Energy company AGL has revealed that it will soon offer electric-vehicle owners a new charging deal at a cost of $365 per year, billed by the company's CEO Andy Vesey as an "all you can eat" offer.

Vesey announced the plan at the Australian Energy Week conference in Melbourne and confirmed a launch date of November 1, although full details are still to come.

“If you’re an AGL customer, or become one, then we will provide charging for electric vehicles, $1-a-day, all you can eat,” Vesey said.

The offer is understood to be part of an effort not only to win more customers, but, crucially, to build base load on its generators. Vesey told the conference that power supply in Australia "way exceeds demand" and that "clever thinking and leadership" is required.

Speaking with CarAdvice today, AGL communications manager Karen Winsbury said that the new product is also about driving the adoption of EVs.

"It's not in response to battery technology, this is about encouraging EV use. As an energy company, it's about how people can use our product, electricity. We have a very big renewable fleet, we're the largest renewable [energy] company in Australia, so it's important for us that we're encouraging our customers into cleaner sources of energy and we're investing into that ourselves," Winsbury said.
