Electric vehicles will drive 20-fold lift in battery storage capacity by 2030, says AGL

AGL says electric vehicles will see result in a 20-fold increase in behind the meter battery storage capacity in Australia by 2030, and it wants to be able to harness that resource.

AGL says it anticipates a 20-fold increase in behind the meter battery storage capacity in Australia over the next 10 years, driven by the influx of electric vehicles which it says will account for half of all new car sales by 2030. And it intends to tailor its business accordingly.

In a sure sign that AGL is recognising the shift from a business model based around centralised generation, AGL says its future business model will be based on the “shared” economy in electricity and transport, focused around customer choice of rooftop solar, household batteries and electric vehicles.

In its annual “investor day” presentation to analysts on Wednesday, which also included news of its contract to buy four large scale batteries in NSW, and its intention to seek other big battery opportunities in other parts of the grid, AGL predicted there would be 2.6 million EVs on the road in Australia by 2030.

This would mean that EVs would account for around 50 per cent of new car sales – just as outlined by Labor in its pre-election policy targets that were mocked by the Coalition and conservative media.

Not only that, AGL expects the shift to autonomous driving and shared transport to also happen quickly. “Less than 1/3 of consumers will actually own cars,” says Dominique Van Den Berg , the head of distributed energy at AGL. “Electric vehicles will accelerate that transition.”

The company’s presentation noted the number of homes and businesses with battery storage would likely jump to 700,000 by 2030, but in some scenarios could match the current coverage of rooftop solar, or about one in four homes, or nearly two million.


However, this is expected to be dwarfed by the number of electric vehicles on the road, which could increase the battery storage capacity 20-fold by 2030, to a total of 40GWh, with most of that coming from EVs.

Some analysts, such as Bloomberg, have suggested that the battery resource from EVs could be ten times that number once the fleet becomes fully electric, and AEMO, like other international grid operators, is also starting to study how it can tap into that resource.

The trick for utilities like AGL will be to understand when, where and how they will be charged and able to provide energy back into the grid, and how to harness those assets into their business models and consumer offerings. AGL’s focus in on “orchestration”. But it’s yet to be seen how that can be done.

AGL’s efforts are being driven by changes in technologies and also emerging competition from new retailers eyeing opportunities in distributed energy. The UK-based and Mitsubishi backed Ovo Energy this week won a retail licence to operate in Australia, and is expected to bring its focus on combining rooftop solar, battery and electric vehicle charging options for consumers.

Oil giant Shell is also looking to enter Australia’s electricity market, and has made an agreed bid for ERM Power, as it prepares for what it sees as the inevitable “electrification” of transport and manufacturing.

AGL’s Van Den Berg says the shift to EVs is inevitable, given the expected arrivals of more models, increased range, and when prices fall to the same ticket price of internal combustion engine cars, than the uptake will soar.
“Half of all new cars sales will be electric vehicles,” Van Den Berg said. “The principle of orchestrating a home battery is exactly the same as for a mobile battery. But when, where and how we charge is more complex.”
“We are looking at more than 7000MW (of storage) in system. That’s the equivalent of 28 open cycle gas turbines,” she said. “In many respects we have got to manage these assets in the same way as we manage gas assets.”
To illustrate the point about the so-called “shared economy”, and how it applies to the energy industry, Van Den Berg gave this example of how that “orchestration” could work, how it allowing the utility to tap into the household battery resource, and how it could allow the household to tap into high priced events.
“This is the approach of the shared economy business, the value of these assets is worth so much more with (connection and orchestration) than without,” she said. The graph above shows the benefits of using the battery in high prices events that could deliver extra revenue (maybe close to $300 a year) that would not be available otherwise.
In fact, AGL wants to be able to manage these assets in much the same way as it does larger assets on the wholesale market. One of the big targets will be the “solar duck curve” which is lowering demand and prices in the middle of the day.
Price variations are increasing and the company intends to use this price signal, and the need for dispatchable and flexible capacity as more coal plants exit the market, to invest in batteries and pumped hydro power station.

    The duck curve will turn into a duck cliff with enough batteries which all finish charging at 11AM.

    The question that springs to mind is why would I, as a consumer, bother. If they wrangle the charges around so that I still end up paying for electricity then it would make more sense to simply be off grid.

    Even a lower end BEV would keep my house running for around 4 days even if my solar delivered no electricity. I reckon with a slightly larger PV array I would never need the grid and could easily still do my daily drives. (granted I’m unemployed so my car would be charging at home when not being used)

    So will the electricity companies be paying us each quarter? Or, will they somehow still seek to be the recipients of our cash and our electricity

    It can be done and it could work realy well …. it could happen here in Australia but not for 10 years and not with the government we have now … it could work in California or Norway … if we can just put in more solar on houses and businesses and batterys then we can kill coal one solar panel at a time ….
