Lessons Learnt from Amber’s first summer of Spot Exposure in the NEM
Now that summer 2018-19 has passed, we can reflect on our experiences as a new entrant energy services company facilitating spot exposure for residential energy users – and hence expanding the scope for Demand Response in the NEM.
First scorching summer day for the year and the sky rocketing price of electricity.
The first day of scorching summer temperatures for the year has been matched with elevated electricity prices in New South Wales, Victoria and South Australia for most of the day. Queensland and Tasmania experienced small patches of high prices yet…

Reviewing the pattern of spot prices for Q2 2018 suggests that we’re far from out of the woods, yet
Returning to the theme of analysis of Q2 prices (completed in 2017 and 2016 due to Q2 historically being an uneventful period) we see that prices have backed off from the “off the charts” level of 2017, but are still much higher in all regions than most other regions. In some cases results are second worst in 20 years.
Recapping a shaky week for the supply-demand balance in the NSW region last week (Mon 4th June to Fri 8th June 2018)
The start of some analysis that helps to identify the variety of factors that combined to give a shaky balance between supply and demand in NSW last week.
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A comment made by TransGrid at the Energy Networks 2018 conference today jolted me to update my (somewhat) outdated paradigm of declining demand.
A timely reminder of the need for *much* more diversity in wind harvest patterns
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.
It’ll be hot in parts of the NEM tomorrow (Saturday 6th Jan) but don’t expect demand to be too high – and don’t be trigger happy on the Emergency Demand Response!
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.
Hot weather sees NSW demand at 13,000MW and NEM-wide demand above 31,000MW
A quick review of a day when NSW demand was forecast to be high
NSW demand currently forecast to peak up at 13,500MW on Tuesday 19th December
Current forecasts at AEMO show NSW demand forecast to peak above 13,500MW (which would easily be the highest December demand in NSW since 2009).
Coincident warm demand forecast for VIC and NSW tomorrow late afternoon (Monday 18th December)
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.
