Edited to add: Clarification required in the title that the free energy is only between 11am and 2pm
Very interested to see how this turns out. Ultimately we want the transition to benefit both consumers and producers / distributors (the industry). The problem from the rapid uptake of solar in Australia has been an over-supply during this 10/11am to 2/3pm period. If that over-supply is suitably encouraged to be soaked up then hopefully consumers can reduce their power bills whilst the industry has less effort in managing the oversupply and less stress on infrastructure.
It's also about time that those who lack the means or situation to have solar panels of their own can get some advantage, in a 'herd immunity' kind of way.
I'm in the privileged position to have had solar panels for over a decade, and now have a battery as well, and it was very obvious to me at the time that, in regards to solar, it cost money to save money, so if you couldn't afford it then the savings are inaccessible.
This change hopefully helps those who need it, at least somewhat.
this applies to NSW, South Australia and part of Queensland.
so NSW and South Australia will be staggered in real time as they are in different time zones.
As for everybody in the same time zone .. they are all seeing the same sun angle at noon (more or less) and all sharing the same over supply of power from all the grid connected solar power rooftops and farms. It's free surplas power during that time frame.
My home is in London UK and is relatively small and efficient, but 8kWh may be higher than our peak demand ever over more than 20 years in this house...
UK appliances cap out at 13A, or 3.1kW. Electric cookers may be on higher current wiring, but seem to be rated at 3kW max anyway.
I think the only way most people could get to 8kW continuous without an EV would be to turn on their electric oven, grill, and all spots on their electric hob. And the kettle.
To be fair, in a modern Maslow’s Aussie Hierarchy of Needs energy is a foundational Physiological Need, whereas energy for crypto mining is a luxury item best placed out past the outhouse of the main pyramid.
From the article; this applies to NSW, South Australia and part of Queensland.
So yeah, not universal yet. But the precedent means it's moving in that direction. If WA homes end up producing lots of solar at midday then this opens the door there as well.
It's still worth it if you have a lot of load you can shift to the middle of the day (like a pool heater or battery), but for most 9-5 workers you just end up paying more at the times you're actually home.
Smart meters are free, most people already have one.
Sure, a battery isn't available to everyone. But I is available for many.
One would have to do the math, cost of battery versus 24kw free daily. But clearly for lots of people the math will work.
A side effect of policies like this is effectively getting people to invest capital to time-shift elec usage. That's good policy. Reducing the peaks in consumption solves other problems.
I thought most Australians had different pricing for peak/off-peak. I'm paying 39c/kWh for peak (3pm to 9pm) and 20c/kWh for off-peak (9pm to 3pm the next day).
Incentivizing usage during peak times makes total sense, but if price swings are this wild, how are grid scale batteries not highly economical? My rough ballpark math was that you need roughly 20 kilowatts of battery storage to make this issue basically nonexistent, and that would cost about 10 billion dollars, which doesn't seem that much for this.
They've already burned at least $15bn on that disastrous Snowy Hydro "battery" project... Could've just rolled out consumer batteries on a large scale instead.
The cost of the Snowy 2.0 pumped-hydro project is estimated to range from \(\$12\) billion to as high as \(\$42\) billion depending on the scope of costs included (such as direct construction, interest, and broader transmission). Originally announced in 2017 with a $2 billion price tag, the project has faced massive scale and logistical blowouts. The cost of the Snowy 2.0 pumped-hydro project is estimated to range from $12 billion to as high as $42 billion depending on the scope of costs included (such as direct construction, interest, and broader transmission).
That said , hydro systems have a LONG LIFESPAN - 100 YEARS ?
Batteries need to be replaced every X years.
So the ecomiomics of the comparisoan would need to be calculated ...
At current battery project prices, matching Snowy 2.0’s roughly 350 GWh of energy storage capacity with Tesla Megapacks would cost around AUD $218 billion [0] and require Tesla’s entire global Megapack production capacity redirected to a single client for five years.
$15 billion is far more than Snowy 2.0 should have cost. But it remains substantially cheaper than any lithium-ion battery build for bulk storage. Storage on this scale is essential in a post-coal electricity grid, and batteries are not (yet) plausible substitutes for bulk storage.
[0] This assumes linear scaling. In reality, placing an order like this would grossly distort supply and demand on many levels. Thus the cost would ultimately be superlinear.
Yeah the battery storage story has to acknowledge the fact that global production capacity simply isn't actually high enough to deliver that many batteries so we need alternative solutions to the problem as well.
Snowy 2.0 has major limitations on what it can supply, the headline number is very misleading.
And the comparison shouldn't be to batteries alone, but solar/wind and batteries. The former can be used directly and fill the batteries repeatedly on a timeline that is predictable.
