This theses evaluates combined heat and power system powered by liquefied natural gas. To do so, one has to look at available CHP technologies and systems for LNG handling and storage. The aim of this work is to determine required heat power output of CHP and volume of LNG reservoir by analysing an arranged annual diagram of heat production. Hereinafter, a CHP plant and LNG reservoiar are put in space and evaluated by means of economics. It turns out, that sales price of heat and reference cost of electric energy, do not provide suffcient income for system to make profit.
