ElectroAir in Poland: Building the next generation of airport power at Wrocław and Rzeszów-Jasionka
Poland is where our ground power portfolio becomes full-scale infrastructure. From under-apron PIT systems and bespoke distribution pillars to high-capacity 400 Hz converters, ElectroAir solutions are shaping how airports deliver reliable, clean, and efficient energy to aircraft and MRO operations.
Wrocław Airport: Powering the Largest Modernization in Its History
The modernization of Wrocław Airport marks one of the most ambitious infrastructure programs ever undertaken in Poland’s aviation sector. This multi-phase project, officially described as the airport’s largest investment in its history, required a temporary suspension of flight operations to enable a full reconstruction of apron areas, taxiways, and critical technical systems. At the core of this transformation lies a next-generation ground power infrastructure engineered and delivered by ElectroAir.
ElectroAir has been a long-standing technology partner to Wrocław Airport. Our EAC-90 solid-state frequency converters have supported daily operations for years, ensuring stable 400 Hz supply across the terminal area. In this new upgrade phase, we are supplying a fully integrated electrical and service backbone, a system in which energy generation, distribution, and point-of-use delivery form one cohesive, intelligent network, operating mostly beneath the surface yet essential to every aircraft turnaround.
The scope of supply includes 28 underground hatch PIT systems providing access to 400 Hz power and utility connections, 14 EAC solid-state frequency converters for ultra-stable power output, a series of custom-engineered distribution pillars designed specifically for the geometry and operational demands of the Wrocław apron, and multiple kilometres of sub-surface cabling linking all service nodes together. Each element has been designed for maximum reliability, efficiency, and environmental resilience, ensuring uninterrupted operation in Poland’s challenging seasonal conditions.
A defining feature of this modernization is the digital integration layer. ElectroAir’s systems at Wrocław are equipped with RFID-based access control, ensuring that every activation of power or service equipment is authorized, logged, and fully traceable. This enhances operational security, supports precise billing, and prevents unauthorized equipment use, a key requirement for modern high-traffic aprons.
Beyond access control, each PIT system and converter is designed to transfer operational and metering data directly into the airport’s management system (AMS). This includes usage statistics, equipment status, power consumption, event logs, and maintenance indicators, all streamed in real time. The result is a unified data environment that enables predictive maintenance, eliminates manual reporting, and gives airport operations full visibility of their energy ecosystem.
What makes this project exceptional is not just its scale, but its orchestration: every subsystem, electrical, digital, safety, and environmental, is integrated into a single coherent architecture. The combination of clean underground power delivery, intelligent monitoring, reduced noise and emissions, and faster, data-driven turnarounds ensures that Wrocław Airport now operates with the efficiency and precision of a next-generation European hub. ElectroAir’s dual expertise in engineering and manufacturing allowed the airport to adopt an infrastructure model built not only for today’s requirements, but ready for decades of future growth.
Scope of delivery
• 28x underground hatch PIT systems (400 Hz power, utilities).
• 14x EAC solid-state frequency converters for 400 Hz.
• Custom distribution pillars for optimized apron layout.
• Sub-surface cabling linking all systems into a single network.
Impact and benefits
• Clean, organized apron with minimal cable clutter.
• Faster aircraft servicing and reduced APU dependency.
• Significant reduction in energy losses, noise, and emissions.
• Long-term reliability and scalability for future airport expansion.
• Reinforces ElectroAir’s leadership in integrated airport energy systems in Central Europe.
Rzeszów-Jasionka (LOT AMS): 13 PIT Systems (4 types) Delivered in 10 Weeks
At the LOT AMS maintenance base in Rzeszów-Jasionka, ElectroAir achieved one of its most ambitious project deliveries in recent years, a full under-floor services infrastructure completed in record time. Within just ten weeks, our team designed, produced, delivered, and commissioned four types of PIT systems (in total 13 pcs), ensuring the new LOT AMS hangar complex could operate at full efficiency from day one.
The scope included nine Electric PIT systems (in two configurations for different bay requirements), two PCA PIT systems for pre-conditioned air supply, and two fuel-tank ventilation PIT systems for safe fuel maintenance operations. This combination provides a complete ecosystem beneath the hangar floor, electrical power, conditioned air, and fuel safety interfaces, all accessible through flush-mounted hatches that keep the workspace clear and hazard-free. Each PIT is factory-assembled, pressure-tested, and supplied as a pre-integrated module to minimize on-site installation time and ensure total reliability.
The new LOT AMS facility itself is one of Poland’s most advanced MRO hubs, built to service wide-body aircraft and long-haul fleets with state-of-the-art maintenance workflows. ElectroAir’s rapid deployment of these critical systems helped LOT AMS meet its commissioning deadlines and launch operations ahead of schedule, a testament to our ability to combine European manufacturing, engineering precision, and agile project management.
Behind the speed was planning: every PIT system left our factory as a fully tested, plug-and-play assembly with dedicated electrical, pneumatic, and monitoring interfaces. This approach cut civil and electrical installation work on-site to a minimum, reduced project risk, and ensured consistent quality across all bays. For LOT AMS, it meant one clear advantage, being able to connect the aircraft, not the cables.
Scope at LOT AMS
• 9x Electric PIT systems (two configurations).
• 2x PCA PIT systems for pre-conditioned air at the apron.
• 2x Fuel-tank ventilation PIT systems ensuring safety during maintenance.
• Full engineering, production, testing, delivery, and commissioning cycle within 10 weeks.
Impact and significance
• Demonstrates ElectroAir’s ability to deliver turnkey infrastructure under extreme time constraints.
• Provides a clean, efficient, and APU-free work environment inside the hangar.
• Enhances safety and operational readiness for Poland’s fastest-growing MRO hub.
• Strengthens our long-term presence and trust within the Polish aviation sector.