It provides no extra value for the electricity to be stored long term if for the same money you can generate and store it short term.
That was exactly the point of the project though - it was designed by the conservative side of politics in our country to try and crowd out investment in batteries and other renewables while taking enough time to build to keep coal plants operating longer in the meantime.
It didn't work at all for that though - we had a lot of private investment in large-scale batteries anyway, because the cost came down quickly just as most people (apart from the conservatives) expected. Then the other side of Government got in and put a subsidy scheme to get hundreds of thousands of home batteries installed, which has been multiple times better bang-for-buck than the Snowy 2.0 scheme, as well as taking far shorter a time. At the same time coal plants are shutting down as expected because they are increasingly unreliable given their old ages.
Snowy 2.0 be an expensive stranded asset basically, it will work and be somewhat useful but extremely uneconomical so basically relying on the cost being written off - if it had to recoup any investment then it couldn't run because it'd never be able to sell the power for high enough.
I think it's less a question of batteries being economical, and more a question of the relative economics of batteries vs solar panels.
After all, if the highest demand is between 16:30 and 19:00 you could use batteries to store power at 12:00 and sell it at 18:00 - or in famously sunny Australia you could build enough solar panels that solar output at 18:00 matches power demand.
If batteries have a solid 9% return on investment, but solar panels have an even better 12% return on investment, panels will outpace batteries even though the batteries are a decent investment.
(Also, from a politican's perspective, making batteries highly economical is how you get batteries built. And an awful lot of pro-environment policies involve raising taxes, banning things and creating new chores; it's nice to have some green policy announcements that actually benefit voters in the short term.)
You won't get 12% return if your panels generate electricity which is only paid between 18 and 19, because there is already overcapacity between 16:30 and 18.
One of my co-workers (I'm Australian) has 500 kilowatt-hours of storage at home...which is wild. Much more common is the 10-20 kilowatt-hours of domestic storage for a house.
That's ~8 used EV batteries. Each cost less than 10k, maybe 6-8k AUD.
If you know your way around high voltage DC, got a tractor and appropriate emulator - not exactly difficult or super expensive to pull off.
Granted it's pretty uncommon setup as grid batteries themselves are pretty cheap too and used EV battery is simply too large for home user, too much hassle, liability, etc to save like $2-3k.
Does he have a saltwater aquarium, or any other hobby that can make use of it? If not, I can highly recommend that he get into it, if he's into that kind of overkill :)
Is it so out of the ordinary that a government tries to help people save money or what's the question? Sounds like you've only had the American experience in life unfortunately.
Yeah this is why a lot of people were thinking that the Australian opposition asking for spending $40-50 billions for nuclear that would come online in 20-30 years and to keep using coal and gas till then were being stupid.
The fundamental costs and margin requirements in the system haven't changed.
This is a government-mandated electricity plan (a default market offer) that competitive electricity retailers are now required to offer. Those retailers still have network costs, environmental costs, energy costs, and administration costs to recover, and so prices at other times of day necessarily go up.
Some consumers may be better off on this plan (generally at the expense of other consumers), and some will be worse off.
It’s very cool to see what happens where there are simply so many residential solar installs. Power price goes negative during peak sunshine hours so they just give it away.
Solar installs benefitting everyone, even those who never got solar.
As an Australian, the lack of anxiety and guilt you get when you're using 10-12 hours of air conditioning in the middle of summer and not paying for a cent of it because your solar panels are covering is worth more than anything
Why shouldn't that be true practically every consumer home in the world?
Yes, grid scale deployments are cheaper, but I'm generally guessing a lot of the grid scale solar deployments do not price in the grid infrastructure adaptation costs, and I'm not even talking about grid storage.
Consumer rooftop solar is fundamentally democratic: it reduces reliance on centralized institutions for power delivery, Make society a lot more resilient in bad weather and other emergency situations, insulates everyday people from wild variations and petroleum and other consumable energy availability.
Combined with plug-in hybrid electric vehicles, it would enable electrification of 80 and 90% of daily driving without grid infrastructure costs.
> Why shouldn't that be true practically every consumer home in the world?
Here in Sweden nearly all of the electricity bill you pay is concentrated on the winter months when there is literally zero sunshine. Even then solar is popular here. I calculated that installing solar would take around 10 years or more to pay for itself, but I have very little hope to stay in the same house all that time so for me it seemed like a bad investment.
That said, if you live in places where it’s sunny most of the time even in winter, like Australia, then solar is absolutely great, just don’t assume most places are like that.
Yeah totally, nice to be able to put the AC/heater on "for free". I even got a negative power bill once!
