Shaken by the recent failure of the northern grid and subsequent collapse of the eastern and north-eastern grids, the Power Ministry has decided to take up the work of connecting the southern grid with the national grid on a war footing, a task that is likely to be achieved by 2014.
Ministry officials said that after having learnt a lesson from the two-day blackout in major parts of the country, the Ministry has stepped up the work of integrating the southern grid with the national grid that could not only help in efficient and effective transfer of electricity from various regions, but also provide a huge relief to the power starved South.
Officials said directions were issued by the Ministry to the Power Grid Corporation of India Limited to put the work on two 765 kV transmission lines linking Sholapur and Kolhapur in Maharashtra to Raichur and Narendra in Karnataka on the fast track and complete it by 2014.
The two links, expected to cost around Rs. 2,500 crore, will provide the link to the southern grid.
The officials said the linkage would help in stabilising the transmission system and also help in transmitting power to the southern States during crises.
“There are situations around the year when the northern grid is generating surplus power. At present, this surplus cannot be utilised by the southern grid as there is no credible linkage. But by 2014, all this will be history and South India will get a big relief in the shape of the facility to transfer power from one region to another,” a senior official said.
The country has northern, eastern, north-eastern, southern and western grids. All of them, except the southern grid, are interconnected synchronously.
At present the inter-regional transmission capacity between West and South is 1,500 MW. With the construction of transmission lines between Maharashtra and Karnataka, the capacity will go up to 5,000 MW.
