The power station is a Run-of-River scheme on river Ganga located upstream of the holy city of Hardwar and was commissioned in 1980-1981.There are
4 Kaplan vertical shaft turbines, Maximum operating head 32.5m Annual
generation of the present design is about 725 MU which may increase to
about 1076 MU due to the enhanced hydrological regulation in upper basins
owing to commissioning of Tehri Project as
well as upgrading works per current modern practice. For these reasons
the time is being considered appropriate to undertake upgrading works
so as to ensure the secure and reliable operation of the power station
for the next 20-25 years.
UJVNL proposes to carry out the M&U of the power station which
is estimated to cost Rs. 250.00 crore. The objective of the M&U program is to
rehabilitate and upgrade the project to ensure dependable future
generation and increase the station output to the highest economic
level, keeping in view the following:
i) Rehabilitate and modernize
the Chilla power station.
ii) Increase the Plant output, preferably by increasing the unit
discharge and output.
iii) Provide hydraulic equipment that will be more resistant
against erosion.
iv) Provide new turbine runner with an improved cavitations
behavior.
v) Provide automatic trash rack cleaning machine.
The generation after the completion of M&U works would
increase to 1076 MU and the works are expected to be completed by
2011-12.
