What stadtwerke hildesheim does

Stadtwerke Hildesheim (SWHI) is a 100% municipally-owned multi-utility group headquartered in Hildesheim, Lower Saxony, Germany, operating across the regulated and competitive segments of the energy and municipal services value chain. Through its core subsidiary EVI Energieversorgung Hildesheim, the group supplies electricity, natural gas, drinking water and district heating to more than 100,000 residents and commercial customers in Hildesheim and the surrounding region, over a network footprint exceeding 2,000 km. Adjacent subsidiaries SVHI (urban bus transit under the ROSA tariff association, ~9.1 million km/year) and VUB (Wasserparadies Hildesheim leisure facility, ~400,000 visitors/year) extend the platform into mobility and recreation. The group also holds minority stakes in RVHI Regionalverkehr Hildesheim, Harzwasserwerke, and Stadtwerke Sangerhausen.

The underlying technology stack combines regulated network operations (electricity and gas distribution under Bundesnetzagentur oversight) with a growing digital layer that includes the Klima-Cockpit Hildesheim digital energy twin, the HildesHaus home energy management system (HEMS) app, the hiApp city information app, the Meine EVI online customer portal (powered by SIV AG), and the SWHI Big Picture interactive dashboard. EV charging infrastructure with 24/7 hotline support and E-Mobilit t charging cards layer e-mobility into the offering, while EVI SolarAnlage and the Dynamischer Stromtarif extend the portfolio into distributed generation and dynamic pricing. The GIPS CMS from Hehner Reus Systems underpins the public web properties.

Commercially, SWHI operates a hybrid model: regulated, usage-based revenue from grid fees (Bundesnetzagentur / Regulierungskammer Niedersachsen), subscription/recurring retail revenue from electricity, gas, heat, water and transit tariffs, transactional revenue from solar installations and leisure admissions, and ancillary revenue from EV charging and loyalty programs (HI+ Vorteilswelt, EVI Heimvorteil). The group reaches customers through both self-serve digital channels (online portals, app stores, hiplus.evi-hildesheim.de) and physical Kundencenter locations, supported by 24-hour outage hotlines and 70,000+ customer interactions per year. As a GmbH wholly owned by the City of Hildesheim, strategic oversight is exercised by an Aufsichtsrat chaired by Oberbürgermeister Dr. Ingo Meyer, with operational leadership split between Wolfgang Birkenbusch (Technical Managing Director) and Mustafa Sancar (Commercial Managing Director and Spokesperson of the Management Board since July 2026).
