Joint Oireachtas Committee on Climate Action

Energy Challenges: Discussion

Mr. Jim Gannon:

That is no problem. The decision on data centres effectively gave the system operators, ESB Networks and EirGrid, a framework by which they should assess new connections. That framework asked them to seek flexibility. That flexibility could be provided by any means. It could mean simply turning down operations or using batteries. In fact, batteries could be used to provide an uninterruptible power supply while also, perhaps, providing service to the grid. It could also mean backup on-site generation. The idea was to look at all of the options available but it was for the data centres themselves to explore what those opportunities might be and to choose which of them to exploit. From discussing the matter with some of the data centre operators, we know that they were certainly looking at batteries. They were telling us that they were considering natural gas for their developments but would consider conversion to hydrogen down the road because their internal environmental, social and governance, ESG, targets require them to have a pathway in place for themselves. The decision was agnostic as to how flexibility was to be provided, although it did seek flexibility and was focused specifically on security of supply.
