10 Offshore Wind plays an important role; both in its own right and if other technologies are constrained Offshore Wind is the main hedging option for 2050 UK energy mix It can provide a proven low carbon solution if the deployment of other technologies is constrained By 2050, between 20 and 40GW of Offshore Wind could be deployed Higher in some scenarios Of that 40GW, between 8 and 16GW could be TLP based floating offshore wind Scottish waters are particularly well suited to the technology It would be good if we could add semi-submersibles, spar buoys and concrete hulls to our study

11 OFFSHORE WIND FLOATING SYSTEM FEED STUDY

12 ETI kicked off the floating foundation project to access better quality wind, close to shore Our studies showed that to deliver lowest cost offshore wind we needed to access: High wind speed site Close enough to shore to Be maintainable from a shore base Avoid HVDC transmission This insight is reinforced by the results of the FEED study

13 ETI commissioned a FEED study for a TLP based system Best additionality for ETI Led by Glosten Associates Alstom 6MW turbine Objectives Understand LCOE potential of Glosten TLP technology Develop a design for a full scale demonstrator To inform the LCOE study Potential investment in a full scale demonstrator

14 Floating foundations have advantages Shore side build and commissioning TLPs Weight (compared to other floating technologies and fixed foundations) Weight is a proxy for cost Limited mooring spread, less seabed use Stable platform

15 The TLP FEED study indicates that a TLP solution could be very attractive for UK (and other) waters Actual deployment likely to be 5+ years longer than shown in this graph A paper on the UK cost study is available at

16 What next? Glosten are working to on gaining investment for a 6MW demonstrator Build compelling case for a demonstrator with key stakeholders

17 Conclusions Offshore Wind has a significant role to play in the UK 2050 energy mix Provides proven capability if other technology deployment is constrained Deployment of 8 to 16 GW of TLP floating wind (if total is 40GW) could make economic sense for the UK Potential to deliver costs at less than 85/MWh Need further work to establish cost of energy potential for each floating technology. LCOE for floating wind varies between technologies
