Innovations in wind farm development are anticipated to reduce the LCOE by between 2% and
2.5% between FID 2014 and 2025, with the largest savings anticipated for projects using 4MWSize
Turbines on Site Type D. The savings are dominated by improvements in CAPEX, especially
post development, rather than in OPEX or AEP.
Figure 4.1 shows that the impact on LCOE is greatest for a wind farm using 4MW-Size Turbines
on Site Type D. The aggregate impact of innovations in this element actually increases the spend
on wind farm development marginally but, through this, reduces costs of other elements of the
wind farm, primarily the support structure and construction.
