Underground, layer by layer

What lies at each depth beneath Uzbekistan, and who is already using it.

  1. Ground level

    The surface

    Across most of the country, rock warms by up to about 20–30 °C for every kilometre of depth. YuzNews, 2021

  2. First 200 m

    Heat pumps

    The shallow ground keeps a steady temperature all year. Since 2025, a polyclinic in Urganch district, Khorezm, heats with it instead of gas. Story

  3. 135–300 m

    Altynsai, Navoi region

    Six wells bring up water at 68–70 °C, far hotter than depth alone would suggest. Two sanatoriums use it for treatment, heating, hot water and greenhouses. Story

  4. 2.5–3.5 km

    Gissar region

    Possible reservoirs for a first geothermal power plant: binary-cycle units built in 50 MW stages, up to 100 MW. Story

  5. 3–4 km

    Artesian basins

    Deep aquifers hold water at 50–100 °C, warmest in the Bukhara and Syrdarya regions: heat for buildings, greenhouses and fish farms. YuzNews, 2021

  6. 4–6 km

    Hot dry rock

    Petrothermal resources are cited beneath the Amu Darya basin, the South Aral area, the Kyzylkum and the Chust–Adrasman anomaly. Projected resources to 5–6 km are four to six times those of hydrocarbons. Story YuzNews, 2021

  7. 5 km and deeper

    Superhot rock

    Modelling suggests that developing just 1% of Uzbekistan’s superhot rock could supply about 98% of the electricity the country used in 2021. Story

Hot to cool

Every use of geothermal heat needs a different temperature. Ordered from hottest to coolest, one well can serve several in turn.

  • 100 °C and above

    Electricity

    Binary-cycle plants turn hot water into steady, around-the-clock power.

    In Uzbekistan: Researchers have outlined a 100 MW plant for the Gissar region. Story

  • 60–100 °C

    Heating

    Hot water heats buildings directly or through district heating networks.

    In Uzbekistan: Altynsai’s 68–70 °C water heats two sanatoriums in Navoi region. Story

  • 40–80 °C

    Greenhouses

    Warm water keeps greenhouses growing through winter without burning gas.

    In Uzbekistan: From November 2026, greenhouses heated by heat pumps or geothermal energy get half their winter electricity costs covered. Story

  • 35–70 °C

    Spas and sanatoriums

    Mineral thermal water has long been used for treatment and bathing.

    In Uzbekistan: Altynsai in Navoi region, Altyaryk in Fergana and Zangiota near Tashkent. Source

  • 20–30 °C

    Fish farming

    Thermal water at the right temperature lets fish farms grow all year.

    In Uzbekistan: Researchers link geothermal water to the national aquaculture programme. Source

  • 10–20 °C

    Heat pumps

    The shallow ground’s steady temperature heats buildings in winter and cools them in summer.

    In Uzbekistan: A polyclinic in Urganch district, Khorezm, since 2025, and now subsidised for household greenhouses near Tashkent. Story
