On 19 January 2026, Bulgaria, Greece and Romania signed a trilateral Declaration of Intent in Athens to advance a new package of cross-border renewable energy initiatives, aiming to strengthen regional energy security and accelerate decarbonisation in Southeast Europe.
The three countries agreed to cooperate on projects in offshore wind, renewable hydrogen and electric vehicle charging infrastructure. A key part of the plan is a joint effort to explore offshore wind potential in both the Black Sea and the Aegean Sea, including preparatory studies and work toward a more harmonised regulatory framework. The partners also plan to apply for cross-border renewable energy status under the current Connecting Europe Facility (CEF) call.
The declaration also outlines the creation of a regional renewable hydrogen cluster involving governments, transmission system operators and industry. The initiative is expected to support wind and solar deployment, integrate clean energy into a low-emissions system, and develop hydrogen production and infrastructure for energy, industrial and transport needs.
In addition, the three countries highlighted the importance of expanding cross-border EV charging networks, while leaving the door open for further cooperation in other energy-related areas by mutual agreement. The overall goal is to develop projects of shared regional interest and support a fair transition toward a climate-neutral economy.
