As noted 7 days ago (Tue 5th July), I’ve just returned from over a month away (and disconnected from the NEM), and have been striving to catch up.
One of the things I think everyone in our team missed – and you might have as well – is that the AEMO’s been working through Primary Frequency Response (PFR) Test Guidelines for Semi-Scheduled Plant:
Paul was one of the founders of Global-Roam in February 2000. He is currently the CEO of the company and the principal author of WattClarity. Writing for WattClarity has become a natural extension of his work in understanding the electricity market, enabling him to lead the team in developing better software for clients.
Before co-founding the company, Paul worked as a Mechanical Engineer for the Queensland Electricity Commission in the early 1990s. He also gained international experience in Japan, the United States, Canada, the UK, and Argentina as part of his ES Cornwall Memorial Scholarship.
The AEMO began publishing actual intermittent generators (SCADA) availability data:
(a) to the EMMS Data Model in the Production environment from August 13th 2024 and
(b) to NEMWeb from August 14th 2024.
This 18th Case Study in the series investigates two separate dispatch intervals showing extreme collective under-performance across all Semi-Scheduled units on Monday 25th March 2019.
Today (Tue 23rd May) is the go-live date for AEMO’s EMMS v5.2 – which will contain new data for some market enhancements. Here’s a quick look at where this first change will appear in ez2view, highlighting some considerations for Semi-Scheduled units and self-forecasting.

Hi Paul, you have probably got this a hundred times already, but in case it was missed; in the headline you have Fri 13th instead of Wed 13th. Spooky.
oops!
