The NSW-based distribution network Ausgrid says it is looking at building “community-style” battery storage facilities as it looks to get “closer to consumers” and help usher in the next stage of the energy transition.
CEO Richard Gross, in an interview with RenewEconomy ahead of a presentation at the AFR Energy Summit on Monday, says the network operator is investigating how “community storage” – installed in the network’s subs stations – can serve the needs of both the networks and consumers.
“I see a world where I am sitting at home with an app, seeing opportunities to trade, to arbitrage price movements, and all this can be done while I am sitting watching Game of Thrones,” Gross says.
Exactly how these platforms work, and the business models that will underpin them, is yet to evolve. “There will be stuff we haven’t thought of,” he says.
But Ausgrid, and other networks, intend get in on the ground floor, as they intend to do with all the possibilities created by electric vehicles, charging networks and vehicle-to-grid.
After all, they own the network. And while Gross won’t go as far as other network operators have said in the past, and declare no future for the traditional “gentailers” that combine centralised generation and retail operations, he says he is pretty happy to be boss of a network.
“If you look back 10 years ago, it was about the death spiral on grids,” Gross says. “Now grids are a big part of the solution in allowing renewable energy to connect, and a big part of giving customers options for what they want to do.”
Is the network then the future, rather than the gentailers?
“I can’t comment on that. The grid is a pretty good spot to be. Over time there will be more usage of grid, more substations, more peer-to-peer trading across the grid. That will facilitate the future much more so than the retailers.”
It’s a remarkable transition for the network operators in general. A few years ago, as Gross mentioned, the great fear was grid defection. Now, it looks to be load defection as individual consumers become their own generators.
But they need the grid to be able to share energy and trade with others. So the networks have gone from raising the drawbridge to lowering it, inviting new technologies and ideas on to their platform.
They see a role in the future, with much more clarity than the generators and retailers, and sooner or later they are going to be competing for access to the consumer – something the likes of the big three gen-tailers have been fighting for years.
“Over time we would like to have more direct access to the customer. You start to wonder why, if mum is trading with her neighbour, does she have any need for the retailer to be there.”
“Over time, the distributors will get closer to the customer. Various business models will allow that to occur …. and the current distinction between retail and distribution will blur.”

I think Mr Gross is right, in fact I can see retailers merging with network owners in order to stay relevant. Some will miss the opportunity or fail to merge and disappear.
One thing for sure is that who has the grid needs the grid regardless whether they have PV and a battery as they can't sell their excess production without it! And if the networks start being greedy it will only cause defection and that won't help their business model at all.
ABC 7.30 just had Energy Australia whingeing about too much solar (Thurs 11 Oct). Pity they didn't interview Richard Gross.
I don't think it was EA whingeing.
Unfortunately the following website gives very little information about the power density and related issues like discharge rates but given that many units of its zinc/air product are in uses it makes an interesting read in terms of ESS costs and how it might be incorporated into community ESS versus individual ESS systems:-

Another thing of note is that Alevo has been sort of resurrected in the form of Innolith:-

Time will tell for these and many other technologies but it is so annoying that people, especially in the LNP, have such little interest in the emerging renewable energy technologies.
If you leave aside the thick grid links from traditional concentrated centralised generation areas (Latrobe and Hunter Valleys, Surat Basin etc) back to their large metropolitan loads, the local sub-transmission and distribution grids will feature highly as relevant players in shifting excess electrons between areas of local changeable generation (rebalancing the entire network). If you have a series of community batteries installed in a number of Zone Substations, then any sharp increases or decreases in load can be smoothed out and leveling the overall load for the generation assets (be whatever or where-ever they might be).
The analogue is your internal combustion engine car with its alternator (generation) and battery (storage). Both storage and generation objects are needed in that model. The car won't run very long on the battery without charge and the alternator isn't capable of providing sufficient output to power the load or to start the engine, without the battery. Its very much a synbiotic relationship.
Installing batteries at Zone sub-stations make sense on many levels. The practicality of installing batteries in all zone sub-stations is a big ask. However a few large battery installations in the larger zone sub-stations may offset the need to augment sub-transmission links back to Transmission or Bulk Supply sub-stations as the effective load draw is normalised or averaged, away from large peaks and deep troughs in the flows which would normally occur if there was no battery.