In my specific case, I barely use much power so home solar covers basically all of the usage, my bill is dominated by the daily charge, so the usage component is practically irrelevant to me.
If you’re using rooftop solar then presumably the net heat generated by your aircon is the same as the amount your roof is no longer absorbing. Otherwise you just described a perpetual motion machine?
Yeah, it's been great to see the uptake of rooftop solar in Australia.
One downside is that large scale solar projects aren't profitable any more. It kind of sucks for the investors that adopted green tech, that they aren't getting a good payoff.
The good news is that co-located solar and battery projects are still profitable, but capital costs are higher and payback period of batteries aren't as good.
Dynamic pricing and deployment of digital smart meters should by mandatory in all electric grids dominated by renewables. Large electric consumers are already buying electricity at dynamic prices, small consumers should have the same incentives to shift the demand to day hours.
I'm so on board for this. It would be kind of fun to wire all my appliances in to home assistant to have the dishwasher / dryer / etc all run during the free hours.
I imagine eventually we might end up with some thermal storage where during peak renewable production you heat/freeze a large tank of water and then utilize it to heat/cool your house for the rest of the day. A large tank of water is much cheaper than battery storage.
Batteries are massively more expensive. Thats why the utility companies are just giving consumers free power over building their own grid scale batteries.
A tank of water is cheap, it’s just not possible to distribute hot water over the grid. But it’s very realistic to store it locally and use for heating and cooling. Which is the bulk of power usage anyway.
Storing energy in hot water is common is sunny regions, for example Turkey.
Some large cold storage facilities in Germany are trying to optimize electric demand to use cheap peak day electricity. But they have to observe limitations in range of temperatures and capacity of cooling devices.
Many of us with solar already do this manually, we run the appliances once the sun is up. Even the hotwater heater is programmed to only heat during the middle of the game.
I've been daydreaming about the tank of water idea as well, but the amount of panels you would need on the roof would be crazy.
Ideally, they should pay the EV owners because electricity price goes negative. The EV owners are spending their own money to create a scalable on-demand storage infrastructure. This saves CapEx/OpEx of BESS and also eliminates peaker natural gas plants. EV owners should be paid once for allowing storage, and paid again for using the power to supply back to the grid (V2G).
I miss having Griddy in Texas. Direct access to the wholesale market is probably not good for the lower end of the consumer segment, but for people with some functional marbles it can make a big difference on the demand side of the grid.
I feel like they had to kill griddy before all the powerwall solutions started showing up. We simply cannot empower the peasants with both things at once. The ability to store energy makes access to wholesale prices substantially more effective.
I'll never forget the days where we would get push notifications about negative prices. I'd throw the dryer and oven on every time to try and unwind the meter a bit.
You might check the rates on Tibber as well. A lot of companies that offer a "free" usage period tend to just move the cost around. If you're comfortable taking the risks associated with a wholesale supplier, then you can likely save a ton of money without even changing your consumption habits.
During this past month with the heatwave, my electricity bill was only about €50 despite running airco all day most days. I have 6 solar panels on my roof for reference (was 3k installed I believe). If I was willing to turn off the A/C at night, I could have easily cut the bill in half since most of the billed usage was between 18-21:00.
You need a battery to take advantage: then you may as well use a direct to market option like Amber. Which benefits grid stability too. 3 hrs without a battery is useless in Australia. As you generally use electricity for heating/cooling and need it longer than that esp. cooling.
The payback time was already well in excess of 10 years, but now that power is free during the day, you can't count those hours as helping pay down your investment. Payback time will be 30 + years at least. You are much better just enjoying your neighbors solar rather than paying for your own.
(Feed-in is about 3c now I think. Was 12c when many people bought their panels.)
Note: My state 100% renewable energy so reduction of carbon footprint has not bearing on my solar decisions.
This also feels like a fairly heavy handed way to encourage investments in batteries. But in the famous words of George W, "can't fool me again". As soon as there are too many batteries and the grid companies are not making enough money, they will introduce fees to have the batteries, or increase connection fees.
With 3 hours of free power, a 15kW inverter and a 42kWh battery, I could almost do away with my solar panels and just survive of free grid power. I do have a 15kW solar panel set up, but I get very little from selling anything back to the grid.
I have a 12 kW inverter (single phase) and 48 kWh battery. In Australia, 9 months of the year my 16 kW of solar fills the battery and covers all needs including cooking, heating and charging the EV.
In winter, I’ve been using Ovo’s 3 hours free for about a year now and that ensures the battery is filled up daily. My electricity bill returns a credit every month since I got the battery a year ago.
We already get free power between 0am and 6am, so with free power between 11am and 2pm we’ll have a whopping 9 hours of free power to charge our car and heat our water storage.
