Australia is undergoing something of an energy crisis – growing demand combined with under-investment in the electric grid has recently led to a series of embarrassing blackouts, and electric rates are soaring. South Australia has just overtaken Denmark as the place with the world’s most expensive electricity.

Of course, sunshine is abundant Down Under, and locals have been enthusiastic adopters of rooftop solar for years. In the state of Queensland, over 31 percent of homes have solar panels. However, over the past couple of years, local governments and utilities have been phasing out subsidies and incentive programs that encouraged homeowners to install solar.

The most important of these is net metering, a program by which a utility buys excess power generated by a home solar system, offsetting the cost of electricity consumed when the sun isn’t shining. The value of net metering depends on the feed-in tariff – the price that the utility pays for power fed back into the grid. A homeowner reaps the full savings of solar only if the feed-in tariff is equal to the retail rate for electricity. If the feed-in tariff is lower, then the homeowner receives a discounted rate for excess energy generated during the day when the sun is shining, but pays full freight for energy used at night.

Over the past couple of years, as Australian utilities have started to see rooftop solar as a threat to their income, they have been lowering their feed-in tariffs (the same trend is gathering momentum in the US). As Gizmodo reports, feed-in tariffs in parts of Australia are now four or five times less than the retail cost of electricity, greatly reducing the savings from solar. What homeowners need is a way to store their solar energy and be truly independent of the local power company.

Well, as it happens, just about the time that Australian utilities started getting stingy, Tesla started selling the Powerwall in Australia. Unsurprisingly, demand has been huge, with Queensland leading the way. “This is likely due to the rapid uptake of rooftop solar towards the end of the generous bonus feed-in-tariff period,” says Chris Williams, the CEO of Powerwall installer Natural Solar.

According to Williams, only 2 or 3 per cent of customers even asked about batteries prior to 2015. “Since adding Tesla Powerwall to our energy storage range, the volume of consumer enquiries for battery power and Powerwall specifically has grown to more than 95% of customers,” he told Gizmodo.

The introduction of the new and improved Powerwall 2 in October 2016 led to a further surge in demand. The new model features a built-in inverter, and it almost doubles the capacity of its predecessor, from 7 kWh to 14 kWh. As Australia’s average household electricity usage is estimated at around 16 kWh per day, the Powerwall 2 offers enough storage for many households to offset their entire electricity bills.

Some customers have done just that, and Chris Williams thinks this is just the beginning. “Mass adoption of residential and commercial batteries is already underway and considered to be the new norm,” he said. “Rarely do our customers enquire for just solar anymore, and battery power is the new must-have. Customers are [also] now commonly requesting items such as electric vehicle (EV) chargers with the intent of purchasing an electric vehicle in the future.”

GO TESLA GO…Al Gore will be pleased along with many global warming believers myself included. Al Gore was on CNN last night and is optimistic despite having Republican deniers in power.

Yes, having a positive attitude is oh so important. Even after continuous assaults the climate change non-deniers, deniers, (there is still hope), soldier on.

A positive attitude is very powerful and effective because without it you become helpless and useless.

“As Australia’s average household electricity usage is estimated at around 16 kWh per day”
Is that right? Seems really low. I use about 35kWh/day. I have a plugin EV, but still, not a lot of other electric devices.

I live in a two bedroom apartment with AC for down stairs living area and two small fan heaters upstairs for the bedrooms. I also have a 2013 Volt that I charge every day. Using about 25KWh per day.

Here in Ireland the official average is 11.5kWh/day. In reality it’s probably a little less.

I lived in the US for a few years around 2007. Your homes are really inefficient, high energy usage appliances, no geothermal heating and insulation doesn’t seem to exist.

Of course with two EVs on the road doing big mileage my home pulls ~40kWh a day… ~34-35 for the cars. But mostly at night when grid power is up to 85% wind and hydro.

Power usage in the US and Australia is often increased pretty dramatically by the use of electrical heating for hot water and space heating/cooling (done in the EU with gas). There is also a significant size difference between houses in the old world and the new world. The house I lived in when I was in the UK would probably fit in the front room of the house I live in here in Australia. Having said that the average Australian house in terms of insulation and air flow is equivalent to the average German home with a 1.5 x 0.5 m hole in it so we shouldn’t be complacent, there is plenty of room for improvement. Often the people with low (sub 10 kWh) daily consumption in houses in Australia have evaporative cooling systems and a gas connections for heating.

What?!! I’m in Canada and I average 150KWh/month, and I’m in an 1350 sq ft. house. The big difference seems to be…I have no aircon. Oh, and I have a 10KW solar system.

I think NC outer banks might be interested.

Hehehe. Sadly, the vast majority of solar PV systems don’t work when the grid goes down. Getting them to do that adds a lot of cost. But it starting to make sense now with batteries getting cheaper. The current electronics for it though are not very good & kinda expensive.

I’m in Melbourne and use an average of 6.5 kWh a day in a small all electric 55 year old brick veneer home with between 1 and 3 occupants. No electric car yet. Have to wait until early 2019 for my Model 3!

WOW! How do you use to little? Do you have a tiny refrigerator, gas appliances, and a single light bulb?

