Romania Joins Azerbaijan-Georgia Green Energy Corridor as Black Sea Cable Project Advances

The Caspian-Black Sea-Europe green energy corridor took a significant step forward in early 2026 as Romania formally expressed its intention to join the Azerbaijan-Georgia-Türkiye-Hungary framework, according to reports that Türkiye is preparing a draft protocol to amend the founding April 2025 Memorandum of Understanding. The expansion signals growing European appetite for Azerbaijani renewable electricity as the continent continues its post-Russian energy reorientation.

At the technical level, the project envisions a 1,155-kilometre undersea power transmission cable laid across the Black Sea, connecting Azerbaijan and Georgia to Romania with a capacity to transmit up to 1,300 megawatts of renewable electricity. The cable received EU Project of Mutual Interest status in December 2025, unlocking access to preferential financing and streamlined regulatory processes across member states. In October 2025, the project was officially added to the TYNDP 2026 — the European Network of Transmission System Operators' Ten-Year Network Development Plan — cementing its place in European grid planning frameworks.

A joint venture established by transmission system operators from Azerbaijan, Georgia, Romania, and Hungary has been formally constituted to manage project development. The feasibility study is expected to conclude in the coming months, with the first phase of the cable targeted for completion in 2032, followed by additional phases in 2036 and 2040. Once fully operational, the corridor would provide Europe with a direct, non-Russian renewable electricity supply route stretching from the Caspian basin to the Black Sea.

Azerbaijan's green energy production capacity makes the project commercially viable. The country is developing 27 gigawatts of wind and solar generation capacity, with projects expected to add a further 4 GW by the end of 2027. Crucially, 80% of new green output is earmarked for export — meaning that European demand for Azerbaijani renewables aligns directly with the country's domestic industrial strategy. According to CEE Energy News, the corridor is widely seen as one of the most commercially credible renewable energy export projects in the former Soviet space.

Georgia occupies a pivotal position in the corridor. Tbilisi serves as both a transit state and a grid interconnection point between Azerbaijani generation assets and the Black Sea crossing. Georgian transmission infrastructure investments are expected to receive co-financing from European institutions, reflecting the country's growing integration into the EU energy single market framework, a process accelerated by Georgia's EU candidate status.

The World Economic Forum noted in January 2026 that traditional energy producers like Azerbaijan must be central participants in the green transition rather than peripheral actors, pointing to the country's dual capacity as a hydrocarbons exporter and an emerging renewables supplier. This argument is now being translated into hard project commitments and multilateral financing structures.

As referenced by BlackSea Caspia, the corridor's TYNDP 2026 inclusion marks a transition from aspiration to engineering reality, with pilot project parameters now defined within European grid planning frameworks for the first time.
