Joint Oireachtas Committee on Climate Action

Engagement with the Commission for Regulation of Utilities

Mr. John Melvin:

These are all new data. They are all fresh and must be considered and understood. In the run-up to Christmas, EirGrid reported that domestics were visibly using less. Every single piece helps. In some of the larger users, there was a visible dip on particular days between 5 p.m. to 7 p.m. Both of those signals helped. It is important to understand that, for carbon reasons, this will be a bigger part of our lives as time goes on. For example, during the summer in California, the TSO issued an alert that things were very tight because air conditioning was on. There was such a significant response that the TSO moved from a risk of not just alert but emergency back to just alert, but it is reported that it saved the system in California this summer. Similarly, on the French system, customers get alerts to tell them today is tight, to defer what they can until later or avoid using what they can. That type of mass public participation is vital and visible in other jurisdictions. It is part of the piece the ESBN will be working on.
