What is the PSO levy?

What is the PSO levy?

The PSO levy, or Public Service Obligation levy, is a Government levy that is charged to all electricity customers in Ireland. The money collected from the PSO levy is mainly used to subsidise and support renewable and indigenous energy generation in Ireland.

How much is the PSO levy?

The Commission for Regulation of Utilities (CRU) sets the level of the PSO levy every year, which runs from 1st October until 30th September. 

The levy is currently €41.76 (ex VAT) or €47.40 (inc. VAT) for the 2018/19 period.

Every domestic electricity customer pays this charge.

The PSO levy on your bill

The PSO levy appears on all domestic electricity bills and can usually be seen in the bill breakdown as a line under the Standing Charge and the quantity of units for which you are being charged.

PSO levy history

Since the PSO levy was first charged in 2010, it has fallen four times - in 2011, 2015, 2018 and 2019.

The PSO levy is currently €47.40 a year (inc. VAT) for the 2018/19 period and this will decrease to €38.68 for the 2019/20 period. 

This year's decrease means that the PSO levy charge is at its lowest in six years, since the 2012/13 period.

How is the PSO levy determined?

The amount that customers are charged for the PSO levy depends on a range of factors, the biggest of which is the wholesale price of electricity.

Because the main objectives of the PSO levy are the promotion of renewable energy generation, the security of our energy supply and the use of indigenous fuels like peat, it has been determined that certain types of power generation should be protected from sharp market fluctuations.

In general, if the wholesale electricity price (also known as the SEM price) is high, less money is needed to subsidise renewable energy generation and peat burning power plants. That’s because they receive more money on the open market for the electricity they produce.

When wholesale prices are low, more money is needed to subsidise PSO schemes because they make less money on the open market.

Thus when the wholesale price of electricity rises then PSO levy tends to fall and vice versa.
