H-Class combined cycle plants to replace coal at Kozienice
GE Vernova has received an order from Enea Group for two 9HA.01 gas turbine combined cycle blocks to support Enea’s gradual replacement of coal-fired power generation produced at Kozienice station and help support Poland’s energy transition. With this order GE Vernova says its H-Class fleet has surpassed 200 units. This project is in line with the Enea Group’s Development Strategy 2035 and forms part of the company’s energy transition plan. Implementation of the strategy is expected to reduce the Group’s emissions by 64% by 2035, with Enea aiming to become a fully climate- neutral company by 2050.
For the Kozienice power plant, the two blocks, will each include, in addition to the 9HA.01 gas turbine, an STF-D650 steam turbine, a W88 generator, integrated Mark* VIe distributed control system and a three-pressure-level-with- reheat heat recovery steam generator. The steam turbine and the generator will be manufactured locally, in Poland, in GE Vernova’s factories in Elblag and in Wroclaw, respectively, while the gas turbine will be manufactured at GE Vernova’s Manufacturing Excellence Center in Belfort, France.

The engineering, procurement, and construction (EPC) contractor is Calik Enerji. It is estimated that the involvement of Polish companies in the project will reach around 75%. “Poland is poised to emerge as a model nation for the energy transition, as it stands on the brink of rapidly diversifying its energy sources,” said Joseph Anis, President & CEO for GE Vernova’s Gas Power business in Europe, Middle East & Africa.

Jafurah CHP goes commercial GE Vernova has also announced that the Jafurah Cogeneration Independent Steam and Power Plant (ISPP), employing the first HA to be manufactured in Saudi Arabia, has achieved commercial operation. The plant is located about 125 km southeast of Dammam, Saudi Arabia. GE Vernova provided the core power plant equipment, the 7HA.01 gas turbine, and a service agreement for 20 years, including maintenance and supply of parts aiming to manage all aspects of the engine’s lifecycle. The plant is expected to deliver up to 314 tons/hour of steam, as well as up to 320 MWe, to support Jafurah gas field operations. Mitsubishi Power has recently announced inauguration of the first-ever JAC gas turbine to be assembled in Saudi Arabia, at its Dammam assembly facility. The M501JAC gas turbine will be delivered to the 475 MW Amiral cogeneration plant in Jubail, Eastern Province, which will supply electricity and steam to the Saudi Aramco Total Refining and Petrochemical Company (SATORP) strategic petrochemical complex.
Xcel opts for open cycle F class
In a major step toward strengthening grid energy reliability across its southwest service territory, Xcel Energy has purchased ten large gas turbines and associated generation equipment from Siemens Energy to support construction of two open cycle power plants. The investment comes as electric demand surges across the region, driven by evolving energy needs and the planned retirement of Xcel Energy’s Tolk station. The new facilities will add 2088 MW of dispatchable capacity, ensuring flexible, on- demand power.
“As demand for reliable energy grows, dispatchable power is no longer optional,” said
Luke Baker, Head of Gas Services Sales, North America, at Siemens Energy. “Our turbine technology ensures availability and flexibility in a region critical to America’s energy future.” At Tolk station in Muleshoe, Texas, Xcel Energy will retire its coal plant and install five Siemens Energy SGT6-5000F gas turbines and five SGen6- 1000A generators, delivering 928 MW of backup energy to support grid stability.
In Gaines County, a new peaker plant will be built to rapidly generate electricity during high demand periods. It will feature five additional F-class turbines and five generators, adding 1160 MW of fully dispatchable capacity.
“These power plant projects are part of a broader portfolio that includes 17 new power initiatives and more than 5000 MW of added capacity by 2030,” said Adrian J. Rodriguez, president, Xcel Energy – Texas, New Mexico.
The first turbine deliveries are scheduled for early 2026, with anticipated commercial operation dates aligned to meet Southwest Power Pool’s increased regional planning reserve margin requirements. Siemens Energy says its SGT6-5000F gas turbine is designed for fast start-up and quick load changes.
