A rare excursion above 9,000MW this summer in Victoria on the back of some hot weather today.

Moree Solar Farm becomes the fourth of the Large-Scale Solar Farms outputting to the NEM (but 3rd publishing data)
A quick look at large-scale solar data for the NSW region, with the recent addition of Moree Solar
Hot weather (and LNG gas demand) drives Queensland electricity demand to a new all-time peak
Yesterday (Monday 1st Feb) we saw a new record demand set for the Queensland Region of the NEM. Today was even hotter…
Queensland demand forecast to break 9,000MW for the first time next week
AEMO’s current PASA forecasts indicate a likelihood that we’ll see a new record set for electricity demand in Queensland early next week.
NSW electricity demand a shave higher than last week
Hot weather pushes electricity demand in NSW higher than the high met set last week – a new “highest point in summer, thus far”
NSW demand tops 12,800MW and reserves tighten today – prior to the cool change
Today was the turn for NSW to feel the heat – with demand rising and supplies stretched as a result.
NEM-wide demand breaks 32,000MW – highest so far this summer
NEM-wide demand exceeds 32,000MW for the first time this summer (so 2,000MW higher than the previous summer level, already). A volatile day in pictures…
Queensland demand rises above 8,000MW
Queensland demand rose above 8,000MW
NEM-wide demand climbs above 30,000MW today
Demand begins to wake from holiday slumber with temperatures up across the mainland.
A collection of some core analytical challenges
A collection of articles speaking to some core analytical challenges. Others are categorised elsewhere – like my prior thoughts on three reasons why forecasting is a mug’s game.
What’s been happening with NEM-wide demand so far this summer
A quick look back over summer 2015-16 to date to see what level of electricity demand has been achieved.
Sun Metals submits rule change request to AEMC – for optional Five Minute Settlement
On 4th December 2015, Sun Metals (a zinc smelter in northern Queensland, and also one of our initial deSide® clients) submitted this rule change request to the AEMC: In the 10-page proposed change, my sense is that the key points…
Puzzling through three rule change requests
Some ideas that I have been puzzling over – about the overlaps and contradictions between 3 rule changes under consideration at the AEMC currently
1) The Demand Response Mechanism (better known as the Negawatt buyback mechanism)
2) The Bidding in Good Faith deliberation
3) The Requirement for Price-Responsive (large) Demand to bid into central dispatch
Hot weather pushes NEM-wide demand higher than the peak for summer 2014-15 (and we’re not even in summer yet…)
It’s not even summer yet and we’ve already exceeded the high point of summer 2014-15 with the current hot weather…

It wasn’t the horse race that led the large drop in load in NSW coincident with the race
Responding to comments in social media about how “the race that stops the nation” might have contributed to a drop in demand in NSW
If your horse did not come in today – here’s a better chance to win a BBQ (and possibly* a bottle of Grange)
The competition is back, for another summer (with 7+1 prizes on offer). Read through for details…
What role might Demand Response play in a (possible) future grid featuring high levels of intermittency?
Back on 8th October, I spoke at All Energy in Melbourne on this topic. Given the questions posed after the session, it seemed that it might be of value to some WattClarity readers if I narrated over the top of the presentation and included it here, for future reference.
Ramp rates, for “Unserved Demand” much higher in this future world
A quick look at how ramp rates would vary (for “Unserved Consumption”) in the hypothetical “10x” high intermittency grid.
Considerable spillage, in the high intermittency “10x” scenario
Continuing our analysis of these hypothetical future scenarios to understand the shape of “unserved energy” and hence the potential contribution of Demand Response – today I post about energy spilled in a future with high intermittent generation supply.
