As a short PS to last Thursday’s note about the shaky state of Tassie electricity supplies, and prior to the EUAA 1/2 day session in Hobart next Tuesday (will look forward to seeing you there, if you are going), here’s a quick PS to highlight how the diesel gensets have started to appear in the AEMO data set – and hence are being fed through to NEM-Watch and our other products, as highlighted in the snapshot from today:
However for general industry “hobby” observers, we have provided the RenewEconomy-sponsored NEM-Watch widget as a free (and freely embeddable) version to keep an eye on how the generation mix will change in the coming weeks and months.
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.
We follow on from A 292MW drop in “Market Demand” in Tasmania, on Saturday 16th August 2025 enlisting this “Part 2” to understand the sequence of events using 4-second data.
This week saw very low average prices across the NEM (below $21/MWh average across the week in all mainland regions).
Except for 2 half-hours in Tasmania on Tuesday 7th February (when the price rose to just over $1,000/MWh), prices in Tasmania remained at and around $30/MWh for the whole week.
