The Public Service Obligation (PSO) levy is a levy imposed on electricity bills by the government that supports the generation of electricity from sustainable renewable sources like wind and solar and also our indigenous fuel, peat.


How much is the PSO Levy for business customers?

The amount of PSO you pay for your business premises is based on your Maximum Import Capacity (MIC).

from 1st of October 2020 to 30th September 2021 are:

  • PSO where MIC < 30kVA = €21.41 per month (Excl. VAT)
  • PSO where MIC => 30kVA = €2.78 per kVA per month (Excl. VAT)


Maximum Import Capacity (MIC) is the amount of space reserved on the network for any given meter. It is measured in KvA (Kilovolt Amps). Each meter is set at a different level, as set by the commissioning electrician.

Your PSO Levy is calculated by the level at which your MIC is set. Too low, you pay more PSO. Too high, you incur excess penalties. If it helps, think of it as a belt, tightened by someone else. Too tight: it’s uncomfortable. Not tight enough: you lose your pants. You should be confident that your MIC is sized for an optimum level of PSO payment.

Failure to review your Maximum Import Capacity will lead to higher energy costs.
