Uzbekistan Wants Nuclear Energy, But Can It Afford the Water Cost?

Why It Matters

The NPP promises energy security and economic growth, but its water‑intensive operation threatens to deepen Uzbekistan’s acute water scarcity and create long‑term financial and environmental liabilities.

Key Takeaways

• Uzbek NPP aims to supply 15% of national electricity
• Project valued at $24.7 billion, deepening Russian ties
• Plant could use >70 million m³ water annually
• Water stress already 123%; cooling adds major strain
• Dry‑cooling can cut water use up to 90%

Pulse Analysis

Uzbekistan’s decision to pursue nuclear power reflects a strategic response to a projected 40% rise in Central Asian electricity demand by 2030. The Jizzakh plant, built with Russian expertise and IAEA oversight, is positioned as a long‑term anchor for industrial growth, promising to offset natural‑gas consumption and diversify the nation’s energy mix. Yet the scale of the investment—nearly $25 billion—signals a deepening reliance on Russian fuel supply, maintenance contracts, and technical know‑how, raising questions about economic sovereignty and risk exposure.

Water scarcity is the Achilles’ heel of the project. The country already faces a water‑stress index of 123%, meaning demand outstrips supply. Cooling a nuclear reactor typically consumes tens of millions of cubic metres of water each year; estimates for the Uzbek site exceed 70 million m³, comparable to a midsize city’s annual use. While dry‑cooling technology can slash water demand by up to 90%, it does not eliminate the need for reliable cooling infrastructure and may increase capital costs. In a basin already losing up to 92% of its volume, additional thermal discharge could accelerate ecosystem degradation in the Aral Sea region.

Beyond the environmental calculus, the venture carries substantial financial and geopolitical risk. Global nuclear projects often suffer cost overruns that double original budgets, leaving taxpayers to shoulder the burden. Russia’s role extends beyond construction to fuel supply and long‑term operation, embedding a strategic dependency that could limit Uzbekistan’s policy flexibility. Moreover, the establishment of a national radioactive‑waste centre imposes decades‑long monitoring obligations. Integrating water‑energy planning, investing in dry‑cooling, and developing domestic nuclear expertise will be essential to ensure the plant’s benefits outweigh its hidden costs.
