I’ve been focused elsewhere the past day or more – but wanted to wrap up Friday with a short note to say that our ez2view alerts notified me that Tamar Valley CCGT in Tasmania finally came offline on Thursday morning 20th August 2026 (after an operational period of more than 30 days).
Here’s a snapshot of the most recent 7 days of operation, and the current expectation for availability out 7 days, in the ‘Bids & Offers’ widget in ez2view – as at 15:05 NEM time on Friday 21st August 2026:
Note that the MaxAvail in PD/ST PASA suggests that the unit may be online again from Sunday 23rd August 2026.

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.
Whilst we’re speaking about events on Saturday 15th August 2026, worth also noting that today marks over one month of ongoing production from the Tamar Valley combined cycle plant in Tasmania.
This is a very sensible use of gas if you have to use it. Running a CCGT at constant load for 30 days probably uses about half as much gas per MWh as ramping an OCGT to follow load wher it almost never runs at optimum efficiency
