DEAG Dillier Energie AG

What DEAG Dillier Energie AG does

DEAG Dillier Energie AG, now operating as DEAG Energie GmbH following a January 2026 business transfer, is a Swiss specialist in power generation systems founded in 1998 by Daniel Dillier. The company, headquartered in Kägiswil near Sarnen, designs, sells, integrates, and services Stromerzeuger (power generators) ranging from 2 to 2,500 kW, Notstromaggregate (emergency power systems) in open, sound-insulated, or container configurations, and industrial diesel motors from Scania and MAN. Its technology stack centers on industrial diesel engines (Scania 9-16 liter V8s producing 200-566 kW, MAN D2862 V12), supplemented by proprietary engineering including NEMP-protected generator systems certified by BABS and tested at the armasuisse Spiez laboratory, hybrid battery/diesel solutions for emission-free tunnel operation, in-situ particle filter regeneration systems, and ultra-silent Whisper Cube / Event Master enclosures (<52 dB(A) at 7m).

The company serves a predominantly public-sector and critical-infrastructure customer base. Named reference customers include Swiss Federal Railways (SBB), Rhätische Bahn, Matterhorn Gotthard Bahn, Lake Geneva shipping operator CGN, Vierwaldstättersee shipping (SGV), KVA Bern waste-to-energy, BABS-certified civil defense shelters, multiple municipal water utilities (Stäfa, Küsnacht), fire departments, Kantonspolizei Luzern, and enterprises such as Kibag, Marti AG, RIZ AG, Maxon, and Aebi Suisse. DEAG holds the status of sole Swiss distribution partner for Scania industrial engines and is a distribution partner for MAN, with additional reseller arrangements for TecnoGen, Denyo, Honda, and Nanni marine motors. Customer verticals span railway, marine, civil defense, municipal water, construction, IT/data center, industrial, agriculture, and event/temporary power.

DEAG operates with a lean team of approximately 3-5 employees and reaches customers through direct sales, technical consultation, and industry referrals. Revenue streams include hardware sales (new and used generators, industrial motors), professional services (maintenance, repairs, spare parts), and rental of generators and mobile lighting. Pricing is quote-based for engineered solutions; selected used/new smaller units are listed publicly from CHF 3,285 to CHF 6,980+, while large engineered systems command substantially higher project values. In January 2026, founder Daniel Dillier transferred the business to DEAG Energie GmbH, with Managing Director Rainer Krüsi (in role since 2013) continuing to lead operations, marking a generational handover for the 28-year-old business.
