This paper provides electricity cost price estimates for biomass-based CHP plants and oil shale power plants to be constructed before 2013 and 2015 that can serve as references for more detailed case-specific studies. Calculation results give electricity costs prices under different CO2 quota price levels (for oil shale energetics), different combined heat and power (CHP) plant scales (for biomass energetics), with and without subsidy mechanisms. The impact of subsidy mechanisms on biomass and oil-shale energetics to adoption of biomass energy sources and its move toward grid parity as well as reasonability of available subsidy mechanisms to avoid backing of projects which cover of expenditure without subsidies are discussed.
