UQ’s Andrew Wilson pens a case study on the market events that occured on Tuesday the 13th of October in the QLD region, in which he examines the relative performance of UQ’s 1.1MW behind-the-meter battery during this period of market volatility.
Ronald Brakels looks at the state of the home battery market and reflects on how past predictions of its evolution look in hindsight.
The University of Queensland’s project team that was involved with the installation and operations of their 1.1MW Tesla battery presented a webinar and exhaustive Q&A on the first results of the project.
Guest author, Andrew Wilson, presents a case study of the performance and results from the University of Queensland’s 1.1MW Tesla Powerpack system during Q1 2020.
Took 2-3 times longer than planned (as there were a few different interesting observations that came out) but here is our initial – and perhaps only! – review of what happened in South Australia on Thursday 19th December 2019 (i.e. yesterday).
Guest Author, Warwick Forster, looks at designing a combined solar & storage business model for the NEM
Last minute complications mean that I cannot speak at today’s “Queensland Smart Energy Summit” (with Jonathon Dyson being an even better substitute). Here are some of the observations I would have liked to discuss with the audience there…
Hornsdale Power Reserve a.k.a “World’s biggest battery” achieves new milestones – discharged at a rate of 100MW and charged continuously for nearly 3 hours.
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.
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 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).
Some quick thoughts about Tesla’s promise to “fix South Australia’s power woes”. Which specific problem is Tesla promising to fix?
Some brief thoughts on one innovative business model being introduced to the NEM incorporating batteries, demand response, and free energy
The three main flaws that put boundaries on the usefulness of all forecasting/modelling
Two slides (from BNEF and AEMO) that provide some context on the energy transition
In today’s energy sector, it is rare to get electricity networks, retailers, generators and system controllers in the same room at the same time. In a deconstructed market about to be transformed by distributed energy, how will decisions be made around how it is dispatched?
One scenario holds that the price of energy supply might drop to the point where it is effectively free. Here’s some of what we’re thinking about…
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.
Windy conditions persist – and bring with them their own challenges for the AEMO in managing the security of the system
(PS wind contributes to, but there are other factors discussed in the post)
Some back-of-the-envelope calculations being a starting point to help me understand how much real contribution electric vehicles might make in feeding back into the grid when intermittent generation is absent.
