Erik Zigterman is involved in the Dutch off shore wind development through strategic studies and environmental impact assessment of spatial plans related to offshore wind.


Cost reduction study of far shore coordinated wind energy development


Far shore offshore wind projects are assumed to be more expensive than projects closer to shore. But what if far shore means large scale roll-out with all possible joined infrastructural facilities implementation and other cost saving options. The true potential Levelised Cost of Energy (LCoE) of large scale coordinated far Shore Wind Power has so far not been well addressed.
In the study for the Dutch TKI Offshore Wind Royal HaskoningDHV has brought market leaders together to establish a common and shared understanding on the potential LCoE and further cost reduction options for the future.


Most cost modelling tools do not include the full potential of integrated solutions, which are essential for determination of the true LCoE of Large Scale Far Shore Wind Power. By means of an interactive workshop in Royal HaskoningDHV’s iRoom with market leading experts from (amongst others) Dong, RWE, Siemens, Van Oord and TenneT several scenarios will be calculated in real time with different cost calculation models.

Main body of abstract

The currently largest designated area for off shore wind in the Netherlands Economic Zone is IJmuiden Ver. This area is about 7000 km2 and is about 80 km offshore of the Dutch Coast. At the moment smaller areas near the Dutch shore are being implemented in the period till 2023 as a result of the Energy Agreement in the Netherlands. But what happens afterwards? Will it still be possible to produce energy at same or lower cost as near shore? Or is it even possible to reduce costs even more. The study focusses on coordinated and integrated implementation of Ijmuiden Ver. This means that a spatial plan is made for the whole area whereby developers may tender for a specific plot.
The study assignment is to analyse the possibilities of reducing cost through coordinated large scale implementation of offshore wind in the designated wind energy area “IJmuiden Ver”. These scenarios include elements such as an energy island for (extendable) substation, save haven and O&M port facilities, large scale energy storage, coordinated planning and research, combined purchasing of inputs, different grid options, combining facilities of other off shore energy developers, reducing risks, etcetera.


The results of the study will be compared with the current cost levels by using the same cost calculation models. These results will be available by the End of February 2015 and will enhance the debate on cost reduction.

Learning objectives
The study will provide input in the Dutch national debate on offshore wind.
