The Great Sea Interconnector (GSI) has taken another step forward after Greece’s Independent Power Transmission Operator (Admie) submitted an investment request for the Cyprus-Israel electricity link to the energy regulators of both countries.

Marking the next stage of the project under the European Union’s Trans-European Networks for Energy (TEN-E) framework, the application comes amid renewed efforts to advance the strategic connection between Greece, Cyprus and Israel. French infrastructure investment group Meridiam recently became the majority shareholder in the GSI project company, while Greek and Israeli officials have also stepped up discussions on the Cyprus-Israel section.

Investment Framework Moves To Regulatory Review

Admie said the request follows completion of the required cost-benefit analysis (CBA) and cross-border cost allocation proposal (CBCA). Authorities and grid operators in Cyprus and Israel were consulted during the studies, which also incorporated updated forecasts for electricity demand, renewable energy development and future grid requirements.

According to the findings, the Cyprus-Israel interconnection remains economically viable under all scenarios examined. The project is also expected to strengthen electricity supply security, support renewable energy integration and connect the eastern Mediterranean electricity market more closely with the wider European grid.

Regulators in Cyprus and Israel will now formally assess the investment request and jointly determine how the project’s costs will be allocated between the two countries and recovered through regulated revenues.

Following approval of the investment framework, the project can move towards a final investment decision, allowing financing arrangements to proceed. Admie also plans to attract additional investors to the Cyprus-Israel section, following the model used for the Greece-Cyprus leg.

1,000MW Link To Connect Cyprus And Israel

Designated by the EU as a Project of Common Interest, GSI will have a transmission capacity of 1,000MW using a 500kV high-voltage direct current system. A planned submarine cable between Cyprus and Israel will stretch approximately 324 kilometres at depths of up to 2,400 metres, allowing electricity to flow in both directions.

Last week, Energy Minister Michael Damianos welcomed Meridiam’s entry into the project and said Cyprus would await the European Investment Bank’s due diligence assessment before considering whether the Republic should become a shareholder.

Separately, a bipartisan group of US lawmakers has urged Secretary of State Marco Rubio and US International Development Finance Corporation chief executive Ben Black to prioritise GSI, citing its importance for regional energy security and cooperation.
