Last Monday, NSW power prices went through the roof.
A spring heatwave pushed demand up fast, four coal units were offline, and parts of the transmission network were running below capacity. Wholesale prices jumped from around $200 per megawatt hour to $23,107.
For most households, that all happened behind the scenes.
But for around 30,000 homes with batteries on Amber Electric, it turned into an opportunity. Their batteries sold stored power back to the grid while prices peaked. Amber says those customers earned about $2 million between them in two hours, or around $69 each on average.
We want to be upfront. This was a rare event, and nobody should buy a battery expecting a payday like that every week.
Wholesale pricing works both ways, which is exactly why the right battery and smart software matter.
The everyday value of a battery is still the simple one: store your solar, use it at night, buy less from the grid.
But it's a glimpse of where home batteries are heading. With the right battery, retailer and software, your stored energy can work a lot harder.
As an Amber partner installer, we'll tell you straight whether your battery, or the one you're considering, is compatible.
We've written up the full story, including what it does and doesn't mean for battery owners.
