Espoo has set a goal to abandon the use of coal in its district heating system by year 2025. The local operator is producing major share Espoo's heat demand with combined and power units, but large that thermal capacity will be closed plan replace down renewable fuels, pumps waste utilisation. this paper simulate impacts these emission reductive acts on production costs CO 2 emissions system. possibility utilising from data centres evaluated. results show abandoning city's leads significant reduction small increase annual costs.
