RESERVES IN POWER PLANT

In a power plant a reserve generating capacity which is in operation but not in service is (A) hot reserve.

GETTING TO KNOW MORE ABOUT RESERVES IN POWER PLANT:

* In a power system, hot reserve refers to reserve capacity that can be made available fast. For example, we have a 100 MVA hydroelectric generator that currently only delivers 70 MVA. We have a 30 MVA hot reserve in this scenario, which can be loaded quickly by just opening the hydro turbine valve.

* The operational reserve in electrical networks is the producing capacity available to the system operator in a short period of time to satisfy demand in the event that a generator fails or there is another interruption in the supply.

* Most power systems are built so that the operational reserve is always at least the capacity of the largest supplier plus a portion of the peak load under normal conditions.
