Unit rates are to be reduced by 13% for high-power (200kW) chargers, 12% for rapid chargers, and 8% for regular chargers.
It said that in order to further incentivize drivers to free up charge points for future drivers when they are done charging, the current one-time €8 overstay price has been changed with a more "progressive", incremental fee.
According to ESB's most recent customer poll, 76% of participants are in favour of the overstay cost.
The new overstay price schedule, which is 50 cents per minute, will start after 10 hours for regular chargers and 45 minutes for high-power and quick chargers.
Until the end of this week, high-power chargers will also accept contactless payments.
To improve the speed and capacity of the charging network, ESB has updated over 300 chargers and erected 42 multi-vehicle, high-power charging hubs around the country in the last two years.
There are already more than 1,600 public charging stations installed nationwide, with a 98% dependability rate on average.
ESB's Head of eMobility, John Byrne, announced that the firm was cutting pricing as a result of decreasing wholesale energy costs.
“We keep our prices under constant review and are committed to providing value to our customers with competitive prices,” said Byrne.
