Abstract
In considering the grid connection of ocean energy devices, and in particular, the connection of large offshore arrays, there are a number of technical and non-technical challenges that need to addressed by wave energy device developers. As device developers approach pre-commercial operation, grid connection factors will become increasingly significant in both technical and financial terms. In this paper some generally applicable technical and non-technical challenges are examined. A grid connection costing case study in the Irish context is performed as a practical indicator of these issues.
