Coal generation gets a run in the UK to ensure supply meets demand
Another quick article today – this to record the rare use of coal in the UK on a cold evening with insufficient other supply.
Energy Transition
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.
A quick look at EnergyAustralia’s outage plans for Yallourn Power Station
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.
Has adding wind and solar upped the need for FCAS in the NEM?
Allan O’Neil digs through historic FCAS enablement and utilisation levels to examine whether there is an increasing trend in recent years.
Current expectation for closure dates of Liddell and Eraring Power Stations
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?
Darwin to Dili: The contrasting challenges in Timor-Leste during an energy transition
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.
Investigating last Friday’s frequent frequency swings
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.
Farewell Liddell
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.
What does ‘Rethinking Capitalism’ mean, for the National Electricity Market?
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.
Coal crunch within sight, with Eraring scheduled closure in 19th August 2025
One other thing noticed this morning was the scheduled drop in coal availability in spring 2025 (not just because of Eraring’s scheduled closure).
How closely monitoring households’ energy data can unleash their solar outputs and (possibly) make them more money
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.
How common are islandings and transmission tower failures in the NEM?
In light of recent events, Dan Lee does some digging to find historical incidences of islandings and transmission tower failures.
Price Caps to be implemented on Gas and Coal (perhaps?) … with impacts to be felt in the NEM
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.
AEMO reports on (and webinar about) System Strength, Inertia and NSCAS
Three other reports released by AEMO on 1st December 2022 will also make for interesting reading.
AEMO releases ‘Engineering Roadmap to 100% Renewables’ report
Today the AEMO released a 101-page engineering framework report on the steps required to operate the NEM at 100% instataneous penetrations of renewables.
Enhancement of ASEFS and AWEFS forecasts provided by AEMO – from Wednesday 23th November 2022
A short article, to record the upgrade of the ASEFS and AWEFS forecasts for Semi-Scheduled (i.e. Wind and Large Solar) units.
ESB releases Directions Paper with respect to Transmission Access Reform
Also today (Thursday 10th November 2022) the ESB has released a Directions Paper on Transmission Access Reform – including suggestions for both Investment Timeframe and Operational Timeframe.
Origin Energy (perhaps) to be acquired and broken apart?
A short article about Origin Energy’s announcement today.
Analysis Paralysis – where has our engineering gone?
Kate Summers gave this speech about the ‘paralysis by analysis’ currently occurring in the energy industry at Melbourne’s All-Energy Australia Conference on Wednesday 26th of October.
Back to the future
Greg Thorpe of Oakley Greenwood discusses some of the latest developments in the electricity sector which could be described as ‘back to the future’.. and provides a forecast of what might follow.
Griffith University study ‘Quantifying the risk of renewable energy droughts’
The Griffith University (by Joel Gilmore, Tim Nelson and Tahlia Nolan) study mentioned in earlier RenewEconomy article is now accessible on the Griffith University website here.
