Project to increase windfarm energy yield
23 May 2013

Independent UK company, the Carbon Trust, unveiled its latest research project on Tuesday, designed to help cut the cost of offshore wind power by increasing the energy yields from Round 3 wind farms.

The new £2m wake effects measurement project will provide detailed measurement data to the wind industry to help better understand how the wind behaves in complex situations offshore. This will help the industry to improve prediction accuracy, reduce financing costs and optimise layouts at Round 3 windfarms located up to 290km from the UK coast.

The wakes effects measurement campaign project is part of the Carbon Trust's Offshore Wind Accelerator, a world leading industry collaboration with nine UK wind farm developers to identify and commercialise a series of innovations which can dramatically reduce the costs of offshore wind.

Specialist wakes monitoring equipment has been installed on the Rodsand 2 wind farm in Denmark and will measure wakes passing through the wind farm for at least six months. Data gathered from the project will help improve specialist software enabling developers to better predict how the wind will flow offshore to enable them to develop better and more efficient designs and layouts which in turn will increase the energy yields from offshore wind farms and in turn improve the economics of the offshore wind projects.

Commenting on the new research project Phil de Villiers, head of offshore wind at the Carbon Trust said: "Bringing down the cost of offshore wind is an absolute priority for the industry. We believe that industry collaboration on key innovation projects that offer scope for dramatic cost reduction is the best way to go.

"The new wakes effects measurement campaign is very exciting as it will address the shortage of data that has constrained the development of wake effects models for offshore wind. It offers potential to increase energy yields from offshore wind farms and also offer financiers greater certainty on the economics of the projects. We are confident that the data we collect will have a dramatic impact on the future of offshore wind power, for the better".

The project is also critical to help open up debt financing for the construction of Round 3 projects in the UK. At present no UK offshore wind farm has been built with debt finance, in part because of the uncertainties around predicting the energy outputs from wind farms offshore. This project has added importance, as by offering greater certainty on energy yields it will help de-risk projects as they seek debt financing. The project may also result in the layout of offshore wind farms looking very different in the future to how they look today. The project will be of particular value to the 32GW of Round 3 projects as they move into detailed planning phases.

Brian Gribben, technical manager at Frazer-Nash, which are lead technical consultants on the wake effects project said: "We are pleased to be able to apply our significant experience in aerodynamics and wind engineering to such a large scale Carbon Trust led project especially as it has the potential to significantly benefit the industry".
