Worth a short note with this snapshot from the ‘Bids & Offers’ widget from ez2view at 19:00 (NEM time) on Thursday 12th June 2025 to highlight the short-lived return to service at YWPS4:
We can see that the unit:
1) Came back online yesterday evening (Wednesday 11th June 2025) at around 22:00 … thereby missing out on the revenue opportunities that evening; and also
2) The unit came offline today around 15:30 … so also missing the ‘higher and longer’ period of volatility this evening.
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.
An initial review of some (wholesale) supply-side factors contributing to the extreme price volatility (and Reserve Trader etc) that occurred in the first week of February 2022 in the QLD region of the NEM.
A brief overview of a stressful afternoon/evening in the NEM, where a confluence of events (heatwave-driven high demand, low wind, coal unit trip, etc…) drive LOR2 low reserve condition notice in both VIC and SA, and gear AEMO up to call on Reserve Trader (yet again!)
Following some questions yesterday (from clients and others) we take a quick look at how Yallourn Power Station is progressing in coming back from outage caused by inundation from the nearby river.
