      Generator Energy Limitation Framework (GELF) Parameters
  • The Energy Adequacy Assessment Projection (EAAP) report provides information on the impact of potential energy constraints, such as water storages during drought conditions or constraints on fuel supply for thermal generation, on supply adequacy in the National Electricity Market (NEM).

    The most recent public EAAP report is combined with the June 2017 Energy Supply Outlook.

    Under the EAAP’s data collation process, all scheduled generators in the NEM are required to submit information to AEMO regarding the effect of energy supply limitations on their production outputs. This data provides a broad assessment of impacts on supply and reliability in the NEM. For more information please review the EAAP guidelines.

    For information about submitting Variable Generator Energy Limitation Framework (GELF) Parameters, see:

    It is important for participants to note:

    • The capacity or energy GELF parameters entered for each scenario should reflect the monthly forecast generation capability in that scenario, and not the generation capability reduction for the scenario.
    • The three rainfall scenarios to be considered in submitting GELF parameters are:
      • Low rainfall scenario – Variable GELF parameters for power stations located in Queensland, Victoria, South Australia and Tasmania should be based on the rainfall experienced between 1 July 2006 and 30 June 2007. Variable GELF parameters for power stations located in New South Wales should be based on the rainfall experienced between 1 June 2006 and 31 May 2007.
      • Short-term average rainfall – Variable GELF parameters should be based on the average rainfall recorded over the past 10 years.
      • Long-term average rainfall – Variable GELF parameters should be based on the average rainfall recorded over the past 50 years, or the longest period for which rainfall data is available, should this be less than 50 years.
    • Participants wanting to receive the EAAP participant reports covering their scheduled generating units and/or hydro power schemes need to subscribe to the “EAAP_Results” file. Participant file subscriptions are managed in the MMS Web Portal via the Data Subscriptions option, available from the Data Interchange menu.
