Consultation on enhancements to market for Financial Transmission Rights


We are seeking feedback on 12 options for improving the Financial Transmission Rights (FTRs) market, which could help participants manage locational price risk more easily and effectively. 

We are seeking feedback to determine which, if any, of the 12 options are worth considering further. We think eight of the options could be led by our service providers, and we are seeking high-level comment on those options to inform their priority. 

We are seeking detailed comments on the other four options. One of these is to allow Australian-based parties to directly trade FTRs. We think it could have efficiency benefits for the FTR market and wider hedge market. However, increases in participation could make it harder to acquire FTRs, since there is a limited supply. Therefore, we are also seeking feedback on options that could address the inherent supply constraints.

Submissions close at 5 pm on Tuesday, 9 May 2017.

Normal Frequency Management – Strategic Review information paper


We are reviewing the arrangements for managing normal frequency to investigate options to further promote the efficiency limb of the Authority’s statutory objective. Matters to be considered include the asset owner performance obligations for generators, the proposed national market for frequency keeping, cost allocation, and dispatch processes.

We have published an information paper that includes results of analysis completed by the Authority, supported by detailed technical reports from the system operator. Publishing the paper provides an opportunity for interested parties to provide feedback on the proposed future arrangements for normal frequency management.

Submissions close at 5 pm on Tuesday, 9 May 2017.

Security and Reliability Council appointments


We recently sought nominations to fill three positions on the Security and Reliability Council (SRC). The three positions relate to one resignation and two expiring memberships, including the chairperson.

The SRC Charter specifies a range of selection criteria and requires the SRC as a whole to include a balance of knowledge regarding the long-term interests of consumers, power systems engineering and analysis, generation and demand-side management technologies, and regulatory and economic analysis. 

We received nominations from a number of highly qualified candidates and we are pleased to announce:

  • the reappointment of Mike Underhill as independent chairperson, term expiring 31 March 2020
  • the reappointment of Barbara Elliston as an ordinary member, term expiring 31 March 2020
  • the appointment of Marc England as an ordinary member, term expiring 31 March 2019.

SRC member biographies are available on our website.
