Samenvatting

In this report, the details of an investigation into the e ect of the low induction wind turbines on the Levelised Cost of Electricity
(LCoE) in a 1GW o shore wind farm is outlined. The 10 MW INNWIND.EU conventional wind turbine and its low induction
variant, the 10 MW AVATAR wind turbine, are considered in a variety of 10x10 layout configurations. The Annual Energy
Production (AEP) and cost of electrical infrastructure were determined using two in-house ECN software tools, namely FarmFlow
and EEFarm II. Combining this information with a generalised cost model, the LCoE from these layouts were determined. The
optimum LCoE for the AVATAR wind farm was determined to be 92.15 e/MWh while for the INNWIND.EU wind farm it was
93.85 e/MWh. Although the low induction wind farm o ered a marginally lower LCoE, it should not be considered as definitive
due to simple nature of the cost model used. The results do indicate that the AVATAR wind farms require less space to achieve this
similar cost performace, with a higher optimal wind farm power density (WFPD) of 3.7 MW/km2 compared to 3 MW/km2 for the
INNWIND.EU based wind farm.
