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).
Looking back at Tuesday 13th April 2021 – a day in which the ex-tropical cyclone Seroja in Western Australia caused some wobbles in rooftop solar PV output in South Australia.
Three price spikes in the QLD region on Saturday 10th April 2021 help to remind us that how increasingly dependent we are on various machinations of the weather (including, on these occasions, cloud cover and solar output).
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).
Records continue to tumble in the off-season, with the rise of rooftop PV. Both South Australia and Whole-of-NEM hit new low points Sun 11th October 2020.
A month on from the prior low point seen for Scheduled Demand (and Operational Demand) across Queensland in the middle of the day, the low point mark is driven lower still on Sunday 27th September 2020.
Hot on the heels of a new record low point for Scheduled Demand (a week ago) in VIC, today sees Scheduled Demand in SA plunge to 315MW in the 11:50 dispatch interval on Sunday 13th September 2020.
Some quick reflections on a day that saw spot prices in QLD down below $0/MWh for most of the period seeing strong daylight hours, hence strong injections from rooftop PV systems.
Analysis compiled to explore what the impact was of the unusual weather pattern (extensive cloud cover and cold temperatures) seen across a large part of Queensland on Saturday 23rd May 2020.
… because the evidence currently suggests that this is just not the case (in this article I explore and explain further)
