+====== Coal efficiency ======
+The data for efficiencies and emissions of the [[coal_more|Coal Power Plants]] with and without [[co2_storage_more_2|CCS]] comes from the NEEDS project. In the report <sup>[[#References|[1]]]</sup>, there are three different forecasts for each technology and year (2025 or 2050): Pessimistic (PE), Realistic optimistic (RO) and Very optimistic (VO).
+Next table includes the efficiencies for the different kinds of coal power plants together with the scenarios that have been selected for the years 2035 and 2050 in the calculator.

+The efficiency of a coal power plant is defined as follows:
+$\eta = \frac{E^-}{Q^+}$
+^$\eta$ |Efficiency [%] |
+^$E^-$ |Electricity produced by the alternator [kWh] |
+^$Q^+$ |Combustion heat from coal (LHV basis) [kWh] |
