Typical medium-speed reciprocating engines have a ramp rate of about 5 MW/min, but aeroderivative gas turbines have a nominal ramp rate of around 50 MW/min, providing a much faster frequency control response for better grid support. Aeroderivative turbines are designed for high cycling capability, allowing multi-day start/stop cycles.
