GE Vernova’s H-Class Equipment Package Powers Polish Combined-Cycle Plant

Polska Grupa Energetyczna’s (PGE) 1.4-GW Gryfino Dolna Odra power plant entered commercial operation following the delivery and installment of GE Vernova’s HA combined-cycle equipment. Located in Poland’s Western Pomerania region, the plant was built by Polimex Mostostal and will provide the electricity equivalent to power three million Polish households. GE Vernova also signed a 12-year service agreement to manage the project lifecycle, training, and maintenance, supporting operational performance and reliability.

“To support Poland’s climate and energy transition agenda, as more coal fired plants are retired, the need to add more reliable and flexible power that provides greater grid stability is essential,” said Joseph Anis, President & CEO of GE Vernova's Gas Power business in Europe, Middle East & Africa. “H-class power plants like PGE Gryfino Dolna Odra have a lower emissions impact with up to 60% less emissions compared to other plants of the same size powered by diesel, coal and other fossil fuels. The project represents a milestone for Poland, adding to the system a large-capacity plant that can bring stability to the country's electricity matrix, and we are pleased our collaboration with PGE proved to be effective.”

GE Vernova equipped PGE’s combined-cycle plant with two 683-MW blocks, each containing:

• 9HA.01 gas turbine
• STF-D650 steam turbine
• W88 generator
• Once Through heat recovery steam generator (HRSG)

The Once Through HRSG enables advanced water-steam cycles to deliver higher combined-cycle efficiency. The steam turbines and generators for Gryfino Dolna Odra were manufactured in GE Vernova’s Poland-based factories in Elblag and Wroclaw.

"The commissioning marks the completed construction of the largest gas-fired power plant in Poland – PGE Gryfino Dolna Odra with a total capacity of 1,366 MW,” said Dariusz Marzec, President of the Management Board of PGE. “The new gas units will replace the old and inefficient coal units at the Dolna Odra Power Plant, thus aligning with PGE Group's strategy for decarbonizing its generation assets. Thanks to its flexibility, meaning the ability to start up quickly and adjust the volume of energy produced, the investment in Gryfino will help meet market demands and assist in stabilizing the power grid in Poland and optimizing the use of variable energy production from renewable sources."

Previous Work in Poland

In 2023, GE Vernova agreed to modernize PGE’s Porąbka-Żar Pump-Storage power plant—the second largest plant of its kind in Poland with an installed capacity of 500 MW. The company will provide four 125-MW pumped-storage turbines and generators to replace existing hydro assets, increasing the hydropower plant’s efficiency and lifetime over several decades.

Last week, Guangdong Energy Group’s (GEG) Dongguan Ningzhou combined-cycle power plant entered operation in Guangdong province, China, with GE Vernova’s H-class technology. The plant is powered by three 9HA.02 gas turbines and is expected to add up to 2.4 GW of power to China’s national grid, in addition to the 1.34 GW of power already provided by the HA-equipped Huizhou power plant. Leveraging natural gas via GE Vernova’s H-class technology, GEG’s power plant has a lower emissions impact with up to 60% less carbon emissions compared to similarly sized plants powered by coal.
