Pomerania becomes a strategic energy hub

Construction works on the CCGT Gdańsk combined-cycle gas turbine power plant have entered an increasingly advanced stage, confirming the growing role of northern Poland in the country’s long-term energy transformation strategy.

The investment, developed by Energa Group, goes far beyond a regional infrastructure project. It is one of the most important energy investments currently underway in Poland and a key component of the modernization of the national power system.

The new gas-fired unit in Gdańsk, with a net capacity of approximately 560 MW, will become the first large-scale system power source in the Pomeranian region. For decades, northern Poland lacked major dispatchable generation assets capable of stabilizing the national grid.

Together with the CCGT units currently under construction in Grudziądz and Ostrołęka, the Gdańsk project forms part of a broader restructuring of the Polish power generation landscape. The four gas-fired units developed by Energa Group will provide a combined installed capacity of around 2.4 GW, enough to supply electricity to nearly 5.5 million households annually.

A strategic pillar of Poland’s energy security

Government officials and energy sector executives emphasize that flexible gas-fired generation is becoming essential for maintaining the stability of Poland’s evolving power system.

According to Poland’s Ministry of Energy, modern combined-cycle gas turbine units offer the flexibility, availability, and operational stability required to support a rapidly growing share of renewable energy sources.

This flexibility is particularly important as Poland accelerates investments in offshore wind and photovoltaic capacity. Unlike conventional coal-fired plants, CCGT units can start up quickly and dynamically adjust output depending on fluctuations in renewable generation.

For the Pomeranian region, the project carries additional strategic significance. Northern Poland is increasingly becoming a center for offshore wind development, new transmission infrastructure, and balancing capacity for the national grid.

Energa SA President Magdalena Kamińska noted during the cornerstone ceremony that Poland’s energy map is being redrawn, with northern regions gaining a much stronger role in balancing electricity production and securing energy supplies.

Supporting the offshore wind revolution

CCGT Gdańsk is expected to play a crucial role in supporting the integration of renewable energy into Poland’s power system.

Combined-cycle gas turbine plants are widely regarded as a transitional technology that can bridge the gap between coal-based generation and a future low-emission energy system dominated by renewables.

Compared with coal-fired units, modern gas plants offer significantly lower carbon emissions while maintaining the ability to provide stable and dispatchable power when renewable production declines.

According to Grzegorz Błędowski, President of CCGT Gdańsk, the plant is expected to generate more than 43 TWh of electricity during its first 20 years of operation. On an annual basis, the facility will be capable of supporting over one million households during periods of lower renewable output.

This capability will become increasingly important as offshore wind farms in the Baltic Sea continue to expand. The growing volume of intermittent renewable generation will require fast-reacting balancing assets capable of stabilizing the electricity system.

Construction accelerates on site

The construction site in Gdańsk is already witnessing intensive groundwork and structural operations. Basic utility connections have been completed, internal roads are being built, and auxiliary OSBL (Outside Battery Limits) infrastructure is under development, including the raw water supply system necessary for future plant operations.

One of the most advanced stages currently underway involves the installation of specialized foundation piles designed to strengthen the ground beneath key structures.

Piling works for the turbine hall and the turbine-generator set foundations have already been completed. The complete turbo-generator system, including both turbines and the generator, will weigh more than 1,000 tons.

Construction teams are now carrying out piling works for the Heat Recovery Steam Generator (HRSG) foundations. Individual piles will reach diameters of up to 60 centimeters and depths of as much as 25.4 meters.

Importantly, the project uses drilling technology rather than traditional pile-driving methods in order to minimize noise and vibrations affecting nearby communities and industrial facilities.

Following drilling operations, the boreholes are filled with concrete, which then requires approximately one month to cure before load testing and continuity inspections are performed.

The first major foundation works are scheduled to begin in the second half of 2026.

Siemens Energy to deliver the plant’s core technology

The key technological components of the power plant will be supplied by Siemens Energy.

The company will deliver the gas turbines and generators that will form the operational core of the new unit. Delivery of the main turbine-generator package is expected in 2027.

The same technology platform will also be implemented at Energa Group’s CCGT projects in Grudziądz.

Grzegorz Należyty, President of Siemens Energy Poland, emphasized that modern CCGT technology combines high efficiency with exceptional operational flexibility.

This allows the power plant to respond rapidly to changing grid conditions and provide critical backup capacity whenever renewable generation decreases.

Modern combined-cycle units are currently among the most efficient conventional technologies used in utility-scale power generation, offering both lower emissions and improved economic efficiency.

Strong impact on Polish industry

Beyond its energy significance, CCGT Gdańsk is also expected to generate substantial economic benefits for Poland’s industrial and construction sectors.

The project is being executed by a consortium led by Polimex Mostostal, one of Poland’s leading energy construction companies.

According to company representatives, approximately 80 percent of project expenditures are expected to remain within the Polish market. Around 150 domestic subcontractors and suppliers will participate in the investment.

At peak construction activity, the site will employ nearly 700 workers, while the entire project is expected to generate approximately three million man-hours.

Once operational, the power plant will employ around 60 highly qualified specialists.

The growing role of local content in strategic energy projects has become one of the defining trends of Poland’s industrial policy. The energy transition is increasingly viewed not only as a technological transformation, but also as an opportunity to strengthen domestic industrial capabilities and engineering expertise.

Gas-fired power as a transitional solution

The development of CCGT units remains one of the central pillars of Poland’s energy transition strategy.

In the coming years, the country’s power system will face rising electricity demand alongside the gradual decommissioning of aging coal-fired assets.

At the same time, the growing share of intermittent renewable generation will require stable and flexible balancing capacity.

In this context, gas-fired units are widely perceived as a practical transitional solution that enables the gradual shift toward a low-emission economy.

Compared with coal-fired plants, CCGT facilities offer lower emissions while maintaining the operational flexibility required to cooperate effectively with renewable energy sources.

For northern Poland, the strategic importance of these investments will continue to increase as offshore wind development accelerates across the Baltic Sea.

A new energy era for northern Poland

CCGT Gdańsk symbolizes a broader transformation currently reshaping Poland’s energy sector.

The project is not simply another power plant under construction. It is part of a comprehensive restructuring of the country’s energy infrastructure, with northern Poland emerging as one of the key centers of electricity generation and system balancing.

Through investments such as CCGT Gdańsk, Energa Group is helping to position Pomerania at the forefront of Poland’s modern energy economy — integrating offshore wind, flexible gas-fired generation, and advanced transmission infrastructure.

The scale of the project, the involvement of domestic industry, and its strategic importance for national energy security make CCGT Gdańsk one of the most significant energy investments currently underway in Poland.
