Poland’s Energy Transition Takes Flight: CPK Launches Market Consultations for 5th Generation Heating and Cooling Network

Poland’s Energy Transition Takes Flight: CPK Launches Market Consultations for 5th Generation Heating and Cooling Network

By :Robert Buluma

Warsaw, Poland – June 8, 2026 – In a significant step that transcends traditional transportation infrastructure, the company responsible for building Poland’s largest infrastructure project, Centralny Port Komunikacyjny (CPK), has officially initiated preliminary market consultations (Wstępne Konsultacje Rynkowe) for a highly advanced energy system. The focus is the development of Energy Centers (Centra Energetyczne) designed to power a 5th generation district heating and cooling network, a first-of-its-kind scale project in the Republic of Poland.

While the CPK program, now operating under the brand "Port Polska," is widely recognized for its planned mega-airport between Warsaw and Łódź and a 2,000 km integrated railway network, this latest announcement on June 8, 2026, signals a deeper strategic commitment. The company is positioning itself as a key driver of the country’s energy transformation, moving beyond mobility to become a prosumer-centric energy hub. The consultations, which run from July 1, 2026 (with applications due by June 30), aim to refine the technological and operational framework for a decentralized, low-carbon thermal system that will serve the new airport complex and its surrounding ecosystem.

This article provides a precise analysis of the 5th generation network, the scope of the market consultations, the technological requirements, and the strategic implications for Poland’s energy security and the CPK’s long-term sustainability goals.

The Genesis of the Project: Beyond the Airport

The Centralny Port Komunikacyjny is not merely a transfer point; it is designed as a smart, integrated city-state. The sheer scale of the planned development—a new airport initially handling 40 million passengers annually, expanded railway junctions, maintenance depots, cargo terminals, and associated real estate—presents an immense energy demand. However, the project’s philosophy moves away from simply meeting peak loads with fossil fuels.

According to the press release published on CPK’s official platform, the "Port Polska" investment program is undertaking the largest project of this specific type in Poland. The core of this initiative is the deployment of a 5th generation district heating and cooling (5GDHC) network.

Unlike conventional district heating (3rd and 4th generation), which relies on high-temperature water (often 80-120°C) produced by centralized combined heat and power (CHP) plants or boilers, a 5th generation network operates at near-ground temperatures (typically 5-25°C). This allows it to function as a bi-directional thermal loop.

How the 5th Generation Works

The press release explicitly describes the mechanism: "Piąta generacja sieci ciepłowniczych polega na wymianie ciepła i chłodu pomiędzy budynkami o różnych bilansach energetycznych" (The fifth generation of heating networks involves the exchange of heat and cold between buildings with different energy balances).

This is a fundamental paradigm shift. In a 5GDHC system:

· A building requiring cooling (e.g., a data center, an airport terminal in summer, or an office with high internal gains) rejects its waste heat into the ambient loop.

· A building requiring heating (e.g., a residential unit, a hotel, or a terminal in winter) extracts heat from the same loop using decentralized heat pumps.

· This allows for thermal synergy. Instead of wasting excess heat from cooling, the system recycles it to satisfy heating demands elsewhere. When perfectly balanced, the only energy input required is for circulating pumps and topping up the temperature via centralized energy centers, which is precisely what CPK is now consulting on.

Scope of the Market Consultations: The Energy Centers

The June 8, 2026, announcement focuses on the "Centra Energetyczne" (Energy Centers). These are not massive, single smokestack plants but decentralized nodes that condition the thermal loop.

The consultations will focus on "doprecyzowanie założeń realizacyjnych Centrów Energetycznych stanowiących zdecentralizowane źródła ciepła i chłodu" (refining the implementation assumptions for the Energy Centers, which are decentralized sources of heat and cold). These centers are the active interfaces of the passive 5th generation loop, ensuring that the temperature remains within the optimal range (e.g., topping up heat in winter or rejecting excess heat to the ground in summer).

Key Technological Focus Areas

The market dialogue is structured to explorespecific hardware and systems integrators. According to the documentation, the consultations will cover:

1. Large-Scale Heat Pumps: The centerpiece of the technology mix. CPK is seeking information on three subtypes:

   · Ground-source (Brine-to-Water): Using vertical borehole heat exchangers (odwierty z wymiennikami ciepła).

   · Air-source: Using ambient air as a thermal source/sink.

