New HRSG Contract for a New Combined Cycle Power Plant in Greece

After an order awarded end of April by the same client, John Cockerill Energy has signed a new contract with Ansaldo Energia for the design and supply of a heat recovery boiler installed behind a AE94.3A GT for the new combined cycle power plant of Ptolemais, in Western Macedonia (Greece).

This power plant previously operated as a 660 MW coal-fired facility. It will be replaced by a new, high-efficiency 460 MW combined cycle plant. The project will significantly contribute to Greece’s energy transition, energy independence, and decarbonization, supporting the planned conversion from lignite to natural gas in Western Macedonia.

Operated by Public Power Corporation S.A. (PPC), Greece’s main electricity provider, the new power station will reduce fuel consumption, lower operating costs, and contribute to a significant reduction in CO₂ emissions. In addition, its increased ramp rate will enable rapid response to grid fluctuations linked to the growing penetration of renewable energy.

As part of its ambition to become coal-free by 2026, PPC is transitioning from a coal-heavy national utility to a low-carbon, regional, technology-driven energy group, using natural gas as a bridge technology. This new combined cycle power station will supply electricity to approximately 900,000 households in the region.

This order reflects the consistency of our engagement, combining strong technical expertise with a trusted customer relationship. Our client has once again placed its trust in John Cockerill: this HRSG will be the fifth unit designed and supplied to Ansaldo Energia by our Belgian teams, following previous orders for power plants in Tunisia and Hungary.
