Jonathon Dyson of Greenview Strategic Consulting uses the Generator Statistical Digest to highlight FCAS revenue results, contingency recovery and regulation costs for 2019, and help explain why it is critical for us all to understand FCAS.Read More
Guest author, Allan O’Neil, takes a look at what’s happened in the (islanded) market for FCAS services in South Australia over the past two weeks with Heywood out of service. He notes:
“generators in SA as a group would have paid out roughly twice in contingency raise FCAS costs what they earned from selling energy”
Summer 2019-20 is not yet done, but already we have seen some extremes in temperature in different places – which have led to different concerns. Today I use the GRC2018 and GSD2019 to take a look at what the implications for this actually are.
Rooftop Solar PV systems did trip in SA on Friday 31st January 2020 in conjunction with the Heywood trip
Investing some time over the weekend with a some higher-speed data on output of rooftop solar PV systems across VIC and SA reveals some interesting observations about what happened on Friday 31st January 2020 in conjunction with the transmission damage and Heywood trip.
Guest author, Allan O’Neil delves further into understanding what happened in response to the transmission tower failures on 31st January 2020 that sent system frequency in South Australia and led to a large reversal of flows.
It feels like a lifetime ago, already, but I do vaguely remember that we released our Generator Statistical Digest 2019 last week, on Tuesday 28th January 2020. All the tasks…
Cautioning readers that I am a novice at reading frequency data in this manner, I take a first look at how the frequency in Melbourne and South Australia varied at the time of the transmission outage at 13:24:30 on Friday 31st January 2020.
13 headline questions and observations following the long-term islanding, starting Friday 31st January 2020
In order to help us (internally) map out all the different threads to explore in terms of what happened on Friday 31st January 2020 on a remarkable day in the NEM, I’ve identified a few of the key threads here over the weekend. More articles to follow as time permits….
With the benefit of more data available today, can piece together why there was the sudden drop into LOR2 territory on Saturday 1st February 2020 (something that alarmed me, and resulted in AEMO directing a participant to make capacity – just withdrawn – available again).
I’ve snuck into the office on Saturday to start the process of piecing together some of of the different aspects of what happened yesterday to follow on from Friday evening’s…
Today (Fri 31 January 2020) saw NEM-wide demand reach levels never seen before (excepting 29th January 2009). This was just the start of the white knuckle ride.
Guest author, Allan O’Neil does a masterful job with limited time in reviewing some of the goings-on in the NEM (particularly VIC and SA) on Thursday 30th January 2020
Published at 12:02, this is a view looking forward to the expected (very high) peak in electricity demand across the NEM this evening.
A brief overview of a stressful afternoon/evening in the NEM, where a confluence of events (heatwave-driven high demand, low wind, coal unit trip, etc…) drive LOR2 low reserve condition notice in both VIC and SA, and gear AEMO up to call on Reserve Trader (yet again!)
A quick look (ahead of time) at what looks set to be a very high level of electricity demand right across the NEM tomorrow evening, Friday 31st January 2020. Just in time for the Australian Open semi-finals.
Comments by the Brett Redman (CEO of AGL Energy) about the poor performance of Liddell Power Station, as reported in the media, prompted me to open up the Generator Statistical Digest 2019 to have a quick look.
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…
We’ve been appreciating the early orders flowing in from those who did not wait until the release of the GSD2019, and we’re pleased to announce that this new Statistical Digest is available today.
Jonathon Dyson, Director of Greenview Strategic Consulting and co-developer of the Generator Statistical Digest 2019, uses insights from the GSD to illustrate the nuances of generation in the NEM as it goes through a major transition.
Guest author, David Leitch, in his first article here on WattClarity, walks through some of what first jumps out to him in his initial review of the Generator Statistical Digest 2019.
