AEMO Request for Information for reactive power Non-market Ancillary Services in VIC

For the current Victorian Reactive Power Support Regulatory Investment Test – Transmission (RIT-T), AEMO have completed the first stage which is the Project Specification Consultation Report (PSCR)1 which was published on 15 May 2018.

Studies have confirmed that there is a need for absorbing reactive power which can suppress the high voltages in the Victorian transmission network during low demand periods. This need is driven by recent changes to the network operating conditions, as well expected changes in the planning timeframe.

In addition to conventional network options to suppress high voltage, by use of reactive power plant such as reactors, SVC’s or synchronous condensors, non-network options, including demand response, load shifting and co-ordinated charging of decentralised storage during periods of low demand will equivalently increase the demand in Victoria thereby reducing the high voltages and the need for network options.

AEMO is seeking information and proposals for Non Market Ancillary Services from NEM registered participants to suppress high voltages during low demand periods in Victoria to facilitate the analysis of potential solutions in the RIT-T. Participants include grid-connected generating units with an absorbing reactive power capability higher than the requirement stipulated in the agreed performance standards that have the capability to provide additional absorbing reactive power; or dispatchable load, storage or  any other equipment that have the capability to be dispatched or provide additional absorbing reactive power.

INFORMATION AND PROPOSALS ARE INVITED for the provision of Non-Market Ancillary Services from NEM registered participants with generating units, dispatchable load, storage or any other equipment located around Moorabool, South Morang, Geelong, Sydenham or Keilor terminal stations that have the capability to be dispatched to suppress high voltages during low demand periods. 

Information and proposals must be submitted in accordance with the Request for Information below by 5:00pm on Monday 13th August 2018.

It is requested that Recipients submit any questions related to the RFI to The procurement process will begin with AEMO seeking and evaluating information and proposals from potential NMAS providers. The timetable below lists indicative timeframes for the RFI process:

Key Activities Target Dates
Request for Information issued 12 July 2018
Information and proposals due 13 August 2018

Recipients should note that this web page will be updated if addenda to the RFI are issued. Recipients should make a point of regularly checking this web page to ensure that they are equipped with the most up-to-date information.
