Revenue model

1. District Heating Supply (Wärmelieferung): Revenue is generated through the sale of heat energy (Fernwärme) delivered via owned heating plants to tenants of the Wohnbau Group's properties and to third-party customers. Pricing is structured as an annual heating cost statement divided into a base price (30% of total cost, allocated by building heat demand per DIN 4701) and a consumption-based volume price (70% of total cost, allocated by measured consumption per heat meter). Customers pay in 12 equal monthly installments. Additional revenue streams include connection/house connection fees and ancillary charges.

Regional players

• Lechwerke AG: Bavarian regional utility with district heating and CHP operations in the Augsburg/Allgäu region. Similar in operating smaller-scale district heating plants serving residential housing, though based in a different German region (Bavaria).
• N-ERGIE AG: Regional energy supplier for the Nuremberg region operating district heating networks and CHP plants. Comparable in offering regulated heat supply to residential and commercial customers via owned heating infrastructure in a defined service territory.
• Mainova AG: Regional municipal-style utility serving Frankfurt/Rhine-Main with district heating and CHP. Operates similar regulated heat networks to WSB but in a different geography (Hesse) and at larger scale.
• badenova AG & Co. KG: Regional energy supplier for the Freiburg/Southern Baden area operating district heating and combined heat and power. Comparable as a mid-sized regulated district heating operator with municipal utility roots and similar residential customer mix.
• HanseWerk AG: Northern German energy service provider with district heating operations across Schleswig-Holstein and Hamburg metro. Similar in running decentralized heating plants and networks under the German regulatory framework, but serves a different regional territory.

Broad incumbents

• EnBW Energie Baden-Württemberg AG: Large integrated German energy utility with district heating operations as part of a broader portfolio spanning generation, grid, and retail. Comparable in regulatory treatment and CHP exposure, but at much greater scale and diversification.
• E.ON SE: Major German energy group with heat generation and distribution across multiple regions; comparable in operating a regulated utility model with combined heat and power assets, though diversified across power, gas, and networks well beyond heating alone.
• Vattenfall Wärme Berlin GmbH: Subsidiary of Vattenfall operating one of Germany's largest district heating networks (primarily Berlin, Hamburg). A scaled player in the same regulated district heating model as WSB, but at much larger scale and broader geographic footprint.

Direct peers

• Stadtwerke Bonn GmbH: Municipal utility serving Bonn with district heating (Fernwärme) and energy supply. Operates overlapping heating networks in the Bonn area, including Bonn-Bad Godesberg, making it the closest geographic and operational peer to WSB's Heiderhof plant.
• evm (Energieversorgung Mittelrhein) / SWK Stadtwerke Koblenz: Regional municipal utility operating district heating and energy networks in the Koblenz/Mittelrhein region, directly overlapping with WSB's Horchheimer Höhe service zone and serving similar residential and commercial customers.
