Meridiam Takes Majority Stake In Great Sea Interconnector

French infrastructure investment group Meridiam has officially become the majority shareholder of the Great Sea Interconnector (GSI), marking a significant step forward for the electricity link between Cyprus and Greece.

The agreement was signed on Wednesday at Greece’s Maximos Mansion in the presence of Prime Minister Kyriakos Mitsotakis, who described the project as strategically important for regional energy security and for ending Cyprus’ energy isolation from the European electricity grid.

Mitsotakis also said the deal demonstrates Greece’s ability to attract international investors and pledged continued government support to ensure the project moves forward.

Project Gains New Momentum

Alongside the shareholder agreement, Greece’s Independent Power Transmission Operator (IPTO), GSI and French cable manufacturer Nexans signed a separate agreement covering seabed survey work, one of the next stages in the project’s development.

Greek officials said Meridiam’s entry strengthens the project’s financial position and credibility, creating better conditions to accelerate construction. IPTO will remain a strategic shareholder, retain technical responsibility for the project and operate the interconnector once it is completed.

The European Investment Bank is also assessing potential financing, while IPTO is preparing to submit a cost-benefit study for the planned Cyprus-Israel electricity interconnection to regulators in Cyprus and Israel.

Long-Term Infrastructure Investor

Founded in 2005 and headquartered in Paris, Meridiam specialises in financing, developing and managing long-term infrastructure projects. Its portfolio includes more than 130 projects across Europe, North America, the Middle East and Africa, spanning sectors such as transport, energy and water infrastructure.

Among its flagship investments are the NeuConnect electricity interconnector between the UK and Germany, Sofia Airport in Bulgaria and the Florence tram network in Italy.

Limassol Port Electrification Awaits Grid Connection And EU Funding

Plans to equip Limassol port with shore-side electricity are advancing at the technical level, but unresolved administrative procedures, a pending grid connection and the need to secure European funding continue to delay implementation.

The proposed shore-power system, also known as cold ironing, would allow vessels to connect to electricity while berthed, reducing reliance on onboard engines and cutting emissions and noise in the surrounding area.

Technical Studies Near Completion

Transport Minister Evi Tsolaki said work is progressing through the EU-backed DecarbonLim programme, which is preparing the technical assessment and feasibility study required before construction can begin. The ministry is seeking regular updates from the Cyprus Ports Authority on the studies’ completion timetable.

The initiative also involves Frederick University, Eurogate Container Terminal Limassol, DP World Limassol, the Electricity Authority of Cyprus, the Cyprus Transmission System Operator and Limassol Municipality.

Grid Connection Remains A Key Hurdle

Despite progress on the studies, construction cannot proceed until the project secures a connection to the national transmission network.

Tsolaki said the ministry has requested land from the Department of Lands and Surveys for an electricity substation. Once the site is allocated, the relevant applications can be submitted to the Cyprus Transmission System Operator to advance the grid-connection process.

Until these steps are completed, the project will remain in the preparatory phase, even if the technical studies are finalised.

European Funding Adds Urgency

The feasibility work under DecarbonLim will support an application for construction financing, Tsolaki said. A competitive European funding call is currently open, and the ministry intends to submit an application within the required timeframe.

The funding window has raised concerns in parliament. MP Fotini Tsiridou warned that further delays could undermine Cyprus’ chances of securing EU support, noting that similar port electrification projects elsewhere in the bloc have already received funding.

Speaking to Entrepreneurial Limassol, published by the Limassol Chamber of Commerce and Industry, Tsiridou said she had observed some progress but had yet to receive a formal response to her parliamentary question.

Environmental And Commercial Benefits

Tsiridou argued that shore-side electricity would deliver benefits beyond emissions reductions, including less noise and air pollution for residents near the port.

“Our port should not be disconnected from the rest of the city,” she said, describing shore-power infrastructure as both a necessity and a European obligation.

Across Europe, port electrification is increasingly linked to environmental performance and competitiveness. By allowing compatible vessels to switch off auxiliary engines while docked, shore-power systems can reduce local emissions and noise while supporting wider decarbonisation goals.

Construction Timetable Still Unclear

The Cyprus Ports Authority signed a contract with DBA S.p.A. in July 2025 for a comprehensive study of the system’s technical, economic and environmental requirements. The work was intended to establish the basis for installation and identify any necessary port infrastructure upgrades.

More than a year later, key steps concerning land allocation, grid connection and financing remain unresolved. No timetable has been announced for completing these procedures or submitting the final funding application.

Limassol’s shore-power project therefore remains between planning and implementation. Its next milestones are securing the substation site, progressing the transmission-network application and obtaining construction financing. Until these are in place, the port’s transition to shore-side electricity cannot move into the construction phase.
