Stadtwerke Koblenz

What Stadtwerke Koblenz does

Stadtwerke Koblenz GmbH is a 100% municipally-owned utility (Stadtwerke) of the City of Koblenz, Germany, providing a diversified portfolio of public infrastructure and essential services. The group operates the Rheinhafen Koblenz — the last high/low-water independent inland port on the Rhine before the Rhine highlands — handling roughly 900,000 tonnes of cargo and ~1,100 ships annually via a trimodal water-rail-road platform with two container cranes, a loading bridge, rotary crane and stackers, plus adjacent warehouse and commercial land rentals. Through wholly-owned subsidiaries it delivers public transport (Koblenzer Verkehrsbetriebe / koveb with ~100 modern buses), water supply (Vereinigte Wasserwerke Mittelrhein serving ~150,000 residents across 717 km of pipeline and 40 reservoirs; 60%-held Wasserwerk Koblenz/Weißenthurm producing 6.225M m³/yr), renewable generation (12-turbine Windpark Westerwald at ~40 GWh/yr and the KO-Solar JV with evm and the City of Koblenz), the Moselbad aquatic center opened August 2024, and the regional Flugplatz Koblenz/Winningen airport.

Revenue mechanics are segmented: port operations generate transaction fees on cargo and ship services plus recurring rentals of warehouses (e.g., 770 m² at €3.30/m²) and paved land plots (e.g., 10,700 m² at €2.50/m²/month); public transport runs on regional tariffs; water supply follows regulated utility tariffs; real estate and recreational assets produce subscription-style rentals and admissions; municipal heat planning is funded through federal grants (e.g., €135,478 from the BMWK and €870,950.89 for shore power). Customer mix spans industrial anchor tenants (Contargo, DHL Freight, Schenker, DB Cargo, Aleris, Avangard Malz, Kimberly-Clark, Novelis, REMONDIS), municipal residents and businesses across Koblenz and surrounding municipalities, and the City of Koblenz administration as project owner of the heat transition. Profitability is reported at €9.3M for 2025 against a prior-period record of €18.8M; revenue is not publicly disclosed.

The company is governed as a private limited liability company (GmbH) registered in Koblenz (HRB 41, DE148721821), with Managing Director Lars Hörnig (recently re-elected to the VKU Rheinland-Pfalz state board and under an extended contract). It holds minority participation in Windpark Westerwald, and as of late 2024 has launched the KO-Solar joint venture and the Klimahafen Koblenz industrial cooperation network to advance decarbonization of port-side industrial heat and power.

Broad incumbents

• Stadtwerke Hamburg: Hamburg's municipal utility covering energy, district heating, water, and port-adjacent services. A broader incumbent than SWK but comparable as a large German Stadwerke with port-city municipal mandates.
• DB Cargo AG: Europe's largest rail freight operator. A Rheinanschlussbahn partner at Rheinhafen but also a much broader rail-freight incumbent across Germany with overlapping terminal infrastructure interests.
• Frankfurt Main Airport (Fraport) — local airport analog: While much larger and publicly listed, Fraport illustrates the broader municipal/regional airport operator model that parallels SWK's Flugplatz Koblenz/Winningen subsidiary as a regional aviation infrastructure operator.

Direct peers

• Stadtwerke Köln: Cologne's municipal utility operating public transport, port (Häfen und Güterverkehr Köln), energy, and water services. Closely comparable as a German Stadwerke with port and transit operations.
• Stadtwerke Düsseldorf: Municipal utility of Düsseldorf providing energy, water, public transport, and port-related services. Comparable as a multi-service German Stadwerke in a Rhine-region city.
• Stadtwerke München: Large German municipal utility (Stadtwerke) providing public transit, energy, water, and telecommunications to Munich. Direct structural peer as a 100% city-owned multi-utility platform, though materially larger in scale.
• Contargo GmbH: Container logistics operator running inland waterway and trimodal terminals across the Rhine. Both a customer of Rheinhafen and a direct operational peer in inland container logistics.
• Stadtwerke Frankfurt am Main: Frankfurt's municipal utility providing energy, public transit, water, and bathing facilities (BäderBetriebe Frankfurt). Directly comparable multi-utility municipal platform with similar service lines.
• Duisburger Hafen (duisport): Operator of the world's largest inland port at Duisburg on the Rhine. Directly comparable to Rheinhafen Koblenz as a trimodal Rhine inland port handling containers, bulk, and RoRo cargo with rail and road connections.
• Häfen und Güterverkehr Köln (HGK): Cologne's port and freight rail group operating trimodal cargo handling, similar in scope to SWK's Hafen- und Bahnbetriebe. Directly comparable in inland port operations and connected rail infrastructure.
