Condensing power works as peak load power in the Nordic countries and as reserve capacity for other power generation
Condensing power is used in the Nordic electricity market to even out the fluctuation in demand caused by poor reservoir water years or by other reasons. Therefore, Fortum’s annual condensing power generation also fluctuates considerably depending on the market situation.
Fortum generates condensing power in the Inkoo and Meri-Pori coal power plants in Finland. Fortum is also part owner (30%) in the Karlshamn oil condensing power plant in Sweden (Karlshamn Kraft AB). The plant is operated by E.ON Värmekraft Sverige AB through an operation and maintenance agreement.
What condensing power?
A condensing power plant generates electric energy using mostly coal, natural gas or oil as the fuel source. As in a heat plant, water is heated and turned into steam to rotate a turbine, which in turn rotates the generator. Unlike in combined power and heat production, heat energy left over after the turbine is not exploited in condensing plants. Instead, it is condensed with cooling water.
