One electric car driver has managed to knock hundreds of pounds off his energy bill by using his car like a giant battery and selling power back to the National Grid

A savvy electric car owner has cut his energy bills to almost zero – by selling power back to the National Grid.
With energy bills rising, and due to hit almost £3,000 in October, many households are trying to work out ways to bring their energy costs down.
One driver, Paul Kershaw, 51, managed this in a most unusual way – by charging his electric car using cheap off-peak energy, then selling it back to the National Grid at peak times for a profit.
By doing this, Paul has been able to make enough money to cover the cost of rising energy bills.
Paul, who lives near Cambridge, said: “It has cut my energy bills almost to zero.
“It’s taking away a lot of the anxiety about bills going up by 300%. Last year I paid £7.50 for electricity per month.”
Paul made the saving by talking part in a ‘vehicle to grid’ trial between energy firm Ovo and software company Kaluza.
The scheme works because electric cars are basically “a massive battery on wheels”, as Paul puts it – and can store power.
Paul does not use his car much, meaning his vehicle’s battery is storing power he doesn’t need.
“I only drive a couple of miles a day, and the rest of the time it’s just sitting there on the driveway, depreciating in value,” Paul explained.
When Paul plugs his Nissan Leaf in to charge up during off-peak times, the Kaluza app works out exactly how much energy he needed for his car and how much he could sell back to the grid at peak times.
That power is then sold back to the National Grid when it most needs it – and when power is most expensive.
Paul averaged around £93 a month charging his car – but made £164 selling power back to the grid.
But not every electric car driver will be able to do the same thing as Paul – at least, not right away.
Selling electric car power back to the grid requires a special charging box to be installed at your house or wherever you keep your car.
Ovo did this for free for Paul, and let him keep the box.
But otherwise these boxes cost from £750 to several thousands of pounds – though the cost is expected to fall as the technology becomes more popular.
Another requirement is that your electric car must have a type of charger called CHAdeMO – currently only common in Japanese electric cars.
Around 330 drivers took part in the two-year trial.
Paul also has solar panels fitted in his property – and has sometimes made more than £200 a month by selling power from those too.
Last week The Mirror reported grants for new electric cars worth up to £1,500 have been scrapped.
Drivers could previously claim up to £1,500 towards the cost of a plug-in car costing below £32,000.
The automotive industry and motoring groups criticized the decision.
