Abstract
From the experiences of deploying and operating a 0.5 MW tidal device, this paper will report on the technical and engineering approaches being adopted in developing both the tidal energy converter technologies and the manner in which they are being inter‐connected within these initial arrays. It will identify the challenges being faced in developing tidal current technology, site installation practices, while remaining cost effective. The paper will conclude by drawing on the conclusions of the lessons learned to date when deploying and operating utility scale tidal technology and identify the areas and opportunities where technology breakthroughs may be made in order to deliver a more cost effective, utility scale multi MW tidal array.
