What’s the market data saying about this Summer?
Guest author, Allan O’Neil, follows up a post in September (reviewing what the AEMO’s ESOO was saying about summer 2017-18) with this review of updated data

Possibilities of Peak Demand (VIC and SA) during summer 2017-18

Here’s two odd examples being used in attempt to justify a claim of why privatisation will lead to higher spot prices
Reading an article in the Courier Mail on Saturday I was struck by the use of two particularly odd examples to support a case for retention of government ownership of electricity generation.
September Update: More Regulation on the Retail Side
Following from my August update, here’s two developments we have seen in relation to retail & networks regulation.
Initial questions about the LGC market
Our first look at trended LGC production (aggregated by state/territory) and LGC spot prices (monthly average), now possible in NEMreview v7, generates a number of questions…
How much wind-powered electricity production has been curtailed in SA since these new constraints were invoked?
An article that sums up some decidedly un-quick calculations we’ve performed – looking over an 8 week period to 13th September to estimate how much wind power has been curtailed by the AEMO.
How significant would it be, if Mt Piper were forced to close (at least temporarily)?
A quick look at the scale of the challenge, if Mt Piper were to be forced to close following a court challenge to coal supplies upstream
Decoding AEMO’s latest ESOO–will the lights stay on this summer?
Some initial analysis by our guest author, Allan O’Neil, about what AEMO’s Statement of Opportunities 2017 is saying in terms of this coming summer 2017-18
On Saturday 2nd September, AEMO reacted to Severe Weather Warning by imposing limits on interconnector
On Saturday 2nd September, AEMO responded to a BOM-issued “Severe Weather Event” warning by reducing flow capacity west on the Heywood link. Here’s how that looked…
Wind production in South Australia roared out of the June doldrums to a new production record in July 2017
From one extreme (perhaps lowest ever in June 2017, on like-for-like) to the other (new record production) in the space of just one month for aggregate wind in South Australia
August Update: Regulatory Responses to Pricing Concern
Some thoughts from guest author, Connor James, about “what’s next” in response to energy user concerns about high and escalating prices.
Cloud patterns on Friday 19th May 2017 – leading to a day of low Solar PV output, NEM-wide
Following Wednesday’s article by Paul McArdle on WattClarity, we’ve reviewed the (very cloudy) weather patterns for Friday 19th May 2017, and the accuracy of Solcast’s predictions of a day of low solar PV output
Wind Farm output in SA constrained, again, by AEMO’s “System Strength” constraint
A quick note about high wind speeds in South Australia this afternoon leading to AEMO constraining wind farm output down for System Strength reasons.
Energy prices below zero in South Australia, but Raise Regulation FCAS prices through the roof
Low energy prices in South Australia combined with high prices for Raise Regulation
The Southern Annular Mode (SAM) contributes to recent wind drought
An explanation of how the Southern Annular Mode (SAM) contributed to the wind drought we observed recently on WattClarity.
If spot price outcomes through Q2 2016 were “truly remarkable” then price outcomes for Q2 2017 were off the chart
A year on from my review of “remarkable” prices seen in Q2 2016, I return to the same analysis and update for Q2 2017. Outcomes are even more extreme…
Where’s the wind gone? NEM-wide wind farm operation lowest in 5 years (maybe ever, on like-for-like basis?)
A brief look, in the time available today, at a truly remarkable low point in aggregate wind farm output across the NEM through June 2017
Another industrial energy user enters Liquidation (in South Australia this time)
Coming back from a week out of the office, I was disconcerted to see that yet another industrial energy user has closed its doors.
