  Home About UsCompany Profile Towards National Grid | | | | | | The objective of Power Grid Corporation of India Ltd is to create a strong and vibrant National Grid in the country to ensure the optimum utilization of generating resources, conservation of an eco-sensitive right of way and the flexibility to accommodate the uncertainty of generation plans.With the modernisation of RLDCs and implementation of various inter-regional links, inter-regional power exchange has grown manifold. During FY 2007-08, about 43,000 MUs of inter-regional energy transfer was facilitated--an increase of about 13% compared to the previous year (about 38,000 MU). Growth of inter-regional power exchange has helped in meeting more demand in energy deficit regions besides achieving overall economy. Inter-regional power transfer capacity of the National Grid has been enhanced to about 17,000 MW in FY 2007-08. Four major power regions of the country namely, North-Eastern, Eastern, Western and Northern are now operating as one synchronous grid (same frequency). Southern Regional grid is connected to this synchronous grid through HVDC links.A transmission plan has also been evolved for strengthening the regional grids and to support the generation capacity addition program of about 78,000 MW during XI Plan. In line with the perspective plan, various inter-regional transmission schemes have been undertaken for implementation by POWERGRID.Several milestones have been achieved by The Power Grid Corporation of India Ltd as a part of the development of the National Grid such as the implementation of Asia’s longest Talcher-Kolar HVDC Bipole link including its upgradation, Sasaram HVDC back-to-back link, 400 kV D/C Synchronous interconnection between Eastern and Western Region including series compensation, Augmentation of Gazuwaka HVDC, Muzaffarpur-Gorakhpur400 kV D/c line under Tala Transmission System, Agra-Gwalior 765 kV S/C line (operating at 400 kV), Patna-Balia 400 kV D/c line, Biharshariff-Balia 400 kV D/c line, etc. Establishment of the ultimate National Grid is on fast track and a number of projects are under implementation/ planned which would enhance Inter-regional power transfer capacity of the National Grid to more than 37,000 MW by year 2012.
