1. A method for operating a power plant for generating energy, comprising:
exchanging heat between at least one internal combustion engine and a district heating system via a first cooling circuit fluidly coupling the at least one internal combustion engine with the district heating system in a heat exchange relationship, wherein the at least one internal combustion engine is configured to deliver a mechanical power by burning a fuel, wherein exchanging heat via the first cooling circuit comprises cooling the at least one internal combustion engine and heating the district heating system via the heat exchange relationship between the district heating system and the at least one internal combustion engine; and
exchanging heat between at least one additional cooler and the at least one internal combustion engine via a second cooling circuit, wherein exchanging heat via the second cooling circuit comprises cooling the at least one internal combustion engine in response to a transient performance requirement for the at least one internal combustion engine.
