Dispatchable generation
Dispatchable plants have varying startup times, depending on the technology used and time elapsed after the previous operation. For example, "hot startup" can be performed a few hours after a preceding shutdown, while "cold startup" is performed after a few days of inoperation. The fastest plants to dispatch are grid batteries which can dispatch in milliseconds. Hydroelectric power plants can often dispatch in tens of seconds to minutes, and natural gas power plants can generally disp
