India is now amongst the fastest developing countries in the world in terms of GDP as well as the electricity consumption. The challenge is to meet the energy needs of high economic growth & electricity consumption of about 1.3 billion people. The development of an efficient, coordinated, economical and robust electricity system is essential for smooth flow of electricity from generating station to load centers (as per Electricity Act, 2003) and for optimum utilization of resources in the country, in order to provide reliable, affordable, un-interruptible (24x7) and Quality Power for All. Transmission system establishes the link between source of generation on one side and distribution system, which is connected to load / ultimate consumer, on the other side. Transmission planning is a continuous process of identification of transmission system addition requirements, their timing and need. The transmission requirements could arise from:
- new generation additions in the system,
- increase in demand
- system strengthening that may become necessary to achieve reliability as per the planning criteria under change load-generation scenario.
As per Section 3 of the Electricity Act 2003, Central Electricity Authority (CEA) has been entrusted with the responsibility of preparing the National Electricity Plan (NEP) in accordance with the National Electricity Policy and to notify such plan once in five years. The National Electricity Plan (Volume I) on Generation Planning has been prepared by CEA. National Electricity Plan Volume II (Transmission) is being prepared, incorporating the review of development of transmission system during 2017-22 , Planning for the ongoing plan period 2022-27 and Perspective plan for 2027-32 keeping in view various factors, such as inter-regional transmission links, reactive compensation, cross border exchange of power etc. The system studies for NEP Vol II (Transmission) 2022-27 have been performed considering draft National Electricity Plan (Vol 1: Generation) and taking relevant inputs from all the stake holders (STUs/Electricity Departments, CTUIL, POSOCO etc). The draft NEP Vol II (Transmission) 2022-27 is under finalization.
