Mr. Martin Finucane:

They concerned the economies of scale required to keep a turbine blade factory going 365 days a year, even with a market as large as the UK. There are several suppliers in Europe. Turbines of different sizes are needed depending on the waters in which they are deployed. It is difficult for a single manufacturer to supply the entire market. The choice of supplier is a commercial decision for development companies. These are very large machines. The diameter of the blades is longer than the pitch in Croke Park. Given their scale, these turbines are not manufactured or moved easily.
