Northern German energy utility managing 1,100+ municipal networks and renewable infrastructure
HanseWerk-Gruppe operates electricity, gas, and heating networks across ~1,100 municipalities in northern Germany, operating roughly 2,300 staff. The tech stack is enterprise-heavy (SAP, Power BI, Microsoft Fabric, SCADA, GIS) with operational technology standardization and network digitalization as active focus areas—a pattern typical of utilities modernizing decades-old grid infrastructure. Active hiring skews toward mid-level engineering roles, suggesting scaled deployment of network modernization rather than exploratory R&D.
HanseWerk-Gruppe is one of northern Germany's largest energy service providers, operating electricity, gas, and heating distribution networks across roughly 1,100 municipalities. The company also runs biomass-based combined heat and power plants and manages EV charging stations. Owned by E.ON, the group plans to invest approximately €1.25 billion over three years in network expansion and innovation. Core operations center on network infrastructure maintenance, renewable energy integration (wind, solar), and emissions reduction through grid modernization and efficient heating solutions.
Primary systems include SAP, Microsoft 365, Power BI, and Microsoft Fabric for business operations. Network management relies on SCADA and GIS. Development tooling spans Python, SQL, Jira, Confluence, Docker, and Linux.
Active projects include OT standardization for E.ON, redesigning customer service IT systems, integrating renewable energy injection plants, digitizing lab and low-voltage processes, and building internal network forecasting and planning tools.
