts on affected systems will begin this summer. The special study will be led by CAlSO and/or Bonneville Power Administration with coordination by the physical utility hosting the interconnection.

The Swan Lake North Pumped Storage Project, originally designed at 1,000 MW, is to be located near Klamath Falls in Klamath County, Oregon, and Newell in Modoc County, Calif. EDF Renewable Energy reported in October 2013 to the commission that it has taken over sole control of the Swan Lake North project. EDF said it originally was a joint venture partner with Swan Lake Holdings LLC on this project, but it became the sole owner as of July 2013.
