India, Sri Lanka plan underwater power line

India’s first undersea power transmission project with Sri Lanka is likely to be implemented by 2014. The Power Grid Corporation, India’s largest electricity transmission firm, which will execute the project, will give the detailed project report (DPR) to the Indian Government within a month.

“It is upon the Ministry then to fast track the plan,” quoting a top Power Grid official, Business Standard reported.

The 250-300 km power link, including submarine cables over a stretch of over 50 km, will be jointly implemented by Power Grid and Ceylon Electricity Board (CEB). The project is expects to start by 2014.

CEB, too, seemed optimistic about the date of the project. “If everything goes well, the project will take off. But I am not sure about the timing, since we have to wait for a feasibility report. On the basis of the report, we will fine-tune the plan,” said Vidya Amarapala, CEB Chairman.

“The estimated cost of this venture will be Rs. 3,000-4,000 crore and is likely to transmit about 1,000 Mw by the end of the 12th Five Year Plan period,” the Power Grid official said. The possible spot for this linkage is between Rameswaram in Tamil Nadu and Talaimannar in Sri Lanka. “The final decision on exact route will be taken by the two Governments,” he added.

CEB has an installed capacity of 2,684 Mw, of which approximately 1,290 Mw is of thermal energy, and 1,207 Mw of hydroelectricity. India’s largest power producer, NTPC, too, has plans to foray into Sri Lanka by setting up a 500-Mw plant in association with CEB. This project, too, is in the final stages of clearance by the Indian Government.

“It will be a direct link. There are similar grid connectivities in other parts of the world like the United Kingdom to Europe, the United States to Canada and East Europe to European grid. The technology for submarine transmission will be the same as these countries are using now,” Amarapala said.

“Power Grid already has some overseas projects going on. While the Bhutan project is operational, a linkage with Bangladesh is under construction. But the Sri Lanka venture is important as it is an underwater linkage,” the Power Grid official said.

“For the power industry, this will not have any impact other than just a bilateral confidence-building measure. The technology should be of global standard as an underwater line needs higher expertise compared to in-land power linkage and it will be a challenge for both the countries. If works out, it may help us in transmitting the power produced by the NTPC plant in Sri Lanka,” said Rupesh Sankhe, a Research Analyst with Angel Broking.

“CEB expects this bilateral project to be beneficial for both countries. We want it to be balanced marriage,” quoting Amarapala, Business Standard reported.
