FERC issues preliminary permit for 9-MW Brownville Hydroelectric Project

The Federal Energy Regulatory Commission has issued a preliminary permit to Paddy Hill Holdings LLC to study the feasibility of the 9-MW Brownville Hydroelectric Project in Jefferson County, New York.

The proposed Brownville project, on the Black River, would consist of a new impoundment with a storage capacity of 500 acre-feet at a normal pool level of 284 feet mean see level, a  new concrete gravity dam 178 feet long by 22 feet high with an ogee crest spillway and 2 feet of adjustable crest gates or flashboards, a 10-foot-long by 8-foot-wide fishway, a powerhouse containing two turbine-generator units, and a new 4.16-kV underground transmission line 200 feet long connecting to an existing National Grid substation.

The project would have an estimated average annual generation of 43,000 MWh.

Paddy Hill holdings filed the application in December 2019. The preliminary permit is effective June 1, 2020, and lasts for 48 months.

The purpose of a preliminary permit is to preserve the right of the permit holder to have the first priority in applying for a license for the project that is being studied.
