k. Project Description:
Existing Project Facilities and Operation
The project is located at the existing 115-foot-high, 1,525-foot-
long Wrightsville Dam which is owned, operated, and maintained by the
state of Vermont for flood control but also contains facilities
utilized by WEC for hydropower generation. The licensed project
consists of the following constructed facilities: A 445-foot-long, 5-
foot-diameter steel aboveground penstock emerging from the base of the
dam that conveys water to a 1,320-square-foot partially-buried project
powerhouse containing three fixed blade turbines with rated capacities
of 96, 259, and 578-kilowatts (kW) for a total installed capacity of
933 kW; a 750 square-foot substation located adjacent to the powerhouse
that steps up the voltage from 4.16 kilovolts (kV) to 12.5 kV; a 450-
foot-long, 12.5-kV transmission line; and appurtenant facilities.
Water from Wrightsville Reservoir enters an existing non-project
intake structure at the dam containing two separate intake chambers: A
``hydropower bay'' located at an elevation of 631 feet and an overflow
bay located at an elevation of 635 feet. Water entering the hydropower
bay passes through trashracks, a headgate, and non-project conveyance
tunnel within the dam and is conveyed to the powerhouse through the
project penstock before re-entering the North Branch Winooski River
approximately 400 feet downstream of the dam creating a 400-foot
bypassed reach. Water entering the overflow bay passes
[[Page 73697]]
through trashracks and an overflow tunnel within the dam before being
discharged to the bypassed reach through a low-level outlet at the base
of the dam. WEC's three turbines located in the powerhouse cannot be
throttled; however, WEC operates its turbines in a specific sequence to
operate in near run-of-river mode while maintaining reservoir
elevations between 633 and 635 feet from September 1 through May 31 and
between 634 and 635 feet from June 1 through August 31. Additionally,
WEC maintains minimum flows of 3.4 cubic feet per second (cfs) in the
bypassed reach and 25 cfs in the North Branch Winooski River downstream
of the powerhouse.
Proposed Project Facilities and Operation
WEC proposes to bring the following existing facilities into the
project boundary as project structures: the trash racks with one-inch
spacing and the 9.5-foot by 6.5-foot headgate located within the non-
project hydropower bay at the intake; the 1.3-foot by 1.5-foot
automated minimum flow gate located at the base of the wall separating
the two intake chambers used to pass minimum flows to the bypassed
reach; the 100 square-foot hydraulic house located within the dam
housing a hydraulic pump and controls used to operate the project
headgate and minimum flow gate; and the 550-foot-long dirt road used to
access the intake structure.
WEC would continue to operate its three turbine units to replicate
near run-of-river operations and continue to maintain its existing
minimum flows both within the bypassed reach (i.e., 3.4 cfs) and
downstream of the powerhouse (i.e., 25 cfs). However, WEC proposes to
modify operations by using its minimum flow gate to release more flow
into the bypassed reach (up to 25 cfs) as generating units are turned
on and off to reduce flow fluctuations downstream of the powerhouse.
WEC also proposes to maintain the reservoir between an elevation of 634
and 635 feet year-round (rather than operating between 633-635 feet)
and would cease all generation when reservoir levels fall below 634
feet.
