The energy dependence of modern civilization is unquestionable.
The division’s goal is to provide diverse and reliable solutions for both residential and business needs.
In line with diversification requirements supporting energy security, in addition to traditional gas and district heating pipeline construction and reconstruction related to energy networks, activities have, over recent decades, also extended into the power plant sector. As a result, the company has become a significant player in the energy industry.
Several key projects have strengthened the company’s market position: in Kecskemét, the complete design and construction of a biomass heating plant was realized, while, among others, at the Vértes, Ajka, Pécs, Budapest, and Debrecen power plants, mechanical and technological upgrades were carried out as part of modernization efforts.
The enforcement of sustainability aspects is also supported by the application of so-called no-dig technologies.
Uniquely in Hungary, the company possesses the know-how for tunnel boring, or so-called microtunneling technology, along with its own equipment fleet and a team of experts with several decades of experience.
Additionally, the company holds a leading market position in pipe bursting technology.

Construction of district heating supply for the BUDAPART residential district
Building a pre-insulated, PE-jacketed, steel service pipe, signal-system-equipped, directly buried district heating pipeline system:
- DN 800 (812.0x8.8) / 1000: 307 metres of trunk pipeline
- DN 150 (168.3 x4.0) / 280: 64 metres of connection pipeline
- DN 100 (114.3x3.6) / 225: 47 metres of connection pipeline
Gas distribution pipeline reconstruction work
Budapest, District XVIII, Liszt Ferenc Airport - Vecsés gas transfer station; between Vecsés gas transfer station and M4 motorway section
- 1645 meters of DN 315 PE 100/G SDR 11 high-medium pressure distribution pipeline via open trench
Construction of main steam pipeline at Bakonyi Power Plant Zrt.
The owner wanted to operate 2 power plant units in a way that the Boiler 2 ran with Turbine II, and the Boiler 1 with Turbine III in unit mode, using biomass and SRF (Solid Recovered Fuel) as fuel.
The project entailed constructing the water and steam side connection between Boiler 1 and Steam Turbine III.
The main steam pipeline built: Material quality X20CrMoV11-1 (1.4922), cross-section 323.9 x 36 mm, operating pressure 91.1 bar, operating temperature 540°C.
Stack demolition at Vértes Power Plant
The stack of the Vértes Power Plant was built between 1959 and 1961. The structure had been out of operation for more than a decade following minor damage from a moderate earthquake.
As part of the 120-meter-high chimney’s renovation, the top 20 meters were dismantled, and the remaining 100-meter-high structure was refurbished.
During construction, industrial mountaineering techniques were used to build an elevator at 100 meter height, scaffolding was erected, and the risk of the stack's internal collapse was eliminated.
Design and construction of biomass heating plant in Kecskemét
Within the framework of an investment worth nearly EUR 17 million, a 20 + 5 MW biomass-based renewable energy plant was designed and built. The project was implemented for Termostar Kft., the district heating provider, in the southern industrial area of Kecskemét.
The heating plant is connected to the city’s existing district heating system via a new, energy-efficient trunk pipeline, forming a unified energy system.
Fuel required for economical operation is provided by biomass from selectively collected green waste, woody plants, sunflower husks, and by-products from the wood industry not suitable for other uses.
District heating pipeline construction in Kecskemét
Laying 4300 meters of DN350/500 pre-insulated district heating pipeline (partially under the railway).
