India–Sri Lanka HVDC Interconnection
The India – Sri Lanka HVDC Grid Interconnection is a proposed project to link the national grids of India and Sri Lanka. The project involves the construction of a high-voltage direct current (HDVC) connection between Madurai in southern India, and Anuradhapura in central Sri Lanka, through the Palk Strait. The link would measure 285 kilometres (177 mi) in length, including 50 kilometres (31 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.[1]

India's grid is connected to Bangladesh, Bhutan, and Nepal. This project will link Sri Lanka with the rest of the South Asian grid.[2]
Having been contemplated since 1970, the project has four implementation alternatives in consideration:[3]
- Madurai–Anuradhapura
- Thoothukudi–Puttalam
- Madurai–Puttalam
- Madurai–Anuradhapura (with back-to-back HVDC)
The connection will be developed in two phases, of which the first phase, scheduled to complete in the near-future, would enable the transmission of 500 MW between the two countries. The second phase would enable a 1,000 MW transmission capacity, the target capacity.[1]
It is expected to reach a total development cost of approximately US$800,000,000. Such a connection between the two countries would enable the nations to sell excess energy, thus saving valuable resources.[4]
In February 2016, Damitha Kumarasinghe, Director general of Public Utilities Commission of Sri Lanka, announced that pre-feasibility studies on the project had been completed.[5]
Additionally, the National Renewable Energy Laboratory in collaboration with Ceylon Electricity Board completed an operational analysis of the HVDC connection for one year of operations.[6]
But due to the ongoing 2019 economic crisis in Sri Lanka, the already planned 55 km under sea cable HVDC link is redesigned to be constructed as a over sea cable HVDC link, and the project is planned to be completed within 2030 from Madurai to Anuradhapura with the help of the World Bank.[7][8]
