Guest author, Allan O'Neil, invests some time to explore a number of different aspects of Easter Saturday (11th April 2020), each noteworthy in their own right (including low demand, high percentage share renewables, negative prices and dynamic bidding)
Guest author, Allan O'Neil tries to piece together further detail of what is intended with the apparent tightening of the Reliability Standard (which has sat at 0.002% USE for many years).
Using the (hot off the press) Generator Statistical Digest 2019, we take a look across all 304 DUIDs to see how they performed through calendar 2019 in terms of large excesses in 'Raw Off-Target' in both directions. These results suggests implications for the future...
Two earlier articles today prompt this follow-on piece, specifically focusing on what's being requested by ERM Power in two separate rule change requests relating to the MT PASA process.
Another weekend reviewing progress on the Generator Statistical Digest 2019 (nearing completion) and I thought it would be of interest to share some insights about Loy Yang A unit 1 that jump of the sample page provided to us in yesterday's draft.
Guest author, Tristan Edis, looks particularly at the Queensland Region of the NEM, and an almost complete stop in the development of new renewables projects.
A quick look at what would have been a new "lowest ever" point for SA Scheduled Demand today at 12;30 ... if the AEMO forecast had held to be valid.
Guest author (and power system control specialist), Kate Summers, looks at what's changed since she published a paper on frequency control in the NEM back in January 2017.
An email alert from NEMwatch (noting Scheduled Demand under 500MW in South Australia today) distracts us, and prompts us to dig a little deeper at the longer-term trend.
Our various dashboard views of the NEM (NEMwatch, ez2view and deSide) have been showing what's seemed like increasing numbers of zero and negative prices in the NEM recently - particularly in QLD. Coupled with this we've seen various commentary on social media. Hence we took...
AEMO releases its Electricity Statement of Opportunities today, with an initial flurry of press coverage. Another reminder of heightened risk that the NEM is increasingly facing...
Last week the AEMO released a draft of the Marginal Loss Factors (MLFs) that would apply to both generation and loads connected to the NEM. This page on the AEMO site links to more details. On that page, the AEMO notes: “The NEM is transforming,...
AGL released its investor presentation yesterday - several people flagged the availability stats within the presentation (they knew we were looking at aspects of reliability for our Generator Report Card 2018). Hence I take a brief detour and have a quick look.
Guest author, Tristan Edis, takes a look at the changing pattern of generation by fuel type in 2018
A comment made by TransGrid at the Energy Networks 2018 conference today jolted me to update my (somewhat) outdated paradigm of declining demand.
Here's a chronological record of key aspects of government involvement in the generation sector within Queensland.
The wholesale cost of electricity has risen (too fast, too high) in recent years. However let's not let ourselves be conned into believing that this has arisen, now, because of the creation of the NEM back in 1998.
The National Electricity Market (NEM) is designed to operate at 50 Hz. Frequency deviation occurs when generation and load are mismatched. It is important in a lightly meshed and long network such as the NEM to maintain tight frequency control and that frequency response is...
When markets operate normally, a sharp rise in the price of any commodity triggers a boom in exploration, development and new supply. But this is not seeming to happen in response to high domestic gas prices. In this article, guest author (Graeme Bethune) examines why.
A quick look at first output of Barcaldine Solar Farm - as a segue into consideration of what we see as an "audacious" 50% by 2030 ambition.
