The PSO levy is designed to support the national policy objectives of security of energy supply, the use of indigenous fuels (e.g. peat) and of the use renewable energy sources in electricity generation. Specifically, the proceeds of the levy are used to recoup the additional costs incurred by the ESB and other suppliers in having to source a proportion of their electricity supplies from such generators.

The levy is calculated by the Commission for Energy Regulation in accordance with the relevant legislation and particular terms of the various PSO schemes.
