Why do we have to pay another PSO Levy?
The PSO levy is charged to all electricity customers. It is designed to support the national policy objectives of security of energy supply, the use of indigenous fuels (i.e. peat) and of renewable energy sources in electricity generation. Specifically, the proceeds of the levy are used to recoup the additional costs incurred by ESB and other suppliers in having to source a proportion of their electricity supplies from such generators. 
Peat is not a renewable resource and we should not be subsidising any use of it as a source of energy.
We have massive offshore gas reserves which we have practically given away to multinationals.
The PSO is just another bad tax just another bad tax.
