Energy House Germany

What Energy House Germany does

Energiehaus Deutschland B2B GmbH is a Bayreuth-headquartered German energy utility that supplies gas, green electricity (Ökostrom), heat-pump tariffs, and electric mobility infrastructure to property management companies (Hausverwaltungen), residential communities (Wohnungseigentümergemeinschaften / WEGs), commercial businesses, and social institutions. Founded in 2011 and operating as a wholly-owned subsidiary of municipal utility WEMAG AG, the company differentiates through vertical specialization in the real-estate segment, addressing fragmented multi-property energy procurement, meter reading management, heating-cost billing compliance under German energy law, and EV-charging infrastructure planning for residential complexes.

The product portfolio combines commodity energy supply with the EHDE-Ableseportal digital meter reading platform, e-mobility charging infrastructure consulting, and EHDE Campus — an educational platform offering webinars, expert talks, and an IHK-certified property manager training program delivered in partnership with GROSS Rechtsanwälte Berlin. Distribution is built around regional Key Account Managers providing consultative on-site service, complemented by phone/email inside sales and digital self-service. Marketing emphasizes content-led community engagement through the #energiezone blog, downloadable checklists, the "Hausverwalter aufgepasst!" short-video series, and webinar programs reaching over 1,000 participants annually.

The business model is predominantly recurring revenue from multi-year energy supply contracts, supplemented by professional services revenue from EHDE Campus training (Powerpack at 970 EUR plus VAT; individual modules at 120 EUR plus VAT). The company has 11–50 employees and is led by Managing Directors Jochen Affeldt and Michael Hillmann, with Mahmoud Awwad appointed COO in July 2025 to lead digitization and growth. Parent WEMAG AG has committed 661 million EUR to grid expansion and 235 million EUR to renewable energy projects through 2030, providing financial stability and infrastructure leverage that underpin the subsidiary's operations.

Broad incumbents

• GASAG Berliner Gaswerke AG: Berlin-based regional gas and heat utility serving residential and commercial customers. Comparable to EHDE on the gas-supply side and as a regional utility competing for property-management contracts in its footprint.
• EWE Vertrieb GmbH: Large northern German municipal-rooted multi-utility supplying electricity, gas and heat to residential and commercial customers. Comparable to EHDE as a broad incumbent in property-management-relevant energy supply.
• E.ON Energie Deutschland GmbH: One of Germany's largest energy utilities, supplying electricity, gas and increasingly EV/heat-pump solutions to households and businesses. Comparable to EHDE as a broad incumbent competing for the same property-management customers with a wider portfolio.

Direct peers

• ista SE: Major German provider of energy and water submetering, billing and energy services for property managers and housing companies. Comparable to EHDE because both target Hausverwaltungen and bundle metering, billing and energy-related advisory into recurring service contracts.
• KALO GmbH: Digital metering and energy services provider specifically focused on German property managers and homeowners. Directly comparable to EHDE because KALO serves the same Hausverwaltung vertical with metering, billing and energy data workflows.
• Minol Messtechnik W. Lehmann GmbH & Co. KG: German metering and energy services company serving property managers and housing industry. Comparable to EHDE because Minol operates in the same property-management energy value chain (submetering, billing, energy data services).
• Techem GmbH: Germany's leading provider of heating cost allocation and energy services for residential property managers and WEGs. Closely comparable to EHDE because both serve Hausverwaltungen with energy/submetering services, billing workflows, and regulatory compliance support.

Emerging players

• Lichtblick SE: German green electricity and gas supplier with a strong digital/consumer brand. Comparable to EHDE as a green-energy retailer, though Lichtblick targets consumers/SMBs broadly rather than specializing in property managers.
• naturstrom AG: German renewable energy supplier offering green electricity and gas to households, businesses and housing providers. Comparable to EHDE on the green electricity supply side, particularly for environmentally conscious WEGs.

Others

• GETEC Group: B2B energy services provider for residential and commercial real estate in Germany. Comparable to EHDE as a fellow B2B energy specialist focused on housing and real estate portfolios, though GETEC skews toward larger contracts and contracting models.
