    Consultation on the Market Development Advisory Group's Options Paper - Price Discovery in a Renewables-Based Electricity System

    Closed

    06 Dec 2022 – 06 Mar 2023  

     

    The Market Development Advisory Group (MDAG) is undertaking a project to understand how price discovery would work in the New Zealand wholesale electricity market (including spot and hedge markets) under a 100% renewable electricity system.

    MDAG is made up of 10 representatives from the electricity sector who provide independent advice to the Authority on issues in the Authority’s work programme that primarily relate to pricing and cost allocation, risk and risk management, and operational efficiencies.

    The options paper proposes a range of options where change could be warranted as we transition towards 100% renewable electricity supply.

    The paper is structured around the following key areas for future action, each with multiple options for consideration, as noted below:

    • Ensuring reliable and efficient operational coordination
    • Ensuring effective risk management and efficient investment
    • Lifting demand-side participation
    • Strengthening competition
    • Increasing market confidence

    The Authority and MDAG recognise that the sector has a key role to play as we transition to a 100% renewable electricity system, and many options in the paper will impact sector participants. The Authority and MDAG welcome feedback on all options.

    The MDAG will consider submissions on this consultation before developing final recommendations for the Authority in mid-2023.

    Submissions should be emailed to MDAG@ea.govt.nz by 5:00pm Monday 6 March 2023.

    Cyclone Gabrielle – to request an extension to the submissions deadline please email: MDAG@ea.govt.nz

    Price Discovery in a Renewables-Based Electricity System options paper is available here.
