Uzbekistan is on the brink of a historic moment as it seeks to commission two VVER-1200 pressurized water reactors, scheduled for 2028 and 2030. The journey to build the country's first nuclear power plant has been a thorough one, with UzAtom, the state agency for nuclear energy, leaving no stone unturned in ensuring the project meets the highest international standards of safety.

In January 2023, an IAEA SEED mission team made a trip to Uzbekistan to review the country's safety processes for evaluating the site of the plant. The team of experts from France, Turkey, the UK and the IAEA, conducted interviews and made a visit to the selected site near Lake Tuzkan, in the Farishsky district.

The SEED mission found that Uzbekistan has carried out an objective and safety-oriented site characterisation process that puts the safety of workers, the public and the environment first. The IAEA team provided recommendations to support the optimisation of the site evaluation process.

The IAEA recommended that UzAtom collect the necessary data, according to guidelines provided in

SSR-1, and implement a management system that covers all aspects of site evaluation. It also recommended that UzAtom identify and select feasible engineering measures to provide plant cooling and site protection from external events, and finalize the Preliminary Safety Analysis Report.

Uzbekistan's journey to commission its first nuclear power plant is a testament to the country's commitment to meeting the highest international standards of safety. The IAEA's recommendations will ensure that these standards are literally implemented from the ground up in the siting and construction of the plant. The final mission report will be delivered to the government of Uzbekistan within three months, marking the next step in this exciting journey.


Steps in siting a nuclear plant:

Site selection and assessment

Data collection on seismological, hydrological, meteorological and environmental parameters

Integrated Nuclear Infrastructure Review mission

SEED Review Service mission

Review of site data collection methods

Identification of external hazards

Reorganizing existing data and collection of additional data

Implementation of a management system covering site evaluation

Selection of feasible engineering measures for plant cooling and site protection

Finalization of the Preliminary Safety Analysis Report

Consideration of all recently collected site-specific data

Well-informed decision making related to construction licensing, investments and safety assessment phases.

Geothermal Energy Costs: Why Drilling Discipline Decides Bankable Megawatts

Geothermal Isn't Expensive: The Reservoir Always Has the Final Say Somewhere beneath a volcanic ridge, a drill bit is turning through rock that has not moved in two million years. It costs money every second it turns. And nobody on the surface — not the engineer, not the financier, not the minister who announced the megawatts — knows yet whether that well will produce steam or silence. That single moment explains almost everything people get wrong about geothermal energy. Geothermal is routinely described as expensive, slow, capital-hungry and haunted by drilling risk. Investors are reminded that tens of millions can disappear underground before a single megawatt reaches a grid. All of that is true. But it is not the whole truth. The uncomfortable question the industry keeps avoiding is this: is geothermal expensive, or is the way we develop geothermal making it expensive? Those are two completely different problems. One is geology. The other is us. Why Geothermal Refuses to Be...

BLM Utah 2026 Geothermal Lease Sale Opens New Energy Opportunities

BLM Utah 2026 Geothermal Lease Sale: What It Means for U.S. Geothermal Development The Bureau of Land Management’s Utah 2026 Geothermal Lease Sale is a significant signal for the next phase of U.S. geothermal development. As federal agencies continue to prioritize renewable energy on public lands, this project highlights both the practical mechanics of geothermal leasing and the broader policy direction supporting domestic clean energy expansion. For developers, investors, land managers, and energy analysts, the sale offers an important case study in how geothermal projects move from planning into commercial opportunity. Geothermal energy has long been one of the most promising yet underutilized renewable resources in the United States. Unlike solar and wind, geothermal can provide steady baseload power regardless of weather or time of day. That makes it especially valuable in power systems that need reliability, grid stability, and long-duration decarbonization. A lease sale like the ...

DOE Launches Geothermal Center of Excellence to Accelerate U.S. Deployment

DOE launches Geothermal Center of Excellence to push U.S. geothermal toward gigawatt scale The U.S. Department of Energy has launched a new Geothermal Center of Excellence in Golden, Colorado, with a clear mandate: connect industry with the national labs, accelerate geothermal innovation, and help move the technology toward gigawatt-scale deployment. The center is part of DOE’s effort to position geothermal as a more competitive source of reliable baseload electricity in the United States.  The announcement matters because it comes at a time when geothermal is gaining fresh attention from policymakers, developers, and power buyers, especially as data centers and industrial users look for firm clean electricity. DOE says the U.S. already leads the world in geothermal electricity capacity at just over 4 GW, but that current output represents only a fraction of the country’s technical potential. [1] Why DOE created it DOE says the new center is designed to become industry’s main en...

