Operating ratio and cost of coal power generation

coal-fired power plants can cause thermal and pressure stresses. Over time, these can result in premature component failure and increased, necessary maintenance. Starting a unit, increasing its output, or operating at part load can also increase emissions compared to non-cyclic operation. Assessment and control of operation and plant maintenance costs play a major

Flexibility in thermal power plants - Agora Energiewende

when gas is competing against coal, the flexible operation of coal power plants can lead to increased CO 2 emissions. In those systems, an effective climate policy (e.g. carbon pricing) remains a key precondition for achieving a net reduction in CO 2 emissions. Existing thermal power plants can provide much more flexibility than often assumed, as experi-ence in
