Independent auditor's assurance report  \nModified opinion  \nWe have undertaken a reasonable assurance engagement on ATCO Gas Australia Pty Ltd’s (ATCO) compliance, in all material respects, with the conditions of its Gas Distribution Licence (GDL8) (the Licence) and relevant legislative obligations for the period 1 July 2022 to 30 June 2025. Our evaluation was made against the licence obligations listed in the relevant versions of the Economic Regulation Authority’s (the ERA) Gas Compliance Reporting Manual (the Reporting Manual) and in accordance with the ERA’s March 2019 Audit and Review Guidelines: Electricity and Gas Licences (the Guidelines) .  \nIn our opinion, based on the procedures we have performed and the evidence we have obtained, except for the effects of the matter described in the Basis for modified opinion paragraph below, ATCO has complied, in all material respects, with its licence conditions and relevant legislative obligations for the period 1 July 2022 to 30 June 2025.  \nBasis for modified opinion  \nDuring the period 1 July 2022 to 30 June 2025, ATCO did not comply with the applicable licence obligations as outlined below:  \n\n| Reporting Manual number and Licence obligation |  | Description |\n| --- | --- | --- |\n| 226 | Compendium clause 7.5\u003Cbr>A distributor who disconnects or interrupts a customer’s supply address for emergency reasons must provide a 24 hour emergency line and use its best endeavours to restore supply as soon as possible.\u003Cbr>to 30 June 2024 (replaced by 250A) | FY23\u003Cbr>On 13 July 2022 ATCO identified an instance where a power outage and subsequent malfunction of the backup system resulted in the 24-hour emergency line being unavailable from 1.00am to 7.00am.
