Poland, April 9 -- Technology group Wartsila's analysis indicates that the district heating system in Poland could achieve more efficient cost structures through a more optimal choice of generating technology. The operators could achieve this by raising the importance of electricity production to that of heat generation. This could result in strengthened revenue base for district heating operators, which in turn could enable greater flexibility in how the end-user pricing is structured.Combined heat and power (CHP), or cogeneration, technology generates heat and electricity simultaneously in a single, energy efficient process. Most of the heat used in Europe's heating and cooling networks is derived from this technology. However, in Polish ...
