Following from the release of GenInsights21, in this article we look at some of what that analytical publication can help us understand, in terms of how the changing market is impacting on the role that renewables will increasingly play in the NEM in the years to come.
solar PV; wind farm output
Only two dispatch intervals (thus far?) of extreme pricing tonight for QLD and NSW (Wed 2nd June 2021). Here’s the first one…
An unfortunately timed significant slump in output across all Wind and Large Solar plant in NSW was another of the factors contributing to the price volatility seen in NSW last week.
Third day in a row we see volatility in NSW (and QLD) … and this afternoon AEMO contracts, and then dispatches, Reserve Trader in NSW
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.
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.
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.
A short review, as it happens, on a day where renewable production reached 10,000MW in aggregate across the NEM.
Ancillary Services Matter! No longer just realm of electrical engineer or energy trading boffins, ancillary services (and particularly Frequency Control Ancillary Services or FCAS which will concentrate on today) have become front and centre in so many ways that barely a day goes by without market observers referring to grid stability, inertia or frequency management.
Laying out the framework for the analysis I’m doing for my presentation at All Energy 2015 – about the role Demand Response might play in a future market dominated by intermittent generation
