Keeping Up with the Curtailment Part 2: The what and the where
Dan Lee takes a deeper dive into network and economic curtailment, and shares some charts and data maps that demonstrate seasonal effects, and the geographic spread of units affected.
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.

Enroute to Melbourne today for the EUAA National Conference starting tomorrow, I grabbed some flight time to have a quick read through the Grattan Institute’s latest offering – a 45-page report appropriately titled ‘Keeping the Lights on’: Quite topical that…
Given that we’ve taken an interest in what’s going to happen with the looming closure of Eraring Power Station, I thought it would be useful to our readers to highlight Peter Hannam’s article in the Guardian today about a (possibly soon) decision about an extension to service.
A short article this morning to note about a Working Paper from CAEEPR that touches on important (and not well understood?) aspects of this energy transition, as it relates to Firming Capacity requirements.
Yallourn unit 1 has just come offline for its Major Planned ‘performance improvement’ outage – but coincident with that, Yallourn unit 3 is suffering from a run of forced outages.
A short article to mark the start of the long planned outage for Yallourn unit 1, which is aimed (at least in part) at improving the performance of the unit following 2022.
Almost 2.5 years since we released GenInsights21, today we’re publishing this article that contains a precis of the analysis included as Appendix 27 under the title ‘Exploring Wind Diversity’.
Reflecting on the transmission tower failures in Victoria in February, a group of researchers from the University of Melbourne have put together this summary of what the long-term wind data is showing, and what it means for the power system.
It’s Monday 8th April, the two Eraring units that tripped last week are back online – and I wonder what the cause of the coincident trip was?
With GenInsights Quarterly Update for 2023 Q4 completed, and some time till the end of 2024 Q1, we’ve looked back at Tuesday 14th November 2023 (when AEMO had concerns about low System Strength in NSW) and looked at the level of inertia actually seen in the grid. A useful Case Study to say ‘what would have happened without Eraring?’
Prompted by the other article today, I’ve taken a look at published information about the required operations of the Victoria Big Battery (VBB) under the System Integrity Protection System (SIPS).
Last week I was notified of the release of a new ESIG report ‘New Resource Adequacy Criteria for the Energy Transition’, which will be of interest to some WattClarity readers.
A client question (for GenInsights Quarterly Updates) recently prompted a quick look at the delay to the start of the planned outage for Yallourn Unit 1.
Worth noting these three recent news articles from the past 8 days, all pertaining to the slated closure of the Eraring Power Station as early as 19th August 2025 (under 18 months away), but reporting different perspectives.
A 2nd short article falling out of GenInsights Quarterly Updates for 2023 Q4. This one looks at Sunday 12th November 2023 and shows the lowest point in 2023 for NEM-wide Aggregate Scheduled Target (and the largest ramp in Q4).
A short article looking at Friday 8th December 2023 looking at NEM-wide Aggregate Scheduled Target on the day.
A quick look into performance of Genex’ four DUIDs over 2023, as news broke this morning of a takeover bid from the Japanese-based J-Power.
Last article (on the day) about Thu 29th Feb 2024. Prompted by an AFR article just over 24 hours ago, how large was the contribution of Eraring Power Station to the NSW electricity region today?
Some interesting data coming from our forecast convergence widget yesterday afternoon, hinted to us that bushfire smoke is likely to have been impacting rooftop PV generation levels in Victoria.
Tristan Edis of Green Energy Markets argues how system longevity, battery-coupling, distribution network capability, and increasing capacity will shore up rooftop PV’s position in the market.
