AggerEnergie GmbH

What AggerEnergie GmbH does

AggerEnergie GmbH is a German regional multi-utility founded in 1926 and headquartered in Gummersbach, North Rhine-Westphalia, serving residential, business, and industrial customers across nine municipalities in the Oberbergisches Land district (Gummersbach, Marienheide, Bergneustadt, Overath, Engelskirchen, Wiehl, Reichshof, Waldbröl, Morsbach). The company's core offering consists of regulated electricity, natural gas, and drinking water distribution — for which it holds DIN EN ISO 9001, ISO 50001, ISMS, and DVGW TSM certifications — complemented by a growing renewable and e-mobility portfolio including photovoltaic systems (residential, balcony, commercial, and ground-mounted), heat pumps, wallboxes, public EV charging, e-bikes, and BAFA-listed energy audits per DIN EN ISO 16247. The company distributes through a hybrid model: physical customer info offices in four locations, field service technicians, an online customer portal, an Inbetriebsetzungsportal for certified installers, a 24/7 service hotline, and the Family & Friends referral program.

The business model is built on subscription recurring revenue from energy and water supply, supplemented by transactional hardware sales (PV systems, heat pumps, wallboxes) and professional services (energy audits, cooking studio, event ticketing). AggerEnergie's GTM motion is community-led, anchored by 100 years of regional presence, sponsorship of VfL Gummersbach handball Bundesliga, school energy education programs, Stromwerkstatt museum partnerships, and a children-focused cooking studio (KiKoKu). The company operates with 42 employees, is structured as an independent private limited company (GmbH) under a supervisory board chaired by Till Cremer (who also serves on the Rhenag board), and is currently led by Managing Directors Dr. Andreas Esser and Jörg Bukowski following Frank Röttger's retirement in May 2026 after 20 years at the helm.
