How Smart Meter Night-Rate Battery Arbitrage Works in Ireland
With the ESB Networks national smart meter rollout, Irish electricity suppliers offer dramatic discounts during the 4-hour night boost window (02:00 to 06:00 AM). While regular daytime peak power costs up to 38c - 40c per kWh, night-boost EV tariffs drop as low as 7.2c per kWh.
By installing an intelligent home battery (5.1kWh to 15.3kWh) paired with a smart hybrid inverter, your home charges at the rock-bottom 7.2c rate every single night—even in the dead of winter when there is zero sunshine. During peak morning and evening hours, the battery powers your heat pump, induction hob, and appliances, effectively locking in an average electricity cost of sub-10c per kWh year-round.
