What must the Frequency Response Measure (FRM) of a Balancing Authority be in order to achieve sufficient Frequency Response?

The Frequency Response Measure (FRM) of a Balancing Authority is critical for maintaining system reliability and stability. To achieve sufficient Frequency Response, the FRM must be equal to or more negative than the Frequency Response Obligation (FRO). This is because the FRO establishes a minimum level of responsiveness required to counteract frequency deviations within the grid.

When the FRM is equal to or more negative than the FRO, it signifies that the Balancing Authority has adequate resources deployed to respond effectively to changes in system frequency. A more negative FRM indicates a stronger capacity to provide downward frequency response, which is essential during events that cause frequency to drop.

The need for the FRM to meet or exceed the FRO is rooted in the balance of electrical supply and demand; any imbalance can lead to frequency instability. Thus, a Balancing Authority must maintain a FRM that not only meets regulatory requirements but also enhances the overall robustness of the power system against fluctuations, ensuring that there is a reliable response to disturbances.
