ADB Commits $2.5 Billion to Azerbaijan as Caspian Green Energy Corridor Feasibility Study Advances

The Asian Development Bank has committed up to $2.5 billion in investment to Azerbaijan under a new country partnership strategy, affirming the multilateral lender's confidence in Baku's role as a regional energy hub and financing anchor for a pipeline of renewable energy and infrastructure projects across the South Caucasus and Caspian basin.

ADB mission chief Sunniya Durrani-Jamal stated that Azerbaijan has confidently secured its status as a strategic energy bridge between regions, and that the Caspian Green Energy Corridor — developed jointly with Kazakhstan and Uzbekistan — represents a natural progression of this role. The feasibility study for the corridor was officially launched in February 2026, with its development based on a Memorandum of Understanding signed in April 2025. During a seminar in Baku, participants finalized approaches, defined a timeframe, and outlined preparations for the second phase of the study, which aims to assess technical, economic, and regulatory requirements for transmitting large-scale Central Asian renewable power through Azerbaijan and the South Caucasus to European markets.

ADB's existing renewable energy portfolio in Azerbaijan already spans nearly 1 gigawatt of commissioned and under-development solar capacity, including the landmark 230-megawatt Garadagh Solar Plant — the first utility-scale solar facility in the country — and the 445-megawatt Bilasuvar and 315-megawatt Banka/Neftchala solar projects. ADB is also supporting Azerbaijan's district heating decarbonization through technical assistance on policy reform and operational modernization. According to Report.az, the bank sees Azerbaijan's existing energy infrastructure and cross-border experience as a critical enabler for the corridor's eventual implementation.

The corridor initiative requires not only physical infrastructure but also compatible regulatory frameworks, coordinated transmission planning, and commercial clarity across Kazakhstan, Uzbekistan, and Azerbaijan. ADB has emphasized that its contribution is focused on ensuring the feasibility work is backed by a comprehensive technical assessment and structured regional dialogue — moving the project from strategic intent to practical implementation rather than leaving it as a policy aspiration.

For institutional investors, ADB's $2.5 billion commitment and the active feasibility work signal that the Caspian corridor is a serious infrastructure initiative with credible international financial backing. Eurasianet has covered how Central Asian renewable exporters — particularly Kazakhstan — stand to benefit from a functioning corridor that reduces dependence on Russian-dominated energy transit routes.
