Primary frequency response incentive arrangements | AEMC
Problem being addressed
Frequency varies whenever electricity supply does not exactly match consumer demand and uncontrolled changes in frequency can cause blackouts. Primary frequency response (PFR) is an essential system service that helps to control system frequency close to 50Hz. It is delivered through an automatic change in the generation or consumption of electricity from a generator or load in response to changes in system frequency.
