What stadtwerk hassfurt does

Stadtwerk Haßfurt GmbH is a municipally owned multi-utility company headquartered in Haßfurt, Lower Franconia, Germany, serving approximately 13,572 residential and commercial customers with electricity, natural gas, water, wastewater, and district heating services. As the licensed Netzbetreiber for its service territory under the EnWG, the company holds a regulated natural monopoly over electricity, gas, and water distribution networks, overseen by the Bayerisches Staatsministerium and the Bundesnetzagentur. The company employs 79 staff and operates alongside the Freizeitzentrum Haßfurt leisure center (Erlebnisbad, Eissportstadion, restaurant).

The company is distinguished by its renewable energy infrastructure portfolio, which exceeds local electricity consumption: 90 million kWh of annual renewable generation from wind, solar PV, biogas, and CHP (111%+ of local demand), supported by a 13.6 MWh battery storage fleet. Stadtwerk Haßfurt operates a 1.25 MW Siemens PEM electrolyzer (operational since 2016) through the Windgas Haßfurt GmbH joint venture with Greenpeace Energy, and a 200 kW hydrogen-fueled CHP unit (H2-BHKW) from 2G Energy AG (operational since 2019), forming a closed renewable storage chain. Additional assets include a 750 kWp PV plant with 2 MWh/2 MW battery (Kombikraftwerk) in the commercial district Ost, and a low-temperature district heating network in Osterfeld II. All residential tariffs supply 100% green electricity under a 6-year PPA with Ottendorf hydropower (since January 2020).

Revenue is generated through multi-utility tariffs (dynamic EEX-linked haStrom Flex, standard electricity, natural gas with optional hydrogen blending, water, and district heating), Wärme Contracting managed services, CNG/LNG fuel sales, and leisure facility admissions. Dynamic tariffs are enabled by 10,000+ smart meters and an Energy Assistant online portal. The company combines regulated grid operations with international recognition as a renewable energy pioneer, featured in the IRENA White Paper "Towards 100% Renewable Energy: Utilities in Transition" and winner of the Bayerischer Energiepreis 2018 and BHKW des Jahres 2019. Its GTM motion is direct-to-consumer and community-led, supplemented by active research partnerships with universities and EU-funded consortia.

Revenue model

1. Electricity Supply: Sale of electricity to residential and commercial customers. Tariffs include standard tariffs, dynamic exchange-price tariffs (haStrom Flex, haStrom Flex Pro), and a 100% green power tariff secured through a 6-year hydro power purchase agreement. Smart meters enable time-of-use pricing.
2. Natural Gas Supply: Sale of natural gas to residential and commercial customers. Includes standard tariffs and a green gas tariff supporting Power-to-Gas expansion. Hydrogen blending of up to 10% (expandable to 20%+) reduces CO2 footprint.
3. Water Supply & Wastewater: Potable water supply and wastewater management for households and businesses in the service area.
4. District Heating (Nahwärme): Supply of low-temperature district heating via a cold district heating network in new housing developments. Customers pay a connection fee and ongoing consumption-based charges.
5. Wärme Contracting: Heat contracting services for buildings, offering turnkey heating solutions without upfront capital cost to the customer.
6. CNG/LNG Fuel Sales: Compressed natural gas (CNG) and LNG sales at the company's fuel station. New station at Augsfelder Str. 24 opened November 2025, also suitable for truck refueling.
7. Leisure & Recreation (Freizeitzentrum): Operation of public leisure facilities including an adventure pool (Erlebnisbad), ice sport stadium (Eissportstadion), and restaurant 'zwischen.drin'. Revenue from admission fees and food & beverage.
8. Power-to-Gas / Windgas Marketing: Green hydrogen production via electrolysis with surplus renewable power. Hydrogen is sold to industrial customers and blended into the gas network. Partnership with Greenpeace Energy (Windgas product) generates revenue through proWindgas customer subscriptions.
9. Grid Operation (Netzbetrieb): Operation of electricity, gas, and water distribution networks in the Haßfurt service area. Grid fees are regulated under German energy law (EnWG) and charged to all users of the network.

Direct peers

• Elektrizitätswerke Schönau (EWS Schönau): German citizen-owned municipal utility that pioneered 100% renewable supply and citizen participation in Schönau in the Black Forest. Direct peer: comparable small-town German municipal utility model built on renewable generation, cooperative ownership, and grassroots engagement — the same operational and cultural template that Stadtwerk Haßfurt now extends into hydrogen and sector coupling.
• Greenpeace Energy: Hamburg-based energy cooperative and joint-venture partner in Windgas Haßfurt GmbH. Directly comparable as a renewable-only German energy supplier with proWindgas/wind-gas products; this is the partner whose customer surcharges fund Stadtwerk Haßfurt's PtG operations, making it the closest revenue-coupled peer.

Broad incumbents

• Stadtwerke München (SWM): Largest German municipal utility (Munich), pursuing its own 'Energiewende München' 100% renewable target with significant wind, hydro, PV, and geothermal investments plus district heating expansion. Comparable in mission and product mix (electricity, gas, district heating, water, mobility) but operates at vastly larger scale, making it a broad incumbent reference point.
• Mainova AG: Frankfurt-based regional multi-utility (electricity, gas, water, district heating, mobility). Comparable as a German municipal utility operating the same core utility product stack (Strom, Erdgas, Wasser, Wärme) with regulated grid operations, though at metropolitan scale rather than rural.
• N-ERGIE Aktiengesellschaft: Regional utility serving Nuremberg and surrounding Middle Franconia with electricity, gas, water, and district heating. Comparable as a Bavarian-adjacent municipal multi-utility with renewable generation, district heating, and EV charging offerings. Broader incumbent than Stadtwerk Haßfurt but operates a similar product set.

Regional players

• Lechwerke AG: Bavarian regional utility serving Augsburg and southern Bavaria with renewable generation (hydro, wind, PV) and grid operations. Comparable regional peer within Bavaria with overlapping renewable generation portfolio and municipal utility origins, though serving a different territory than Haßfurt.

Emerging players

• Lichtblick SE: Hamburg-based supplier pioneering dynamic tariffs, virtual power plants (ZuhauseKraftwerk) aggregating household CHP and battery storage, and 100% renewable supply. Comparable as a German renewable-energy innovation challenger; overlap with Stadtwerk Haßfurt's dynamic haStrom Flex tariff and prosumer orchestration ambitions, though Lichtblick operates at national scale without municipal grid ownership.

Others

• 2G Energy AG: German manufacturer of the hydrogen-fueled CHP module (H2-BHKW) deployed at Stadtwerk Haßfurt. Comparable as a hydrogen CHP / sector-coupling technology supplier rather than a direct utility peer; included as the closest technology counterpart whose hydrogen CHP roadmap aligns with Stadtwerk Haßfurt's sector-coupling vision.
