MoP - Ministry of Power

New Delhi Municipal Council (NDMC) has awarded
consultancy work for Turnkey execution of System
Strengthening Works in NDMC areas at a project cost
of Rs. 200 Crore. The Project includes construction of
new 66/11kV & 33/11 kV GIS stations, augmentation
of existing stations, U/G cabling works etc. with time
schedule of 30 months.
Meghalaya State Electricity Board (MeSEB) has
awarded consultancy work for Turnkey execution of
220 kV D/C line from Misa to Byrnihat alongwith 2x160
MVA, 220/132 kV New Sub-station at Byrnihat and
associated Bay extension works at 220 kV Misa
POWERGRID Sub-station on cost plus basis.
Estimated project cost is: Rs.150 Crore.
An Agreement has been signed with M/s JPL (JAYPEE
POWERGRID LIMITED) for Engineering Consultancy
for complete design, drawing, engineering (including
post award) for Transmission Lines associated with
1000 MW Karcham Wangtoo HEP.
22.3UNIFIED LOAD DESPATCH & COMMUNICATION
FACILITIES
The unified approach for planning, engineering, procuring,
and implementing the Load Despatch and dedicated
Communication system is paying rich dividend in the form
of timely completion of projects and enhancing in-house
capability of handling these complex and gigantic schemes.
Planned rapid expansion of regional grids and their
integration to form National Grid poses great challenges in
Grid Operation & Management. Modernization of Regional
Load Despatch Centres along with State/ Sub-State Load
Despatch Centres and dedicated communication schemes
in all the regions Northern, Southern, North-Eastern, Eastern
and Western Regions have been successfully completed.
These centres have become epitome of technological
excellence in grid operation through three tier hierarchical
system, a unique feature in grid operation in the world. These
are world’s one of the largest and most complex projects.
These complex projects involving the state-of-the-art
technology have resulted in real time monitoring and control
of the grid to enhance safety, security, reliability and stability
in all regions of the country. These facilities minimize grid
disturbance/failure and facilitate quick grid restoration, in
case of failure.
22.4 RESEARCH & DEVELOPMENT
POWERGRID is constantly striving to excel in its
technological leadership which is essential for sustainable
business growth and to maintain competitive edge over
others in national and international market. The organization
through its technological leadership is catering to diverse
geographical climatic and terrain conditions utilizing existing
transmission infrastructure along with creating new
transmission capacities in a cost effective manner. Towards
technological advancement, POWERGRID has established
several fully automated remote controlled 400 kV substation
like Bhiwadi, Kolar, Gajuwaka, Chandrapur etc. Many more
sub-stations are being planned on similar lines with a view
to optimise upon operational costs.
POWERGRID has also introduced ‘INVAR’ power
conductors, which can sustain high temperature upto 200ºC
against the normal 85ºC. This can wheel electric power more
than two times the normal line. POWERGRID is also using
Thyristor Controlled Series Compensation (TCSC) and
uprating/ upgradation of lines, etc. to enhance power carrying
capacity of existing lines. Further, in order to conserve the
precious Right of Way, width of 765 kV transmission towers
has been reduced from usual 85 mtrs. to 64 meters for the
first time in the world. Further, at selected location the tower
height was raised to 75 mtrs., which makes it taller than the
Qutab Minar, to save precious forests and protect wildlife.
POWERGRID commissioned 400kV Gas Insulated
Substation (GIS), first time in the country at Maharani Bagh
New Delhi, which reduces 75% land requirement over
conventional EHV Air Insulated substation. Besides, 765kV
Single Circuit Sipat–Seoni transmission line was
commissioned to evacuate bulk power from pit head power
station at Sipat, which is first time at 765 kV level, operating
in the country
POWERGRID envisages establishing a “Centre for Power
Transmission Research and Application” which shall
supplement the facilities of existing Research Institutions
and provide opportunities for applied research in power
transmission sector. POWERGRID has also constituted an
advisory body consisting of eminent experts from power
utilities, research and academic institutions and consultants
from India as well as from Canada, USA, and Brazil to
facilitate adoption of latest technologies for construction,
monitoring and maintenance of transmission system suiting
Indian conditions.
22.5 E-GOVERNANCE
POWERGRID is systematically developing competency to
deploy Information Technology for efficient and effective
discharge of its functions. Some of the salient achievements
are Web based Enterprise wide Information Portal as a step
towards E-Governance, State-of-the-Art Multi Locational
Video Conferencing System, Inspection Management
System on internet based B2B platform, Engineering Project
management system developed in-house, Enterprise wide
Converged IT and Communication System, Establishment
of state-of-the-art 1200 node IT network infrastructure at its
Gurgaon office complex with innovative features like Wi-Fi.
POWERGRID has also initiated action for implementation
of ERP.
