Some thoughts about the structure of FERC Order 745, and the arguments for & against setting it aside the in the US Court of Appeals – and the relevance for the Australian National Electricity Market
We play an active role in facilitating the Demand Response of large energy users, such that they can assist in making the electricity market more efficient.
Following the heatwave last week, a review of the symbiotic nature of the link between the gas and electricity markets in the gas-hungry state of South Australia
As the temperature cools (but the debate heats up) here’s a quick look of how much contribution there was from demand response over the past week.
Augurs to be an interesting day in South Australia today, with two (now three) price spikes already this morning – due in part to no supplies from coal, or from wind.
On the 4th of February at around 11am energy users in NSW appear to have curtailed their load in response to high prices, resulting in a significant drop in demand. Simultaneously, network conditions and generator rebidding caused the NSW pool price to jump back and forth between extreme prices close to VOLL ($10,000/MWh) and the Market Floor Price (-$1,000/MWh).
Some pictorial records of a day when a new record demand was set in Queensland.
Some quick notes about another price spike today in the South Australian region of Australia’s National Electricity Market
A look-back at 11 years of NEM history to reveal the nature and measure of benefits large industrial energy users can gain from curtailability in the NEM

Wednesday 28th January saw demand across the NEM jump to unprecedented levels, setting a new record of 34,843MW at 16:00 NEM time.

It was with interest that we stumbled on this article in the Herald newspaper talking about what happened on the 31st October in NSW
