New York

The Hoosic River Project is located in upstate New York northeast of Albany and Troy. The project consists of two developments licensed as FERC Project 2616. In the most recent recertification application on March 31, 2014, EBH states that the total project has an installed capacity of 18.5 MW and produces an average annual generation (AAE) of 83.00 GWh (Plant factor of 51.2%). Both developments operate in a peaking mode.

Project Name Hoosic River
LIHI Certificate Number 13
LIHI Effective and
Expiration Dates
July 9, 2014
July 9, 2019
Owner Brookfield Renewable Energy Group
State New York
Location Located on the Hoosic River in upstate New York, northeast of Albany and Troy.
Installed Capacity Total: 18.5 MW
Johnsonville: 2.1 MW
Schaghticoke: 16.4 MW
Average Annual Generation 83,000 MWh
Facility Type Peaking
FERC No. 2616

Project operations follow the flow requirements and reservoir target elevations as defined in the FERC License which requires a continuous year-round base flow below Schaghticoke and base flows below both developments while operating within daily reservoir fluctuation limits.

Johnsonville Development

The Johnsonville Development has a total catchment of 606 square miles and consists of:

  • a 39-foot-high, 529-foot-long concrete gravity dam topped with 2.5-foot-high wooden flashboards;
  • a reservoir with a 450-acre surface area and gross storage of 6,430 acre-feet;
  • a sluice gate;
  • a forebay structure;
  • an intake structure equipped with 1-inch clear-spaced vertical trashracks;
  • a powerhouse immediately adjacent to the dam containing two turbine generators with a total installed capacity of 2.1 megawatts (MW).

Schaghticoke Development 

The Schaghticoke Development has a total catchment of 619 square miles and consists of:

  • a 28-foot-high, 700-foot- long concrete gravity dam topped with 2.5 foot-high wooden flashboards and a pneumatic gate section9;
  • a reservoir with a 150-acre surface area and gross storage of 1,150 acre-feet;
  • a 2,300 foot-long open canal;
  • a set of forebay intake gates;
  • a forebay;
  • a pipeline intake equipped with 0-inch clear-spaced vertical  trashracks;
  • an 820 foot-long, 12.5- foot-diameter steel pipeline. This pipeline directs water from the forebay downward to the bypassed reach. It passes over the bypassed reach by the means of a support bridge, then heads up the other side of the river overbank to a surge tank;
  • a surge tank;
  • five penstocks directing water from the surge tank to the powerhouse;
  • a powerhouse containing four turbine generators with a total installed capacity of 16.4 MW. The canal, forebay, pipeline, and penstocks create a two-mile bypassed reach between the dam and the powerhouse.

Certification History

February 20, 2015 – The Hoosic River Hydroelectric Project (FERC No. 2616), LIHI Certificate No. 13 has been determined by the Executive Director, Michael J. Sale to satisfy the requirements of the Low Impact Hydropower Institute (LIHI) Certification Program. The Hoosic River Project is located on the Hoosic River in upstate New York, northeast of Albany and Troy.

In rendering this Certification, the Institute’s Executive Director used authority delegated by the LIHI Governing Board and the unanimous recommendation by the LIHI Governing Board Technical Committee resulting from a full review of the Application Reviewer’s report and all public comments and additional materials provided by the Applicant.  The decision to certify the Hoosic River Hydroelectric Project is for a 5-year term, effective July 9, 2014 and expiring July 9, 2019, with the following condition:

“The potential for ice buildup in the head pond stilling well and the hydraulic controls of the pneumatic gate on the Schaghticoke spillway is a recurring issue at the Hoosic River facility. Therefore, one new condition is added to the LIHI certificate:

Condition 1.  The facility owner shall develop a proactive procedure that can be followed during the winter season to prevent ice buildup problems at their facilities and to reduce the occurrence of water level or flow violations that have been evident in the past. A final report documenting the improved operating procedures will be provided to LIHI along with the first annual compliance letter following recertification. If similar violations of water level or flow requirements occur in future years, they shall be reported in the annual compliance letters to LIHI.  These annual reports shall contain copies of any pertinent correspondence and documents, as well as a description of any corrective actions taken.

April 17, 2014: The Low Impact Hydropower Institute received an application for a third term of certification of the Hoosic River Project. The current certificate term is scheduled to expire on July 9, 2014.

April 15, 2010: The Hoosic River Project has been certified for a second five year term of low impact certification, effective July 9, 2009 and expiring July 9, 2014.

October 21, 2004: The Hoosic River Project has been certified as low impact for a five year term, effective July 9, 2004 and expiring July 9, 2009.
