c. Date Filed: February 27, 2025.
d. Applicant: Green Mountain Power Corporation (GMP).
e. Name of Project: Glen Hydroelectric Project (project).

i. FERC Contact: Steve Kartalia at (202) 502-6131, or stephen.kartalia@ferc.gov.
j. The application is not ready for environmental analysis at this time.
k. The existing Glen Project consists of a 173-foot-long, 14-foot-high concrete gravity dam that includes the following sections: (1) a 5-foot-long south abutment section; (2) a 123-foot-long, 12-foot-high spillway section equipped with: (a) 3-foot-high flashboards with a crest elevation of 413.2 feet National Geodetic Vertical Datum of 1929 (NGVD 29) at the top of the flashboards; (b) a 1-foot-wide concrete pier; (c) a trash sluice; and (d) a 4-foot-diameter, 14-foot-long steel pipe that extends downstream from the trash sluice; and (3) a 45-foot-long north abutment section. The dam creates an impoundment with a surface area of approximately 7 acres at an elevation of 413.2 feet NGVD 29. The project also comprises a (1) a 53.5-foot-long, 58.5-foot-wide intake structure that includes: (a) two 8-foot-wide, 8-foot-high steel headgates equipped with a 20-foot-wide, 15-foot-high trashrack with 2-inch clear bar spacing; and (b) a 10-foot-long steel inlet transition pipe from an 11-foot-wide, 6-foot-high rectangular cross-section to an 8.5-foot-diameter cross-section that connects the intake to a penstock; (2) a 4,100-foot-long, 8- to 8.5-foot-diameter penstock that trifurcates into three 4-foot-diameter sections that connect to the powerhouse; (3) a 20-inch minimum flow pipe protruding from the penstock immediately downstream of the intake structure; (4) a 26-foot-long, 30-foot-wide powerhouse containing a 685-kilowatt (kW) regulated propeller bulb turbine-generator unit and two 400-kW fixed propeller bulb turbine-generator units for a total installed capacity of 1,485 kW; (5) an approximately 34-foot-long, 30-foot-wide, 8-foot-deep tailrace that discharges into the Mascoma River; (6) a 50-foot-long underground transmission line that leads to a 2.4/13.2-kilovolt step-up transformer where the project is connected to the local electric grid; and (7) appurtenant facilities. The project creates an approximately 4,300-foot-long bypassed reach of the Mascoma River.
The current license requires GMP to operate the project in "instantaneous" run-of-river mode, so that project outflow approximates inflow to the impoundment. The current license also requires that GMP release a continuous minimum flow of 40 cubic feet per second (cfs) or inflow to the impoundment, whichever is less, from the project to the bypassed reach, as measured immediately downstream from the project dam, to protect aquatic resources in the Mascoma River. GMP releases the minimum flow to the bypassed reach through the minimum flow pipe. The average annual generation of the project between 2012 through 2024 was approximately 2,782 megawatt-hours.
GMP propose to: (1) continue operating the project in a run-of-river mode; (2) continue releasing a continuous minimum flow of 40 cfs or inflow to the impoundment, whichever is less, from the project to the bypassed reach; (3) develop an operations compliance monitoring plan; (4) avoid tree removal of all trees greater than 3 inches in diameter at breast height on project lands from April 15 through October 31, to minimize potential impacts to northern long-eared and tricolored bats; and (5) develop an historic properties management plan.
