The ESB is raising rates by up to 52% for using its public electric vehicle charging stations.
The additions will start on December 20.
The company has increased the fees twice so far this year.
The company acknowledged in a notification to customers that the price increase would be unwelcome news for customers, particularly at this time of year.
“We want to reassure you that we have done our very best to maintain prices by absorbing the continued increases in the wholesale energy market over the past few months,” it said.
“Unfortunately, sustained higher wholesale energy costs throughout Europe means that we continue to experience a very substantial increase in the cost of wholesale electricity, which we must reluctantly pass onto our customers.”
Customers who pay as you go will see a 50% increase in the cost per kWh for standard and fast chargers and a 48% increase for high power units.
Customers who have memberships will only pay 49% for a fast charger, 46% for access to a high-power charging point, and 52% for standard chargers.
The monthly membership fee remains unchanged at €4.79.
The unit rate for drivers on for fleet charging plans will also increase to 48.4 cent per kWh for standard, 55.7 cent for fast and 58.6 cent for high power.
It is the second such increase this year by the company. In April it announced that it was putting up the unit rates charged for use of the public points by up to 53%.
“We are determined to continue offering the best value we can for customers and will keep our prices under constant review in the coming months,” the company said.
The increase is the result of more and more people switching to electric motoring.
According to the Central Statistics Office, 22% of all new cars that received their first licence during the first ten months of the year were electric or plug-in hybrid cars, up from 16% during the same time period in 2021.
