The Australian Energy Regulator (AER) has released a compliance update for the transmission businesses that provide vital inertia network services and system strength services to keep our national electricity grid in a safe and stable operating state.

The update covers the critical obligations under the National Electricity Rules to meet the relevant inertia shortfalls and system strength gaps as declared by the Australian Energy Market Operator.

In a market where new technologies are emerging and some traditional generation types are retiring, these services are key to keeping the system stable and secure.

We expect transmission businesses to maintain focus on these obligations when procuring the relevant system services.

Participants should review their practices in light of the information set out in this compliance update and amend them as appropriate.
