The Federal Energy Regulatory Commission on Jan. 11 granted an August 2015 application from Empire State Hydro 301 LLC for a preliminary permit to study the feasibility of the proposed Diamond Mills Hydroelectric Project, to be located at the existing Diamond Mills Dam on Esopus Creek in Saugerties, Ulster County, New York.
The proposed project would consist of: an 140-acre impoundment with a normal volume of 826 acre-feet; an existing 350-foot-long, 32-foot-high concrete gravity dam with a spillway length of 340 feet; an existing 30-foot-long, 9-foot-high auxiliary spillway; an existing 10-foot-long, 6-foot-diameter penstock; two new 750-kW turbines; a new 50-foot-long, 30-foot-wide powerhouse; and a new 300-foot-long, 12.7-kV transmission line. The estimated annual generation would be 5,300 megawatt-hours.
During the course of the three-year permit, the commission expects that the permittee will carry out prefiling consultation and study development leading to the possible development of a license application.
