The power plant
is a Reservoir based scheme on river Ramganga
located near the famous Jim Corbet Park in
district Pauri Garwhal
and utilizes the water dammed up for irrigation purpose. The project
was commissioned in 1975. The water in the irrigation channel is
regulated by UP Irrigation and the generation is dependent on the rain
in the catchment area as also on the drawal of water for irrigation purpose in the
command area of the canal. The surface power house is located at the
toe of the dam and houses 3 units of 66 MW each with Francis turbines
of 92400 HP. The Power Station's Design Energy is 311 MU with a design
head of 84.4 m.
 The Ramganga power
station is a medium head scheme with a design discharge of 285 cum. The
project has unique challenges in operation due to restriction imposed
on the release of water in the water conductor system by UP irrigation
which is dependent on the demand of water in the command area of the
canal based on the irrigation requirement. The generation in the plant
takes place after the monsoon season when the demand for irrigation
picks up.
The generation from the plant is dependent on the drawal
of water for irrigation in the downstream of the plant and rainfall in
the catchment area.
The repair of the downstream channel is with UP- Irrigation Department.
UJVNL has taken up the repairs of the under water parts of the plant.
UJVNL proposes to carry out the M&U of the power station which is estimated
to cost Rs. 36.95 crore.
The major M&U works proposed are:-
i) Provision of Micro-processor
based Governors, Static excitation equipments, On-line monitoring
equipment and Replacement of Generator winding with F Class insulation.
ii) Modernization of Communication, Test & Control,
Protection & Instrumentation, switchyard equipment, hydro
mechanical equipment, etc.
iii) Repair of civil structures and MIV
iv) Improvement in the efficiency of Generators and Turbines
The generation after the completion of M&U works would increase to
315 MU and the works are expected to be completed by 2010-11.
