What is the PSO Levy for business customers?

The Public Service Obligation Levy (PSO) is mandated by the Irish Government and approved by the European Commission to support the generation of electricity from sustainable, renewable and indigenous sources.

The levy is calculated and certified annually by the Commission for Regulation of Utilities (CRU) in accordance with relevant legislation and all energy suppliers are required to collect this levy from customers.

What are the PSO levy rates for business customers?

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

The new PSO levy rates for businesses from 1ST of October 2022 to 30th September 2023 are:

  • PSO where MIC < 30kVA = annual rebate of €311.51
  • PSO where MIC => 30kVA = annual reimbursement of €37.82/kVA

This is the first time there has been a negative PSO. To enable the CRU to implement an enduring solution to ensure the billing and invoice arrangements could be put in place to facilitate a PSO rebate to all customers, the CRU set the PSO to zero from 1st October 2022 until 28th February 2023, and from 1st March 2023 to 30th September as follows:

  • PSO where MIC < 30kVA = monthly rebate of €44.50 for 7 months

  • PSO where MIC => 30kVA = monthly rebate of €5.40/kVa for 7 months
