Electric cars ‘could collapse energy grid’

ENERGY giants are warning the nation’s electricity supply could fail unless they are given the power to decide when and how electric cars are charged.

The industry fears that the mass adoption of the vehicles could put an enormous strain on the national grid.

As a result, they want the introduction of technology that means they can turn car charging systems off when demand from homes and businesses is high.

In theory, that could mean a family that leaves their car on charge overnight ahead of a long journey could find the battery cannot get them to their destination the next day.

Sales of plug-in cars have risen by 716 per cent in the last two years.

In a report published today, Energy UK the trade body for Britain’s power companies, states: ‘Electric vehicles create new electricity demand, which energy retailers, generators and network companies need to predict to ensure the energy system continues to provide reliable services to customers.’

The organisation says there is a need for Smart Charging Solutions which would spread demand. This could involve tariffs that penalise car owners with high bills if they charge at peak times.
