Great Sea Interconnector

Question for written answer E-001669/2026
to the Commission
Rule 144
Yannis Maniatis (S&D)

The Great Sea Interconnector, recently included for the 7th time in the EU list of Projects of Common Interest (PCI), having received significant funding from the Connecting Europe Facility (CEF) and being one of the Energy Highways of the December 2025 European Grids Package, 'meets the criteria of the TEN-E Regulation, including a positive cost-benefit analysis', as the Commission acknowledges in its previous response (E-004589/2025/18.2.2026[1]). However, in the autumn of 2025, the Greek and Cypriot authorities chose to delay the project, stating that they would commission a study to examine some of its economic parameters, which - according to reports - despite several months passing, has not yet been commissioned.

Given the deteriorating situation of the energy market due to successive war/energy crises, the Interconnector's geopolitical and energy importance (ending Cyprus's isolation, market integration, the promotion of green electricity, etc.), the Commission's long-standing practical support for the project, but also its stated intention to accelerate the energy union in the EU:

• 1.Does the Commission know when commissioning of the study will take place and on what timetable?
• 2.Have the Greek and Cypriot authorities requested financial or technical assistance for the study from European institutions (Commission, EIB, etc.)?
• 3.Among its new initiatives to respond the energy crisis, is the Commission planning measures for interconnections that are facing serious implementation delays, such as this one?
