Axle links thousands of home batteries into one virtual power plant. When the grid needs power, they export together and you get paid.

Export during grid events
You get paid
How much can you earn from a Sigenergy battery?
We pay £1/kWh for every unit your Sigenergy battery exports during a grid event, and at least £10 a month even when the grid is quiet.
Events depend on grid conditions in your area, so earnings vary month to month. Payments stack on top of any export tariff you already have.
Millions paid out to battery owners
Here's what a few of them say.
Sigenergy owner“Been with Axle a couple of months now. Sigenergy battery system. Usually make around £8.50 per event which is usually 1 hour. … Axle take control of my battery during the event & after they switch it back to my normal program. Great way to increase our ROI. Seamless & hassle free. Money is in the account 72 hours after the event.”
Sigenergy owner“Axle Energy is a non-brainer. If able to sell stored battery power at £1 per kWh, why wouldn't you? It took a little bit of getting used to and sorting, but Axle are great with communication. They have always got back to me with clear answers or a way to solve any issues quickly and personally.”
SolaX owner“Axle has been a game changer for me. Where else can you get paid £1 per kWh during grid events. A guaranteed £10 per month. And you don't even need to change supplier! We asked for more events and you've delivered on that front too. Keep up the great work Axle team.”
