What TZ Stromag does

TZ Stromag is a Swiss electrical engineering services company (Elektrotechnik) founded in 1993 and headquartered in Brig-Glis in the Upper Valais (Oberwallis) canton. It is the largest electrical contractor in the region, operating five directly-owned branches across Visp, Fiesch, Raron, Zermatt, and Riederalp, plus additional locations managed through wholly-owned sister entities Elektrohüs, Elektro Saas, and Gasser Elektro ICT, totaling approximately 125 employees (32 apprentices). The company serves residential, commercial/industrial, and public-infrastructure customers with a full portfolio that begins at the energy consumption point and covers electrical installations, service and maintenance, security systems, in-house switchgear manufacturing (Schaltanlagenbau), automation, telematics, photovoltaic systems, and ICT services.

The core technical capability rests on its own switchgear assembly operation, which supports custom build-to-spec products for local industrial customers and provides a degree of vertical integration typically absent from pure-installation contractors. The product portfolio is horizontally segmented across installation, service/maintenance, security, switchgear, automation, telematics, PV, and ICT — a '360-degree' services proposition supported by a dedicated solar calculator tooling (sunin.ch). Notably, TZ Stromag has delivered marquee cantonal infrastructure projects including the NEAT (New Alpine Rail Link) and the Matterhorn Terminal for Matterhorn Gotthard Bahn, demonstrating bilingual execution capability across German- and French-speaking parts of Valais.

TZ Stromag operates as a wholly-owned subsidiary of Burkhalter Holding AG (via Burkhalter Gruppe) and monetizes through project-based professional services revenue: electrical installations, recurring service and maintenance contracts, and PV deployment. Its go-to-market is sales-led and locally direct, anchored by physical branch presence across Upper Valais, with referral channels from the broader Burkhalter Gruppe network. The company holds no public revenue disclosure, funding rounds, or M&A activity in the data; growth signals come from active hiring, the PV vertical, and integration within the Burkhalter cluster of sister companies (HVAC, sanitation, engineering) for bundled multi-trade bids.
