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

Here's what they have to say.
“The service from Axle has been brilliant. Even when a few small issues popped up, they were responded to and sorted right away. … I love what Axle are doing—VPP is definitely the way forward!”
Neil Goodman, NorthantsGivEnergy owner “Axle VPP really complements my Fox ESS solar and battery system, providing an extra source of revenue for my exported electricity. … Highly recommended!”
Steve, GranthamFox ESS owner “I love being part of Axle! It's great to help balance the grid and reduce the need to fire up dirty power stations when demand is high, and getting paid for doing it is a very nice bonus! The whole experience has been excellent too.”
Simon, Scottish BordersSolarEdge 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! … Keep up the great work Axle team.”
Ian, LancashireSolaX owner “After my inverter company went into administration, I was worried about my investment in solar. Axle Energy stepped in, kept everything running, now earns me at least £10 a month from export.”
Vishal, BristolGivEnergy owner “I have been involved with Axle, nearly from the outset, and so far have participated in 19 events with my Solax equipment. … I have received advance warning of every event, each also started and finished in the announced time. Payments received with the same punctuality.”
David, East SussexSolaX owner

Frequently Asked Questions
We pay £1 for every kWh your battery exports during a grid event, so a bigger battery that starts an event well charged earns more. Events run 3 to 6 times a month depending on grid conditions, and we pool earnings across the VPP so you get at least £10 a month even in a quiet one.
