The Commission for Regulation of Utilities (CRU) was assigned responsibility for the regulation of the Irish electricity sector following the enactment of the Electricity Regulation Act, 1999 and subsequent legislation. The procurement of battery storage facilities supplying the electricity grids is an operational matter for the entities involved and is not one in which the Minister has a statutory function. EirGrid, the Transmission System Operator, in conjunction with the regulatory authority, the Commission for the Regulation of Utilities, develop the primary procurement mechanisms to incorporate electricity storage onto the grid to ensure the proper functioning of the grid. The electricity storage systems including battery electricity storage systems are then developed by private enterprise. The Deputy may wish to engage with CRU or EirGrid directly regarding the issue that he is raising. Both CRU (oireachtas@cru.ie) and EirGrid (oireachtas@eirgrid.ie) have contact email addresses for Deputies should they wish to raise matters of concern such as that in the Question.
