Power generation in Ireland is carried out by ESB Power Generation (ESB PG) as well as by a number of independently owned power stations.
These stations generate electricity from fuels such as oil, coal and gas, as well as indigenous fuels including hydro, wind, peat and biomass.
To connect to the electricity network, a generator connecting must hold an Authorisation to Construct or Reconstruct a Generating Station and a Generator Licence. The CER is responsible for assessing and for granting or refusing to grant these permits. The conditions imposed in the Authorisation and in the Licence must be met by the generator and compliance is monitored by the CER on an ongoing basis.
