The Takhiatash thermal power plant is to be upgraded to meet rising electricity demand in the western part Uzbekistan. The project will involve building two combined-cycle gas turbine units with a capacity of 230-280 MW, decommissioning old and inefficient power generation units, improving energy efficiency, and increasing power supply to the Karakalpakstan and Khorezm regions.
UzbekEnergo announced in December 2016 that the consortium including the South Korean Hyundai Engineering and Hyundai Engineering and Construction won the tender for the modernisation of Takhiatash Thermal Power Plant (TPP).
The consortium who won the international competition for the project "Construction of two 230-280 MW combined cycle power plants (CCPP) at at Takhiatash TPP" proposed a price of 457 million dollars and a 2.5 year build time. There were a total of 10 bidders from China, South Korea and Turkey. Hyundai winning the tender against strong competition from Turkey (Calik) and several China EPCs.
The project will cost a total of $ 678.2 million funded by a $ 300 million Asian Development Bank loan, US $ 230.7 million from the Fund for Reconstruction and Development of Uzbekistan and the rest from UzbekEnergo’s own funds.
The Takhiatash TPP is the main source of power supply in the Karakalpakstan and Khorezm regions. In 2012, power consumption in these regions was 2,293 mln. kilowatt-hours (kWh) with maximum load of 466 megawatts (MW). By 2020, the power consumption is expected to exceed 3,620 mln. kWh, with maximum load of 620 MW.
(ED: Note The term GRES (Russian: ГРЭС) refers to a condenser type electricity-only thermal power station introduced in the Soviet Union which still exist in Russia and other former Soviet republics. The Russian abbreviation ГРЭС stands for Государственная районная электростанция, or "state-owned district power plant" Over time the abbreviation has lost its literal meaning, and the term refers to a high-power (thousands of megawatt) thermal power station of condenser type. The term TEC or TETs (Russian: ТЭЦ, теплоэлектроцентраль) refers to combined heat and power plants).
