Responsibility for the regulation of the electricity market is a matter for the Commission for Regulation of Utilities (CRU) which is an independent regulator, accountable to the Oireachtas and not to me, as Minister. The CRU was assigned responsibility for the regulation of the Irish electricity sector following the enactment of the Electricity Regulation Act, 1999 and subsequent legislation. It is a function of the CRU to regulate the electricity market, including the matter referred to in the Question. CRU has a dedicated email address for Oireachtas members, which enables them to raise questions on general energy regulatory matters to CRU at oireachtas@cru.ie for timely direct reply. Data on the breakdown of prepay electricity meters, by county is not held by my Department.
