Project Location

The Swan Lake Energy Storage Project is located 11 miles northeast of the city of Klamath Falls, Klamath County, Oregon. Renewable electricity stored at the facility would be transmitted from the powerhouse along a 32.8-mile-long, 230-kilovolt (kV) aboveground transmission line to interconnect with the Malin Substation.

The developer carried out engineering and environmental surveys to evaluate project location alternatives including alternate transmission routes to determine a project footprint with the least overall impact to landowners, environmental, and cultural resources.  During the Pre-Application studies, which began in 2010, the development team initiated environmental surveys, hosted open houses/meetings, and participated in local events, all to encourage open discussion with community members, landowners, and public agencies about the design of the proposed energy storage project.  These studies, meetings, and hundreds of comments filled with the Federal Energy Regulatory Commission (FERC) generated valuable feedback that helped shape the project, as proposed in the October 2015 application filed with FERC.

The proposed transmission route has been carefully designed to utilize existing corridors when possible; to avoid sensitive or protected areas when feasible; and to limit surface disturbance and minimize the overall environmental footprint.

Project Schedule

In October of 2015, after five years of studies and consultation with resource agencies, stakeholders, and residents, the developer filed a formal application with the FERC for approval to construct, own, and operate the Swan Lake Energy Storage Project. In August of 2016 FERC held public and agency scoping meetings in Klamath Falls, Oregon to assist with the preparation of Federal Environmental Impact Statement (EIS) for the proposed project.

In August of 2018 FERC issued the Draft Environmental Impact Statement (DEIS) and in January of 2019 FERC issued the Final Environmental Impact Statement (FEIS) for the Swan Lake Energy Storage Project. The FEIS considers and includes the results of all the completed environmental, socioeconomic, cultural, and engineering work, as well as the comments, considerations, and concerns of landowners, community members, government agencies, and located elected officials. The FEIS concluded that adverse environmental impacts from construction/operation would not be significant with the implementation of FERC-recommended protection, mitigation, and enhancement measures. The FEIS also noted the development team’s efforts to downsize the geographic footprint of the project and adjust the transmission line corridor, changes based primarily on accommodating landowner requests, avoidance of sensitive and/or cultural and historic resources, or engineering/design considerations. 

On April 30, 2019 the FERC issued a 50-year construction and operational license to the developer for the Swan Lake Energy Storage Project. The License was issued after nearly a decade of project planning, development, and review; and it recognizes the clear public need for this energy storage infrastructure. The development team has worked diligently with stakeholders, including landowners, community members, local officials, and state and federal agencies, to identify the best possible route for the proposed transmission line.
