OMEXOM

What OMEXOM does

OMEXOM GA Energo s.r.o. is a Plzeň-based electrical infrastructure services company founded in 1993 by Zdeněk Žídek and colleagues, now operating as a wholly-owned subsidiary of VINCI Energies within the OMEXOM brand network (250 business units in 40 countries). The company delivers construction, reconstruction and modernization of high-, medium- and low-voltage power lines, substations and transformer stations across the full voltage spectrum (VVN, VN, NN), alongside transformer repair, oil testing and eco-friendly disposal for the 50–1600 kVA / 6–35 kV range. It also operates a Smart City solutions line anchored by a physical Smart City Polygon demonstration facility, supported by project documentation, construction services and an explicit innovation function. Technology differentiation rests on proprietary PRIMTECH 3D design software, the Smart City Polygon proof-of-concept asset, and the recently acquired Safety Culture Ladder Level 4 certification (the only company in the Czech Republic to hold it).

Revenue is generated primarily through B2B professional services on a project basis, with supplementary hardware revenue from transformer oil sales and disposal. The go-to-market is direct enterprise sales to electricity transmission and distribution operators — ČEZ Distribuční služby, E.ON Servisní, EG.D, ČEPS and PREdistribuce domestically, plus TenneT TSO internationally — supplemented by partnerships with sister OMEXOM entities and contractors such as Omexom Netherlands and BAM Infra on Western European projects. Operations span the Czech Republic (Plzeň headquarters plus branches in Teplice, Brno, Louny, Česká Lípa, Jirkov, Nekmíř and Prague) and internationally in the Netherlands, Belgium, Austria and Germany, with the VINCI Energies Academy Czech/Slovakia branch (opened April 2025 in Brno) formalizing workforce development across 1,750+ regional employees. Customer mix is concentrated in regulated utilities and TSOs, and a single 2025 contract with TenneT for the Zuid Groningen Ter Apelkanaal 380/110 kV substation exceeds 200 million CZK in OMEXOM GA Energo's assembly share alone.
