Sri Lanka and India are considering constructing an undersea power cable between the two countries. Both the countries have been working on the undersea route since 2013. Originally, the proposed India–Sri Lanka interconnection project involved the construction of a high voltage direct current (HVDC) link spanning 283 km to connect Madurai in India and Trincomalee in Sri Lanka. Of the total length, 39 km was proposed as an undersea cable in the Gulf of Mannar. Currently, the initially proposed route has been realigned and made shorter by around 50 km. India’s Power Grid Corporation of India Limited is likely to be involved in the construction of the sea link. The link is expected to help Sri Lanka meet its electricity demand.
