Performance Assessment of Wave and Tidal Array Systems (PerAWaT), a project led by Garrad Hassan, and including EDF Energy, EON, the University of Edinburgh, the University of Oxford, Queen’s University Belfast and the University of Manchester will develop a series of models to predict the performance of wave and tidal stream generator arrays.

“Although the UK has huge marine potential, investment is being held back by uncertainty about the overall costs involved and the potential returns on investment in wave and tidal technologies,” said ETI Chief Executive Dr David Clarke. “This project will deliver greatly improved modelling tools to provide more accurate forecasting of energy yields and reduce the uncertainty and investment risk faced by project developers when planning large scale wave and tidal energy schemes.”

Garrad Hassan Marine Renewables Group Leader Dr Robert Rawlinson-Smith added: “Deployment of large scale arrays of marine energy conversion devices will only occur when project developers have sufficient confidence in the return on their investment.

“This project will both establish and validate numerical models capable of predicting the performance of wave & tidal energy converters (WECs and TECs) when operating in arrays. Once established, the models will enhance levels of confidence in the design of WEC and TEC arrays and therefore accelerate their large scale deployment. “

There is currently no software package or validated method of estimating the average annual energy production of a wave or tidal stream energy farm.
