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'...
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...
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.

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A comment made by TransGrid at the Energy Networks 2018 conference today jolted me to update my (somewhat) outdated paradigm of declining demand.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...
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...
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...
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.
