Reflecting on the transmission tower failures in Victoria in February, a group of researchers from the University of Melbourne have put together this summary of what the long-term wind data is showing, and what it means for the power system.
In this article we’ll have a first pass at what happened in Victoria on Tuesday 13th February 2024 at a DI-by-DI level … which we call ‘Timeline #1’ level – noting will go more granular later (Timeline #2) and less granular later (Timeline #3).
A short walk outside prompts a quick look at Brisbane apparent temperature … equals the high mark set in February 2017
A bout of severe weather for many parts of south-eastern Australia brought challenging weather conditions which appear to have impacted variable renewable energy forecasts for the NEM. The case study delves into forecast differences on the 7th, 8th and 9th of September 2023.
Dan Lee tracks the demand forecasts against the actual outcome in QLD last Friday afternoon. The final result was as much as ∼1,000MW lower than the maximum forecast of demand published by the AEMO, which alludes to the inherent difficulty of electricity market forecasting.
Our fourth article looking forward to this Friday afternoon (3rd February 2023) in the Queensland region, where successive AEMO STPASA forecast data is showing considerable variability about what peak demand might be for the QLD region (it *might*, if predictions turn into reality, smash the prior all-time record). Dan Lee looks into how the demand forecast has been evolving and what to watch for this Friday afternoon.
All’s been quiet in the Australian National Electricity Market … which is not the same as the situation in North America, where extreme cold has stretched supplies across a large swathe of the country and storms have disrupted supply to more than a million people.
Ant Sharwood of Weatherzone provides some insights into the intensity of last weekend’s thunderstorms in South Australia, which had severe impacts on the state’s transmission network.
A weekend of prolific thunderstorms had a significant impact on the NEM. Ben Domensino of Weatherzone reports on the 4.2 million+ lightning strikes that were detected across the country on Saturday and Sunday.
Third article on what happened on Friday 14th October 2022 – sharing a photograph of the damaged transmission (thanks to TasNetworks for the photo, and Zeus for the weather) and outlining a number of different timescales that could be considered with respect to this event.
A news article this morning along the lines of ‘coldest in 100 years’ jumped out at me.
Ben Domensino of Weatherzone examines the recent heavy rainfall and subsequent flooding across much of Australia’s eastern seaboard
Ben Domensino from WeatherZone has provided this summary about what we can expect to see across Australia during the 2021-22 summer weather season.
