What Municipal Utilities Hameln Weserbergland does

Stadtwerke Hameln Weserbergland GmbH is a municipal multi-utility company headquartered at Hafenstraße 14 in Hameln, Germany, wholly owned by the City of Hameln (sole shareholder since 1939). The entity was formed through the 2021 merger of Stadtwerke Hameln and Stadtwerke Weserbergland, consolidating the regional energy and water operations under a single brand. It serves as the designated Grundversorger (default supplier) for electricity and gas across Hameln and multiple Weserbergland municipalities, holding concession contracts that grant exclusive grid access in its supply area, and supplies approximately 59,048 residents with drinking water. The company reported consolidated revenue of €177.2 million in 2023, a balance sheet total of €295.9 million, and an annual surplus of €7.8 million, supported by 167 employees.

The company operates three core utility verticals (electricity, natural gas, and drinking water) plus an integrated mobility and real estate portfolio. Infrastructure includes a 1,997 km electricity distribution network with 74,344 meters and 391 million kWh annual network load, a 435 km gas network with 18,242 meters and 403 million kWh load, and a 329 km water pipeline network delivering 3.3-3.5 million cubic meters annually sourced from groundwater via four waterworks. Electricity products span fixed-price tariffs with price guarantee through end-2027 (hw regioGARANT.STROM 2027), flexible tiered tariffs (regio.STROM/regioplus.STROM), heat pump-specific (hw regio14.Strom), night storage heating (regioWÄRMESTROM HT/NT), home EV charging, and basic supply (regioBASIS.Strom). Gas products follow a parallel structure. Water is priced volumetrically at €1.82/m³ gross (from January 2026) plus annual meter fixed fees. Renewable generation includes three hydropower plants on the Weser (~12 million kWh/year), 6 MW of wind capacity via TOBI Windenergie GmbH & Co. KG (~12 million kWh/year), 15 own and 600+ private photovoltaic installations (~7.1 million kWh/year), and 11 CHP (blockheizkraftwerk) modules, with the grid area producing 430 million kWh of renewable electricity in 2024.

The business model is subscription-driven across the utility verticals, with monthly billing on an 11-installment annual cadence, complemented by transaction fees from public EV charging (15 stations), parking operations (six facilities totaling 1,850 spaces in Hameln's old town), bike-and-ride subscriptions (116 spaces at Hameln train station), CNG/biomethane fuel sales, and commercial real estate rental in the train station building. Distribution combines direct-to-consumer digital channels (online tariff calculator at portal.stwhw.de), a walk-in customer center, phone and email support, and a dedicated commercial sales manager for high-consumption business customers above 100,000 kWh (electricity) or 300,000 kWh (gas). The company also participates in the Ladenetz roaming network (200+ utilities, 100,000+ charging points across Europe) and co-founded the Klimawerke initiative in May 2022 with 16 other municipal utilities and consulting firm BET to develop a climate-neutrality roadmap.
