Achieved through the commissioning of the 765kV Raichur-Solapur single circuit transmission line, the interconnection is not only expected to boost the inter-regional power transfer capacity of southern region, but also relieve the congestion experienced in few transmission corridors.
The commissioning comes five months ahead of its contractual schedule at a cost of approximately INR8.15bn ($131.9m).
The interconnection makes the Indian power system one of the largest operating synchronous grids in the world with about 232GW of installed power generation capacity.
The Indian power system currently operates through five regional grids, and a Pan India synchronous grid was considered for optimal utilization of the generation resources in the country.
The four regional grids, namely northern, eastern, western and north-eastern regions (NEW grid) were until now connected synchronously, while the southern region (SR) was connected to this NEW grid through high-voltage, direct current (HVDC) links.
