Eir Grid - Role

Role

EirGrid's primary purposes are the daily management of the Irish national grid, the operation of the wholesale power market, and the development of high voltage infrastructure to serve Ireland's economy. The high voltage transmission system has been likened to "motorways for power" or "broadband power" providing electricity in high quality and in bulk to all regions. Transmission is seen as a key factor in facilitating inward investment by bodies like the Industrial Development Authority (IDA) and the development body Forfas. It is also seen as critical to increased renewable energy by organisations like Sustainable Energy Ireland (SEI) and the Irish Wind Energy Association (IWEA). EirGrid is currently developing a large number of major transmission projects. It is working with the regulator in line with Irish Government policy to develop a second major transmission line to Northern Ireland and a 500 MW East West Interconnector linking the Irish power system to Great Britain. EirGrid will own that interconnector after it is developed, under the Irish Government decision.

EirGrid has its own separate board and is regulated by the Commission for Energy Regulation (the C.E.R.) and its shares are held by the Irish Government. EirGrid is responsible for balancing electricity consumption and generation, for the safe, secure and economical operation of the power system, and for the planning and development of the Irish power grid. Under the Single Electricity Market, EirGrid operates the wholesale power market on the island of Ireland with SONI System Operator of Northern Ireland (SONI), which it now owns. More information on the functions of EirGrid, along with graphs of electricity demand/wind generation output updated every 15 minutes, are available on its website www.eirgrid.com. Information on the Single Electricity Market Operator (SEMO) is also at that website.
