How Kazakhstan, Azerbaijan and Uzbekistan Plan to Link Central Asian Green Power to Europe
ASTANA – Kazakhstan, Azerbaijan and Uzbekistan are advancing plans for the Caspian Green Energy Corridor that would allow renewable electricity generated in Central Asia to reach European markets. The Astana Times takes a closer look at the project’s scale, economics and strategic significance
The project stems from the agreement,signedby the leaders of Kazakhstan, Azerbaijan and Uzbekistan in Baku in November 2024, that establishes a framework for closer cooperation on renewable energy development, energy efficiency and the export of renewable energy to international markets

Centered on a planned high-voltage submarine cable across the Caspian Sea, the initiative aims to connect Central Asia’s rapidly growing renewable energy sector with European markets through Azerbaijan and a broader Black Sea electricity network.
“The initiative aims to establish a Green Energy Corridor that would enable the export of renewable electricity, hydrogen and green ammonia from Central Asia to Europe Times in a comment for this story.
“A key component of the project is the planned construction of a high-voltage direct-current submarine cable across the Caspian Sea. This strategic decision would provide Kazakhstan with direct access to the European Union’s electricity markets through a similar project planned in the Black Sea,” it added.

The necessaryinfrastructure will be built in the Mangystau Region in western Kazakhstan, according to the ministry
The Asian Development Bank (ADB), the Asian Infrastructure Investment Bank (AIIB) and the energy ministries of Azerbaijan, Kazakhstan and Uzbekistansigneda memorandum of understanding in April 2025 to support a feasibility study for the project
Italian consulting and engineering company CESI has begun work on the study.Phase 1 was launched in January, and according to the Kazakh ministry, the study is estimated to cost one million euros ($1.2 million).
“The study will assess the technical, economic, regulatory, and environmental for the development of one of the most ambitious green energy corridors connecting Central Asia and Europe,” saidCESI.
According to the company, the corridor aims to integrate up to five gigawatts of capacity by 2030

To oversee implementation, the three countries established the Green Corridor Alliance joint venture. It was officially registered in Baku in July 2025, with the founding shareholders being Azerenerji, National Electric Grids of Uzbekistan, and Kazakhstan Electricity Grid Operating Company (KEGOC).
According to KEGOC, the study is expected to be completed in May 2027.
“The project is expected not only to expand export opportunities, but also position Kazakhstan as a key player capable of implementing large-scale technological initiatives in sustainable energy,” said the Kazakh ministry.
Unlocking renewable energy potential
The initiative comes at a time when Central Asian countries are setting increasingly ambitious renewable energy targets, albeit at different scales and speeds
Kazakhstan currently operates 169 renewable energy facilities with a combined installed capacity of approximately 3.7 gigawatts. The governmentplans to add10 gigawatts of renewable capacity by 2035 underan initiativecalled QaJET, a national Energy Transition Investment Platform
Several large-scale renewable energy projects are already underway, including developments byMasdarin the Zhambyl Region, projects involving Energy China in the Karagandy Region and a planned project by China Power International Development in the Pavlodar Region
In 2025, nine new renewable energy facilities with a combined capacity of 503 megawattswere commissioned. These included five wind farms totaling 387 megawatts, three solar power plants with 90 megawatts, and one hydroelectric power plant with a capacity of 26 megawatts. The share of renewable energy generation reached 7% in the total energy balance.
Uzbekistan’s export potential
Against that backdrop, Uzbekistan’s rapidly expanding renewable sector could become a key some of the region’s most ambitious renewable energy targets.
Under its national strategy, the country aims to increase installed renewable energy capacity to 35 gigawatts by 2030. Renewables are expected to account for 54% of electricity generation by the end of the decade
In Uzbekistan, total capacity rose sharply from 6.1 gigawatts to 10 gigawatts in 2025, a 65% increase in a single year, according tothe International Renewable Energy Agency.The share of renewables in electricity capacity increased from 27.5% to 36.1%, highlighting the rapid scaling up of clean energy deployment
Azerbaijan as a gateway
Azerbaijan is expected to serve as the corridor’s gateway to European markets. The country is already working with Georgia, Romania and Hungary on a 1,500-kilometer Black Sea electricity transmission project that could ultimately provide the route through which renewable electricity generated in Central Asia reaches European consumers
Azerbaijan itself currently operates 65 hydropower plants, six wind farms and nine solar power plants, giving the country more than two gigawatts of renewable energy capacity. According to data from the Energy Ministry of Azerbaijan, renewables account for around one-fifth (20.8%) of total installed electricity capacity
Speaking at a ministerial roundtable during Kazakhstan Energy Week in October 2025, Azerbaijani Energy Minister Parviz Shahbazov said renewable energy cooperation is central to broader efforts to strengthen ties across Central Asia, the South Caucasus and the Caspian region
“The development of cooperation in the field of renewable energy occupies an important place in the policy of transforming Central Asia, the South Caucasus, and the Caspian region into a unified geopolitical space and strengthening strategic partnership and allied relations between our countries,” Shahbazov said.
“The creation of the Trans-Caspian Green Energy Corridor, which will connect the electricity systems of our countries for the first time in history, is fully consistent with the main priorities of this policy and opens up wide opportunities for the development of the Middle Corridor connecting Europe with Asia and China through the Caspian Sea as a green bridge,” he added
The project, overall, aligns with Europe’s broader push to diversify energy supplies and increase imports of low-carbon electricity as countries seek to meet decarbonization targets and strengthen energy security
Balancing ambitions
For Kazakhstan, however, one of the key challenges is mounting pressure on its domestic power system. According to an S&P Global report released in March, rising electricity demand and a shortage of flexible generation capacity needed to balance intermittent renewablets, particularly from Russia
The report notes that Kazakhstan’s electricity imports from Russia more than doubled in 2023 compared with the previous year, reflecting a shift from occasional cross-border exchanges to a more structural balancing relationship.
For the 2025-26 heating season, Kazakhstan is expected to face monthly electricity shortages ranging from 125 million to 330 million kilowatt-hours, with imports from Russia and Uzbekistan helping to bridge the gap
Whether the corridor ultimately becomes a major export route for Central Asian electricity will depend on more than political agreements. The participating countries need to determine the project’s cost, upgrade their power grids, expand renewable generation and secure a an ambitious project whose commercial and technical feasibility has yet to be proven
