A bipartisan group of US lawmakers has urged Secretary of State Marco Rubio and US International Development Finance Corporation (DFC) Chief Executive Officer Ben Black to prioritise the Great Sea Interconnector (GSI), describing it as a strategic infrastructure project that would strengthen cooperation and energy security in the Eastern Mediterranean.
According to a joint press release issued on Tuesday, Congressmen Brad Schneider and Gus Bilirakis led the initiative, sending a letter to Rubio and Black calling on the US Administration to support the electricity interconnection project linking the power grids of Greece, Cyprus and Israel.
In their letter, the lawmakers said the Great Sea Interconnector would play a key role in the development of the India-Middle East-Europe Economic Corridor (IMEC), describing the Eastern Mediterranean as a vital gateway for the initiative.
“The Eastern Mediterranean will play a vitally important role as a gateway to IMEC, and the Great Sea Interconnector is a key strategic infrastructure project central to the development of the corridor”, they wrote.
The lawmakers argued that the project would strengthen US partners in the region, diversify energy routes, deepen regional integration and provide a transparent alternative to infrastructure dominated by strategic competitors.
They noted that by linking the electricity grids of Greece, Cyprus and Israel, the interconnector would end Cyprus’ isolation from the European electricity transmission system, enhance Israel’s energy security and facilitate reliable two-way electricity flows between Europe and the Eastern Mediterranean.
The members of Congress also said the project advances the objectives of the bipartisan Eastern Mediterranean Gateway Act, introduced by Schneider and Bilirakis in May 2025. The legislation aims to strengthen the Eastern Mediterranean’s role as a strategic link between India, the Middle East and Europe and calls for enhanced US support for regional infrastructure, energy interconnectors and strategic cooperation with Greece, Cyprus, Israel, Egypt and other regional partners.
In their letter, the lawmakers urged the State Department and the DFC to give priority to the Great Sea Interconnector and requested a classified briefing on the geopolitical challenges affecting the project’s completion.
The letter was also signed by Representatives Jake Auchincloss, Dan Goldman, Craig Goldman and Haley Stevens.
