Duobloq Energie GmbH

What Duobloq Energie GmbH does

Duobloq Energie GmbH is a German decentralized energy utility (dezentraler Energieversorger) founded in February 2013 as a joint venture between BHK-Holding GmbH and meistro Energie GmbH. The company designs, finances, builds, owns, and operates decentralized energy generation assets — primarily combined heat and power (CHP/BHKW) units, wood chip and pellet boilers, photovoltaic systems, large-scale heat pumps, and EV charging infrastructure — on behalf of commercial and public-sector clients under long-term contracting and equipment leasing arrangements. Customers include universities, schools, hospitals, hotels, correctional facilities, Deutsche Bahn, and municipal institutions across Germany, with the company having executed over 500 projects cumulatively.

The core product portfolio is organized around DUOBLOQ | Wärme+ (heat delivery contracting with full plant operation), DUOBLOQ | E-Mobility (EV charging infrastructure as a service with roaming billing), DUOBLOQ | Wärme+Strom (sector coupling combining heat, cooling, electricity, and e-mobility), DUOBLOQ | Anlagen-Pacht (equipment leasing for decentralized self-supply), and DUOBLOQ | KWK-Nutzungsüberlassung (CHP usage transfer). Supporting offerings include Mieterstrom (tenant electricity), Nahwärmenetze (district heating networks), and Quartiersversorgung (neighborhood-scale energy ecosystems).

The revenue model is predominantly recurring: long-term heat supply contracts charge customers consumption-based fees after commissioning, equipment leasing generates monthly recurring payments, and EV charging yields transaction fees plus host contracting fees. The company operates with a sales-led, enterprise field-sales motion through four regional competency centers (Ingolstadt HQ, Berlin branch, and partners in Saxony, Rhineland-Palatinate, and Brandenburg). Headcount is exceptionally lean at 5 employees, with execution heavily reliant on partner engineering firms (e.g., PEES Ingenieurbüro) and competency-center operators.