   · Water-source (Water-to-Water): Utilizing groundwater, surface water, or wastewater flows.

2. Cooling Technologies: Beyond standard compression chillers, this includes absorption or adsorption chillers that could utilize waste heat from the airport’s cogeneration units or industrial processes to generate cooling.

3. Electric Boilers: For peak load coverage or grid balancing services, providing high-temperature heat when heat pumps alone are insufficient or inefficient.

4. Geothermal Systems: Deep geothermal exploration is mentioned ("systemy geotermalne"), suggesting a long-term view to tap into deep aquifers for stable, baseload renewable thermal energy.

5. Borehole Thermal Energy Storage (BTES): The explicit inclusion of "otworowe wymienniki ciepła" (borehole heat exchangers) implies the use of the ground as a seasonal thermal battery. During summer, excess solar heat or waste heat from cooling can be injected into the ground via BTES; during winter, that stored heat can be extracted. This radically reduces the need for fossil fuel backup.

The Strategic Goal of the Consultations

CPK has outlined a multi-layered purpose for this dialogue. It is not a procurement procedure but a strategic information-gathering exercise. The stated goals are:

· Mapping Market Availability: "rozpoznanie dostępnych na rynku technologii" (recognition of technologies available on the market). Given the rapid evolution of heat pump technology and industrial heat pumps, CPK needs to understand what is commercially available now versus what is in development.

· Efficiency Analysis: "ich efektywności" (their efficiency). The seasonal coefficient of performance (SCOP) of large-scale heat pumps varies dramatically based on source temperature. The consultation will likely produce data on real-world performance in Polish climatic conditions.

· Integration Feasibility: "możliwości integracji" (possibilities of integration). A 5GDHC network is a complex system-of-systems. Integrating a geothermal probe field with air-source heat pumps, electric boilers, and a thermal storage requires sophisticated control logic (often via AI or model predictive control).

· Lifecycle Costing (LCC): "oszacowania kosztów cyklu życia planowanych rozwiązań" (estimating the life cycle costs of the planned solutions). CPK is looking beyond capital expenditure (CAPEX). They are focused on operational expenditure (OPEX), maintenance, and replacement costs over a 25-30 year horizon. This indicates a mature, long-term asset management perspective.

Participants and Process

The consultations are open to a broad spectrum of industry players. The release explicitly invites:

· Contractors and EPC firms (Engineering, Procurement, and Construction).

· Suppliers and manufacturers of heat pumps, chillers, and boilers.

· Design offices (specializing in district energy, piping networks, and hydraulic balancing).

· Integrators of energy systems and automation (crucial for the 5th generation loop’s real-time balancing).

· Entities with specialized knowledge relevant to future procurement.

To participate, interested entities must submit an application via CPK’s procurement platform by June 30, 2026. The consultations proper commence on July 1, 2026. Applicants are required to sign a Non-Disclosure Agreement (NDA – Zał. nr 3), indicating that the technical and commercial details discussed may be sensitive or proprietary.

Crucially, CPK states that "Udział w konsultacjach nie jest warunkiem udziału w przyszłych postępowaniach zakupowych" (Participation in the consultations is not a condition for participation in future procurement proceedings). This is a standard but vital clause to ensure fair competition and encourage open dialogue without fear of being locked out of future tenders.

Why This Matters: The Strategic Context

1. Decarbonization of the Aviation Sector

Airports are hard-to-abate sectors. While Sustainable Aviation Fuels (SAF) and electric aircraft address flight emissions, the airport’s ground operations—terminals, hangars, hotels, and logistics centers—are energy-intensive. A 5th generation network powered by heat pumps and geothermal energy allows CPK to slash Scope 1 and Scope 2 emissions (direct and energy-related indirect emissions) dramatically, potentially achieving net-zero operational carbon long before the national targets.

2. Energy Security and Resilience

By relying on localized, renewable thermal sources (ground, air, water) and rejecting fossil fuels, the airport complex insulates itself from volatile global gas and oil markets. The inclusion of borehole thermal storage provides inherent resilience: a multi-day or multi-week thermal buffer in case of grid outages.

3. Synergy with the National Power Grid

A 5GDHC network with large heat pumps offers immense demand-side flexibility. When the national grid has excess renewable electricity (e.g., windy nights), CPK can run its heat pumps and electric boilers at full capacity, storing heat in the ground or in thermal tanks. Conversely, during grid peak hours, CPK can reduce its electricity consumption. This "virtual battery" capability is highly valuable to Poland’s transmission system operator (PSE), potentially opening revenue streams for CPK through ancillary services.

