In our third guest authored post this week, Blake Ashton from SA Power Networks talks about the SA islanding event that occurred just over twelve months ago – how SAPN managed solar curtailment, and how their new ‘flexible exports’ option can address future challenges.
A quick record of a new ‘lowest ever’ point for Market Demand in NSW on Sunday 8th October 2023
Echoing a question we’ve been asked – about the extent to which rooftop PV has been curtailed as a result of these minimum demand points.
The long weekend provided an opportunity to review 10 years of electricity bills at home to look at net usage patterns and net solar injections from our home rooftop solar system. What have we found, at this point?
UQ’s Richard Bean and Neil Horrocks discuss a project they are involved with that would enable network operators to see household voltage and current data in real time.
A quick look at rooftop solar PV forecasts after ElectraNet’s chief executive warns about overproduction of distributed energy generation later in the week.
A short initial article to note that curtailment of distributed PV is underway in South Australia under processes previously established by the AEMO.
Hot on the heels of a new low point for Operational Demand in South Australia on the weekend, this evening AEMO warns of an ‘elevated risk of contingent disconnection of Distributed PV’ tomorrow (Wed 19th Oct 2022).
Something I’ve not seen all that much for quite a while … zero and negative prices in the middle of the day.
This article – Part A of a 2 part series – reviews how rooftop PV output varied and considers its influence on Queensland demand on the 1st and 2nd of February, 2022.
Out-of-the-blue, the price spikes up near $10,000/MWh in South Australia on an otherwise ‘boring’ day … a sign of what we should expect increasingly in future?
Ben Domensino of Weatherzone discusses an extreme month of wet weather across Australia during November, and its impact on solar generation.
South Australia hits a very low point for ‘Market Demand’ on Sunday 21st November 2021 … all the way down to *actually be below zero!*
A quick look backwards, later in the afternoon, at the new ‘lowest ever’ point reached for demand in the NSW region.
Looks like AEMO will be announcing a new ‘lowest point’ for Operational Demand in NSW later, given what has happened on Monday 4th October 2021 (Labour Day holiday).
In addition to being a low point for Scheduled Demand and Operational Demand in the QLD region, it was also the case on a NEM-wide basis.
Just last Friday the AEMO notified stakeholders more broadly about their new Market Notice Framework about ‘Minimum System Load’ and/or ‘Distributed Photovoltaics (DPV) Contingency’ … prior to Sunday’s new lowest point for minimum demand in South Australia!
Sunny skies and mild weather in South Australia on Sunday 26th September sees a new (lower) point for ‘Minimum Demand set in the South Australian region.
Sunday 15th August saw lowest level of Operational Demand in the NEM for a winter period, NEM-wide. This also led to a number of other outcomes (including higher renewable penetration, negative prices, … and chatter on social media).
A rainy Saturday morning reminds us the price volatility for Q2 in QLD has not totally gone away … with elevated prices for ENERGY and also Contingency FCAS (Raise 6 second and Raise 60 second).
