Holtab

Holtab is a family-owned power technology group founded in 1973 and headquartered in Tingsryd, Sweden. The company is one of the Nordic region’s leading suppliers of power transmission solutions, focusing on energy, infrastructure and industrial customers. Its core offer comprises secondary substations (including compact secondary substations in steel and concrete), primary substations, prefabricated power solutions, technical buildings and low‑voltage switchgear. Holtab applies industrial production techniques in its own factories in Tingsryd, Lidhult and Olofström, where products are assembled, configured and tested before delivery as near “plug‑and‑play” solutions. The group structures its operations into Product, Project and Service divisions, covering standardised CSS products and in‑house HMS low‑voltage switchgear, tailor‑made prefabricated primary and larger subscriber plants and rectifier stations, and installation, maintenance, modernisation and digital services that keep customer installations operating reliably. Holtab’s main geographical market is the Nordic region, particularly Sweden, Denmark and Finland, with an expanding presence in Norway through Holtab Norge AS. It serves segments including energy distribution, smart power grids, solar and wind power, rail transport, e‑mobility, industry and data centres, often delivering complete, turnkey substations and technical buildings designed to meet grid company and safety requirements. Around 330 employees produce roughly 2,500 units per year, generating net sales of about SEK 1,290 million in 2024. Strategic priorities include supporting the energy transition through robust, long‑life (often 40‑year) solutions, SF₆‑free secondary substations, scalable power systems for data centres and heavy‑vehicle charging, and innovations such as the company’s own microgrid in Tingsryd. Holtab emphasises knowledge, service and collaboration, investing in digitalisation, partnerships and long‑term customer relationships to increase reliability, energy efficiency and sustainability across the power system.
