Since the end of 2017, CHP funding for medium-sized installations with electrical output between 1 and 50 MW and for innovative CHP systems has been auctioned. The key points of this auction-based system have been included in the CHP Act since the beginning of 2017. 100 MW of installed CHP capacity is being auctioned on both 1 June and 1 December. The first auction round ended on 1 December 2017.

A new funding category which will cover innovative CHP systems will also be introduced. Innovative CHP systems combine flexible CHP plants with renewable heat, for example from solar thermal installations or heat pumps, which considerably lowers their greenhouse gas emissions. Innovative CHP systems therefore show ways in which CHP installations can remain a viable option for generating electricity long into the future.
