Herzo Werke GmbH

What Herzo Werke GmbH does

Herzo Werke GmbH is a municipal utility (Stadtwerk) headquartered at Schießhausstraße 9, 91074 Herzogenaurach, Bavaria, Germany, providing electricity, natural gas, drinking water, and district heating services to households and businesses within the Herzogenaurach concession area, with ancillary e-mobility offerings including public EV charging, car sharing, home wallbox solutions, and e-bikes. The company operates as a regulated monopoly network operator and as the grundzuständiger Messstellenbetreiber (gMSB) under the Messstellenbetriebsgesetz (MsbG), responsible for installing, operating, and maintaining approximately 11,976 modern metering devices and 2,031 intelligent measurement systems across its network area. Its technology platform includes a digital Netzportal (netzportal.herzowerke.de) for self-service registration of distributed energy resources — PV systems, heat pumps, battery storage, and EV chargers — and grid-friendly control systems (netzdienliche Steuerung) per §14a EnWG for managing controllable consumer facilities.

The company generates revenue through five regulated and semi-regulated streams: regulated network charges (Netzentgelte) for electricity and gas distribution, retail supply of electricity and natural gas (including dynamic tariffs such as HERZOstrom puls and Powertarife), drinking water supply, district heating, and metering operations (Messstellenbetrieb), plus usage-based revenue from e-mobility charging. The business model is fundamentally subscription- and volume-based with regulated rate-of-return economics, and go-to-market is direct to consumer via a physical service office at headquarters, the Netzportal online channel, and direct billing via metering infrastructure. The company is managed by Geschäftsführer Dietmar Klenk with Dr. German Hacker as Chairman of the Supervisory Board, reflecting a standard German GmbH governance structure typical of municipal utilities. There is no public revenue, funding, or headcount data disclosed; the firm is privately held under municipal ownership of the city of Herzogenaurach.
