Energy Policy WA has published the Exposure Draft of Electricity System and Market Amending Rules (Tranche 8). Amongst other amendments, this includes proposed Electricity System and Market Amending Rules to:
- implement a new method for calculation of the Availability Duration Gap, including to:
- increase the Reserve Capacity Target to account for the need for additional Reserve Capacity arising as a result the ESR Duration Requirement protection provisions;
- increase the protection for ESR against an increase in ESR Duration Requirement from five years to ten years; and
- prioritise new Capability Class 1 and Capability Class 3 facilities in the Network Access Quantity framework, if AEMO has determined that further Capability Class 1 and Capability Class 3 capacity would be required to make up a Reserve Capacity shortfall;
- ensure that costs associated with the provision of RoCoF Control Service are appropriately allocated;
- reflect recent changes to the Electricity Industry Act 2004 such as incorporation of the new State Electricity Objectives and replacement of Wholesale Electricity Market Rules with Electricity System and Market Rules;
- implement the policy that only Synergy (or an intermediary acting through Synergy) can associate non-contestable customers with a Demand Side Programme or Interruptible Load.
To see a summary of all other changes, please refer to the Tranche 8 Exposure Draft which can be found by clicking the link below.
Energy Policy WA will be holding a Transformation Design and Operation Working Group meeting on 10 April 2025 to discuss the Tranche 8 Exposure Draft.
Stakeholders are invited to provide written feedback on the Exposure Draft before 5:00 PM (WST) on 24 April 2025 by submitting comments to energymarkets@demirs.wa.gov.au.
