DNV to validate RWE's data findings

RWE & DNV have agreed on a scope to conduct a study assessing the impact of far wakes in offshore wind. The scope of the study asks DNV to validate the effects that RWE experts have identified. RWE models predict that large clusters of offshore wind farms could have far-reaching wind-shadowing effects, impacting wind yield of future offshore farms.

RWE reviews its methodology and approaches to wind energy yield modelling on an regular basis. RWE claims it has developed a good understanding of these long-distance 'cluster wake effects'. The preliminary model from RWE forecasts that these could have an impact up to 200 km or more and cause the energy yield in the wake areas to be reduced, in certain cases, by over 10%. This could have possible implications on future offshore development projects in Europe, for example in the German North Sea.

RWE experts plan to hand off their data to the independent energy expert and assurance provider DNV to validate the initial modeling results. DNV will independently carry out data analysis on RWE data and perform CFD modelling to review the RWE findings. The study aims to provide first results of DNV in April to reflect on the potential losses.

While the buildout of large offshore wind clusters will still take many years to materialise, the effects would already influence the economics of projects that are to be auctioned by governments in the near future.
