May 1, 2019: The Low Impact Hydropower Institute has received a complete application for Low Impact Certification of the Yaleville Hydroelectric Project. LIHI is seeking public comment on this application. Specifically, we are interested in knowing whether you think the Project meets the LIHI Low Impact Certification Criteria, as revised in the 2nd Edition Handbook. Please review the program and criteria in LIHI’s revised Handbook and then review the Project’s application materials below.
Comments that are directly tied to specific LIHI criteria (flows, water quality, fish passage, etc.) will be most helpful, but all comments will be considered. Comments may be submitted to the Institute by e-mail at firstname.lastname@example.org with “Yaleville Project Comments” in the subject line, or by mail addressed to the Low Impact Hydropower Institute, 329 Massachusetts Avenue, Suite 6, Lexington, MA 02420. Comments must be received on or before 5 pm Eastern time on June 30, 2019 to be considered. All comments will be posted to the web site and the applicant will have an opportunity to respond. Any response will also be posted.
The Yaleville Hydroelectric Project is located at river mile 88.5 on the Raquette River near the Town of Yaleville in Franklin and St. Lawrence Counties in New York. The Project was originally constructed in 1903 with a new powerhouse constructed in 1922. The Project is owned by Erie Boulevard Hydropower, LLC (Brookfield Renewable Energy Group). Upstream of the Project numerous hydroelectric developments, including the Upper Raquette River (LIHI #14A) and Middle Raquette River (LIHI #14B). The Yaleville Project sits between the Norwood and East Norfolk developments of the Lower Raquette River (LIHI #14C).
On October 11, 2017 FERC issued an Order extending the current license expiration date from January 31, 2022 to December 31, 2033 in order to align with the other Erie-owned projects on the Raquette River having license expiration dates in that timeframe.
The Project consists of the Yaleville dam which includes a concrete gravity overflow dam about 170 feet long and 13 feet high, with 2-foot-high flashboards at the crest; a concrete gravity flood gate structure, 49 feet long and composed of two stop log gates 15 feet long and 10 feet high, and one electrically operated lift gate for water surface control, about 11 feet long by 10 feet high.
|Owner||Brookfield Renewable Energy Group|
|Location||River Mile 25.5 on the Raquette River|
|Installed Capacity||0.7 MW|
|Average Annual Generation||3,800 MWh|
|Facility Type||Run of river|
The dam impounds a 95-acre reservoir that extends approximately 1.8 miles upstream. A bypassed reach, approximately 485 feet long is created by the Project. Water is conveyed to the intake via a forebay (canal) that is 60 feet wide and 275 feet long. The intake structure is integral to the upstream side of the powerhouse. The powerhouse contains two vertical Francis units with a total installed capacity of 0.7 MW.
The Project is operated in a run‐of‐river mode. In addition, 36 cfs are provided through a rectangular weir and 3-foot deep plunge pool located at the downstream end of the forebay to flume to support downstream passage. The fishway operates each year from on or about May 15 (after spring run-off and after flashboards have been reinstalled) until approximately November 1.
