The flexibility of Gas-fired thermal #power plants refers to the speed and extent to which they may be ramped up or dispatched, according to the power demand needed to balance the load and variable supply. This power demand is called residual or netload – the total power demand minus the output of variable #renewableenergy (VRE). From a technical perspective, the flexibility of gas-fired thermal power plants comprises three different dimensions: 1. The #minimum_load represents the lowest load level at which the power plant can operate under stable conditions and without other supporting fuels. The ability to operate at a low minimum load reduces losses at times of low (or even negative) prices and avoids shutdown and subsequent start-up. Shutdown and start-up cycles cause #thermal_stress to equipment (due to rapidly changing temperatures), adding costs for maintenance and repair as well as shortening plant or equipment lifetime.
