GECOGreen Energy Corridor Power Company
Caspian – Black Sea – Europe Green Energy Corridor

Renewable electricity from the Caspian to the heart of Europe

GECO develops a high-voltage direct current corridor that will carry wind and solar power from Azerbaijan through Georgia and under the Black Sea to Romania and Hungary.

The project

Three links, built as renewable generation grows

The Green Energy Corridor connects new wind and solar capacity in Azerbaijan with consumers in the European Union. Each link is a 525 kV voltage-source converter (VSC) HVDC system of 1,300 MW. Overhead lines cross Azerbaijan and Georgia; from the Georgian coast a submarine cable crosses the Black Sea, mostly over the abyssal plain at depths of about 2,200 metres, to Constanța in Romania.

Converter stations in Georgia connect the corridor to the Georgian grid, so Georgia can export its own renewable surplus and import when it needs to. In Romania and Hungary the inland route follows existing infrastructure corridors to Bucharest and to Albertirsa near Budapest.

A Feasibility Study by CESI, covering resources, demand, technology, routing, grid integration and the business model, was completed and approved by the four governments in July 2026. The project has now entered its development phase.

Commissioning years are the planning dates in ENTSO-E's Ten-Year Network Development Plan 2026, where the corridor appears as projects 1248 (Phase 1, Links 1 and 2) and 1244 (Phase 2, Link 3). The schedule will be confirmed in the roadmap to the final investment decision.

For Europe

New, diverse supply

A new route for clean electricity into the Union, lowering wholesale prices in Romania and Hungary and displacing gas-fired generation.

For the region

Market integration

A direct electricity link between the South Caucasus and the EU market, connecting the transmission systems of four countries.

For the climate

Renewables at scale

Opens strong Caspian wind and solar resources to export, supporting the decarbonisation goals of all four countries.

The company

A joint venture of four national power companies

Green Energy Corridor Power Company (GECO) is the joint venture set up in Bucharest by the governments' designated companies to develop the corridor. It leads the project from feasibility to the final investment decision and financial close, working with the transmission system operators of the four countries.

GECO acts under the Agreement on Strategic Partnership in the field of Green Energy Development and Transmission, signed by the Governments of Azerbaijan, Georgia, Romania and Hungary in Bucharest on 17 December 2022. The Ministerial Meeting of the Parties sets its mandate and approves its plans.
