GENERATION AND TRANSMISSION SYSTEM
BBMB’s hydro power stations are sources of
cheap electrical energy, which also provide
scarce peaking power and assistance in case
of a contingency to Northern Grid. BBMB
machines also help in primary regulation of
frequency of Northern Grid.
During 2003-2004 the generation from the BBMB
Power Houses has been 11,441 MU against the
target of 9650 MU laid down by CEA,
Government of India. BBMS achieved an all time
high peak generation of 2861 MW in the year
2003-04. The plant availability of BBMB Power
Stations during 2003-04 has been 88.77%. All
the machines at Bhakra Left and Right Power
Houses and Pong Power House with installed
capacity of over 1700 MW were put on free
governor operation w.e.f October, 2003 to help
in regulation of frequency of the Northern
Regional Grid.
The power generation at BBMB Power stations
is being evacuated through BBMB Power
evacuation system running into 3735 ckt km.
length of 400KV, 220KV, 132KV and 66KV
transmission lines and 24 EHV Sub-stations.
The BBMB Power evacuation system operates
in an integrated manner in the Northern grid
with its transmission network spreading over the
States of Himachal Pradesh, Punjab, Haryana
and Delhi. The system is interconnected with
transmission system of POWERGRID and the
States of Uttar Pradesh, Rajasthan and Delhi.
The availability of transmission system during
the year 2003-04 has been 98.32%.
IRRIGATION
At the time of partition of India, about 80% of
the irrigated area of Punjab went to West
Pakistan leaving India with very meagre irrigation
resources. The mighty Bhakra-Nangal and Beas
Projects changed the scenario and turned
Northern India into granary of the Nation.
The Bhakra-Nangal and Beas Projects have not
only brought Green Revolution to the States of
Punjab, Haryana and Rajasthan, but also White
Revolution by way of record production of milk
and Industrial Revolution by way of providing
cheap electrical energy. The States of Punjab,
Haryana and Rajasthan are being supplied
average about 34537 million cubic metres of
water per year from Satluj , Ravi and Beas rivers
which irrigates 1 crore 20 lac acres of land.
RENOVATION. MODERNISATION AND
UPRATING (RM&U)
All the five units of Bhakra Right Bank Power
Houses, which were commissioned during the
year 1966 to 1968, have been uprated from
original capacity of 120MW to 157MW each.
The RM&U of two units each at Ganguwal and
Kotia Power Houses has already been
completed. RM&U of all the six units of 60 MW
to 66 MW of Pong Power House has already
been completed which has resulted in additional
capacity of 36 MW increasing the installed
capacity from 360 MW to 396 MW.
BBMB plans to undertake the RM & U works of
Bhakra Left Bank Power House machines
(5x108 MW) which are in operation for a period
of about 40 years. All the five units are proposed
to be uprated from 108 MW to 126 MW each.
The R M & U of Bhakra Left Bank Power House
is expected to provide additional capacity of 90
MW to the system and is expected to generate
additional 88 MU annually due to improved
efficiency. This work shall be carried out in Xth
and Xlth plans. The capacity addition is expected
to be 18 MW during Xth Plan and 72 MW during
XI Plan.
One unit each of Ganguwal and Kotia Power
Houses which were supplied by M/S Hitachi,
Japan, have been planned for RM&U. With the
proposed RM&U of one machine each at
Ganguwal and Kotia Power Houses, the derated
capacity of the machines shall be uprated by
4.44 MW which will result in additional annual
generation of 36 MU. During renovation,
replacement of major components like runner,
governor, stator, unit transformer and other
associated equipment is envisaged. The work
on this scheme is proposed to be undertaken
during Xth Plan and is expected to be completed
in the year 2006-07.
The RM&U work on the old Power Houses has
given new lease of life to the machines and is a
significant step towards meeting the aspirations
of the Nation for adding low cost peaking power
to the system through Renovation, Modernization
& Uprating of old power plants as per the
National Hydro Policy.
UPKEEP OF DAMS AND HYDEL CHANNELS
The upkeep of Dams and Hydel Channels by
BBMB has been of high standards, which are
considered as benchmarks for other hydro
projects in the region. Monitoring of the health
and behaviour of dams with the help of
instruments installed in and around the body of
the dams shows the normal behaviour. Under
water inspections of dams also do not indicate
any abnormality.
Nangal Hydel Channel is running continuously
since its year of commissioning i.e. 1954.
Inspection, repair and maintenance of Nangal
