Electricity sector in Ireland

The electricity sector in Ireland previously operated as two separate markets; Northern Ireland operated as part of the UK, and the Republic of Ireland operated its own separate market. On 1 November 2007 the two Transmission System Operators (System Operator Northern Ireland and EirGrid) established the Single Electricity Market (SEM) for the island of Ireland. The SEM has created "a gross mandatory pool market, into which all electricity generated on or imported onto the island of Ireland must be sold, and from which all wholesale electricity for consumption on or export from the island of Ireland must be purchased."[1] According to the Electricity Association of Ireland: EAI, The Single Electricity Market (SEM) is a market of approximately 2.5 million customers; 1.8 million in the Republic and 0.7 million in Northern Ireland.[2]

Electricity in the Republic of Ireland

Electricity generators in the Republic of Ireland are ESB, Airtricity, Synergen (70% ESB), Edenderry Power, Endesa-Ireland and Huntstown (Viridian). ESB owns the transmission and distribution networks.

The Transmission System Operator (TSO) is Commission for Energy Regulation (CER) which also regulates the natural gas market. The functions and duties of the CER have been altered and expanded significantly by legislation transposing EU directives into Irish law.

Electricity in Northern Ireland

Ballylumford power station provides over half of Northern Ireland's total generating capacity, and 17% of all-Ireland capacity.

Electricity is regulated by the Northern Ireland Authority for Utility Regulation. There are three power stations in the province: Ballylumford power station, Coolkeeragh power station and Kilroot power station. Northern Ireland Electricity (a subsidiary of ESB Group) owns the transmission and distribution networks.

The Single Electricity Market means that Northern Ireland Electricity carries electricity on its network in exchange for a regulated charge to the electricity supply company. As of September 2011 domestic customers in Northern Ireland are able to buy electricity from Power NI, Airtricity, or Budget Energy, with significant price differences among the three. Industrial and commercial customers are able to choose from several other electricity suppliers.

The Transmission System Operator (TSO) is System Operator Northern Ireland (SONI Ltd). SONI ensures the safe, secure and economic operation of the high voltage electricity grid in Northern Ireland. SONI's counterpart in the Republic of Ireland is EirGrid. Both of these are owned by EirGrid plc which also (through a partnership of SONI and EirGrid) acts as the Single Energy Market Operator (SEMO), i.e. runs the new all-island wholesale market for electricity.[3]
