How much Emergency Reducible Generation (ERG) is there if Eco Min is 100 and Emergency Min is 75?

To determine the amount of Emergency Reducible Generation (ERG), you need to understand the relationship between the Eco Minimum (Eco Min) and the Emergency Minimum (Emergency Min).

The Eco Min represents the minimum generation level for economic efficiency, while the Emergency Min represents the minimum generation level required to ensure system reliability during emergency conditions.

The ERG can be calculated by subtracting the Emergency Min from the Eco Min. In this case, if the Eco Min is set at 100 MW and the Emergency Min is at 75 MW, you can calculate the ERG as follows:

ERG = Eco Min - Emergency Min

ERG = 100 MW - 75 MW

ERG = 25 MW

Thus, when the Eco Min is 100 and the Emergency Min is 75, the amount of Emergency Reducible Generation (ERG) is 25 MW. This indicates the generation that can potentially be reduced to maintain a balance in the event of an emergency while still complying with the minimum requirements for reliability.
