In 2018, coal-fired power plants accounted for just 28% of the total electricity produced in the U.S., while natural gas and oil's share increased to 35% and non-hydro renewable's share to 10%. This shift, which shows little sign of slowing, is creating both new opportunities and challenges for stakeholders.
However, current coal-fired power generation is in competition with renewable energy and thus generation has shifted in many countries from baseload to load following mode necessitating flexibility in power plant operations. As such, frequent cycling of coal-fired power plants can cause thermal and pressure stresses.

Table 1 summarizes the key parameters of the power plant Voerde and the dynamic power plant model, respectively. The minimum load of 25% is determined by the firing system in two-mill operation (four-mill operation in full-load). A reduction of the minimum load could lead to the occurrence of unstable combustion.
The coal-fired power plant industry is a national enforcement priority of the US EPA. On November 3, 1999, the Department of Justice and the Environmental Protection Agency announced the filing of civil complaints against seven electric utility companies operating coal-fired power plants in the Midwest and Southeast.

Coal-fired plants in particular have been identified as a large source of CO 2 …
coal-fired power plant is feasible to reduce the minimum operation load, and by optimizing the MSES system scheme, it is possible to achieve higher efficiency with higher investment cost, there ...
The heat-controlled operation mode narrows the power regulation range of coal-fired CHP plants [14]. Consequently, a large amount of renewable power is abandoned because of the mismatch between consumer demand and power supply in the power grid, especially when coal-fired CHP plants take a dominant share of installed …
A generic (non-plant specific) 300 MW net subcritical coal-fired power plant is developed and used to simulate flexible operations at different ramp rates using a coordinated control system.
