Drivers of electric vehicles have changed their routine and behaviour since facing the prospect of paying to boost their battery at a public fast-charging point.
Prices were introduced in November for general use of the fast-charging network – as well as levies for anyone who is hogging a charging slot.
Since then, according to the ESB, there has been a fall-off in energy used because fewer people are using them.
A spokeswoman told the Irish Independent there had been “a decrease in energy consumption” across its fast-charging network since pricing kicked in.
She also claimed the overstay (hogging) fee is freeing chargers for those who need a quick top-up for driving longer distances – which is what they are there for.
The ESB introduced pricing for use of the 50kW fast chargers on November 18.
It is estimated that it costs an average of €4.30 to boost a battery’s range by 100km.
