Daily Rules, Proposed Rules, and Notices of the Federal Government
Take notice that the following hydroelectric application has been filed with the Commission and is available for public inspection.
j. This application is not ready for environmental analysis at this time.
York Haven's main dam and east channel dam impound the Susquehanna River, forming Lake Frederic that extends 3.5 miles upstream from the dam. Total storage in the 1,849-acre reservoir is approximately 8,000 acre-feet, and total useable storage is approximately 1,980 acre-feet. The current FERC license allows a 1.1-foot fluctuation in the project impoundment, but is not used under normal run-of-river operation. The normal water surface elevation of the project impoundment is 276.5 feet. The elevation of the normal river surface below the dam is approximately 251.40 feet. The impoundment provides approximately 22.5 feet of net head for power generation purposes.
The brick and stone masonry powerhouse has approximate dimensions of 470 feet by 48 feet and is located at the southern end of the headrace wall and at the eastern end of the forebay bulkhead wall. The powerhouse includes 20 turbine-generator units and appurtenant equipment. The hydraulic equipment for units 1-3 are vertical-shaft, fixed-blade, Kaplan turbines; unit 4 is a vertical-shaft, manually adjustable blade, Kaplan turbine; units 5 and 6 are vertical-shaft, fixed-blade, propeller-type turbines; units 7, 8, 10-13, and 15-20 each consist of two vertical-shaft, Francis turbines connected through bevel gears to a single horizontal shaft; unit 9 is a two vertical-shaft, Francis turbine connected through a gearbox to a single horizontal shaft; and unit 14 is a vertical-shaft, Francis turbine. Units 1-5 have 1.6-MW generators; unit 6 has a 1.32-MW generator; unit 14 has a 1.2-MW generator; and units 7-13 and 15-20 have 0.7-MW generators. Water flowing through the turbines is discharged into the tailrace immediately downstream of the dam.
Electricity generated at the project is transmitted by 115-kilovolt (kV) transmission lines extending from the project substation to the grid.
The York Haven Project has an authorized nameplate generating capacity of 19.65 MW and generates an average of 130,812 MWh annually. York Haven Power is currently studying the feasibility of providing a nature-like fishway to enhance fish passage facilities at the project.
