E.ON customers have been invited to save electricity tonight and earn some cash in the process.
The energy supplier has been working with the National Grid to allow customers to reduce their bills and be paid for using less energy at certain peak times. Tonight, the National Grid will run a live service of its Demand Flexibility Scheme (DFS) which hopes to reduce strain on Britain's electricity by reducing demand.
Between 5pm and 6pm, energy customers taking part in the scheme are being asked to not use electricity. For E.ON customers, a personal target will be given based on their daily usage - customers who hit this target will receive credit to their E.ON next account.
