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.
This morning I was fortunate to listen into an ESIG Webinar with respect to their report ‘Weather Dataset Needs for Planning and Analyzing Modern Power Systems’
Tristan Edis from Green Energy Trading discusses whether a surge in renewable energy projects and battery capacity would be sufficient to fill any reliability gap before (and after) Eraring’s scheduled closure.
Guest author, Allan O’Neil, takes a detailed look at how VIC1-NSW1 transfer capability has been limited frequently due to constraints related to the 051 line in southern NSW, and what it means in terms of inter-regional settlements residue accumulations, market efficiency overall, and the energy transition.
The first part of a Case Study looking at a large 5-minute ramp in ‘Aggregate Scheduled Target’ in the middle of the day (an unusual time) on Friday 8th September 2023
The Media Release from the NSW Department of Energy on 22nd November 2023 noting 1,075MW of new firming capacity in NSW – targeting operational date of December 2025.
We’re seeing an increasing number of claims on social media along the lines of ‘South Australia exporting more than it imports’. Whilst that was true around 2019, it’s NOT been the case for a number of years.
A brief article as a first Case Study looking at Friday 18th August 2023, in conjunction with the compilation of GenInsights Quarterly Updates for 2023 Q3.
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.
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.
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.
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.
A quick note about Eraring Power Station, with the NSW state budget released today (Tue 19th Sept 2023).
Dan Lee looks into utility-scale storage in Queensland – including the need for megawatt-hours, the state of the build-out, and the current market price signal for duration.
In his second article about the 2023 ESOO, guest author Allan O’Neil takes a look at what the AEMO has published with respect to various options for firming capacity to increase the reliability of aggregate supply to below the two thresholds (the Reliability Standard and the Interim Reliability Standard)
Yesterday, the NSW Government released both the Marsden Jacobs report (NSW Electricity Supply and Reliability Check Up) and the Government’s Response.
The 2023 ESOO contains some some reporting (and data) about one particular contingency plan … delaying retirement of existing thermal generators (with Eraring a case in point).
In this article we delve in deeper on Thu 30th Jan and Fri 31st Jan 2020 … two days that saw extreme levels of ‘Aggregate Scheduled Target’ (i.e. AggSchedTarget – a requirement for firming capacity). A timely review, given two developments arriving tomorrow (on Thursday 31st August 2023).
Third article today looking back at news with respect to ‘coal closure’ … this article pertaining to EnergyAustralia’s Mt Piper station in NSW.
Also in the past week, news media (claiming to have sighted some of the ‘Electricity Supply and Reliability Check Up’ from MJA with respect to Eraring Power Station) report the potential extension of service.
