What Stadtwerke Rastatt does

Stadtwerke Rastatt GmbH is a municipal utility (Stadtwerke) wholly owned by the city of Rastatt in Baden-Württemberg, Germany, delivering five core utility services — electricity, natural/bio gas, drinking water, district heating (Fernwärme), and e-mobility charging — to residential, commercial, industrial, and municipal customers in Rastatt and surrounding districts including Kuppenheim and Förch. The company operates the regulated electricity, gas, water, and heating distribution networks in its concession area, supplemented by owned generation assets (hydropower, photovoltaic installations) and certified 100% renewable Ökostrom products sourced from European wind, solar, and hydro providers. Technical capabilities include two groundwater-fed waterworks (Ottersdorf and Rauental) with activated-carbon PFAS filtration (Ottersdorf modernized in July 2024 with six activated carbon filters), an expanding district heating pipeline network mapped via an interactive online tool, and a public EV charging network offering AC charging up to 22 kW and DC fast charging up to 150 kW through partnerships with TotalEnergies and GoingElectric.

The business model combines regulated and competitive revenue streams: subscription-based supply tariffs (electricity, gas, water, district heating) with regulated volumetric pricing (water at EUR 3.22 gross/m³ from January 2026), usage-based fees for EV charging (EUR 0.46/kWh for AC) and biogas-blending surcharges (0.5–5 ct/kWh), and professional-services revenue from photovoltaic system installations delivered through Stadtwerke Rastatt Service GmbH — a joint venture with Stadtwerke Karlsruhe. The company reaches customers through a walk-in customer center at Markgrafenstraße 7 in Rastatt, a 24/7 online customer portal, phone sales, community sponsorship (e.g., Stadtwerke Rastatt Sommer Cup), and a referral program (Kunden werben Kunden). Supporting infrastructure includes the Rastatt E-Mobil app for charging authorization, smart-meter rollout mandated through 2032, and direct federal subsidy facilitation for district heating connections (up to 70%) and multi-family EV charging (up to EUR 2,000 per parking space). Ownership is municipal; the company is unlisted and not engaged in external fundraising.

Product overview

Stadtwerke Rastatt is a municipal utility providing a diversified portfolio of regulated and competitive energy services to residential and commercial customers in Rastatt, Germany. The core portfolio is organized into five main supply categories — electricity (Ökostrom), gas (Bio-/Erdgas), district heating (Fernwärme), drinking water (Trinkwasser), and e-mobility (Ladeinfrastruktur) — each with associated service modules. The electricity offering centers on certified 100% renewable Ökostromtarife, supplemented by dynamic pricing (RASTATTStrom Flex) and a default Grundversorgung tariff, while a complete PV and balcony-powerplant offering is delivered through the Stadtwerke Rastatt Service GmbH subsidiary. The gas portfolio includes standard and bio-blended Erdgastarife with multiple biogas mixing ratios, plus CNG/bio-CNG refueling stations. District heating (Fernwärme) is delivered via an expanding pipeline network with an interactive map for demand-driven expansion. Water supply is sourced from two groundwater waterworks with PFAS remediation via activated carbon filtration. E-mobility encompasses public AC/DC charging stations, commercial charging solutions, multi-family charging management, and private wallbox registration — all powered by 100% eco-electricity. Supporting these are digital service layers including a customer portal, smart meter rollout, online meter reading, and grid infrastructure services.

Direct peers

• Stadtwerke Karlsruhe: Larger municipal multi-utility in neighboring Karlsruhe; joint venture partner in Stadtwerke Rastatt Service GmbH for PV installations. Directly comparable as a Baden-Württemberg Stadtwerke with electricity, gas, water, district heating, and EV charging portfolios serving a mid-sized German city.
• Stadtwerke Heidelberg: Municipal multi-utility in Heidelberg providing electricity, gas, water, district heating, and e-mobility to a mid-sized Baden-Württemberg city. Direct peer in terms of municipal ownership, product portfolio, and Energiewende positioning.
• Stadtwerke Pforzheim: Municipal multi-utility in Pforzheim, Baden-Württemberg, offering electricity, gas, water, district heating, and EV charging. Direct peer in scale, product mix, and regional energy-transition strategy.
• Stadtwerke Gaggenau: Neighboring municipal utility in Gaggenau that supplied Stadtwerke Rastatt with emergency drinking water during the 2013–2018 PFAS crisis. A near-twin Stadtwerke in the same German region with comparable multi-utility scope at similar scale.
• badenova AG & Co. KG: Regional energy and water utility based in Freiburg serving Baden with electricity, gas, heat, water, and e-mobility services. Closely comparable as a Baden-region municipal/regional utility with a renewable-energy focus and similar product breadth.

Broad incumbents

• E.ON SE: Europe's largest energy retail and distribution group with broad electricity, gas, heat, and e-mobility offerings. Competes for the same residential and commercial customers as Stadtwerke Rastatt but at national scale with much greater digital infrastructure.
• RheinEnergie AG: Cologne-based municipal multi-utility supplying electricity, gas, water, heat, and EV charging across the Rhineland. Comparable municipal ownership structure and multi-utility model at significantly larger scale.
• EnBW Energie Baden-Württemberg AG: Dominant regional energy incumbent across Baden-Württemberg, with generation, distribution, and retail activities. Overlaps with Stadtwerke Rastatt across electricity distribution, EV charging, and renewable generation, but at vastly larger scale and broader geographic scope.
• MVV Energie AG: Listed municipal energy company in Mannheim providing electricity, gas, heat, water, and e-mobility across the Rhine-Neckar region. Comparable product breadth, but larger scale, partially listed, and broader geographic reach.

Emerging players

• Naturstrom AG: German renewable-energy supplier offering Ökostrom, biogas, heat, and EV charging with a sustainability focus similar to Stadtwerke Rastatt's positioning. Smaller and more specialized than municipal utilities, but competes for the same sustainability-oriented customers in Baden and beyond.
