What ARINET Sp. z o.o. does

ARINET Sp. z o.o. is a privately held Polish engineering design consultancy headquartered in Gliwice with regional field offices in Warsaw (opened September 2025) and Kraków (opened July 2026). Founded in January 2003 by Grzegorz Kowalczyk, an AGH University of Science and Technology graduate in power networks and systems, the firm provides electrical power network design services across the full voltage spectrum — low (nN), medium (SN), high (WN), and extra-high (NN) — for overhead lines, substations, cable networks, telecommunications infrastructure, and smart grid deployments.

The company's core technology portfolio combines conventional engineering design with proprietary, patented innovations. These include the Watucab Ψ modular cable installation system (which achieved a world record 3,106m simultaneous installation of three medium-voltage cables on a TAURON project) and UMKW modular self-supporting gate structures for emergency reconstruction of 110kV, 220kV, and 400kV switchgear substations, both recognized with PTPiREE President's Cup awards. Supporting capabilities include LiDAR-based digital geodesy, 3D structural analysis of lattice and solid-walled power engineering structures, and a catalog of patented trunk lattice pole series for 110kV lines.

ARINET operates a project-based professional services business model with quote-driven, per-project pricing and multi-year contract cadence. Revenue is generated through direct enterprise contracts with major Polish energy distribution operators (TAURON Dystrybucja, PGE Dystrybucja, ENERGA Operator, PSE Operator, PGE GiEK), public procurement tenders, and subcontractor engagements with international engineering offices including Grontmij Polska, Egis Poland, and SWECO Consulting. Secondary segments include municipalities, logistics/real estate developers (Panattoni for Amazon centers), and industrial clients (Grupa Azoty, PCC Rokita). The firm has received non-dilutive R&D funding from Poland's National Centre for Research and Development (NCBiR) for the UMKW development program and maintains an informational marketing presence centered on industry events (ENERGETAB, EPLAN NEXT26, ELEKTROTECHNIKA) and university recruitment at the Silesian University of Technology.

Direct peers

• Eltel Group: Leading European provider of technical services for power and communication networks, listed on Nasdaq Stockholm. Operates across the Nordics, Baltics, Germany, and Poland in HV power network design, construction, and maintenance — directly comparable in service portfolio to ARINET but at significantly larger scale.
• ZUE SA: Polish construction company listed on the WSE specializing in energy and railway infrastructure, including power network construction and design. Competes with ARINET for HV line and substation contracts from Polish utilities and shares the same ENERGA/TAURON/PGE customer base.
• Energoprojekt-Katowice: One of the historically dominant Polish power engineering design offices, headquartered in Katowice. Provides HV power network and substation design services in the same Silesian region and to the same Polish utility customers as ARINET, making it a long-standing direct competitor in HV design.
• Pile Elbud SA: Polish construction company specializing in high voltage (110kV+) power line construction and lattice pole manufacturing. ARINET lists Pile Elbud as a contractor partner, and they work on directly overlapping HV transmission projects in Poland, making them the closest comparable in scale and customer base.
• Trakcja PRKiI: Polish infrastructure group listed on the WSE providing power and railway construction services, including high voltage line design and execution. Overlapping customer base with ARINET across Polish DSO and TSO tenders, though at materially larger scale.

Others

• SWECO: Swedish engineering consulting firm listed on Nasdaq Stockholm with a major Polish operation (including the former Grontmij Polska). ARINET lists SWECO Consulting as a partner/client, indicating they sit on the same multi-discipline project teams as engineering design subcontractors and partners rather than direct competitors.

Regional players

• Mostostal Warszawa: Polish general contractor with EPC capabilities including power infrastructure and industrial construction. Overlaps with ARINET on Polish power infrastructure tenders but operates primarily in Poland at significantly larger combined construction scale.

Broad incumbents

• VINCI Energies: Global energy infrastructure services business of VINCI, providing power network design, construction, and maintenance across dozens of countries. Their Polish operations including power infrastructure compete with ARINET but as part of a vast multi-country portfolio.
• Polimex Mostostal: Major Polish EPC general contractor listed on the WSE, with significant power infrastructure and industrial construction capabilities. Operates at a much larger scale than ARINET but competes for the same DSO/TSO and industrial client power-line and substation projects in Poland.
• SPIE SA: European multi-technical services company listed on Euronext Paris, providing electrical, mechanical, and communications infrastructure services across Europe. Their power network design and construction capabilities overlap with ARINET's offering but as part of a much broader multi-technical portfolio.
