Central Asia's Energy Transition Depends on Water Security

Central Asia is building a new energy system where solar, wind, hydropower, and nuclear projects are increasingly connected by water security. Climate change is making hydrology less predictable just as electricity demand grows, exposing the region to water shocks. Deeper integration could reduce annual system costs by $3.5 billion by 2035, even as August 14 blackouts showed interconnection alone is not resilience.

Key Facts

Modeling by Agora Energiewende and the University of Central Asia suggests deeper integration between Kazakhstan, Uzbekistan, and Kyrgyzstan could reduce annual system costs by around $3.5 billion, or 18 percent, by 2035.
The World Bank's Regional Electricity Market Interconnectivity and Trade (REMIT) program aims to increase annual regional electricity trade to at least 15,000 GWh, expand transmission capacity to 16 GW, and enable up to 9 GW of clean energy.
Kazakhstan, Kyrgyzstan, Tajikistan, and Uzbekistan all reported blackouts on August 14.
Kazakhstan and Uzbekistan are both moving ahead with nuclear power.

Regional Energy Mix

Kazakhstan remains strongly dependent on thermal and coal-fired generation. Uzbekistan's system is still largely gas-based, although solar, wind, and battery storage are expanding rapidly. Kyrgyzstan and Tajikistan rely heavily on hydropower, while Turkmenistan relies predominantly on natural gas. These differences can create complementarity: hydropower and reservoirs provide flexibility for variable renewables, solar and wind reduce dependence on hydrology, and thermal generation offers firm capacity while storage expands.

Integration Economics

Cross-border electricity trade allows countries to draw on different resources rather than maintaining isolated systems. The World Bank's REMIT program targets annual regional electricity trade of at least 15,000 GWh and transmission capacity of 16 GW. Agora Energiewende and the University of Central Asia estimate integration could cut annual system costs by $3.5 billion, or 18 percent, by 2035.

Water Shock Exposure

Climate change is making Central Asia's hydrology less predictable just as electricity demand is growing. Drought can constrain hydropower, extreme heat can increase power demand, and irrigation systems consume large amounts of electricity. On August 14, Kazakhstan, Kyrgyzstan, Tajikistan, and Uzbekistan all reported blackouts, demonstrating that interconnection alone is not resilience.
