Drivers of electric cars in Queensland will pay 45 cents per kilowatt hour to charge their vehicles starting this month, about half the cost of fuelling up with petrol.

Until now, the state government’s network of 31 electric car charging stations, located along the coast between Cairns and Coolangatta and inland to Toowoomba, has been free.

A spokesman for Main Roads Minister Mark Bailey says Yurika Energy, the sustainable energy arm of Energy Queensland, is in negotiations with a private firm partner to charge a price below 45 cents per kilowatt hour, which equates to about $20 for 300 kilometres of driving range.
