Joint Oireachtas Committee on Communications, Climate Action and Environment

ESB Networks: Discussion (Resumed)

Ms Claire Quane:

We know what SF6 equipment we have and which equipment has the SF6 gas in it. We are constantly improving that. The old switch gear from Moneypoint can be seen in the first picture provided. As Mr. Hayes stated, we de-energised that in early June. The last of the circuits have gone into the new switch gear and the next stage now is to decommission the old switch. The new switch gear being put into Moneypoint can be seen in one of the other pictures. To give a sense of scale, the height of the old Moneypoint switch gear is approximately 7.5 m while the new gear is approximately 3.9 m. Technology evolves all of the time. The level of information we have relates to what information we got from the suppliers at the time of purchase. That improves as the technology evolves because the regulations have evolved over those years as well.
