Hainan underwater grid ready to power FTZ development

An underwater grid project consisting of four 500-kilovolt alternating current submarine cables linking Hainan island and the mainland's other regions is set to undergo tests by the end of May as the island further diversifies its power transmission infrastructure.

The move comes close on the heels of policymakers charting plans to make the island's free trade zone more attractive to global investors.

Officials from EHV Power Transmission Co, the project's undertaker and a subsidiary of China Southern Power Grid, said CSG Main Grid and the Hainan Power Grid Interconnection Project II will connect Hainan's grid with the mainland's power grid in a two-way direction upon its completion.
