This research consists of two studies regarding power generation projects. First based upon hard coal and second as joint optimisation of lignite open pit mine and lignite fired power station. Hard coal spreads as fossil fuels combustion competitiveness measure were calculated based on the typical parameters for the Polish hard coal and lignite power stations. Brown spread calculated for lignite power station generally indicates a higher value than the dark spread for hard coal combustion. Spreads value depend on the efficiency of the power plant. Starting from the same combustion efficiency for coal and lignite proportionately better economic result can be reached when changing old hard coal units on new compared to the investment in lignite-fired units. On the basis of coal and electricity market prices and the estimated cost of lignite production from existing and planned to extraction deposits as in second part of this research we estimate profit from increasing the efficiency of two types of power plants also including different levels of the cost of CO2 emission allowances. Nowadays the efficiency of lignite units in power plants in Poland ranges from 32% to 39% and for hard coal from 34% to 42%. In this research power station efficiency influence on profitability of power generation projects is investigated up to 50 %.
