Ireland
Electricity Regulation Act, Number 23 of 1999
The functions and duties of the CER have been altered and expanded significantly by legislation transposing EU directives into Irish law and the introduction of new primary legislation, including the Energy (Miscellaneous Provisions) Act 2006, Electricity Regulation (Amendment) (Single Electricity Market) Act 2007 and the Petroleum (Exploration and Extraction) Safety Act 2010.
These pieces of legislation have given the CER powers in relation to the all-island Single Electricity Market (SEM) and they have also given the organisation safety-related responsibilities in the energy sector.
