Joint Oireachtas Committee on Climate Action

Renewable Energy - Wind, Solar and Biogas: Discussion

Mr. Robert O'Connor:

I thank the members for their questions. I will try to respond as quickly as I can to the two-part question about the number of turbines needed to generate 22 GW of electricity. We are not a developer and that is not our number. Given the scale of turbines, we benefit in some ways from not having deployed them over the past five, ten, 15 or 20 years. At an output of 20 MW per turbine, it would take around 1,100 turbines to provide that very large output. That would be part of a European network. There have not been any significant studies of the cost, but I would look at our near neighbour, the UK. The strike price for offshore wind energy in the most recent auctions was £39 and €44 per MW hour. If we can get our act together at scale, we have the opportunity to plan development zones producing 3 GW, 10 GW or 22 GW. As part of a network, these would allow us to achieve prices like that for the consumer.
