2014 Ancillary Service Standards and Requirements Study (Review undertaken by IMO)

Date first published on the Independent Market Operator's website: 24 September 2014

Closing date for submissions: 23 October 2014

Current status: The Final Report was published on 6 November 2014.

Background: In accordance with clause 3.15.1 of the Wholesale Electricity Market Rules, at least once in every five year period starting from Energy Market Commencement the Independent Market Operator (IMO), with the assistance of System Management, must carry out a study on the Ancillary Service Standards and the basis for setting Ancillary Service Requirements for the South West Interconnected System (SWIS) in Western Australia.

The study includes:

  • Technical analyses determining the relationship between the level of Ancillary Services provided and the SWIS Operating Standards set out in clause 3.1 of the Market Rules.
  • Identification of the expected costs that would result from an increase in the requirements for Ancillary Services due to additional Facilities connecting to the SWIS.
  • A cost-benefit study on the effects on stakeholders of providing and using a variety of levels of each Ancillary Service.
  • A public consultation process.

An independent consultant, ROAM Consulting, was engaged to assist the IMO with the 2014 Study and has prepared a Draft Report for public consultation. During the course of the Study ROAM Consulting was acquired by Ernst & Young, and the group now operates under that name.
