Final guideline

Our guideline sets out our process and method for how we make contribution determinations under the National Electricity (South Australia) (Firm Energy Reliability and Orderly Exit Management) Regulations 2025 (FERM Regulations).

The guideline explains how we:

• collect and assess information from scheme entities
• calculate annual contribution amounts to be recovered through the scheme
• determine and maintain a minimum prudent cash balance for the FERM Fund
• issue contribution determinations and contribution notices to transmission network service providers. 

The guideline and accompanying communication provide transparency on the AER’s role and processes under the FERM Regulations, including the type of information we may require, the methodology we will apply, and the timing of key steps in the annual contribution determination process.
