Joint Oireachtas Committee on Climate Action
General Oversight of EirGrid: Discussion
Mr. Michael Mahon:
I will come in on that point. A significant amount of offshore wind is currently being built in Scotland, for example. Most of it is fixed technology rather than floating. There are a number of floating wind farms in Scotland and off the coast of Portugal. They are in the 30 MW to 50 MW, or maybe 80 MW, territory. We are looking at offshore wind projects connecting a minimum of between 400 MW and 500 MW, and rising. Several much larger projects have gone through auctions in the UK. Massive investment is required to make those technologies work. It is probably a little too early to go in on that and to ignore the fixed options that are still available, particularly on the east and south coasts. There is a significant amount more potential in that regard. We must also think of it in an Irish context. As Dr. Ryan stated, we are able to satisfy the demand we have with a lot of the fixed that has been planned. There is also the challenge relating to the lack of export potential. Although we believe we will have the export potential in future, we have to look at the Irish demand. The Irish demand is typically on the east coast. Complementing that with projects on a fixed level on the east coast probably makes more economic sense. Floating will be there, however. The price should come down each year and the technology will be more proven. There are several people looking at the west coast. The conditions there are more challenging than in some of the locations being identified in Scotland. There is a need to be able to deploy technologies they are confident will last in the wild Atlantic.
