Improving Transparency and Extending Duration of MT PASA

COAG Decision Regulation Impact Statement – Australian Energy Market Commission

On 20 February 2020, the Australian Energy Market Commission (AEMC) released the final rule determination and final rule titled National Electricity Amendment (Improving Transparency and Extending Duration of MT PASA) Rule 2020.

The final rule improves transparency of the medium-term projected assessment of system adequacy (MT PASA) process, reduces asymmetry of generation availability information in the market, and extends the period in which generation availability is published from two to three years. The AEMC is satisfied that the Rule will, or is likely to, contribute to the achievement of the National Electricity Objective (NEO) and provide benefits for market participants because the Rule is likely to:

  • improve transparency and quality of information in the overall electricity market;
  • promote reliability of the power system;
  • minimise direct and indirect costs; and
  • provide regulatory certainty regarding MT PASA inputs and outputs.

The final determination has been assessed by the Office of Best Practice Regulation as compliant with requirements for a Council of Australian Governments Decision RIS.
