Core Technical Capabilities That Support Emergency Responses

Ramp Rates andStartup Speed

Natural gas power plants, sucularly combinate-cycle and simple-cycle gas turbine units, can accesse full generating capacity in signitantly less time than coal or nuclear facilities. Simple- cycle turbine can go frem cold start to full load in as little as 10 tlo 15 minutes, while combinate -cycle plants typically require 30 to 60 minuts for complete -ute -up and synchizatio.

Dispatchability andd Load Following

Beyond startup speed, natural gas plants offer exceptional dispatchability. They can ramp output up and down with minimal efficiency loss, allowing grid operators to match generation with the uncertain and fluktuating distread that often exists during emergency conditions.
