Short answer: prepare the provider’s legal and public contact details, then compile the name, address and customer composition of every property covered by the registration. Current ERA guidance indicates that individual meter numbers and internal wiring layouts will not be requested at registration, but the meters and supporting records still need to meet applicable requirements.

Why this matters now

Western Australia’s Alternative Electricity Services framework will regulate single property networks, including many shopping centres, commercial buildings, apartment developments, retirement villages and other multi-tenant properties. Providers will need to register with the Economic Regulation Authority, comply with the applicable AES Code and, where they supply small-use customers, meet Energy and Water Ombudsman WA membership and complaint-handling requirements.

PKTR Energy has sought clarification from the ERA about the practical information property owners and operators should prepare. The registration process may be straightforward, but it does not replace the need for accurate metering, transparent billing and clear operational responsibility.

Registration timetable

What information should you prepare?

For the organisation

• Number of non-residential customers
• Number of large customers using more than 160 MWh a year

Will you need to submit a meter register?

The ERA has clarified to PKTR that individual meter numbers and internal wiring layouts are not expected to be requested as part of registration. That should not be read as permission to ignore the metering network. Meters must still meet the applicable legislative requirements, including relevant measurement requirements referenced by the AES Code, and a meter complaint may lead to an audit.

Good records also make it easier to answer customer questions, investigate data issues, reconcile retailer and tenant consumption, plan upgrades and demonstrate how the site is operated.

Registration is only the beginning

Before July 2027, a sensible property-level review should identify the responsible provider, confirm customer categories, map the master meter and sub-meters, check how interval data is collected, document the billing process and assign ownership of customer-protection procedures.

PKTR can help review the metering infrastructure, identify technical risks and turn the findings into a practical readiness plan. Legal responsibility, registration status and formal compliance remain subject to the final service arrangement and applicable rules.
