The policy outlines the Company’s approach and commitment to deal with environment and social issues, relating to transmission projects, and lays out management procedures and protocols to address the same. The policy and the initiatives taken by the Company for sustainable development of transmission system are applauded by the multilateral funding agencies like The World Bank & ADB and the same is applicable for all of its projects across the country. The Company has also been pro-active in bringing out the first ‘Sustainability Report’ in power sector, for measuring, disclosing and being accountable to internal and external stakeholders promoting excellence in for organizational performance and towards sustainable development.
Establishment of National Grid
POWERGRID has planned to create a strong and vibrant National Grid in the country in a phased manner to ensure optimum utilization of generating resources, conserve eco-sensitive right of way and accommodate uncertainty of generation plants. Strengthening of National Grid is planned in a phased manner through consolidation of inter-regional connection framework so as to support the anticipated generation capacity programme of about 50,000MW during the XII Plan.
At the end of XI Plan, the Inter-regional power transfer capacity of National Grid stands at about 28,000 MW. Four 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.
In 1994, the Government of India entrusted POWERGRID with further responsibility of controlling the existing load despatch centres in the country with a view to achieve better grid management and operation. For improving the efficiency, POWERGRID modernised all the Regional Load Dispatch Centres (RLDCs) with the state-of-the-art Unified Load Despatch & Communication (ULDC) schemes at a cost of about ` 2,000 Crore. These modernised RLDCs are greatly contributing to bring quality and economy in operation of power system besides improving data availability, visibility and transparency. Indian Power Grids have not experienced any major grid disturbance during the last eight years. For overall co-ordination, National Load Despatch Centre (NLDC) was established in 2009. As per the Govt of India directive, a separate company ‘Power System Operation Corporation Limited’ (POSOCO), a wholly owned subsidiary of POWERGRID, was formed in 2009 and is entrusted with the responsibility of Grid Operation and Management.
Development of Transmission System for Independent Power Producers
In order to meet the growing power demand of the country, Government of India has envisaged Capacity Addition through private sector participation and a number of Independent Power Producers (IPPs) have been setting-up/ plans to set-up power generation plants of different capacity with various time schedules in the country. These power generation plants are mainly coming up in resource rich states, i.e. Odisha, Jharkhand, Sikkim, Madhya Pradesh, Chhattisgarh, Tamil Nadu, Andhra Pradesh etc. and the power generated is required to be transmitted to load centres across the States and Regions.
Being the nodal agency for grant of Long Term Access (LTA) to private producers, the Company has undertaken development of high capacity transmission corridors for evacuation of large quantum of power from various IPP projects.
In order to evolve an economical transmission system to transfer such large quantum of power across long distances, 11 Nos. High Capacity Power Transmission Corridors have been planned and approved by CERC. These Transmission Corridors are coming up for IPPs situated in states of Jharkhand, Odisha, Chhattisgarh, Madhya Pradesh, Andhra Pradesh and Tamil Nadu. Implementation of these corridors has been taken up by the Company in a phased manner matching with progress of generation projects. This shall go a long way in integrated development of transmission system in the country.
Corporate Social Responsibility (CSR)
POWERGRID as a responsible corporate entity has taken up various programmes in different thrust areas like education, health, infrastructure development, games & sports etc for improving the standard and quality of life of local people, in and around its establishments as a Corporate Social Responsibility initiative. For taking up regular CSR activities, one percent (1%) of Profit after Tax (PAT) for the preceding year has been earmarked as non lapsable budget. The efforts made by POWERGRID have been applauded and earned the goodwill of the local inhabitants.
In order to address issues such as conserving Right-of-Way (RoW), minimizing impact on natural resources, coordinated development of cost effective transmission corridor, flexibility in upgradation of transfer capacity of lines matching with power transfer requirement and for development of economic inter-State transmission system, POWERGRID has undertaken several technological innovations. These include high temperature low sag Conductors, series compensation including Thyristor Control, Multi Circuits, GIS Mapping, Compact & Tall Towers, High Surge Impedance Loading Lines, hotline maintenance, live line washing of insulators; use of emergency restoration system, large scale automation of sub-stations, etc.
The 1200kV UHV AC technology is being developed by POWERGRID for the first time in the world. This is one of the unique R&D projects in public-private partnership model. During FY2011-12, POWERGRID test-charged one 1200kV Single circuit test line of 1km alongwith one 1200 kV transformer and other equipment.. The introduction of Ultra High Voltage in the transmission system will enhance power transfer capability of the line and reduce transmission losses and minimise Right of Way requirement.
Implementation of ±800 kV, 6000 MW HVDC Bi-pole of length around 2000km from North Eastern region (Biswanath Chariali in the State of Assam) to Northern Region (Agra in the State of Uttar Pradesh) is under construction. This shall facilitate high quantum of power transfer. Once implemented, this shall be the longest ±800kV HVDC line in the world.
