Doosan Škoda Power Obtains Modernization, Turbine Supply Contract for Opatovice

Doosan Škoda Power won a contract to modernize Unit TG6 at the Opatovice Power Plant, including the supply of a new condensing turbine and condenser, repair of the current generator, installation of new district water heaters, and a solution for piping and steel structures. The contract builds upon Doosan’s two prior successful deliveries and contributes to Opatovice’s ongoing decarbonization transformation.

“I am proud that we have succeeded for the third time—following the successful projects for Units TG5 and TG3, we have now also secured TG6,” said Tomáš Bayer, Area Sales Director for Europe at Doosan Škoda Power. “Thanks to this, the entire fleet of existing modernized Opatovice steam turbines will now bear the Doosan Škoda Power brand.”

The project arrives as an engineering, procurement, and construction contract: a turnkey solution encompassing all aspects such as design, manufacturing, civil works, installation, and commissioning. Opatovice Power Plant’s modernization will progressively eliminate coal-fired operations and install more efficient, environmentally friendly gas-fired combined cycle operations. Doosan will renew steam turbines in the TG machine hall, which are currently designed to operate in both coal- and natural gas-fired modes.

“The most challenging aspect was devising a comprehensive solution that would both increase the operational efficiency of Unit TG6 and respect the spatial limitations of the existing machine hall,” said Ladislav Szőcs, Sales Manager at Doosan Škoda Power. “A crucial factor was also the need to adhere to a very demanding schedule for the planned outage of the district water heating system.”

The plant produces significant amounts of electricity and heat in the East Bohemia region, supplying heat to approximately 63,000 customers in Pardubice, Hradec Králové, Chrudim, and additional towns and municipalities across the area. Doosan Skoda Power—based in Pilsen—was awarded the first modernization contract in 2019 for the plant’s first cogeneration unit. It was executed during a planned outage in 2020, with equipment handed over for permanent operation prior to autumn 2020. The initial project focused on Unit TG5, followed three years later by another contract to replace the TG3 turbine.

“Doosan Škoda Power has already supplied turbines for the first and third heating stages, which have been successfully commissioned and support combined heat and power generation,” said Jan Burýšek, Strategic Development Specialist at Opatovice Power Plant. “The power plant is now entering the final stage of machine hall modernization—the replacement of the TG6 turbine, which ensures the second heating stage and will also be ready for future combined-cycle operation. This contract was also awarded to the same supplier, ensuring technical uniformity across all three turbines and enhanced operational reliability for the entire system.”

Last month, Doosan Enerbility signed an agreement with a large-scale U.S. technology company to supply two 380-MW gas turbines by year-end 2026. This marks the company’s first overseas export of gas turbines, representing a significant milestone for the Korean power sector. Doosan Turbomachinery Services—the company’s Houston-based subsidiary—will handle gas turbine maintenance services.

In 2019, Doosan Enerbility partnered with the domestic, academia, and research sectors to successfully manufacture large-scale gas turbines for power generation. Next, the company performed over 15,000 hours of demonstration tests at the Gimpo Combined Heat & Power Plant, verifying the performance of domestically manufactured turbines. Doosan then secured multiple supplier agreements for eight total gas turbines.
