Titre Ouvrage:Economic aspects of the use of deep geothermal heat in district heating in Poland
Édition:Renewable and Sustainable Energy Reviews, vol. 49, September
All six geothermal heating plants operating in Poland are analyzed including the oldest plant established in 1994 and the newest plant established in 2013 ; the cost structure of geothermal heating plants tends to significantly; however, amortization is the principal operating cost at close to 55% in some cases ;a comparison of the net price of 1 GJ of heat produced by selected heating plants shows that heat produced by brown coal (lignite) plants is the least expensive, while that produced by black coal (anthracite) plants is more expensive ; the prices of heat produced by geothermal heating plants are less competitive, but still more competitive than those of heat produced using natural gas, biomass, and fuel oil.
