One Nation, One Grid

  • In a move to improve India’s connectivity infrastructure, the government in its second term plans to build a model of ‘One Nation, One Grid’ to ensure availability of power to states at ‘affordable’ rates.
  • FM in his budget speech made available a blueprint for developing gas grids, water grids, i-ways, and regional airports.
  • The government is also examining the performance of its Ujjwal DISCOM Assurance Yojana (UDAY), aimed at financial and operational turnaround of power distribution companies.

Power grids in India

  • The Indian Power system for planning and operational purposes is divided into five regional grids.
  • The integration of regional grids, and thereby establishment of National Grid, was conceptualized in early nineties.
  • The initial inter-regional links were planned for exchange of operational surpluses amongst the regions.
  • However, later on when the planning philosophy had graduated from Regional self-sufficiency to National basis, the Inter-regional links were planned associated with the generation projects that had beneficiaries across the regional boundaries.

Evolution of National Grid

  • Grid management on regional basis started in sixties.
  • Initially, State grids were inter-connected to form regional grid and India was demarcated into 5 regions namely Northern, Eastern, Western, North Eastern and Southern region.
  • In October 1991 North Eastern and Eastern grids were connected.
  • In March 2003 WR and ER-NER were interconnected .
  • August 2006 North and East grids were interconnected thereby 4 regional grids Northern, Eastern, Western and North Eastern grids are synchronously connected forming central grid operating at one frequency.
  • On 31st December 2013, Southern Region was connected to Central Grid in Synchronous mode with the commissioning of 765kV Raichur-Solapur Transmission line thereby achieving ‘ONE NATION’-‘ONE GRID’-‘ONE FREQUENCY’.

About National Grid

  • The National Grid is the high-voltage electricity network in mainland India, connecting power stations and major substations and ensuring that electricity generated anywhere in mainland India can be used to satisfy demand elsewhere.
  • The National Grid is owned, operated, and maintained by state-owned Power Grid Corporation of India.
  • It is one of the largest operational synchronous grids in the world with 334.40 GW of installed power generation capacity as on 31 January 2018.

 Benefits of centralized power grid

  • Synchronization of all regional grids will help in optimal utilization of scarce natural resources by transfer of Power from Resource centric regions to Load centric regions.
  • Further, this shall pave way for establishment of vibrant Electricity market facilitating trading of power across regions.
  • One Nation One Grid shall synchronously connect all the regional grids and there will be one national frequency.
