The publication by AGL Energy of the short note about the transformer incident (and injured worker) at Liddell unit 3 yesterday prompted me to have a quick look, following on from the volatility this week.
Following up to AEMO’s recent Intermittent Generator forum, Marcelle looks at the challenges for wind and solar farms in providing consistently good plant availability information to AEMO and the value of transparency of this data.
Third day in a row we see volatility in NSW (and QLD) … and this afternoon AEMO contracts, and then dispatches, Reserve Trader in NSW
David Leitch & Ben Willacy of ITK Services provide an overview of the wind and solar assets in the NEM that are currently up for sale
Second day in a row the price spikes in the NSW region … higher and longer than yesterday. Low aggregate production from Wind and Large Solar across NSW today was clearly one other factor that contributed.
A quick look at a spike in NSW price this afternoon above $3,000/MWh due to a number of different factors … including a trip of unit 3 at Eraring coal-fired power station.

On 25th November, guest author Allan O’Neil examined the ‘X5 Constraint’. Two weeks of operation have passed, so now Allan reviews some of what’s happened.

Earlier this afternoon we were alerted to a price spike in NSW and QLD that was seemingly caused by a unit trip at one of the larger generators in NSW.
A recent development over in the WEM (paying energy users to consume, when there’s too much solar and wind) highlights the lack of foresight in the NEM … where we’ve implemented a significant reform (yet to start) that will do nothing to address negative prices.
Prompted by an SMS alert this evening, we take a look at the tight supply/demand balance currently forecast for the QLD region on Monday afternoon next week (30th Nov 2020).
Given the great interest in the new ‘X5 constraint’, guest author, Allan O’Neil, has invested some time to pick the new constraint equation to understand (and then explain) what it is, how likely it will be to bind, and who is likely to be affected.
From tomorrow (Fri 20th Nov) market participants in south-western NSW and north-western VIC will need to grapple with yet another transmission constraint seeking to ‘constraint down’ their output when it’s sunny and/or windy. This one is named ‘N^^N_NIL_3’.
Today (Thu 19th Nov 2020) the AEMC published a draft ruling following the AER request for a rule change relating to Semi-Scheduled generators … which itself followed from two COAG Energy Council requests to them
Some brief notes about the impact that South Australia’s ‘Stay at Home’ order might have on demand in the region.
Third day in a row, and at exactly the same time as yesterday (Mon 17th Nov) the dispatch price in QLD spiked through the roof. Here’s a quick first look…
