Info

A 30-inch-diameter ball valve is located 1n the powerhouse immediately upstream of the turbine to serve as a turbine shutoff valve. An 8-foot by 4-foot buri ed rei nforced concrete ta il race di scharges into four 3-foot by 3-foot concrete box culverts extending from the former Lower Powerhouse. These culverts, in turn, connect to a double 4-foot by 9-foot reinforced concrete box culvert that extends under Egan Drive and discharges into Gastineau Channel. The former Salmon Creek Lower Powerhouse is now used as a warehouse. 3.3 IMPOUNDMENT Salmon Creek Reservoir. Until recently Salmon Creek Reservoir had a normal maximum water surface elevation of 1172 feet (USCD), with a resulting gross storage capacity of 18,000 acre-feet and a surface area of 205 acres. However, as ordered by the FERC in the current Project license, the reservoir surface is not allowed to exceed E1 1140 (USCD) for safety considerations (see Dam Safety Report, included in the Supporting Design Document to Exhibit F)' At this elevation the gross storage capacity is 12,000 acre-feet and the reservo; r area is 165 acres. The usab 1 e storage ; s 11,890 acre-feet at th; s reduced level. The minimum pool elevation is 1019 feet (USCD). 3.4 TURBINE-GENERATORS Salmon Creek Upper Turbines. The Salmon Creek Upper Powerhouse contains two Joshua Hendy 2,500-horsepower, impulse turbines. They each operate at 257 rpm under an average net head of 685 feet. Salmon Creek Upper Generators. The two General Electric generators installed at the Upper Powerhouse are three-phase, 60 Hz, 1,750-kVA, 2,300-Volt synchronous generators. Excitation is provided by an automatic static voltage regulator system with a battery bank providing reliable control power. Salmon Creek Lower Turbine. The Lower Powerhouse contains a single, 9,210-horsepower Gilkes Turgo impulse turbine which operates at 720 rpm under a net effective head of 800 feet. Salmon Creek Lower Generator. The single generator installed at the Lower Powerhouse ;s a Siemans-Al1is three-phase, 10,500-kVA, 12,700-Volt synchronous generator. Excitation is provided by a rotating exciter directly coupled to the generator shaft. 3.5 PRIMARY TRANSMISSION LINES Salmon Creek Transmission Line. The Salmon Creek Component of the Project includes 2 miles of 23-kV transmission line, most of which connects the Upper Powerhouse and the old lower switchyard. The remaining short section of line runs from the new Lower Powerhouse to the new distribution substation. A-9
3.6 ADDITIONAL EQUIPMENT A-10 Salmon Creek Upper Powerhouse. The Upper Salmon Creek Powerhouse has six 600-kVA, single-phase, 2,300-23,000-Vo1t, oil-immersed, water-cooled General Electric transformers. Two sets of three 23,000-Vo1t, single throw disconnect switches are provided as line disconnects. Salmon Creek Lower Powerhouse. Transformers and breakers are not within the Project boundary. They are considered part of the distribution system. 3.7 LANDS OF THE UNITED STATES The Salmon Creek Component of the Project occupies 315 acres of 1 and owned by the Un i ted States. The Component is 1 oca ted wi th in the Juneau Townsite Boundary as shown in Exhibit G-1. These lands have been selected by the State of Alaska, but remain under the interim management of the Bureau of Land Management (BLM) until the adjudicative process for selection has been completed.
