In Australia, a Home Battery Boom Has Helped Cut Wholesale Power Prices in Half

Use EVs as energy storage. Millions of EVs form an energy reservoir. 20% of solar is curtailed now and q lot more in future, instead charge EVs. Pay the EV owners because they are creating a storage layer with their capital and power prices go negative hundreds of millions of times every year. No need of home batteries.
ghostly_s•25m ago
1. A couple orders of magnitude more people own homes than EVs; 2. EVs already are used as energy storage, but the thing about EVs is people want to use that energy to yknow, drive them.
thelastgallon•20m ago
That's why paying EV owners is th right incentive. All new cars will be EVs. In 20 years, all cars are EVs.
jmyeet•24m ago
The issue here is that EVs tend to be charged when the sun is down. When sun is up you tend to be at work or driving. The surplus power is coming from solar.
thelastgallon•21m ago
EVs are parked 95% of the time. If it's parked, it can be charged. Work places also have electricity.
KaiserPro•11m ago
but you're assuming that work provides parking. Its not a given, plus whats in it for the drivers?

plug my car in, it might be full, it might be empty, either way its racking up the charge cycles for no direct benefit for me.

Batteries on a house makes a better sell for customers, and also targets the problem of both over supply and over consumption at source.

cube00•11m ago
>Work places also have electricity.

Only households can access the free electricity window. They usually go further and also prevent businesses accessing reduced rates households can get during the day too.

bad_haircut72•18m ago
surely its possible to invent a "plug in road" system, then cars could charge (at least on highways etc) even when driving. I had this thought ages back when EVs first came out, to tackle the problem of long charge times when doing cross country road trips.
squigz•15m ago
I imagine this would make road repair even more common, intensive, and disruptive than it already is?

toasty228•11m ago
When I looked into it it didn't make sense to use an EV as a solar battery, the chemistry isn't made for high cycle counts compared to regular home/solar batteries.
rswail•10m ago
In Australia people do both. We don't have V2G yet, but EVs plugged in at home overnight with L1 charging can get charged by the home battery that was charged up during the day by the PV on the roof.

The solar PV and now storage rollouts in Australia have been one of the best government investments in public infrastructure in my lifetime here.

The more we electrify, the less reliant we are on the crude -> foreign refineries -> imported/distributed fuel risk.

Harvesting solar power is an awesome thing to do both at home and utility level.

PV and wind utility installations are being built with storage co-located, there are companies building synthetic condensers to maintain the grid stability and the job of frequency support is now done mostly by batteries, not gas.

We need to make electricity basically "too cheap to meter" and electrify our primary industries, mining and agriculture.

Wacari•9m ago
Agreed. V2G is actually one of the best DER strats out there. The EVs are already purchased, the batteries and PCS are already configured for bidirectional flow in most brands. Coordination/visibility problem remains at Dx level, but actually worth the investment.
black_puppydog•27m ago
As ever, Volts did a really good episode on this:

Worth a listen, both to learn about how ridiculous the US situation is, and just how good the "news" of abundant solar is.

collinmcnulty•5m ago
Levelized cost of electricity. All the costs that go into producing from a given source (capex and opex) divided by the total power generated.
kleiba2•26m ago
> The government has moved to make use of this surplus solar energy, including by offering free power in the early afternoon to homeowners in Queensland, New South Wales, and South Australia, regardless of whether they have solar panels on their roof or not. The goal is to spur more consumers to run appliances or charge electric vehicles during this window.

Taking the term "1st world problems" to new heights!

cube00•24m ago
You pay a higher daily supply charge and more per kWh outside this window so it's more like free (conditions apply)

The supply charge is 6% higher for the Solar Sharer plan, while the peak rate is 92% higher. Solar Sharer’s peak rate is almost double the flat rate. The off-peak rate is 17% lower than the flat rate.

wongarsu•20m ago
Some of that will be electricity usage that otherwise wouldn't happen, but a lot of it will be shifting load from times where electricity is carbon-intensive to produce to times where there is a surplus that would otherwise go to waste
Wacari•16m ago
cause they have massive operational issues induced by effectively must-run oversupply that has increased costs for both ratepayers (and sometimes shifted to the taxpayer to hide costs).

And then try to fix those problems with populist TOU rate magic (they won't be fixed), and bills continue to rise!! But hey, LMPs are down LOLOLOLOL

Wacari•21m ago
so in other words, heavily subsidize another technology (introducing cost shifts onto non-adopters, typically poorer people) to try and solve operational problems directly caused by oversubsidizing rooftop solar (another regressive cost-shift and extremely inefficient cost allocation relative to tx-connected solar) by bringing down wholesale prices (already a minority of the utility bill).

Fixed costs, the majority of the utility bill, continue to increase. But hey, LMPs (something residential tarriffs are not that exposed to) are lower!!! LMFAO

rswail•6m ago
Wholesale power is ~37% of the customer bills.

The other costs are the "poles and wires" distribution network and the HV transmission network.

The government is also building out the transmission network to various renewable energy zones, which has the added benefit of making the transmission network more resilient.

With large coal plants, the network was only one interconnector failure from blacking out a state (as happened to South Australia).

Now there is a much better network of interconnected transmission across the entire east and south coast of Australia, covering something like 80% of the population.

