Upgrading our existing coal thermal fleet to increase efficiency and flexibility could provide a cost-effective opportunity to add dispatchable capacity and lower the overall carbon intensity of our electricity sector.
A new peak Scheduled Demand and Operational Demand in Queensland today with Scheduled Demand still over 9,100 MW after 8 PM.
Queensland experienced a new record for Scheduled Demand for electricity today – but what’s particular staggering is how late in the day it happened!
A brief look at the numbers with the temporary coal supply issue affecting Loy Yang A and Loy Yang B overnight
Looks like being an interesting day on Wednesday next week (14th February 2018) with high temperatures currently forecast for parts of both QLD and NSW
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
Electricity demand in Queensland today reached 9072MW in the 16:40 dispatch interval, passing 9,000MW for the first time this summer.
Yesterday (Sunday 28th January) saw electricity demand (both Scheduled and Operational) above 9,000MW in the heat. Others have noted this was the highest-ever non-working day demand in Victoria, but I have not delved in detail.
It seems to us that the people at either extreme of the Emotion-o-meter are causing this energy transition to see-saw off the tracks. For this reason they are Villain #3.
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
A quick review of a hot and sticky day in Queensland that saw high levels of demand reached on a Saturday – with demand peaks tomorrow forecast to be just as high (on a Sunday!). Today saw the first major price spikes in the Queensland region of summer.
AEMO’s demand forecasts for Saturday 6th January 2017 were about 500MW below what the mark turned out to be. It appears that this is due (at least in part) due to difficulties in forecasting intermittent generation which acts to reduce “Scheduled Demand”.
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.
