What Stadtwerke Südholstein does

Stadtwerke Südholstein GmbH is a German municipal utility company (Stadtwerke) headquartered in Pinneberg, Schleswig-Holstein, with roots going back to 1856. It supplies electricity (100% renewable ÖkoStrom), natural gas (ErdGas), drinking water, district heating (Fernwärme), e-mobility charging, and fiber broadband to residential and commercial customers across the Südholstein region, with primary concession network areas in Pinneberg and Tornesch. The company is registered as a GmbH with the Amtsgericht Pinneberg (HRB 5172) and is supervised by the Bundesnetzagentur, consistent with its regulated municipal-utility status.

The operating stack combines energy supply with local infrastructure: drinking water is drawn from twelve own wells in Pinneberg plus a deep well in Wedel for Tornesch, processed without chemical treatment; district heating is generated primarily from waste-incineration byproducts and supplemented by a gas-fired combined heat and power plant (BHKW) in Tornesch, achieving a low primary energy factor compliant with the Gebäudeenergiegesetz. ÖkoStrom is offered in fixed-price variants (ÖkoStrom fix, ÖkoStrom fix 2027), a regional sourcing option, and a heat-pump-specific tariff eligible for reduced network charges under §14a EnWG, with all variants ÖkoStrom D 100 certified and tracked via the Umweltbundesamt Herkunftsnachweisregister. E-mobility services include a charging card and wallbox products integrated with the ladenetz.de public charging network, and fiber internet is delivered through the affiliated pinnau.com brand.

Commercially, Stadtwerke Südholstein operates a direct-to-consumer go-to-market model via two physical customer centers (Pinneberg, Tornesch), a service hotline, an online customer portal, and a website-based product calculator. Revenue is generated through consumption-based prices plus fixed base fees structured by meter size (water) and capacity/connection (district heating), with annual contract adjustments tied to market indexation. The corporate group includes grid operator Netze Südholstein, Abwasserbetrieb Pinneberg (wastewater), Bäder Pinneberg (swimming facilities), pinnau.com (fiber), and Kommunalwirtschaft Pinneberg GmbH. Managing Director Thomas Behler leads the company under Chairman of the Supervisory Board Carl-Eric Pudor, in a governance structure typical of German municipal utilities.

Revenue model

1. Energy Supply (Electricity & Gas): Core revenue stream from supplying electricity (ÖkoStrom) and natural gas (ErdGas) to residential and commercial customers in the Südholstein region and broader Schleswig-Holstein/Hamburg areas. Revenue is generated through a combination of consumption-based (usage/kWh) charges and fixed base fees (Grundpreis/Grundgebühr). Products include fixed-rate options with price guarantees through 2027.
2. Water Supply: Drinking water supply to residential and commercial customers in Pinneberg and Tornesch. Revenue is generated through consumption-based water prices (per m³) plus fixed meter-based fees (Grundgebühr) structured by meter size (Qn rating). Water is sourced from regional wells with no chemical treatment.
3. District Heating (Fernwärme): Supply of heating energy via a local district heating network in Pinneberg and Tornesch. Revenue is generated through a combination of a consumption-based working price (Arbeitspreis), a capacity-based base price (Grundpreis), a meter price (Messpreis), and a billing price (Verrechnungspreis). The heating price is linked to average heat market development to smooth price fluctuations.
4. E-Mobility Charging Services: EV charging infrastructure providing charging card (Ladekarte) and wallbox services, with access to public charging points through the ladenetz.de network.
5. Swimming Pool Operations (Bäder Pinneberg): Operation of swimming pool facilities in Pinneberg as part of the company's community service role, managed via a separate entity (Bäder Pinneberg).
