Independent Market Operator

The Independent Market Operator (IMO) is an industry-funded organisation that, until the changes announced by the Minister for Energy, the Honourable Dr Mike Nahan MLA, in September 2015, was appointed to operate and develop the Wholesale Electricity Market and the Gas Services Information functions in Western Australia.

Since the Minister's announcement in September 2015, all of the IMO’s primary functions under the Wholesale Electricity Market Rules (WEM Rules) and the Gas Services Information Rules (GSI Rules) have been progressively transferred to other organisations.

The IMO continues to have carriage of a transitional compliance function under the WEM Rules which involves an application to the Electricity Review Board for an alleged contravention of the WEM Rules by a participant.

Market Operations and System Management

On 30 November 2015, most of the IMO’s operations, forecasting and information services functions under the WEM Rules and the GSI Rules were transferred to the Australian Energy Market Operator.  For information on Wholesale Electricity Market Operations, System Management and the WA Gas Bulletin Board please contact the Australian Energy Market Operator.

Compliance

On 1 July 2016, the IMO’s functions to monitor, investigate and enforce compliance by participants with their respective obligations under the WEM Rules and the GSI Rules were transferred to the Economic Regulation Authority.  Accordingly, all compliance matters should be directed to the Economic Regulation Authority.

Rule Changes

On 25 November 2016, the IMO’s functions to administer, and develop changes to, the WEM Rules and the GSI Rules were transferred to the Rule Change Panel (that was established on 23 November 2016).  For copies of the WEM Rules and GSI Rules, and for enquiries relating to rule changes, please contact the secretariat for the Rule Change Panel, the Economic Regulation Authority.

Market Advisory Committee and Gas Advisory Board

On 25 November 2016, the IMO’s functions to provide secretariat support to, and chair, the Market Advisory Committee (MAC) and the Gas Advisory Board (GAB) were transferred to the Rule Change Panel.  For enquiries relating to the MAC and the GAB, please contact the secretariat for the Rule Change Panel, the Economic Regulation Authority.
