Planning Challenges in Offshore Renewable Energy: Discussion

2:00 am

Mr. Paul Kelly:

In relation to fixed technology versus floating technology, the reason the economies of scale for offshore wind have become affordable is because there is a mature supply chain for the foundations for the turbines. From a floating perspective, the view of our members is that the industry has not settled on the optimum floating mooring system, so it has not been able to mature the supply chain for the mooring system and floating will continue to be more expensive than floating until the supply chain settles on what the most cost-effective mooring system is. There are some prototypes and early and pre-commercial stage floating wind farms starting to connect to the grid but from a cost perspective, fixed technology continues to be the gold standard for reliability and supply chain.
