Fast Frequency Response

About

The Australian Energy The unit must be a generator for the service type: ‘energy’. Loads cannot bid for mandatory restrictions capacity. Market Commission (AEMC Australian Energy Market Commission. The rule maker for Australian electricity and gas markets.) has made a final rule to introduce two new Market Ancillary Services See Relevant Rules or Procedures in the NEM under the existing Frequency Control Ancillary Services (FCAS Frequency Controlled Ancillary Services. A service that balances, over short intervals (shorter than the dispatch interval), the power supplied by generating units and the power consumed by loads.) arrangements, accompanied by additional reporting requirements.

The introduction of these services helps keep the future power system secure and fosters innovation in faster responding technologies helping to lower costs for consumers.
