Crown Estate reveals meteorological study

UK: The UK's Crown Estate has published a report into the validity of meteorological data used to assertain wind speeds for prospective projects in UK waters.

The 'UK Merra (Modern-Era Retrospective Analysis for Research and Applications) offshore validation' study looked at 80 years of combined data from more than 20 offshore masts around the UK.

The aim was to see if this information could be used as a substitute for installing an offshore meteorological mast at the prospective project's location.

However, the report found that Merra wind speeds were less accurate than mast measurements, although they could be used to provide estimates of wind speeds in the planning stage.

Ian Pritchard, energy asset portfolio manager at the Crown Estate, said: "The study involved the processing and analysis of wind data from over 20 offshore masts representing more than 85 years of offshore measurements, potentially representing the largest offshore validation of Merra data ever undertaken."

The Crown Estate said the reanalysis data reduces the cost and risk of offshore wind farm development.

It added it could provide a source of long-term modelled meteorological data before committing to the investment of installing a mast offshore.
