KAMAT takes stock after one year of operating own combined heat and power plant

It has now been a year to the day that KAMAT receives electricity and heat for the factory via combined heat and power through its own combined heat and power plant. Time to take stock. Which benefits has the use of the combined heat and power unit brought to the company? What contribution has KAMAT made to the energy transition with it?

Theoretically generated electricity for 20 households

“The numbers speak for themselves. The machine has generated 90,800 kWh of electricity - and is currently running at 9.6 kW, i.e. with about 50% performance. 20 kW x 24 hours x 365 days, that corresponds to 175,200 kW hours pa, with which we run at around 50%. That's not bad at all, better than I thought,” as managing director Dr.-Ing. Andreas Wahl says. “A single-family house has a consumption of maybe 4,000 to 5,000 kWh pa - we theoretically supply 20 houses or households with electricity. We therefore produced an impressive amount of electricity ourselves as a by-product of heating,” Wahl continues.

Whether KAMAT has thereby reduced its CO2 footprint - one can safely argue, but KAMAT burns gas to generate electricity and heat. "If you want take it this way, we would have burned the gas in the heater to generate heat anyway," says Wahl without trying to gloss over it.

Combined heat and power plants - briefly explained

Combined heat and power plants (CHP) supply electricity and heat at the same time. Because they work on the principle of combined heat and power. This makes combined heat and power plants attractive heating systems, especially with regard to climate protection. The Combined Heat and Power Act therefore specifically supports the particularly low-CO2 generation through gas CHP.

According to the German Federal Ministry for Economic Affairs and Energy (BMWI), “CHP systems are supposed to reduce emissions by four million tonnes of CO2 in this way and thus make an important contribution to achieving the 40 percent savings target by 2020.” (see BMWI website)

Cogeneration creates this by simultaneously converting the energy used into mechanical or electrical energy and usable heat within a thermodynamic process. “The heat produced in parallel to the generation of electricity is used for heating and hot water preparation or for production processes. The use of CHP reduces the use of energy and carbon dioxide emissions.“ (Source:

Active contribution to minimising CO2 emissions

KAMAT is definitely convinced of its investment in its own CHP and, after a year of operation, proud to be a medium-sized company in Germany who helps minimising carbon dioxide emissions worldwide and thus making its active contribution within the framework of the voluntary commitment of the German economy.
