ACIL Allen Consulting has supported us in the design of a forecasting approach for wholesale and environmental costs and provided an expert report on approaches for a retail allowance.
The report Default Market Offer: Wholesale energy and environmental costs estimates for DMO 6 final determination by ACIL Allen Consulting was published alongside the final determination.
The report Default Market Offer: Methodologies for estimating the retail allowance and estimated values by ACIL Allen Consulting was published alongside the final determination.
We have published a spreadsheet of ACIL Allen’s modelling data for the cost of energy for interested stakeholders to understand its forecasts. The information contained in the modelling data is also set out in the ACIL Allen report for our final determination.
Because the treatment of solar exports within the forecasting approach to determine wholesale costs was a key topic raised by stakeholders in submissions to the draft determination, we sought additional advice from ACIL Allen Consulting and Frontier Economics.
The notes provided by ACIL Allen Consulting (dated 21 May 2024) and Frontier Economics (dated 21 May 2024) outline their views on how solar exports should be treated within the forecasting approach to determine wholesale costs. These were published alongside the final determination.
