In May 2022, the AEMC made a final determination to amend the NER provisions relating to the ST PASA to introduce greater flexibility to ST PASA, revise some ST PASA definitions and obligations and require the commencement of the new ST PASA from 31 July 2025.
The final rule “Updating Short Term PASA” introduced a principles-based approach for AEMO to administer ST PASA, included an obligation to publish a ST PASA Procedure, made changes to ST PASA publication timetable, the definition of ‘energy constraint’ and PASA availability.
We’re approaching the end of May 2026, which means we’re almost 10 months since the 31st July 2025 go-live date for unit-level data (and other changes) in ST PASA. … our ez2view software was upgraded to v9.12 in June 2025 in anticipation of those changes,...
New unit-level availability data and other changes to the STPASA process are scheduled to go live from today.
Worth a short note today (Friday 27th June 2025) to note the publication of MN127877 – which references two market changes that will improve market transparency for all types of participants
Belatedly noting the AEMO's publication of the Industry Go Live Plan for the ERI and ST PASA changes.
