Balancing services
The grid pays for quick help when supply and demand need nudging back into balance. A coordinated battery fleet can respond fast.
Your battery earns
The battery that pays you back, then keeps paying.
The electricity grid constantly needs quick help: a little stored power released at the right moment, or a little demand soaked up. Thousands of home batteries, coordinated, can provide it and get paid. That coordination is called a virtual power plant.
Every compatible battery Worpra installs is set up to earn in the background, above a reserve you control, while you keep your own electricity supplier.

Where the money comes from
Three plain-English routes
Demand-response events
At busy times, batteries can reduce pressure by discharging or avoiding charging. The value comes from reducing stress on the system.
Price arbitrage
The battery can charge when power is cheaper and use that energy when the home would otherwise import at a higher rate.
Realistic value
Bill saving and grid earnings are separate numbers.
A battery already helps by shifting solar and cheap-rate electricity into the times you need it. Flexibility earnings sit on top, and Worpra keeps those assumptions visible rather than rolling everything into one heroic figure.
The current model uses a typical annual earnings range of £120-£250 for a home battery, before survey and compatibility checks.

Supplier agnostic
Your battery, your choice.
Some batteries only become intelligent on one supplier's tariff. Switch supplier and the brains can leave with it. Worpra favours systems that keep the earning route separate from supplier lock-in.
That matters because tariffs and flexibility markets change. You should be able to move to the best deal without making the battery dumb.
No switch
Supplier choice stays with the customer.
Caveats
Earnings move, so the assumptions stay visible.
Earnings vary with grid conditions, season, battery size, tariff and scheme availability. Worpra publishes the assumptions behind the calculator and updates them when the market changes.
