What Stadtwerke Dreieich does

Stadtwerke Dreieich GmbH is a municipal utility company headquartered in Dreieich, Germany, founded in 1906 and operating under the parent holding Stadt-Holding Dreieich GmbH. It supplies approximately 46,000 residents across all five Dreieich districts with electricity, natural gas, drinking water, and district heating (Dreieichwärme), and operates additional public services including two swimming pools (Hallenbad and Parkschwimmbad) and city bus transport (Verkehrsbetriebe). The company runs 8 deep wells producing roughly 3 million cubic meters of drinking water per year, a 178 km water pipeline network, combined heat and power (BHKW) district heating assets, and public EV charging stations; it is the regional grid operator under the joint venture Stadtwerke-Netzdienste Dreieich und Neu-Isenburg GmbH established in January 2024.

The business is built around regulated network operations and customer-facing energy supply across residential, commercial, and municipal segments. Revenue streams include Grundversorgung (default supply) and fixed-price electricity and gas contracts, the ÖkoStrompur green tariff (TÜV Nord certified), volumetric water charges, and an expanding portfolio of decarbonization products: Solarpur photovoltaic rent-to-own, Thermopur heating rental (since 2024 exclusively 65% renewable solutions), Klimapur split air conditioning, and EV charging. Distribution combines a physical customer center, online customer portal, the Dreieich+ mobile app with Vorteilswelt loyalty program, dedicated account managers for business customers above 20,000 kWh electricity or 150,000 kWh gas consumption, and 18 regional craft partners for installation work.

In FY2024, the company reported €74.9 million in revenue and an €8.7 million annual surplus, up from €8.2 million in 2023 and €6.9 million in 2022, with approximately €11 million invested in infrastructure renewal and expansion. Profitable utility operations cross-subsidize structurally deficit-generating public services (Bäder deficit €1.9M, Verkehrsbetriebe deficit €487,000 in 2023). The company published its first voluntary sustainability report alongside FY2024 results and operates AI-assisted PV potential analysis via a partnership with Kenergy Solutions.
