The Performance Assessment of Wave and Tidal Array Systems (PerAWaT) project, launched in October 2009 with £8m of ETI investment.The project delivered validated, commercial software tools capable of significantly reducing the levels of uncertainty associated with predicting the energy yield of major wave and tidal stream energy arrays. It also produced information that will help reduce commercial risk of future large scale wave and tidal array developments.
This deliverable focuses on the large-scale changes to the tidal hydrodynamics from the extraction of energy using tidal stream turbines. Large scale in this context means at larger scales than the wake behind an individual tidal turbine.The sites studied in this project are Pentland Firth, Anglesey and Bristol Channel.The report concludes that there are near field impacts (turbines cause reduction in flow), butno far field impacts (say between Anglesey and Bristol Channel). Environmental impact is outside the scope of the report
