After spending a day looking into the future (at prospective generation developments) I noted this reverse correlation between wind and volatility that’s been occurring over the week.
Elevated prices persist this morning in Victoria, South Australia and Tasmania
Prices plunge on the day the Carbon Tax is repealed
Reduced export capability over QNI south contributed to the low prices seen last week.
Have generators already removed the carbon tax from their bids, in July 2014 – and is this the reason why we observed prices plunging on 1st July?
Demand plunges in Queensland during the day – dragging prices down with it.
With the repeal of the carbon tax looking more likely, and July 1st only just around the corner, someone asked today if we could calculate what the spot price might be without carbon.
Hopefully not an omen of what is to come tomorrow night…
Today (Wednesday 24th July) we note how the Queensland lunchtime electricity demand is stuck in the blue zone – the uptake of solar PV, and a sunny day for Clean Energy Week, would be part of the reason.
An animation of 90 minutes this morning where the price gyrated wildly in response to a trip at Yallourn, and numerous subsequent reactions by market participants and the AEMO.
A cold evening in the NEM, and yet demand can’t make it past 30,000MW – which would have been quite startling 4 or 5 years ago (but not now, as demand has been declining for a number of reasons).

Following yesterday’s warnings about the potential for a tight supply/demand balance in South Australia this week, it was not really a surprise when the SMS alerts from NEM-Watch began buzzing for the 07:20 dispatch interval this morning (NEM time), highlighting that the dispatch price in SA had jumped to $12,199.20/MWh. This has continued through the morning.
It’s not looking that great, currently, for the supply/demand balance in South Australia this week – when viewing predispatch, ST PASA and AEMO’s Market Notices
A collection of analysis, observations and commentary about what we see (and have time to comment on) in terms of winter 2013 in Australia’s National Electricity Market
The distinctive winter demand shape returns – and with it comes the evening peaks in prices (even on a Sunday).
A snapshot of an instance of the Queensland regional constraint, which has returned after an absence over the autumn months.
A brief look at the significant increase in output from hydro plant coincident with (and slightly preceding) the introduction of the Carbon Tax
Now that we’re through the first week of Australia’s new Carbon Tax, we thought it would be of interest to have a look at whether there has been any significant…
