High temperatures to give demand a kick in Victoria tomorrow (Wednesday 13th December)
AEMO forecasts higher demand in Victoria (and South Australia) tomorrow with the hot weather – and a slight LOR1 warning.
Electricity demand set to climb in NSW on Thursday with the hot weather forecast
With hot weather forecast for NSW this Thursday (especially in inland areas) it’s no surprise to see that the AEMO is forecasting higher demand on the day. Linked to this there is also a slight negative (local) surplus generation forecast.
AEMO updates generator combinations for SA system strength
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.
Big ramp in QLD demand Thursday evening to be first time above 8000MW this summer
Queensland demand ramped up, after the sun had gone down Thursday evening, to pass 8000MW for the first time this summer
How does frequency regulation help avoid Blackouts?
What are the lessons about frequency regulation that can be learned from the SA blackout?
The first stage of the Kidston Energy Park powers up
With Genex releasing an ASX announcement of first revenue at Kidston Solar Farm, we use NEMreview v7 to have a quick look.
Unfortunately no time for a “Best Peak Demand Forecaster” competition for summer 2017-18
For reasons explained herein, we’re unable to set aside the time required to run a competition on the “best peak demand forecaster in the NEM” for summer 2017-18.
Hornsdale Power Reserve (a.k.a. “the worlds biggest battery”) supplied SA for over an hour yesterday, peaking at 71 MW discharge
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.
Not quite summer and volatility returns to Victoria and South Australia
Some volatility with the hot weather on Wednesday 29th November – is this a precursor for summer?
AEMC released Final Determination on Five Minute Settlement on 28th November 2017
A quick look back at the AEMC’s Final Determination on Five Minute Settlement.
It’s complete baloney to claim that there’s “less than 1%” of peak demand in the NEM that is currently providing Demand Response
Some quick thoughts (before I run out of time) about why it’s all-too-commonly (but mistakenly) stated that there’s not much Demand Response in the NEM
If you increase your consumption of energy at a time when average emissions intensity is low, you’re not necessarily doing a good thing for the environment
A quick note about the need to avoid focusing on average emissions intensity (for the wrong reasons) and losing sight of the fact that it’s the emissions intensity of the next marginal unit of production that should be used for making short-term consumption decisions (if the objective is reducing your environmental footprint, as an energy user).
Hornsdale Power Reserve (a.k.a. “the world’s biggest battery”) begins to charge, and also discharges for the first time on Saturday
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.
Some simple calculations to help get my head around the scale of the numbers pertaining to Battery Storage
Some quick calculations performed today to help me try to understand what the future might hold, in terms of battery storage (given I’ve been asked to talk batteries today at the National Consumer Roundtable on Energy).
Following up, with a top-down (NEM-wide) look at daily solar production (small and large) through 2017
Following on from my earlier post about my own experiences as a small power generator (with solar PV at home), I’ve taken a broader look at solar PV production NEM-wide, including over the corresponding “stormy weather” period of October highlighted in the prior article.
What’s the market data saying about this Summer?
Guest author, Allan O’Neil, follows up a post in September (reviewing what the AEMO’s ESOO was saying about summer 2017-18) with this review of updated data
Some initial musings about my own Rooftop Solar Learning Exercise
There’s already been a large uptake of distributed energy generation data, and there promises to be much more to come in this energy transition. With this comes some significant challenges – along with opportunities (with respect to the electricity production itself, and also in terms of the data that’s produced). So in the interest of doing things better, here’s a detailed look at our own rooftop solar experiences at home.
Analytical Challenge – avoiding Recency Bias
Flagging the ongoing challenge of not extrapolating from recent performance to infer that “things” will always be that way.
The two, SA Government-owned, “Emergency Generators” produce first power whilst commissioning
The two emergency generators provide first power to the South Australian grid.
No Guarantee of Success
Our guest author, Allan O’Neil, poses a number of questions about the recently proposed “National Energy Guarantee” (NEG)
