Short notice events

Most Axle events are scheduled a day in advance. Occasionally the grid needs support at shorter notice, so we run events at shorter notice too.

A short notice event works just like a regular Axle event. Your battery exports to support the grid for a set period, and you earn £1/kWh for the energy it exports. The only difference is the warning: you'll typically hear at least 2 hours before the event starts. Sometimes these events last 30 minutes rather than a full hour.

Many short notice events, though not all, are Demand Flexibility Service (DFS) events. DFS is a scheme from Great Britain's electricity system operator that rewards households for shifting their electricity use when the grid is under pressure.

DFS events are usually called on cold, still winter evenings, when demand is high and wind output is low. Because they respond to grid conditions on the day, they come with less notice than our usual events. Axle takes part for you, so there's nothing extra to sign up for beyond opting in below.
