The Authority has completed a review of the wholesale market issues during spring 2018.

This review gives an overview of the events of spring 2018 and covers specific issues that arose but were outside the scope of the UTS decision paper for the UTS claimed 8 November 2018. These issues include:

  • the November HVDC outage,

  • thermal generators offer behaviour,

  • the hedge disclosure database, and,

  • availability of public information on gas production.

Both the 2018 and the 2019 UTS claims have had an impact on the timing of this report being published, as they took priority over this work.
