The Federal Energy Regulatory Commission on Oct. 1 granted a three-year preliminary permit to Siting Renewables LLC so it can study the feasibility, without a competing application being filed, of the proposed Chain Dam Hydroelectric Project.
This project is to be located on the Lehigh River near the City of Easton in Northampton County, Pennsylvania. The estimated annual generation of the proposed project would be 7,880,000 kilowatt-hours.
The project would consist of: an existing 20-foot-high concrete gravity dam with a spillway; an existing impoundment having a surface area of about 300 acres and a storage capacity of 1,200 acre-feet at an elevation of 190 feet mean sea level (msl); three new intake channels, each with a very low head (VLH) 500-kW turbine-generator unit, with a maximum generating capacity of 1,500 kW, with a maximum hydraulic capacity of 2,300 cubic feet per second under a net head of 13.5 feet; three new, heavy flotsam trash racks; a new crest-mounted walkway carrying hydraulic and electrical conduits from the VLH turbines to a new powerhouse; and a new 280-foot-long, 12.42/7.2 kV primary transmission line.
The FERC order noted: “During the course of the permit, the Commission expects that the permittee will carry out prefiling consultation and study development leading to the possible development of a license application.”
