Yesterday (Wed 18th Oct 2023) Origin Energy held its Annual General Meeting, with discussion wide-ranging. Here’s two things that jumped out to me about the Eraring Power Station, which is currently slated to close in 2025.
A quick article on WattClarity pointing to some research completed by Shukla Poddar and others about what future solar profile might be across Australia, in a climate changed world.
AER announced today (and CS Energy confirmed) that a fine had been issued, and paid, for ‘allegedly operating a generating system without regulatory approval’ – with respect to the Callide C units on 24th May 2021 (i.e. the day before the explosion – but I believe unrelated to the explosion).
The results of the recent MTPASA (Medium-Term Projected Assessment of System Adequacy), published on 17 October 2023, led a declaration of low reserve conditions in Market Notice 110284.
A short note to echo EnergyAustralia’s warnings (reported in the Australian) about possible coal supply issues for Mt Piper power station.
Seeing another reference to ‘Bouldercombe BESS only offline for a day’ on social media prompts this article, to prevent further misconceptions…
The new 1-second FCAS markets have been operational since the 9th October. We take a look to find out how it has fared.
Because we’ll be referring back to it in future, we’ve lifted out Figure 8 from the MASS version 8 (p36/39) and included it here in this belated (and back-dated) article
A quick record of a new ‘lowest ever’ point for Market Demand in NSW on Sunday 8th October 2023
A short note about the publication of a richer MT PASA DUID Availability data set in ez2view v9.8 – made possible as a result of the other change that goes live in the NEM on Monday 9th October 2023
Very Fast FCAS, because it operates at a faster timescale, can arrest the rise or fall in frequency more rapidly than the current fast service and therefore provides an avenue to mitigate the costs of needing to procure increasing levels of the existing fast service. The markets (raise and lower) are going live on 9 October 2023.
Today the Australian Energy Regulator released its annual ‘State of the Energy Market’ report that highlighted rising retail prices and a higher concentration of flexible generation asset ownership.
Echoing a question we’ve been asked – about the extent to which rooftop PV has been curtailed as a result of these minimum demand points.
Looking back at yesterday (Sun 1st Oct 2023) it appears to also have seen a lowest point for NEM-wide demand by both measures … lower than the low point set ~2 weeks prior.
Also noteworthy on Sunday 1st October 2023 was a lower point for ‘minimum demand’ seen in South Australia … with ‘Market Demand’ down to -37MW and ‘Operational Demand’ down to 5MW (just above 0MW)
Sunday 1st October 2023 and the ‘minimum demand’ point for the QLD region (measured by ‘Market Demand’) has fallen lower still on a sunny spring long weekend.
On Friday 29th September 2023 we look back at Kogan Creek via ‘Bids & Offers’ in ez2view over 20 days to see what’s visible, in terms of any impact of the current Industrial Action
A short article Thursday evening 28th September 2023 with the battery back online and charging, after the fire.
A quick article, following a social media update by CS Energy on the repair process for the cooling towers at Callide C.
Yesterday (Tue 26th Sept 2023) we saw Kogan Creek drop offline for a few hours – and were asked if this was related to industrial action. Here, with the benefit of ‘next day public’ data, we take a first look.