The government just bailed out an aluminium smelter that was going to close because of the increased cost of power because it was relying on an old coal plant. Now that will be replaced with renewables.

So we get the benefit of the continued operation of the smelter, as well as the build out of replacement generation for the old coal plants at EOL that will be closed by 2030.

AnotherGoodName•13m ago
It started with a solar boom, many small home scale solar roofs popping up everywhere. Australia has a free trade agreement with much of the world, including China, and solar panels have literally dropped to 1/50th of the price they were in 1990 ($10/W to $0.2/W today). A shout out to the work that was done to establish dynamic grid pricing too.

Anyway that caused power prices to reliably go negative during the day as the solar boom led to too much energy being produced. So everyone started buying batteries (you can even get live feed in/out pricing as a consumer). In fact the government even today will pay you a $3000 subsidy to go install a battery. This is in a country where people can buy cheap batteries with no tariffs (free trade's amazing, seriously!). So everyone who could started doing it. For those in apartments etc. that couldn't easily install solar and batteries they won too since the entire power grid is now half the price.

Another consequence of all this, aside from the cheap power prices during a datacenter boom and Hormuz blockade is that fossil fuel usage is plummeting. Particularly gas https://ieefa.org/resources/slump-eastern-australia-gas-dema... . No need for a gas peak power plant when the grid is packed with batteries. Which is helpful since one of the main issues with the current blockade is a lack of gas globally.

pnw•3m ago
If you read the article, most of the decline in gas consumption in Australia is from changes in industrial usage. Residential demand is only down by 6% and part of that is likely due to the effective ban on gas in new residential construction which started in 2023 in Victoria. Prior to 2023 residential gas usage was increasing.
plantain•13m ago
The program has so far spent $2.5bn, and installed 11GWh. That's just the cost of the subsidy (~30% discount), not the cost of what home owners tipped in.

Utility scale batteries are now at ~$66m/GWh, or about ~$726m equivalent.

It does not make sense for everyone to be doing a bespoke installation inside their own home. It is ridiculously inefficient.

We are a society. We don't build our own roads, water, grid, schools, hospitals. Why have we suddenly decided to DIY our own redundant power sources? (A: failure of governance)

ericmay•6m ago
> Why have we suddenly decided to DIY our own redundant power sources?

Because government is failing to address these issues?

Back in Trumpistan we had some storms roll through my area the other day. Power has been out for some (not me, thankfully) for a couple of days in a major metro. It was a bad storm and I do not fault the crews who are doing hard work out there repairing everything and it takes time.

But what the hell are you supposed to do when the power goes out and it takes a few days to get turned back on? Well, spend $10,000 - $20,000 and install your own backup power. Is it inefficient? Sure! Does that matter? Absolutely not.

ch4s3•3m ago
This isn't a federal government issue in the US. Local and state governments dropped the ball here. No one wants to pay what it costs to bury power lines in most locales, and we have a ton of byzantine regulations that make it slow and expensive to add generation capacity.
alexpotato•6m ago
There was an article a few years back about how homeowners in Hawaii were buying solar panels to try to get cheaper power.

Then the local power company realized that as well and started shifting to solar with the net result that it became cheaper to buy the power company supplied electricity than from your own solar.

surfmike•8m ago
California is also adding a lot of battery storage… but why are electricity prices falling in Australia and not in CA? Are they outpacing us?
zipy124•4m ago
"Energy Minister Chris Bowen said that Australia now has more home batteries than the United States, which has a population 12 times larger."

Yes.

testing22321•8m ago
I put 7.3kw of panels on our roof for $0 of our money thanks to a $5k rebate and $8k interest free loan. It makes 7.2Mwh of power a calendar year, which would cost $1000 if we had to pay for it.

So for 8 years we pay the loan instead of for the power, then we get -25 years of $1000 a year in our pockets. The price of power is also pre approved to increase a minimum of 5% a year every year here, so the savings will be more than that.

Right now we get a 1:1 credit for anything we put into the grid. If and when that changes I’ll get a battery.

The kicker? We’re in Canada in a tight valley where it snows a ton. If it works here…

greenleafone7•7m ago
This whole thing started because of some power pylons got destroyed and electricity was not restored for about a year right?
skew-aberration•5m ago
The subsidy was closer to 70%, and in my case I was paid the equivalent of about 10 years of free electricity for a battery with a 10-year warranty. In total somewhere around 5-7 billion AUD was paid out (not yet public) - the wholesale market for comparison is around $16B AUD annually. Personally, I would have preferred it was used to build grid scale storage instead of funneling tax money to the relatively wealthy (myself included). Given the extreme volatility of power prices, a figure such as '47% decline' should be taken with a grain of salt - but power prices are certainly a bit lower than last year.

Depends. residential fleets v commercial fleets. different behaviours.

Even most residential batts that get plugged in when they get home typically have SOC >40% (depending on jurisidiction).

KaiserPro•8m ago
you're gonna have to expain that to me.

so cheaper 'leccy prices are bad? or that this upfront cost to get batteries installed are bad? even though long term costs will be dropping?

I mean whats the cost of 30% of 500k batteries compared to creating a new peaker genny or five?

boxed•6m ago

Sort of. While not really mainstream, there are private roads (and long driveways), wells, and a (limited) amount of home-schooling. Not hospitals obviously as that requires specialized training and equipment.
