16 Chapter - 7 Transmission Transmission projects continue to be accorded a high priority in the context of the need to evacuate power from the generating stations to the load centres, system strengthening and creation of National Grid. POWERGRID’s transmission projects construction targets for the year 2003-04 and achievement are summarised below: Works Programme for the year Achievement upto % of 2003-2004 (Ckt. Kms.) March, 2004 Achievement 800/400/220 kV 1580 2487 157 EHV AC & 500 kV HVDC lines CENTRAL SECTOR TRANSMISSION POWERGRID, the ‘Central Transmission Utility’, is the sole agency responsible to establish the requisite transmission capacity in the central sector to match the generation capacity addition and encourage inter-state/inter-regional exchange of power to mitigate the situation of surplus/deficit of energy in various regions. POWERGRID’s transmission lines and sub-stations completed during the year 2003-04 are shown in the following table: S. No. Name of the line/Sub-station Voltage Class 1. Salem-Udumalpet S/C 400 kV 2.

ICT – III at Biharshariff 400/ 200 kV TOWARDS FORMATION OF NATIONAL GRID POWERGRID has envisaged establishment of an integrated National Power Grid in the country by the year 2012 with an inter-regional power transfer capacity of 30,000 MW. A perspective transmission plan has been evolved for strengthening the regional grids with ultimate objective of establishment of strong & vibrant National Power Grid in a phased manner to support the generation capacity addition program of about 1,00,000 MW during X & XI Plans. The major considerations followed while formulating such a perspective plan are, creation of “Transmission Highways” from potential generating resources mainly
in Eastern & North-Eastern Regions to major load centers in Northern, Southern & Western Regions for their optimum utilization, conservation of precious Right-of-Way along eco-sensitive areas and to achieve economy (cost/MW) in long-term. Phase - I Number of schemes have already been implemented by POWERGRID towards development of the first phase of the National Power Grid. In addition to few AC inter-regional links, there are four HVDC back-to-back interregional links already under operation, which include 500 MW HVDC back-to-back link interconnecting Western and Northern Region at Vindhyachal, 1000 MW HVDC back-to-back link interconnecting Western and Southern Region at Chandrapur, 500 MW back-to-back link interconnecting Eastern and Southern Regions at Gazuwaka, 500 MW Sasaram HVDC back to back link interconnecting Eastern Region with Northern Region at Sasaram. Under the first phase, all the power regions of the country have been interlinked mainly through a synchronous HVDC links and an inter-regional power transfer capacity of 5,000 MW has been achieved. Phase - II Implementation of second phase of the National Grid has already begun with the commissioning of 2000 MW Talcher-Kolar bi-polar HVDC link, 9 months ahead of schedule and at a cost lower by Rs. 700 Crore than the approved cost. The 400 kV D/C Raipur-Rourkela line (East- West Interconnector) was commissioned in March’2003, one year ahead of schedule, thereby achieving the cumulative inter-regional power transfer capacity of 8000 MW. With this the synchronous operation of regional grids covering North-Eastern, Eastern, and Western Regions with a combined installed capacity of over 50,000 MW stretching from Arunachal Pradesh in North Eastern Region to Goa in Western Region, i.e. a distance of more than 2500 Km, covering an area of 16 lac sq. Km, has been achieved. POWERGRID has been giving special emphasis for enhancing the inter-regional power transfer capacity to facilitate optimal utilization of available energy resources. As a result of concerted efforts, inter-regional transmission of energy increased from mere 3600 MUs in 1997 to over 22,000 MUs during the year 2003-04. Similarly, during the same period the inter-regional power transfer capacity has been enhanced from 1200 MW to 8000 MW. Doubling of capacity of Gajuwaka HVDC backto-back link by establishing additional 500 MW block is already under implementation for enhancing the power transfer capacity between Eastern Region & Southern Region. This project is expected to be completed by Mar’2005. The second phase of National Grid consisting of a hybrid system of HVDC & 765 kV systems is expected to be achieved by the year 2007, when the inter-regional power transfer capacity is envisaged to be about 23,500 MW, depending upon commissioning of planned generation projects. Phase - III In the ultimate phase, a strong National Grid has been envisaged to evacuate the power from major generating resources including hydro projects in North-Eastern Region and large sized Thermal Power Plants in Jharkhand/Bihar, Orissa and Madhya Pradesh. The scheme for National Grid involves development of high capacity transmission corridor in chicken-neck area (falling between Nepal & Bangladesh) and establishment of a ring of 765 kV lines interconnecting all the electrical regions. Cumulative inter-regional transmission capacity of the National Grid would increase to about 30,000 MW by the end of XI plan depending upon pace of generation capacity addition. FORMATION OF SAARC GRID As per an estimate, the hydro potential of Bhutan is 21,000 MW, that of Nepal is 83,000 MW, and of Pakistan is 36,000 MW. Bangladesh has gas potential to the tune of 40,000 bcf. India being centrally placed in South Asian region, sharing political boundaries with four SAARC countries can play a major role in facilitating interconnection between these countries leading to formation of SAARC Grid for effective utilization of Regional Resources. PRIVATE SECTOR PARTICIPATION IN TRANSMISSION For creation of National Grid including the evacuation system for associated generation projects, the total investment requirement in the central transmission sector during next 10 years has been envisaged to be about Rs. 70,000 Crore. Out of this, POWERGRID plans to invest to the tune of Rs. 50,000 Crore, while the balance of Rs. 20,000 Crore is envisaged to be mobilized through Private Participation.
