Electricity demand stopped declining after 2014 (on a NEM-wide, Annual Average basis)
A comment made by TransGrid at the Energy Networks 2018 conference today jolted me to update my (somewhat) outdated paradigm of declining demand.

Yesterday (Thu 24th May) AEMO issued a Low Reserve Condition notice (at LOR2 level) for South Australia next Thursday 31st May. We take a quick look….
This morning over on Twitter, I was pulled into a discussion that had started with respect to volume of wind energy curtailed in South Australia: The genesis of this twitter conversation was the AEMO’s “Quarterly Energy Dynamics – Q1…
Alerted by our NEMwatch dashboard, I delve into the data and see a scary degree of correlation between the (very low) output of wind farms in south-east South Australia, and (similarly low) output from newer wind farms in northern NSW.
An unexpected network outage in the south-east of South Australia restricts supplies from Victoria at a time of low wind supply in South Australia and results in the dispatch price spiking to $14,200/MWh from 11:30 and oscillating for the afternoon
On a day when high temperatures drove demand in Victoria above 9,000MW (and NEM-wide demand above 30,000MW) we saw some price volatility – with prices in VIC and SA up around $14,000/MWh
A starting list of all the factors I would like to delve into, in order to perform an objective review of what happened last Thursday and Friday in Victoria and South Australia
Some observations about the events across Victoria and South Australia of Thursday 18th and Friday 19th January 2018.
Reserve Trader dispatched
AEMO announces the possibility of dispatching “Reserve Trader” tomorrow to address a forecast tight supply/demand balance.
With high temperatures forecast for Thursday and Friday, here’s a quick look at what might be in store…
Prompted by a tweet referencing our RenewEconomy-sponsored NEMwatch Widget, we have a quick look at all-time peak instantaneous aggregate wind output in South Australia
Weather forecasts tell of an expected hot weekend on Saturday (in Melbourne & Adelaide) and then Sunday (in Sydney) – which has led to some news articles talking about “searing heat across the southeast putting energy supplies under pressure”. Let’s not get carried away – it looks like the levels of demand will be pretty moderate.
Today (Wednesday 27th December) sees some wild gyrations in aggregate wind farm output across South Australia. The (current) impossibility in forecasting these gyrations accurately is one of the factors contributing to higher prices seen today in South Australia and Victoria.
AEMO forecasts NEM-wide demand to exceed 32,000MW tomorrow (Monday 18th December), which is far higher than seen in December 2016, and one reason for the LOR1 low reserve notices.
AEMO has adjusted the formula (i.e. constraint equations) used to manage system strength in South Australia, which has been (since mid-2017) by constraining down the output of wind farms under certain conditions.
It’s 1st December 2017 – the first day of summer, and also the promised delivery date for the “world’s largest battery”. In this updated post we look at how it’s been operating.
It’s Saturday 25th November 2017 and what is currently known as “the worlds biggest battery” has kicked into gear – charging for a couple hours this morning.
The two emergency generators provide first power to the South Australian grid.
