It provides vertically integrated electricity, natural gas, drinking water, and district heating supply to approximately 11,385 residents across a 20.0 km² supplied area within a 107.1 km² geographic region. Core infrastructure includes ~11.3 km medium-voltage cable, ~223.8 km low-voltage cable, ~92.8 km gas pipeline, and ~140 km water pipeline, supported by a 37 MVA installed transformer capacity. The company also operates the RothenburgBad bathing complex (indoor pool, outdoor forest pool, sauna & wellness, restaurant, bowling) and an in-house construction company for real estate development (e.g., Wohnbau Viva I project, 15 residential units). Technology infrastructure includes smart metering rollout under MsbG requirements (~6,470 modern and ~1,279 intelligent metering points), a GIS-based network documentation system, and a 166.53 kWp rooftop PV system at RothenburgBad commissioned June 2026.

The company generates revenue through recurring subscription-based tariffs for energy and water supply (RothenburgStrom, RothenburgGas, Trinkwasser, RothenburgWärme sub-brands including eco-variants RothenburgStrom Öko dynamik and RothenburgGas bio 65), usage-based grid fees for electricity and gas network access (regulated natural monopoly), unit-priced bath and wellness admissions with loyalty discounts via RothenburgEnergie Card, one-time real estate revenues, and nationwide energy trading on spot and forward markets. Customer segments span private households, commercial businesses, industrial customers, municipalities, and other energy suppliers utilizing the distribution network. Group sales volumes reached 842.2M kWh electricity and 811.3M kWh gas in FY2025, dwarfing local network volumes (54.3M kWh electricity, 110.8M kWh gas) due to nationwide trading activity. FY2025 total sales revenue was ~144M EUR including energy taxes.

Distribution combines a physical customer center at Steinweg 25, the 24/7 RothenburgEnergie Portal, an online tariff calculator, and TSM-certified regulated grid infrastructure (VDE/DVGW certification for electricity, gas, and water networks). Marketing leverages the company website, local media, RothenburgBad events, and an easy-language accessibility version. Certifications include TOP-Lokalversorger 2026 across all four product categories, TÜV Austria, and E-Mobilität Siegel. Leadership consists of Managing Directors Dieter Brünner (Sprecher) and Erich Weber, with Mayor Christoph Rösch chairing the supervisory board as city representative. The company paid ~560 TEUR in concession fees (Konzessionsabgaben) to Stadt Rothenburg in FY2025.

• Mainova AG: Frankfurt-based municipal multi-utility providing electricity, gas, water and district heating — a comparable German Stadtwerk model at larger scale, serving as a benchmark for regulated multi-utility economics.
• SWK Stadtwerke Krefeld AG: Mid-sized German municipal utility with electricity, gas, water, district heating and public transport/baths — highly comparable in the bundling of regulated utility services with public baths and real estate.

Broad incumbents
