ASEW

What ASEW does

ASEW (Arbeitsgemeinschaft für sparsame Energie- und Wasserverwendung) is a Cologne-based non-profit member network serving approximately 400 German municipal utilities (Stadtwerke). Formally structured as a civil law partnership (GbR) with a separate commercial entity (ASEW Energie und Umwelt Service GmbH & Co. KG) for product sales, it operates under the umbrella of VKU (Verband kommunaler Unternehmen) and is led by Managing Director Daniela Wallikewitz alongside a steering committee chaired by André Dreißen of Stadtwerke Soest. Its function is to act as a knowledge-sharing, procurement, and regulatory-translation cooperative for the German municipal utility sector, helping members navigate energy transition, digitalization, and sustainability reporting requirements.

The core product is the "StadtWerkZeug" catalog, containing 150+ ready-to-use assets: contract templates (Vertragswerke), information packages (Info-Pakete) covering German energy regulations such as EnEfG and GEG 2024, NPV-based calculation tools for PV and heat pump proposals, customer-facing brochures, explanatory videos, lead-capture forms, and the online "ASEW.Rechnungserklärer" invoice explanation application. Supporting technology is conventional web infrastructure — a SharePoint-based member portal, an e-commerce storefront, and customer data management via the third-party open.INC platform. Complementary offerings include 94 annual events (workshops, webinars, experience exchanges), standing working groups (Arbeitskreise), individual consulting, the "Stadtwerke-Initiative Klimaschutz" climate protection initiative, and an IoT provider matching service.

Revenue is generated through a hybrid, non-profit model: recurring membership fees from ~400 Stadtwerke, fee-based training (€199 for members, €399 for non-members per event), product sales through the StadtWerkZeug shop (many products free for members, paid for non-members), and individual consulting. The go-to-market is member-driven and event-driven rather than sales-led. No external funding, private equity investment, or public listing is indicated.

Expansion highlights5 records

Broad incumbents

• BDEW (Bundesverband der Energie- und Wasserwirtschaft): Germany's largest energy and water industry association, covering utilities of all ownership types (not only municipal). Comparable as an industry-association peer providing policy, regulatory, and knowledge services to utility members.
• Deutsche Energie-Agentur (dena): Germany's energy agency, applying expertise in energy transition, efficiency, and renewables with consulting, studies, and program management. Comparable as a policy-adjacent energy advisory body serving similar stakeholders.
• Verbraucherzentrale Bundesverband: Federation of German consumer advice centers providing consumer-facing energy advice, brochures, and tools—comparable in mission (energy information dissemination) and consumer-communication template approach, though targeting end consumers rather than utilities.
• VKU (Verband kommunaler Unternehmen): Parent-association and broader trade body of German municipal utilities. Operates as the umbrella for ASEW and the wider Stadtwerke sector, providing policy advocacy, regulatory representation, and industry intelligence—comparable in mission but broader in scope.

Regional players

• Energy Cities: European network of cities and municipal energy stakeholders focused on the energy transition. Comparable as a peer network organization, but operating at EU level rather than national (German) scope.
• EA.NRW (EnergieAgentur NRW): Regional energy agency for North Rhine-Westphalia providing consulting, networking, and information services to municipal utilities and municipalities. Comparable in services but limited to one German federal state.

Emerging players

• EnergieZENTRUM: Consulting and project organization supporting municipal utilities and municipalities on energy transition projects. Comparable in target customer (Stadtwerke) and service offering (consulting, project support).

Direct peers

• AGFW (Der Effizienzverband für Wärme, Kälte und KWK): German efficiency association for district heating, cooling, and CHP, focused on municipal heat networks. Comparable as a sector-specific knowledge and member-network organization supporting utility operators with regulatory and operational guidance.
• DENEFF (Deutsche Unternehmensinitiative Energieeffizienz): Industry initiative advancing energy efficiency in Germany, providing policy advocacy, networking, and knowledge exchange for utilities, energy service companies, and efficiency providers. Comparable as a focused, network-based efficiency advocacy organization.
• co2online GmbH: Non-profit climate-protection advisory organization funded by the German government and utilities, providing energy-saving consulting, consumer communications, and efficiency campaigns to municipal utilities—highly comparable in mission and target audience.
