Joint Oireachtas Committee on Housing, Local Government and Heritage

Housing Delivery, Service and Supply: Discussion

2:00 am

Mr. Nicholas Tarrant:

I think I do. I ask Mr. Rossiter to comment in a second, but I will make a few brief introductory remarks about the overall situation first. There has been very significant growth in the whole Drogheda area in recent years and it is probably typical of areas that have seen sustained growth in terms of electricity demand. I mentioned already about things like housing. Just to put it in context, because of electrification and the use of heat pumps in nearly all new homes, they are going in with more than twice the electrical capacity they would have done in Celtic tiger years. We are therefore using up capacity on the network both at low voltage, but also at the high voltage substations like Drybridge, in a way that is accelerated. There are also wider targets for electrification of transport like EV charging and other areas, so there is very significant demand. Back around Christmastime we lowered the threshold above which any connection offers above what is called 100 kVA have to go to our central planning team to review to see what work is going to be required to enable a connection. Obviously something like 7,000 new homes is a very significant electrical load. What that could mean for us is investment and sometimes this investment takes a number of years to deliver because substations like Drybridge are multiyear projects to deliver if you are, say, replacing them.

On the specific point about the transformers, which I ask Mr. Rossiter to comment on, we have transformers that have a certain capacity inherent in them because of their design and when they were installed back when the substation was built and there is the potential to upgrade those transformers.
