A Modern 650 MW Combined Cycle Power Plant Under Construction at Novoiust TPP in Uzbekistan

Tashkent, Uzbekistan (UzDaily.com) — Uzbekistan continues to implement large-scale energy projects aimed at increasing the capacity and reliability of the national power system.

One of the largest projects is the construction of a modern 650-megawatt combined cycle power plant (CCPP) at the Novoiust Thermal Power Plant, carried out with the support of the Japan International Cooperation Agency (JICA).

The general contractor is the Japanese corporation Mitsubishi, which is building the plant’s third CCPP. Construction began in 2024, and currently about 2,000 specialists are working on site, including 1,700 local and 300 foreign engineers and technicians. The project involves 178 units of specialized equipment.

The total project cost is estimated at US$768 million. Once operational, the plant will provide permanent employment for 256 people.

The facility includes a “J”-type gas turbine with a capacity of 489 megawatts, producing 200 gigacalories of heat per hour—half as steam and half as hot water. The plant’s efficiency will exceed 60%, and the water-saving and environmental control technologies applied meet modern international standards.

The construction includes buildings and structures for housing steam and gas turbines, generators, boilers, and other primary and auxiliary equipment. Units from leading global manufacturers from India, China, South Korea, Japan, and other countries are being installed.

In parallel, a 500 kV outdoor switchgear (OSG) is being constructed. Modern European equipment has already been delivered, including two autotransformers, seven SF6 circuit breakers, 12 surge protection devices, and 23 disconnectors.

The full commissioning of the new CCPP is scheduled for the third quarter of 2026. After the completion of all installation and commissioning stages, voltage will be supplied to the power unit through the substation, enabling automated monitoring and control of its operation.

In the first half of 2025, the Novoiust TPP generated 4.16 billion kWh of electricity, exceeding planned targets. Thermal energy production reached 526,000 gigacalories compared to the planned 455,000.

With the introduction of the new energy capacities, electricity production is expected to increase significantly, fully meeting the growing needs of the population and industry in the region.
