k. The Project Description: The Conowingo Project consists of a
concrete gravity dam with a maximum height of approximately 94 feet.
The dam consists of a 1,225-foot-long non-overflow gravity section, a
2,385-foot-long ogee shaped spillway section, a 950-foot-long intake-
powerhouse section, and a 100-foot-long non-overflow gravity section.
The spillway consists of a 2,250-foot-long section with a crest
elevation of 86.0 feet, and a 135-foot-long section with a crest
elevation of 98.5 feet. The spillway is fitted with 50 Stoney-type
crest gates and two regulating gates. Each Stoney crest gate is 22.5
feet high by 38 feet wide and has a discharge capacity of 16,000 cubic
feet per second (cfs) at a reservoir elevation of 109.2 feet. The two
regulating gates are 10 feet high by 38 feet wide and have a discharge
capacity of 4,000 cfs per gate at a reservoir elevation of 109.2 feet.
Conowingo dam impounds the Susquehanna River, forming Conowingo
reservoir (Conowingo pond) that extends 14 miles upstream from the dam.
Total storage in the 9,000-acre reservoir is approximately 310,000
acre-feet, and total useable storage is about 71,000 acre-feet at the
normal full pool elevation of 109.2 feet. The elevation of the normal
river surface below the dam is approximately 20.5 feet. The impoundment
provides approximately 89 feet of gross head for power generation
purposes.
The power plant is integral with the dam and is composed of 13
turbine-generator units, draft tubes, and transformer bays. The first
seven turbine-generating units (1-7) are completely enclosed within the
powerhouse, and the last four units (8-11) are located outside. The
hydraulic equipment for units 1-7 consists of Francis-type single
runner hydraulic turbines. The hydraulic equipment for units 8-11
consists of four mixed-flow Kaplan-type hydraulic turbines. Units 1, 3,
4, 6 and 7 have 47.7-MW generators; Units 2 and 5 have 36.0-MW
generators; and Units 8-11 have 65.6-MW generators. Additionally, two
house turbines provide station service and ``black-start'' capability
with each unit having a 1.6-MW generator. Water flowing through the
turbines is discharged via the draft tubes into the tailrace
immediately downstream of the dam.
Electricity generated at the project is transmitted by two
individual 220-kilovolt (kV) transmission lines extending from the
project substation to East Nottingham.
The Conowingo Project has an authorized nameplate generating
capacity of 573 MW and generates an average of 1,836,125 MWh annually.
Exelon is not proposing any new or upgraded facilities or structural
changes to the project at this time. Also, Exelon has engaged
interested stakeholders to participate in the development of a
comprehensive settlement agreement based on collaborative negotiation
of specific terms and conditions for the new Conowingo license.
