Combined cooling, heating and power

Wärtsilä combined heat and power (CHP) plants are designed to meet the customer's specific needs, be it steam generation, district heating, hot or chilled water, or a combination of the above. As flexibility within the power system will be increasingly required in order to integrate growing shares of renewables in a cost-efficient and secure manner Wärtsilä CHP technology, with it’s fast starting and stopping capabilities, can achieve total efficiencies as high as >90%.

Our CHP plants can run on a wide range of liquid, gaseous and bio fuels, all the while securing low emissions and high efficiency. The heat recovery systems used in our CHP plants are of the post engine “hang-on” type, and thus don't directly influence engine performance or operation. The engine will yield the same high electrical efficiency and output, regardless of the rate of heat production.

Depending on the installation specific heating and/or cooling requirements, plant location and the seasonal variations in ambient conditions, the plant can be equipped with standardized heat recovery and chiller solutions, with absorption chillers for heat recovery and electrically driven chillers for covering the peak demands. Wärtsilä lifecycle solutions and performance guarantees ensure optimised efficiency and performance of the plant.
