FERC No. 2645

The developments are operated in a coordinated manner as store-and-release facilities primarily to meet peak demand.  Flows reaching the Project are controlled by releases from the Hudson River-Black River Regulating District’s (Hudson-Black) Stillwater Reservoir Project No. 6743, located approximately five miles upstream of the most upstream Beaver River Project development, Moshier.

The Project was constructed between 1903 and 1930.  Four of the developments (Moshier, Eagle, Soft Maple and Taylorville) have extensive bypassed reaches.  These range from about 3,850 feet at Eagle to over 11,700 feet at Moshier.

The eight hydropower dams and powerhouses that comprise Erie’s Beaver River Project are located in the Towns of Croghan and Watson in Lewis County and in the Town of Webb in Herkimer County, New York.  Progressing downstream these are the Moshier (RM 29.9), Eagle (23.0), Soft Maple (RM 21.0), Effley (RM 16.9), Elmer (RM 16.2), Taylorville (RM 14.8), Belfort (RM 13.5) and High Falls (RM 11.0) developments.

Certification History

December 8, 2014: The Beaver River Hydroelectric Project (FERC No. 2645), LIHI Certificate No. 7 has been determined by the Executive Director, Michael J. Sale to satisfy the requirements of the Low Impact Hydropower Institute (LIHI) Certification Program. The decision to certify the Beaver River Hydroelectric Project is for a 5-year term, effective July 16, 2013 and expiring July 16, 2018.

November 18, 2013: The Low Impact Hydropower Institute has received an application for recertification of the Beaver River Project. The 2013 application was received on August 5, but due to administrative backlog, the certificate has been granted a six month extension beyond July 16, 2013 to allow for review of the application.

August 28, 2008: The Beaver River Project has been certified for a second five year term of low impact certification. The Board’s vote to recertify the project was unanimous, and the effective certification term is July 16, 2008, expiring July 16, 2013.

July 16, 2003: The Beaver River Hydroelectric Project has been certified as low impact for a five year term, effective July 24, 2003 and expiring July 24, 2008. It is the first hydropower facility in New York to earn LIHI certification.

March 20, 2003: Erie Boulevard Hydropower, LP has submitted an application for certification of the Beaver River Project. It is comprised of eight facilities operated and licensed together as one project.
