	The '''India – Sri Lanka HVDC Grid Interconnection''' is a proposed project to link the [[power grid\|national grids]] of [[India]] and [[Sri Lanka]]. The project involves the construction of a [[~~High~~-voltage direct current~~\|HVDC~~]] connection between [[Madurai]] in southern India, and [[Anuradhapura]] in central Sri Lanka, through the [[Palk Strait]]. The link would measure {{convert\|285\|km\|mi}} in length, including {{convert\|50\|km\|mi}} of submarine cables, and would take more than three years to construct. It would be implemented by the [[Power Grid Corporation of India Limited]] and [[Ceylon Electricity Board]].<ref name="rtt">		The '''India – Sri Lanka HVDC Grid Interconnection''' is a proposed project to link the [[power grid\|national grids]] of [[India]] and [[Sri Lanka]].
