An electric vehicle (EV), also referred to as an electric drive vehicle, uses one or more electric motors or traction motors for propulsion. This include electric cars, electric trains, lorries, aeroplane and many more.
Electric vehicles could provide an average of 6 percent of daily network balancing service requirements in Great Britain, a study showed.
By providing energy when demand is high and taking power during recharging when demand is low, electric vehicles offer grid operators a potential power backup or excess energy supply storage. This is according to a study released by British grid operator National Grid P.L.C. in cooperation with engineering group Ricardo.
National Grid reported spending £50.4 million ($82 million) in March only for balancing power supply and demand and securing electricity supply.
This made the grid operator look for alternative systems, such as demand-side management, which could bring the added value of increasing business confidence and investment in the power grid.
This includes a proposal to pay electric car owners when they decide not to recharge their electric vehicles at times of high demand. Conversely, electric cars could feed electricity back to the power grid using vehica/ -to-grid technology.
Car owners could potentially have a financial return of £50 every year, equivalent to 18 percent of an estimated annual £287 electricity bill.
While the potential revenue for each vehicle is relatively low, there is no requirement for additional investment aside from the smart metering technology, which is already mandated for future roll-out within Britain, the study said.
But the study concludes that such a system is only possible where smart metering technology is widely deployed and policies are favorable to electric car use.
The government’s commitment to slashing carbon dioxide by 34 percent, in accordance with the European Union’s 2020 target, has led to its decision of putting in £400 to support consumer take-up of electric cars. (R.F. Caronan)
