Australian Energy Regulator engagement

Owner entities in the NEM may be subject to registration, reporting, and exemption processes administered by the AER. Filings depend on asset phase, corporate structure, and rule versions in force at the filing date. Published copies include title, reference number where applicable, and publication date. Internal working papers not intended for the public record are not duplicated here.

When rule changes affect prior interpretations, supplementary notices are added so that version history remains clear for lenders and advisers.

Grid exemption and related determinations

Exemption applications and determinations affecting market participation are listed when cleared for publication. The regulatory milestones asset brief summarises major owner milestones; underlying documents appear in this register when available.

Compliance notices

Compliance notices requiring public action or corrective steps are summarised here with status and closure date when applicable.

Regulatory FAQ

AER listings, exemptions, and public registers.

Are all AER filings downloadable from this site?
Only documents cleared for public release appear with download links when available. Some filings remain restricted to authorised counterparties or require redaction before publication. Use the request form or Contact with your reference numbers.
How are compliance notices displayed?
Notices requiring public action are summarised with status, corrective steps, and closure dates when applicable. Superseded notices remain in the chronology with an archived status for audit purposes.
Does this register replace the AER’s own website?
No. This is an owner-maintained index for convenience. Authoritative copies remain with the regulator. If wording differs, the regulator’s version prevails.

“Having exemption chronology and information-request responses indexed in one owner register reduces time spent reconciling AER mail with project finance data rooms.”
