Tesla Powerwalls Soon Arriving In Australia & Netherlands
Originally published on Solar Love.
Over 1.3 million households in Australia have rooftop solar power, so it only seems reasonable that Tesla has chosen this country as one of the first that will receive its 7-kWh Powerwall home energy storage systems. They could be available as early as December of 2015, though it had been predicted they will begin arriving in 2016.
A startup named Reposit Power based in Canberra is working with Tesla to distribute the Powerwalls. The company also has created technology that integrates solar power with energy storage and it can sell stored electricity back to the grid to make money. Reposit calls the technology an energy storage and trading system.
“The idea is to buy from the grid when prices are lowest, consume as much of your own solar as possible, and occasionally sell to the markets when prices spike. This will reduce or get rid of your power bills,” said Reposit director Dean Spaccavento.
The potential to sell electricity back to the grid is intriguing: could you make enough to cover the cost of the battery system by selling electricity? If it was possible, how long would it take?
The growth of energy storage is significant for a number of reasons, but perhaps none is greater than the ability for a whole country to shift away from fossil fuels. “Australia could reach that 50% target, it just requires well-designed policies and markets that allow a transition from centralised, large-scale fossil fuels to efficient but variable renewables. Storage is a key part to make that happen. The beauty of renewables is that once you’ve managed the capital cost, there is no fuel cost. There’s an energy security there you don’t get with fossil fuels,” explained sustainable energy expert Professor Anthony Vassallo.
Also just announced, in the Netherlands, Eneco will be the first Powerwall supplier.
Tesla obviously makes great cars, but it seems that because the Powerwalls are priced much lower, they could sell in greater volume, and Tesla’s brand recognition would only increase.

It’s a mystery to me why Eneco starts this pilot. There is no off-grid market in the Netherlands and the difference in high- and low tariff just about pays for the charge losses.
The grid is very reliable and has free net metering in the law at least until 2020.
So for the coming 5 years, there is no business case at all
Wonder if the Tesla assembly resourc: for their model s is
a factor?
I second that.
Just as information for the non-Dutch: Most people in the Netherlands have just one tariff. You can however apply for a second cheaper night tariff. To get this a separate meter is installed and you monthly fixed fee goes up. So you already have to have quit a lot of night use to make up for the increased monthly fee. Making additional cost buying a powerwall + the storage losses makes it even less attractive.
Most meters in the Netherlands (with or without day/night option) are being replaced with smart meters at a fast pace. Next year smart meter settlement becomes available so you could do more complex steering with the Powerwall. I do however think that a lot of people like the self consumption aspect and maybe pay a premium for this even though there is no business case.
