Now, uninterrupted power transmission throughout the nation

Power Grid CMD RN Nayak
GIVING a further boost to the power scenario of the nation, southern grid synchronously connected with the National Power Grid, making Indian power system one of the largest operating synchronous grids in the world. This will ensure faster and uninterrupted power transmission across country, the government said on Wednesday. The southern grid connectivity was achieved on Tuesday evening (December 31, 2013) through commissioning of...
Raichur-Solapur 765 kV single circuit transmission line by Power Grid Corporation of India Limited facilitating bulk transfer of power across regional boundaries, said a press statement. This line of 208 circuit km (ckm) and 765/400 kV substations at Raichur and Sholapur has been commissioned five months ahead of its contractual schedule (May 31, 2014) at a cost of Rs 815 crore, the release added. With this, the mission of ‘One Nation – One Grid – One Frequency’ has been successfully accomplished, the release added.
With this interconnection, Indian power system has entered into a new era and become one of the largest operating synchronous grids in the world with about 232GW of installed power generation capacity. Synchronous integration of Southern Grid with rest of the national power grid is likely to augment the inter-regional power transfer capacity of southern region. This will also relieve the congestion being experienced in few transmission corridors.
By the end of 11th plan the country has total inter-regional transmission capacity of about 28,000 MW which is expected to be enhanced to about 65000 MW at the end of XII plan.
Indian power system is operating through five regional grids and a pan India synchronous grid was envisaged for optimal utilization of the generation resources. Till now, four regional grids namely Northern, Eastern, Western and North-eastern regions (NEW grid) were connected synchronously and Southern Region (SR) was connected to this NEW grid through HVDC links. Synchronous interconnection of SR with NEW grid was envisaged through high capacity 765 kV Raichur – Sholapur lines, as an ultimate step towards establishment of an “All India Synchronous National Grid” facilitating bulk transfer of power across regional boundaries.
The Navaratna company is the Central Transmission Utility (CTU) of the nation under ministry of power and is playing a vital role in the growth of Indian power sector by developing a robust Integrated National Grid and associating in the flagship programme of govt of India to provide power for all.
