D.7.1 LCOE Techno-economic assessment

The purpose of this document is to introduce the techno-economic model for the FLOTANT system, and the results quantifying the expected Levelised Cost of Energy (LCoE) to be achieved with this technology. This is done by considering two scales of deployment – for a pilot park (60MW) and commercial wind farm (600MW), at two locations – West of Barra and Gran Canaria, representing the range of operating conditions the FLOTANT system is designed for. The estimated LCoE values are compared with the cost reduction targets set out at the proposal stage. Comparing the key techno-economic indicators with the estimated values for a 600MW deployment by 2030 of the FLOTANT technology shows that the targets have been met.

D.7.2 Viability and sensitivity studies on FLOTANT solutions

The purpose of this document is to provide techno-economic viability indicators for potential deployments of the FLOTANT technology and perform a sensitivity study of key input parameters used in the techno-economic model. The cost estimates of the FLOTANT deployments and their sensitivity to changes in input parameters are used to assess the viability of potential projects. The considered indicators include: the Levelised Cost of Energy, the Cost of Energy, the Net Present Value, and the Internal Rate of Return. These are calculated for pilot park (60MW) and wind farm (600MW) deployments in Gran Canaria and West of Barra. Analysing the identified key techno-economic indicators taking account of the current cost of electricity in the Canary Islands and the maximum market price set within the fourth round of Contracts for Difference (CfD) for floating offshore wind in the UK, shows that the studied FLOTANT deployments would be viable at all scales at both locations. For the 600MW deployments, this is also true even in the most pessimistic scenario considered in the sensitivity study.

If focusing on the global warming potential (GW), this has been estimated to be between of 24.4-31.3 gCO2 eq/kWh. This is in the lower range of previously reported values for floating offshore wind environmental impact studies.

D.7.4 Social and socio-economic assessment
