Public Service Obligation


​The Public Service Obligation (PSO) levy has been in place since 2001 and is the overall support mechanism for peat generation, for certain conventional generation constructed for security of supply purposes, and for the development of renewable electricity. The levy is designed to compensate electricity suppliers for the additional costs they incur by purchasing electricity generated by these producers.

The PSO levy is vital to enable Ireland to meet its 40% target for electricity generated from renewable sources by 2020, which in turn is important for the achievement of Ireland's 16% EU 2020 target for renewable energy.

The Commission for Energy Regulation (CER) determines the PSO levy which is a charge on all electricity customers without exception. The legal basis for the PSO levy and its method of calculation are set out in regulations made under the Electricity Regulation Act 1999. The scheme sets out that the levy applies to all electricity customers and the levy amount is reviewed annually. Further details on the PSO can be found on the CER website.
