Demands on thermal power plants in the liberalised energy market
In the liberalised energy market, a diversified set ('mix') of power plants will be needed. By investigating present and anticipated future criteria in detail, available technologies and outlines of further development are identified and discussed. Among them, concepts for efficiency-optimised base load plants as well as units with an improved cycling operation capability are both attributed to a specific valued benefit. Following the demand for a significant reduction of the overall greenhouse gas emissions, centralised power plants fed by fossil fuels and modified for retention of CO2 are needed to guarantee a supply of energy at moderate costs in the 21st century.
