What WEA Wärme- Und Energieanlagenbau GmbH does

WEA Wärme- und Energieanlagenbau GmbH (trading as WEA Erfurt) is a German private limited company (GmbH) headquartered in Erfurt, Thuringia, that delivers technical infrastructure services for energy, water, heat, and telecommunications networks. The company operates approximately 200 employees across four sites in the Erfurt region and is a subsidiary of Freitag Gruppe, a diversified European group of 28 companies operating at 10 locations with roughly 3,000 employees. WEA is led by two managing directors, Dipl.-Kaufm. Joachim Freitag and B. Eng. Tobias Möller.

The company's offering is organized into nine interconnected service areas: metering, electrical installation, transformer stations, switchgear construction, cable networks (up to 110 kV), pipeline construction (DVGW and AGFW certified), renewable energy systems, lighting installations, and complex network construction. Technical differentiators include DVGW-certified gas and water pipeline construction (GW301, G468-1), high-voltage cable work up to 110 kV including live low-voltage operations, type-tested low-voltage switchgear approved by IPH Berlin, and smart metering infrastructure deployment. The company holds DIN EN ISO 9001:2015 certification issued by DEKRA. It also operates a customer-facing online meter reading portal for gas and electricity.

WEA serves three primary vertical segments: energy utilities, municipalities and the public sector, and industrial customers. Revenue is generated through project-based infrastructure construction (one-time contracts), recurring maintenance and operations services, metering services (installation, reading, data management), and rental transformer station services. The business is B2B with regional sales coverage in Thuringia, supplemented by the broader European reach of its parent group. No revenue is publicly disclosed.
