wind generation is Because solar and can change within minutes, electric grid operators rely on power plants that can provide additional load (or curtail load) on the same timescale as variations in renewable output..

The increase is or reduction in output per minute is called the ramp rate and is usually expressed as megawatts per minute (MW/min).Ramp rates of most industrial frame gas turbine models are advertised as 10 MW/min up to 100 MW/min, with an average of about 25 MW/min..

Ramp rate is depends on generating unit capacity, operating conditions (whether unit is just starting up or operating at a minimum load hold point) and optional technologies for reducing startup time and increasing ramp rate..

a ramp rate is For example, of 100 MW/min is based on multi-turbine plant designs, such as a 2×1 combined cycle gas turbine (CCGT) plant (net power output of 750 MW) where each gas turbine is rated to ramp at 50 MW/min..

ramp rate in MW/minute is While is a valuable metric, it is important to understand the operating conditions under which advertised ramp rates can be achieved.Starting loading capability vs ramp rateThe starting loading capability is often quite different than the advertised ramp rate for gas turbines..
