The purpose of the PSSR Standards Review is to implement the Energy Transformation Taskforce’s recommendation to develop an end-to-end PSSR standard for the South West Interconnected System (SWIS), and include this in the Electricity System and Market Rules (ESM Rules).
Energy Policy WA (EPWA), in consultation with a Market Advisory Committee Working Group, has developed a Consultation Paper with a set of proposals to consolidate, streamline and improve the PSSR Standards for the SWIS.
The Paper includes proposals for:
- updated network planning standards for PSSR to evolve and improve their application in the SWIS;
- a revised User Facility Standards Framework, that combines the connection standards in the ESM Rules and Western Power’s Technical Rules, to bring all facilities connecting to the network into one framework;
- revised Technical Requirements (connection standards) to remove barriers to new battery and renewable energy technologies seeking to connect to the SWIS that can provide valuable services to the electricity system;
- a new SWIS System Strength framework to clarify the obligations of the market bodies, and Western Power in particular, to maintain system strength; and
- revised governance arrangements for the updated end-to-end PSSR Standard.
Stakeholders are invited to provide feedback on the proposals before 5:00pm (AWST) 7 August 2025 by submitting comments to energymarkets@deed.wa.gov.au. Late submissions may not be considered.
Any submissions received will be made publicly available on PSSR Standards Review webpage unless requested otherwise
A copy of the Consultation Paper can be found by visiting the Power System Security and Reliability Standards Review web page.
