The 328 kilometre underwater cable with a 1,000 megawatt capacity will be linked to another cable that Cyprus, Greece and Israel plan to build to interconnect their power grids - the so-call Euro-Asia Interconnector that will cross the Mediterranean seabed.

The EIB has agreed to extend a 200 million euro loan to IPTO with an option of an additional financing of 100 million euros under a 20-year facility, IPTO said in a statement.

IPTO already has a 200 million euro loan from Eurobank, and will also use its own and European funds for the project, which is expected to be built by 2023, it said.