EIG Geothermal Catalyst Partners Launches Inaugural Power Planet Investment

EIG’s First Geothermal Bet Signals a New Phase for EGS Financing Image : Thematic image of a geothermal plant EIG Geothermal Catalyst Partners’ inaugural investment in Power Planet is a meaningful signal for the geothermal sector because it links development capital with a project that already has infrastructure, interconnection capacity, and subsurface data on its side . For an industry that often struggles to move from concept to bankable execution, that combination can shorten timelines and reduce risk. Why This Deal Matters The core story is not just that EIG made its first investment; it is that the fund is targeting the middle of the geothermal value chain, where projects need capital to clear technical and commercial hurdles . That matters because enhanced geothermal system, or EGS, projects can be highly promising but capital-intensive, especially before they reach a stage where traditional infrastructure investors feel comfortable stepping in . Power Planet’s Star Peak proje...

The Geopolitics of Critical Minerals: Who Controls the Geothermal Brine Supply Chain?

The Geopolitics of Critical Minerals: Who Controls the Geothermal Brine Supply Chain? The geothermal brine supply chain is quickly becoming a geopolitics story, not just an energy story.  By: Robert Buluma As lithium demand rises and governments race to secure strategic materials, control over underground brines, processing capacity, and export rules may matter as much as who owns the power plant.  Introduction For years, geothermal projects were valued mainly for clean baseload electricity and heat. That is changing because many geothermal fields also contain dissolved lithium and other critical minerals, turning brine into a potential dual-purpose asset: energy plus minerals.  That shift matters because critical mineral supply chains are already highly concentrated, and Europe is actively trying to reduce reliance on single-country suppliers through the Critical Raw Materials Act.  China remains central to lithium processing and broader mineral refining, giving it...

The "Heat-as-a-Service" (HaaS) Business Model: Geothermal Without the CAPEX Nightmare

Heat-as-a-Service takes geothermal from a capital-intensive power project to a financeable, contract-based heat utility: instead of selling electrons, you sell stable, decarbonized heat under long-term contracts that match what industrial customers and investors actually want. Image: A thematic picture of a geothermal power plant By shifting risk and ownership away from end users and toward specialised developers and infrastructure capital, it can unlock geothermal in markets where electricity tariffs are low but demand for reliable, low-carbon process heat is strong. From kWh to “heat-as-a-service” Traditional geothermal projects earn revenue by selling electricity into a grid, often at wholesale prices that barely cover high up-front drilling and plant costs unless there is a feed-in tariff or premium.Many industrial users, however, do not need electricity; they need heat for processes like brewing, greenhouse climate control or pulp and paper production, and they currently buy that ...

Policy, Investment and Corporate Offtake Trends Driving Next‑Gen Geothermal Energy Growth (2026–2030)

Policy and Investment Landscape for Next-Gen Geothermal in 2026–2030 Why 2026 Matters Next-generation geothermal is moving from promising concept to investable infrastructure. The combination of policy support, corporate demand, and better drilling technology is making the sector more relevant to investors and decision-makers.

Europe’s New Geothermal Push Europe is tightening permitting and improving geothermal rules to speed up deployment. Germany is especially active, while EU-level reforms are pushing for shorter approval timelines and better risk-sharing tools. Emerging Market Openings Countries like Kenya, Indonesia, the Philippines, Chile, and Türkiye are becoming important growth markets. Their combination of strong geothermal resources and rising po...

How AI-Powered Digital Twins Are Transforming Geothermal Reservoir Management

Geothermal Reservoir Digital Twins: How AI Is Transforming Reservoir Management Image : Thematic image of a geothermal heat pump Artificial intelligence and digital twins are quietly rewriting the playbook for geothermal reservoir management. They turn scattered subsurface data into living, predictive models that help operators boost output, cut drilling risk, and extend the productive time. How Geothermal Digital Twins Are Making Reservoirs Smarter, Safer, and More Profitable For decades, geothermal development has been constrained by one brutal fact: you can’t see 3 km underground. You infer, you model, you hope—and sometimes you drill into a dry or underperforming reservoir. AI‑powered geothermal digital twins change that equation by continuously updating subsurface models with real‑time data, making the invisible reservoir behave like a transparent, responsive system. In practice, geothermal digital twins are dynamic software replicas of wells, reservoirs, and surface facilities th...
