Treasurer Josh Frydenberg says Labor’s plan to dramatically increase the number of electric cars in Australia means the energy grid needs strengthening.

Dramatically increasing the number of electric cars in Australia will need significant funding to strengthen the energy grid, Treasurer Josh Frydenberg says.

But he said Labor’s plan to make electric vehicles 50 per cent of new car sales by 2030 is under-developed.

“There’s going to be more demand on the grid from some of these types of reforms,” Mr Frydenberg told reporters in Canberra on Thursday.

“They haven’t costed the backup and storage that’s needed, they haven’t costed what the impact on the change in the existing energy mix is.”

Labor’s ambitious target would be a dramatic increase on current electric vehicle sales, which make up just 0.2 per cent of Australia’s market.

But the party has already been forced to change part of its policy, which originally required car dealers to lower the average emissions of the cars they sold.

Instead Labor will require manufacturers to meet vehicle emissions standards.

“Every other country in the world with emissions standards regulates this through manufacturers, not dealers,” Greens senator Janet Rice said.

“This is also what the experts, including the Climate Change Authority, have always recommended.”

Labor has promised to build a network of charging stations around Australia to encourage drivers to buy electric cars.

“Australia is way behind the game on electric vehicles. I mean, every comparable country is way ahead of us,” shadow treasurer Chris Bowen told 3AW on Wednesday.

Motoring body the NRMA is calling for a ban on the sale of new petrol and diesel cars as early as 2025.

It’s started building its own network of charging stations, with 10 already built and 30 more underway.
