A quick look at the situation today, where generation in central and northern Queensland was constrained down in the middle of the day, driving prices higher.
A quick first look at the way the AEMO is currently seeing the supply/demand balance for the Queensland region through summer and Q1 2019 – with the “out of left field” possibility of industrial action making it even more interesting.
The growth of Large Solar in the NEM has been phenomenal, and a sign that things are changing quickly in the Australian energy industry. The chart attached is the maximum…
Some conversations with new generation developers about their prospective developments in northern Queensland has prompted some analysis to help them understand the size of the addressable market for them.
Temperature forecasts are for hot weather in Queensland early this week – which means AEMO is forecasting high demand in the QLD region. With this, they are alerting on a forecast LOR2 Low Reserve Condition warning. We take a look…
The multi-region islanding event on Saturday 25th August was a very rare event – perhaps the only one’s that occurred in the history of the NEM. It has generated plenty of questions – and driven our analysis further. We share some more observations here, and keenly await the draft AEMO report.
Following on from Saturday’s islanding event, we use our current interest in AEMO’s 4-second SCADA data to prove a little more…
Both the QNI and the Heywood interconnectors tripped around the same time on Saturday 25th August 2018 (not apparent at this time which one was first, and why), leading to both QLD and SA regions being separately islanded from the rest of the mainland NEM. This also contributed to over 1,000MW of load shedding in NSW and VIC, and presumably some frequency excursions in QLD and SA.
Returning to the theme of analysis of Q2 prices (completed in 2017 and 2016 due to Q2 historically being an uneventful period) we see that prices have backed off from the “off the charts” level of 2017, but are still much higher in all regions than most other regions. In some cases results are second worst in 20 years.
Some further thoughts on what we’ve termed a “Solar Correlation Penalty” which point-view of some specific dispatch intervals seems to suggest is occurring
A comment made by TransGrid at the Energy Networks 2018 conference today jolted me to update my (somewhat) outdated paradigm of declining demand.
Already we are seeing the highly correlated output of solar PV deliver interesting challenges for the NEM – both to the project proponents themselves, and also to the “everything else” that supplies what’s left of the underlying demand from electricity from any source.
A new peak Scheduled Demand and Operational Demand in Queensland today with Scheduled Demand still over 9,100 MW after 8 PM.
Queensland experienced a new record for Scheduled Demand for electricity today – but what’s particular staggering is how late in the day it happened!
Looks like being an interesting day on Wednesday next week (14th February 2018) with high temperatures currently forecast for parts of both QLD and NSW
Electricity demand in Queensland today reached 9072MW in the 16:40 dispatch interval, passing 9,000MW for the first time this summer.
A quick review of a hot and sticky day in Queensland that saw high levels of demand reached on a Saturday – with demand peaks tomorrow forecast to be just as high (on a Sunday!). Today saw the first major price spikes in the Queensland region of summer.
Queensland demand ramped up, after the sun had gone down Thursday evening, to pass 8000MW for the first time this summer
With Genex releasing an ASX announcement of first revenue at Kidston Solar Farm, we use NEMreview v7 to have a quick look.
Here’s a chronological record of key aspects of government involvement in the generation sector within Queensland.
