Azerbaijan, Georgia, Türkiye and Bulgaria on 10 November on the sidelines of the 31st UN Climate Change Conference (COP31) in Antalya, Türkiye. The agreement was signed by Azerbaijani Energy Minister Parviz Shahbazov, Georgian Deputy Prime Minister and Economy Minister Mariam Kvrivishvili, Turkish Energy and Natural Resources Minister Alparslan Bayraktar, and Bulgarian Energy Minister Iva Petrova. The initiative sets out an intergovernmental arrangement for advancing the Azerbaijan-Georgia-Türkiye-Bulgaria Green Energy Corridor, designed to enhance regional energy connectivity, expand electricity transmission routes and support the export of renewable electricity to European markets.

Under the agreement, the four countries will cooperate on the transmission, supply and trade of electricity generated from clean energy sources, the integration of their electricity networks, and the expansion of existing cross-border infrastructure through the construction of additional transmission lines. Their designated transmission system operators are expected to become shareholders in a joint venture responsible for developing and implementing the corridor projects. The agreement also envisages establishing and improving fibre-optic communications and data transmission infrastructure to support the energy network, alongside the technical, commercial and regulatory arrangements necessary to ensure reliable and uninterrupted electricity supplies. The planned transmission capacity of the corridor is estimated at 2,000-3,000 megawatts.

The project is intended to connect renewable electricity generation in the Caspian region with Türkiye and European markets through Georgia and Bulgaria. For Azerbaijan, it provides a framework for expanding renewable electricity exports and reinforcing its position as a regional energy hub. For Georgia, the initiative offers opportunities to increase cross-border transmission capacity, diversify electricity export destinations and facilitate access for domestically generated renewable energy to European markets. Turkish Energy Minister Alparslan Bayraktar described the initiative as the electricity equivalent of the Trans-Anatolian Natural Gas Pipeline (TANAP), highlighting its objective of delivering clean electricity along the Azerbaijan-Georgia-Türkiye-Bulgaria route to Europe.
