Provincial Energy Interconnection with Central Asia

Central Asia is actively enhancing regional energy interconnections to optimize electricity trade, integrate renewable energy, and strengthen energy security across Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan.Current State of Energy InterconnectionsThe Central Asian Unified Energy System (CA UES) currently operates in parallel among Kazakhstan, Kyrgyzstan, and Uzbekistan, while Tajikistan and Turkmenistan have historically operated autonomously . Tajikistan is undergoing reconnection to the CA UES through Uzbekistan's Southern grid, with projects like the Guzar-Regar and Surkhan-Regar lines and a new 500 kV line between the New Syrdarya TPP (Uzbekistan) and Sughd SS (Tajikistan), expected to be completed in 2024 . These interconnections allow seasonal electricity trade, with hydro-rich countries exporting in summer and importing in winter.Strategic Roadmap and Policy FrameworksRegional stakeholders, guided by ESCAP and UNECE, are developing a roadmap for energy connectivity that emphasizes renewable energy integration, electricity trade expansion, and institutional alignment . Key strategies include financing new renewable power plants, refurbishing hydropower facilities, and strengthening regulatory frameworks to support sustainable energy transitions. Stakeholder engagement is critical to ensure technical, political, financial, and social factors are aligned for effective regional integration .Opportunities and ChallengesCentral Asia possesses significant energy resources, including hydropower, natural gas, solar, and wind, which can support both regional and European electricity demand . However, the region remains underconnected, limiting the full potential of electricity trade and renewable energy integration . High fossil fuel subsidies in countries like Kazakhstan can distort market signals and delay clean energy adoption . Scaling up interconnections and trade could reduce costs, optimize renewable energy deployment, and attract international investment .International CooperationThe European Union and other global actors, including the World Bank and ADB, are supporting technical studies, financing, and infrastructure projects to enhance cross-border electricity transmission . Optimal transmission routes are being evaluated using GIS-based cost mapping to identify least-cost paths for electricity export to Europe while maximizing regional benefits . These efforts aim to improve energy security, facilitate renewable energy integration, and support economic growth across Central Asia.Key Projects and InvestmentsFlagship projects include the Rogun Hydropower Project in Tajikistan, Kambarata-1 in Kyrgyzstan, and large-scale solar and wind parks in Kazakhstan and Uzbekistan . Expanding electricity exchanges and strengthening interconnections will enable these projects to achieve economies of scale, enhance regional energy trade, and support the clean energy transition .ConclusionProvincial energy interconnection in Central Asia is a strategic priority for regional energy security, economic growth, and renewable energy integration. By completing key transmission projects, aligning policies, and fostering international cooperation, Central Asian countries can unlock the full potential of their energy resources, optimize electricity trade, and contribute to a sustainable and interconnected regional energy system .
