Frequency Control Ancillary Services (FCAS) play a vital role in keeping Australia’s power grid stable, reliable and secure. As more renewable energy enters the mix, maintaining frequency balance has become more complex — and more important than ever.
This page serves as your general knowledge hub for FCAS — from the market rules that shape participation to the technologies that support compliance and fast frequency response. You’ll also find clear insights, the latest industry updates and practical guidance on metering and monitoring to help you succeed in FCAS markets.
Electricity generators and market operators use Frequency Control Ancillary Services to keep power system frequency within safe limits. By responding instantly to changes in supply or demand, they prevent instability and protect critical infrastructure.
Heavy energy users such as aluminium smelters, mining sites and paper mills participate in FCAS by adjusting their energy consumption in real time. This demand response capability helps balance the grid and opens up new revenue streams for industrial operations.
Wind farms, solar plants and battery storage systems support FCAS markets with rapid-response services that stabilise frequency. This enables renewable projects to meet compliance requirements while boosting asset performance and market value.
In the modern world, where electricity is an essential part of everyday life, the stability and reliability of power systems are of paramount importance. One crucial aspect of maintaining a stable power grid is ensuring the balance between electricity supply and demand.
When discussing energy systems, particularly in the context of the Australian Energy Market Operator (AEMO), the terms resolution and accuracy play crucial roles in ensuring the stability and reliability of the grid.
Battery Energy Storage Systems (BESS) are becoming an important component in the modern electric network. These systems are often combined on-site with renewable energy sources for storing energy during peak production or low demand, and releasing the stored energy during peak demand.