4. A Blueprint for Polish Urbanism

The CPK project is explicitly intended to catalyze development in the surrounding regions (gminy Baranów, Teresin, etc.). By deploying a world-class 5th generation network here, CPK creates a template for other Polish cities and industrial zones. The press release notes that CPK is sharing knowledge with entities like Łódzka Kolej Aglomeracyjna. Similarly, this energy model could be replicated in other new urban developments.

Addressing Challenges: What the Consultations Must Solve

While the vision is compelling, the 5th generation model presents specific challenges that the Wstępne Konsultacje Rynkowe must address.

· Spatial Requirements for Boreholes: Geothermal probes and BTES require significant land area or deep drilling. Integrating a dense borehole field beneath the airport apron or terminal foundations requires careful structural engineering and thermal modeling to prevent ground freezing or overheating over decades.

· Hydraulic Balancing: With dozens or hundreds of buildings exchanging heat on a single loop, maintaining correct pressure and flow is an order of magnitude more complex than traditional district heating. Advanced sensors and smart valves (IIoT) are essential.

· Low Temperature Design: Existing buildings often have radiators designed for high temperatures (70-90°C). The CPK airport will be built new, so it can have low-temperature underfloor heating or fan coils. However, any retrofitted buildings connected later will require upgrades, a factor CPK must consider for long-term expansion.

· Electrical Infrastructure: Large-scale heat pumps (e.g., 5-20 MW thermal each) are significant electrical loads. This requires close coordination with the local Distribution System Operator (DSO) to ensure substation capacity and grid connection points are available. The consultations will likely probe manufacturers about soft-start capabilities and power quality.

The Broader CPK Energy Vision: What Comes Next?

The consultations on Energy Centers are a critical component, but not the sole element, of CPK’s energy architecture. The website hierarchy reveals other relevant domains:

· Strategiczne Studium Lokalizacyjne (Strategic Location Study): Dictates where energy centers can be placed relative to geology and hydrology.

· BIM w Spółce CPK (Building Information Modeling): The entire energy network will likely be modeled digitally, from the borehole fields to the terminal heat exchangers, enabling predictive maintenance and operational optimization.

· Projekty UE (EU Projects): Given the European Green Deal’s focus on REPowerEU and innovative district heating, CPK is likely positioning to secure substantial EU cohesion and innovation funds for this energy infrastructure. A 5th generation network qualifies for "energy efficiency" and "renewable cooling" categories.

Timeline and Immediate Next Steps

For industry stakeholders, the timeline is specific:

· June 30, 2026: Deadline for submitting the application form (Zał. nr 1) and required declarations to CPK’s procurement platform.

· July 1, 2026: Start of the consultation period.

· Q3-Q4 2026: Following the analysis of market feedback, CPK will likely refine its technical specifications (the Terms of Reference for future tenders).

· 2027-2028: According to the "Plan Postępowań 2026-2028" (Tender Plan), this is when the actual procurement for construction and supply is anticipated.

Conclusion: A New Paradigm for Polish Infrastructure

The launch of market consultations for 5th generation heating and cooling Energy Centers marks a definitive evolution for the Centralny Port Komunikacyjny company. It demonstrates that the "Port Polska" program is not simply an exercise in concrete, rails, and runways, but a sophisticated, integrated infrastructure project for the 21st century.

By committing to a bi-directional thermal network that recycles energy between buildings, utilizes large-scale electric heat pumps, and integrates deep geothermal and borehole storage, CPK is positioning itself at the forefront of Poland’s energy transition. The project aims to demonstrate that a major transportation hub can be a net-positive actor in the local energy system—reducing emissions, enhancing grid stability, and lowering long-term operational costs.

The market is now invited to respond. For energy technology providers, this is a multi-billion złoty opportunity to shape the future of Polish district energy. For Poland, it is a concrete step toward energy sovereignty, decoupling its critical national infrastructure from imported fossil fuels. As the consultations open on July 1, 2026, the international energy industry will be watching closely to see how CPK engineers what could become one of Europe’s most advanced airport-integrated energy systems.

The invitation has been extended. The required technical documentation is published. The deadline of June 30 approaches. The next era of Polish energy infrastructure is now in the hands of the market, engineers, and the visionary team at CPK.
