A large collection of articles pertaining to the ongoing ‘Energy Transition’ in any of a number of ways.
Specific sub-categories relate to such things as Coal Closure, and other aspects of the transition.
In Part 3 of this Case Study, we look at the source of the Dispatch Interval Availability forecasts for these units at 17:05 on 27th October 2022 (i.e. Self-Forecast or something else, incl AWEFS/ASEFS).
In Part 2 of this Case Study, we look at those 15 x Semi-Scheduled units highlighted with large deviations (mostly under-performance) at 17:05 on 27th October 2022 in order to understand more.
In Part 1 of this Case Study, we start to look at the large collective under-performance across all Semi-Scheduled units (i.e. Wind and Large Solar) at 17:05 on 27th October 2022. More to come in subsequent parts…
In today’s article (a third snippet from GenInsights Quarterly Update for Q4 2022) we take a look at levels of large ‘Aggregate Raw Off-Target’ (i.e. large collective deviations away from Target), which continue to grow for the Semi-Scheduled category and remind us of that question …
Here on this site, and also in real discussions in the offline world, we have been pondering this question for a number of years. For instance, it was pondered in Theme 13 (‘What’s the future for Participation Categories in the…
Another quick article today – this to record the rare use of coal in the UK on a cold evening with insufficient other supply.
Prompted by the massive loss reported by CLP for its EnergyAustralia business, and plans for major outages for 4 units at Yallourn, we took a quick look using ez2view at outage plans.
Allan O’Neil digs through historic FCAS enablement and utilisation levels to examine whether there is an increasing trend in recent years.
Drawing from GenInsights Quarterly Update for Q4 2022, and the next version of our ez2view software, we take a look at the *current* expectations for closure of Liddell Power Station (within weeks) and Eraring Power Station (in 2025). A segue into this week’s update to the ESOO, perhaps?
Dan Lee provides this write-up of a recent study tour to Timor-Leste and reflects on lessons learned about how the transition is affecting developing nations.
Allan O’Neil provides an explainer about how small deviations in supply and demand are managed in the NEM, in order to help us understand the apparent swings in frequency that we noted in QLD last Friday.
Guest author, Allan O’Neil, takes the release of the GSD2022 as an opportunity to take a look at the past 10 years of performance of the four-unit Liddell Power Station (one unit closed in 2022 and three to close soon in 2023), contrasting against two other black coal-fired stations.
We thought it would be worth linking to Jim Chalmers’ article this week in The Monthly, as it seems these ideas will have (more) implications for the National Electricity Market.
One other thing noticed this morning was the scheduled drop in coal availability in spring 2025 (not just because of Eraring’s scheduled closure).
UQ’s Richard Bean and Neil Horrocks discuss a project they are involved with that would enable network operators to see household voltage and current data in real time.
In light of recent events, Dan Lee does some digging to find historical incidences of islandings and transmission tower failures.
Striving to catch up on a couple weeks away, today I’ve tried to piece together the current state of deliberations about the potential (and rushed) implementation of caps on domestic gas and coal prices feeding into the NEM.
Three other reports released by AEMO on 1st December 2022 will also make for interesting reading.
Today the AEMO released a 101-page engineering framework report on the steps required to operate the NEM at 100% instataneous penetrations of renewables.
A short article, to record the upgrade of the ASEFS and AWEFS forecasts for Semi-Scheduled (i.e. Wind and Large Solar) units.
