HEOS Energy

What HEOS Energy does

HEOS Energy GmbH is a German for-profit manufacturer and engineering services provider of regenerative (renewable) energy plants, headquartered and producing at Carl-von-Bach-Straße 8 in Chemnitz, Germany. Founded on June 1, 2007 as a spin-off from sister company IWB Werkstofftechnologie GmbH — itself active in hydropower since 1994 and wind power since 2004 — HEOS inherited accumulated expertise and now designs, produces, and services distributed renewable energy systems across solar, wind, and hydroelectric modalities. Its core proprietary hardware includes two in-house vertical-axis wind turbines (the HEOS H75 at 75 kW and the HEOS V15 at 15 kW) and a dual-axis solar tracker (HEOS HT35-2 at 5.04 kWp, claimed to deliver ~40% higher yield than fixed-tilt PV). Supporting services cover turnkey photovoltaic system planning and installation for rooftops and open areas, redevelopment and automation of river hydroelectric stations up to 1 MW with up to three turbines, wind-power gearbox repair and refit up to 2.5 MW, and industrial component production (CNC machining, blasting, coating up to 22 m / 25 t) executed in cooperation with IWB.

The company generates revenue primarily through project-based one-time hardware sales combined with professional services for planning, assembly, maintenance, and repair; specific pricing is not publicly disclosed and contracts are quoted per project. Go-to-market is direct sales-led, complemented by event-driven demand generation through German federal trade delegations (notably the 2015 Federal President visit to Mongolia) and the dena Renewable Energy Solutions (dena-RES) program, which BMWi co-funded at 45% to help HEOS establish foreign-market reference installations such as the hybrid wind/PV island grid at the Mongolian University of Life Sciences (MULS) in Nart Töv. Customer segments span enterprise energy utilities (e.g., DREWAG Netz GmbH for the Tharandt hydropower station; ENSO AG for Malter and Klingenberg), industrial and agricultural operators, owners of existing renewable assets needing maintenance/modernization, educational institutions in off-grid settings, and residential buyers. The firm holds ISO 9001:2008 and SCC certifications, employs 11–50 people, is privately held with no disclosed institutional investors, and is led by Managing Director Dr.-Ing. Klaus Hoffmann.
