Firm frequency response (FFR)
FFR creates a route to market for providers whose services may otherwise be inaccessible. The FFR service gives us and service providers both a degree of stability against price uncertainty under the mandatory service arrangements.
FFR providers must:
- have suitable operational metering;
- pass the FFR pre-qualification assessment;
- deliver minimum 1MW response energy;
- operate at their tendered level of demand/generation when instructed (in order to achieve the tendered frequency response capability);
- have the capability to operate (when instructed) in a frequency sensitive mode for dynamic response, or change their MW level via automatic relay for non-dynamic response;
- communicate via an automatic logging device; and
- be able to instruct and receive via a single point of contact and control where a single FFR unit comprises of two or more sites located at the same premises.
