Allan O’Neil provides an explainer about how small deviations in supply and demand are managed in the NEM, in order to help us understand the apparent swings in frequency that we noted in QLD last Friday.
Ben Willacy of ITK Services examines the GSD2020 and seeks to highlight what the report can tell us about supply side price drivers in the NEM
David Leitch & Ben Willacy of ITK Services provide an overview of the wind and solar assets in the NEM that are currently up for sale
Some quick notes today, to document high-level data (to be explored later) relating to some significantly depressed solar harvest data today due to the widespread cloud/wind event.
Tom Geiser, Senior Market Manager at Neoen, discusses the merits of proportional, relative control on the issue of small solar curtailment.
Guest Author, Warwick Forster, looks at designing a combined solar & storage business model for the NEM
The growth of Large Solar in the NEM has been phenomenal, and a sign that things are changing quickly in the Australian energy industry. The chart attached is the maximum output of each region from Large Solar installations on a…
Recently there have been a number of media reports of energy industry people talking about too much solar. One of our guest authors takes a look.
New South Wales recently experienced a severe heatwave, which saw parts of the state exceed 45°C. During this three day period, small solar PV (i.e. PV systems that are not registered as generators in the NEM), generated about 17 GWh of power.
NSW demand rose to a near-record high on Friday the 10th of February, and QLD soared to a new record demand on that Sunday, amidst an intense heatwave. While this heat-stressed our electricity markets and infrastructure, the nation’s rooftop solar PV systems were providing critical load reduction under plentiful sunshine.
GSES recently gave a presentation at the APVI workshop in Brisbane as part of the International Battery Association conference.
The content of the presentation would be of interest to WattClarity readers, hence this guest post – which focuses on three possible future business models, that would mean very different outcomes to the incumbents that have become accustomed to “business as usual” over many years.
A cold evening in the NEM, and yet demand can’t make it past 30,000MW – which would have been quite startling 4 or 5 years ago (but not now, as demand has been declining for a number of reasons).
