From Monday 1st Feb 2021 the (720-page) Generator Statistical Digest 2020 is more broadly available – here’s some of what’s in it, and how you can access. Those dozens of clients who had submitted earlier pre-orders were provided early access on Friday 29th Jan 2021.
A chart we threw together quickly at Beer O’Clock today (from the imminent release of the GSD2020) was worth sharing more broadly on WattClarity today…
Quite a synergistic coincidence today that, at the same time as we are finalizing the release of the GSD2020, we see the AEMO publishes its Quarterly Energy Dynamics for Q4 2020.
Several conversations this week prompted me to update the long-term view of how spot prices have trended over time (in particular because average prices in 2020 were quite different than recent years).
Short article today observing higher Scheduled Demand in VIC – which appears to be in large part due to state-wide suppression of solar PV production with heavy cloud and rainfall.
A week ago (Thursday 21st Jan 2021) we received an email from AEMO following the publication of Draft Guidelines for the Wholesale Demand Response Mechanism. We share some thoughts here today.
Forecasts was that it would be hot across Victoria, and demand would be high, through Monday 25th January 2021. But the cool change arrived early.
Second article today, focusing on what happened late in the afternoon and into the evening in South Australia.
It was forecast it would be a hot day in the southern part of the NEM and it did not disappoint. The hot weather was one of the factors that contributed to price spikes … in Regulation FCAS, and then in QLD and later in South Australia.
Following several different warnings of high temperatures forecast for the lead-in to Tuesday 26th January 2021 (whatever you want to call that day) I’ve taken a quick look at what it’s currently forecast to mean for the NEM…
Wednesday 13th January 2021 was a busy day in the NEM, with a couple of different events occurring. In this article we explore a sudden and unexpected drop in output across both rooftop PV and large-scale solar in South Australia that delivered both price spikes, and also broader questions about emerging challenges for the grid (and market).
Today (Wed 13th Jan 2021) a high temperature alert published by AEMO for the Dalby area in southern QLD prompted a quick look at what the GSD2020 shows, in terms of high-temperature limitations of plant around the Dalby area.
A pretty rare event in the NEM, when two units trip simultaneously … so a short article on WattClarity as a result.
Following a presentation to the EESA in September, Dr Robert May and Ashley Nicholls from SA Water have written a case study detailing the sophisticated energy management system that they have developed over the past 7 years.
In the same week that the Energy Security Board publishes it’s ‘The Health of the NEM’ reports, looking from a top-down systems perspective, we crank the handle to produce the ‘Generator Statistical Digest 2020’ as a bottom-up 10-year review of the performance of all Scheduled, Semi-Scheduled and some Non-Scheduled generators and scheduled loads across the NEM that operated through some part of 2020.
Using an in-development (but soon to be released) widget in ez2view we take a look at forecast availability for coal units in NSW, VIC and QLD for the critical, and normally volatile, Q1 period 2021.