That is impressively efficient.

Oh wait! Never mind. I thought that was per month. Per DAY? That’s a lot. But I guess you use a lot of AC.

6kWh/day is alot to you? I can’t believe anyone in a normal house gets below 10.

My house has 3 bedrooms, L-shaped lounge/dinning room, kitchen, laundry, 1 bathroom & shower & toilet. In last few years I have:

– installed 4 small reverse cycle heat pump ACs in 3 bedrooms and lounge allowing zoned heating and cooling
– ripped out gas ducted heating
– added much improved insulation in roof, under floor boards and pumped into wall cavities between bricks and timber framing and plaster
– replaced most light bulbs with LEDs
– replaced old fridge with 4 star Electrolux
– replaced old gas water heater with heat pump water heater ( programmed to run from noon getting almost all electricity from my solar panels)
– disconnected from gas supply
– draught proofing
– Induction cooktop and oven
– low flow shower head

Soon to retrofit double glazing to most windows. Then will install energy efficient air pocket type blinds.

Good effort, is your 6.5 kWh per day before or after solar?

It is my total usage. I average just over 2kWh from the grid each day and just over 4kWh from the solar panels. I also export to the grid an average of 30kWh a day and get paid $0.14 per kWh feed it tariff from my electricity retailer. I have a 9.8kW pv system.

From a behavioural perspective, I ensure I turn off appliances when not in use, turn off standby appliances at the switch (or even the switchboard), only heat or cool zoned spaces that are in use, use exterior blinds on west facing windows to best advantage.

I also don’t have a clothes drier (I use a clothes hoist and the sun), don’t have an electric blanket, don’t use heating overnight, don’t have a dishwasher (done by hand).

Have you had a look at the Enphase range of products? They do little 1.2 kWh batteries that would fit very nicely into your setup. There is also a company (Globird energy) who do an electricity tariff in Melbourne that essentially has an off peak rate any time after 10pm and before 3pm. Needless to say the peak rate is eye wateringly high but it could work quite nicely for you.

I’ve got Enphase microinverters. But their batteries (or anybody else’s) don’t add up financially unless some retailer wants to pays me some good money to store some of my excess solar and release it to the grid in peak periods or when needed.

I’m with GloBird and get the $0.14 per kWh feed-in tariff from them. Because my usage is low and my exports high, the only thing that matters financially is the feed-in tariff.

We just got our July electric bill. July was very hot, most days in the 90’s, three of 100F. 501 kWh/31 days=16.16 kWh per day.

While I a yank, I am hoping that Australia gets one of the Tesla GF. Australia is loaded with Lithium and all sorts of useful minerals. Makes far more sense to manufactuer there and ship to CHina and other nations, then it does to ship ore to China.

Australia is the 1 exported of lithium ores, and in the top 5 for Ni, Co and Mn ores. We import refined oil from Singapore.

I still feel that the inverter/charger/controller electronics needed for the Powerwall are not very good. The best is from SolarEdge but it still needs a lot of work to be cheaper, easier, and better-integrated.

I’ve had a theory that Tesla has been working behind the scenes to develop their own inverter/charger/controller electronics. After all, they have people to design such things at Tesla.

Fantastic article. What has happened down here with power is just unbelievable. The best way I have heard it described is that we are “uniquely stupid” it’s not even about the environment its just total disaster. Over the last 2 years we have had a problem in every single state on the eastern sea board (Qld – price spikes, NSW – load shedding of aluminum smelter, Vic – blind panic caused by a 53 year power station closing, Tas – failure to manage water levels in dams leading to diesel generators running the state and SA – state wide black out, most expensive power in the world, load shedding and wind curtailment). Some of those states source almost all of their power from traditional sources. Australia is the 2nd biggest exporter of natural gas, yet last year we had a shortage locally. Our coal exports are the cheapest in the world yet our coal power is the some of the most expensive in the world. We have over 500 times the required recoverable renewable energy resources within range of our grid, a 1000 years worth of coal reserves, and yet we are installing diesel generators on the grid and load… Read more »

Well summarised. A lot of this has been caused over the last 10 years by climate change denying, conservative forces and fossil fuel interests who either want to live in last century or just want to keep lining their own pockets instead of serving the best interests of the Australian people.

I used to think that but I have come to the conclusion that it is actually more to do with incompetence than shady business figures maximizing their profits. Another couple of years like the last few and the power industry will be renationalised, we’re already seeing SA installing state own assets.

Well put. +1

I might add, a contested way ahead such that little action is taken by government and business (loss of investment confidence)

We have our own little ‘deconstruction of the administrative state’ going on.

There’s one really basic fault to this that the article and subsequent posters do not seem to have realised. Australian buildings, particularly roofs, are built in a totally different way to the USA. We don’t line the roof structure with pressed wood sheeting before putting shingles on. We use corrugated iron or concrete tiles on timber battens spaced the required distance apart – 900mm in the case of tin and 300mm for tiles. Before the tin/tiles go on, we generally put insulation in rolls under them. Tesla tiles would require a massive redesign in the way we build. Australia is not kown to embrace change
