l. The existing Helms Pumped Storage Project (project) includes: (1) a 132-foot-long, by 89-foot-wide, by 58.5-foot-high concrete intake-discharge structure (Courtright Intake-Discharge Structure), with metal trash racks, in Courtright Lake; (2) one 4,243-foot-long tunnel (Tunnel 1) composed of two sections: (a) a 3,312-foot-long, 27-foot-diameter concrete-lined section; and (b) a 931-foot-long, 22-foot-diameter steel-lined section; (3) a 32.5-foot-long, by 38-foot-wide, by 45-foot-high gatehouse; (4) a 206-foot-long, 22-foot-diameter, above-ground steel pipe that connects Tunnel 1 and Tunnel 2; (5) one 9,016-foot-long tunnel (Tunnel 2) composed of two sections: (a) a 764-foot-long, 22-foot-diameter steel-lined section; and (b) a 8,252-foot-long, 27-foot-diameter concrete-lined section; (6) a 600-foot-long adit of an unknown diameter, with an adit plug with frame and gate; (7) a 535-foot-high, vertical shaft surge chamber for Tunnel 2 with a 47-foot-diameter lower section and 60-foot-diameter upper section, with 12 feet of the chamber exposed above grade; (8) a 2,205-foot-long penstock composed of three sections: (a) a 1,070-foot-long, 27-foot-diameter concrete-lined section; (b) a 300-foot-long, 27-foot-diameter concrete-lined section; and (c) a 330-foot-long, 27-foot-diameter concrete-lined manifold section, that branches into three, 505-foot-long steel-lined penstocks, that reduce in diameter from 15.5 feet to 11.5 feet, to 10.5 feet until connecting to the turbine-generator; (9) a 336-foot-long, by 83-foot-wide, by 125-foot-high excavated rock chamber underground powerhouse that includes three, 360-megawatt (MW) vertical Francis-type pump-turbine units, for a total installed capacity of 1,080 MW, and three, vertical indoor generators with an approximate total nameplate capacity of 1,212 MW; (10) a 3,727-foot-long, 27-foot-diameter concrete-lined tunnel (Tunnel 3); (11) a 984-foot-tall, vertical shaft surge chamber for Tunnel 3 with a 27-foot-diameter lower section and a 44-foot-diameter upper section that transitions into a 10-foot-diameter air shaft topped by a 10-foot-tall, 14-foot-diameter protective device above grade; (12) an 88-foot-long, by 78-foot-wide, by 51-foot-high concrete intake-discharge structure (Wishon Intake-Discharge Structure), with metal trash racks, in Lake Wishon; (13) a 220-foot by 265-foot above ground, fenced switchyard; (14) an underground transformer bank of 10 transformers with a capacity of 150,000 kilo-volt-amperes each; (15) a 3,723-foot-long, 30-foot-wide, 25-foot-high powerhouse access tunnel; and (16) appurtenant facilities.
Although the project facilities do not include any dam or reservoir, PG&E operates the project for power generation using Courtright Lake (upper reservoir) and Lake Wishon (lower reservoir), impounded by Courtright Dam and Wishon Dam, respectively, which are licensed project facilities of the Hass-Kings River Hydroelectric Project (Project No. P-1988). Courtright Lake has a usable storage area of approximately 123,184 acre-feet and normal maximum and minimum water surface elevations of 8,184 feet and 8,050 feet, respectively. Lake Wishon has a usable storage area of approximately 128,606 acre-feet and normal maximum and minimum water surface elevations of 6,550 feet and 6,428.9 feet, respectively. To generate power, water is released from Courtright Lake through the Courtright Intake-Discharge Structure, Tunnel 1, Tunnel 2, and the penstock, into the powerhouse and is discharged through Tunnel 3 and the Wishon Intake-Discharge Structure into Lake Wishon. During periods of low energy demand, water is pumped through these project facilities in reverse ( i.e., from Lake Wishon to Courtright Lake). The average annual generation (2015 to 2020) was 736.6 gigawatt-hours.
The project generators are connected to the regional electric grid by: (1) an underground transformer bank of 10 transformers with a capacity of 150,000 kilo-volt-amperes each; (2) a 220-foot by- 265-foot above ground, fenced switchyard; and (3) a 60.7-mile-long, double-circuit 230-kilovolt (kV) transmission line that connects the Helms switchyard to PG&E's interconnection point with the grid at the non-project Gregg Substation. The project also includes an approximately 1.8-mile-long, 21-kV distribution line from the non-project Woodchuck Substation to the Helms Headquarters and Helms Powerhouse and an approximately 2-mile-long, 21-kV distribution line from the non-project Woodchuck Substation to the Helms Support Facility and non-project Wishon Village Recreational Vehicle Park.
[top] The project also includes: (1) the Helms Headquarters facility with ancillary facilities; (2) the Helms Support Facility with ancillary facilities; (3) project recreation facilities including the: (a) Courtright Boat Launch; (b) Trapper Springs Campground; (c) Marmot Rock Campground; (d) Wee-Mee-Kute Fishing Access; (e) Wishon Boat Launch; (f) Lily Pad Campground; (g) Upper Kings River Group Campground; (h) Wishon Dam Fishing Access; (i) Short Hair Creek Fishing Access; (j) Coolidge Meadow Fishing Access; (k) Helms Picnic Area; (l) Upper Kings River Fishing Access,
