Allam cycle gas turbine system of 350 MW will have a 2-3 hour start-up from cold. Electrical turn-down is 100% without a drastic loss of efficiency, yet still off loads CO2 produced from hot stand-by operation to a pipeline. Will load follow with a ramp of 3-5% per minute.
Thank you. I did not know current technology.
Yet, isn’t it true that a non producing backup power source will take up to a few hours to come online after a wind calm, or a storm, reduces alt energy, so the turbine needs to be running on standby all the time to prepare for the immediate energy needs?
