Combined Solar & Storage Economics: Creating a credible grid scale business model in the National Electricity Market
Guest Author, Warwick Forster, looks at designing a combined solar & storage business model for the NEM

Some observations about Storage
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 continues to reach new milestones with a discharge rate of 100 MW today
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.
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.
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).
On batteries, and “fixing South Australia’s problems”
Some quick thoughts about Tesla’s promise to “fix South Australia’s power woes”. Which specific problem is Tesla promising to fix?
Interesting take, by battery maker Sonnen, on the “free energy” business model
Some brief thoughts on one innovative business model being introduced to the NEM incorporating batteries, demand response, and free energy
Forecasting is a Mug’s Game
The three main flaws that put boundaries on the usefulness of all forecasting/modelling
Increased complexity, and challenges, in this energy transition
Two slides (from BNEF and AEMO) that provide some context on the energy transition
The war for dispatch: Who will control distributed energy?
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?
What happens when energy is free?
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…
What role might Demand Response play in a (possible) future grid featuring high levels of intermittency?
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.
Wind in South Australia contributes to LOR2 warnings
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)
Approaching 62 hours becalmed on the mainland – what would this mean for battery storage?
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.
Electricity Pricing: An alternative to unlimited bill increases
A synopsis of one of the challenges facing the electricity sector – and a suggested solution
Is the changing generation mix in the NEM requiring it to start making capacity payments?
Some thoughts about Capacity Payments – given the article in the AFR yesterday
Three Possible Business Models for Distributed Storage
GSES recently gave a presentation at the APVI workshop in Brisbane as part of the International Battery Association conference.
The content of the presentation would be of interest to WattClarity readers, hence this guest post – which focuses on three possible future business models, that would mean very different outcomes to the incumbents that have become accustomed to “business as usual” over many years.
Electric Vehicles–some back of the envelope calculations
Some back-of-the-envelope calculations about what electric vehicles might mean for the National Electricity Market, following on from my presentation at the EUAA Annual Conference
