AGO AG

What AGO AG does

AGO GmbH Energie + Anlagen is a German engineering contractor that designs, plans, and builds customized energy supply systems for industrial customers and municipalities. Founded in 1980 and headquartered in Kulmbach, Bavaria, the company delivers decentralized power generation, industrial heating, cooling, and ventilation systems, with a particular focus on energy efficiency and industrial waste-heat recovery. AGO operates as a wholly-owned subsidiary of RheinEnergie, a major German energy utility, and serves enterprise customers across manufacturing, food and beverage, healthcare, and energy infrastructure, including EnBW, E.ON, Bosch, Molkerei Gropper, and Diakoneo.

The company's technology portfolio is built around two proprietary thermotechnical products — the AGO Congelo absorption refrigeration machine and the AGO Caldora industrial heat pump — which enable industrial sites to convert waste heat into usable cooling or large-scale heating, reducing both energy costs and CO2 emissions. Beyond these proprietary products, AGO executes full Anlagenbau (plant construction) projects across power generation, heat supply, refrigeration, and HVAC using its own in-house construction managers and technicians rather than subcontractors, supporting quality control and on-time delivery for complex, custom-engineered installations. The company positions itself as manufacturer-independent, developing technical and economic concepts free of vendor lock-in to optimize customer outcomes.

Revenue is generated through three streams: one-time project fees for plant engineering and construction, recurring revenue from energy contracting arrangements (where AGO supplies ongoing energy to customer sites), and ongoing service and maintenance contracts including a 24-hour disturbance response service. Pricing is custom project-based and not publicly disclosed. The go-to-market is direct enterprise field sales with technical consultation, supported by participation in industry trade shows (HEATEXPO), technical webinars, Fraunhofer IEG seminars, and project-based PR activity.

Core offering

AGO designs, plans, and builds highly efficient, decentralized energy supply systems — including power generation, heating, cooling, and ventilation — for industrial customers, commercial facilities, and municipalities. The company executes projects with its own construction managers and technicians, sells proprietary Thermotechnik products (Congelo absorption cooling machine and Caldora industrial heat pump), and provides ongoing contracting, service, and 24-hour maintenance.

Product overview

AGO GmbH Energie + Anlagen offers a portfolio of energy supply solutions centered around two proprietary Thermotechnik products — the AGO Congelo Absorptionskältemaschine (absorption cooling machine) and the AGO Caldora Industriewärmepumpe (industrial heat pump) — complemented by a full-service Anlagenbau (plant construction) division that delivers decentralized power generation, heat supply, cooling technology, and ventilation/air conditioning systems. The company operates as a manufacturer-independent contractor, designing sustainable energy concepts and executing them with in-house construction managers and technicians. The Thermotechnik products enable customers to utilize waste heat intelligently, while the broader Anlagenbau services address the complete lifecycle of energy infrastructure projects.
