Report purpose

This report provides AEMO Australian Energy Market Operator's calculated effective temperature, effective degree day (EDD Effective Degree Day) and total system demand forecast (representing system demand and site specific demand) for the DWGM Declared Wholesale Gas Market. A Victorian gas market that allows trading on injections and withdrawals from the Declared Transmission System (DTS). from AEMO's Demand The amount of power consumed at any time Forecasting System (DFS Demand Forecasting System).

This data can be used to validate forecasting methodologies against AEMO's DFS. It is also used to validate AEMO’s demand forecast where there has been a demand override in the scheduling process.

Audience notes

Not every demand generated by the AEMO DFS is used in the scheduling process. Participants should reference INT108 Schedule Run Log to determine the Demand Forecasts used for each schedule.

The INT108 forecast_demand_version identifies the forecast used by AEMO in generating a schedule.

Content notes

This report contains data for:

  • the current gas day

  • 1-day ahead

  • 2 days ahead

  • the previous 7 days

Each report therefore can contain data for up to 10 days.

Each row of the report contains data for one generated nodal forecast.

From 15 April 2024, AEMO has a new weather forecast data provider. The following fields will be NULL:

  • previous_day_min

  • max

  • overnight_min

  • average_wind_speed

  • sunshine
