Smart Power Generation in Germany –enabling KMW AG to operate profitably in the increasingly volatile power market and provide climate-friendly district heating to the community.


Owing to the broad use of renewable energy sources as well as the utilisation of power generation for district heating, Germany has become one of Europe’s forerunners in the development of its energy system. The municipal energy producer Kraftwerke Mainz-Wiesbaden AG (KMW) recognises the benefits that greater flexibility in the generation of conventional power offers, as the share of renewables in the system steadily increases. Not only does this flexibility guarantee reliable power supply, but it also enables KMW AG to operate profitably in short-term power markets. Wärtsilä’s fast-acting power plant enables KMW AG to operate the plant in short-term markets with competitive prices, resulting in a new revenue stream for the company. Furthermore, KMW AG is complying with the renewed Combined Heat and Power (CHP) Act, whereby Germany has committed to increasing its share of electricity produced by CHP power plants to 25% by 2025. To meet this target, the act favours flexible and environmentally-friendly CHP power plants.
