To date, some 190 tidal power sites have been identified off Canada's coasts, with a total estimated capacity of 42,000 MW equivalent to more than 63 % of the country's annual total consumption. Tidal Energy Converters (TECs) deployed in arrays appear to be the most promising solution to efficiently capture this carbon neutral energy resource. Indeed, in contrast to tidal bar-rages, TEC arrays permit a higher concentration of devices without entirely blocking the tidal flow and thus avoid drastic changes in the hydrodynamics of the site while minimizing the overall cost,by allowing for shared maintenance and grid connection expenses. Whilst the tidal energy industry grows and commercial-scale TEC array projects emerge, the optimisation of TEC array becomes prudent to improve financial viability and limit environmental impacts. The very concept of TEC array optimisation covers a multitude of scopes depending on one's goals and interests. The set of levers, benchmarks and constraints would vary from the point of view of a technology developer, a project developer, a site manager, an investor, a policy maker and so on. Consequently different sets of Environmental, technical and economic parameters shall be used for different optimisation scopes.Unfortunately, being the most efficient solution does not mean it is the simplest one. As a matter of fact, TEC array optimisation may encompass numerous parameters, all inter-connected through the hydrodynamics governing the flow surrounding the considered array. Such intricate problem requires cutting-edge numerical methods in order to be appropriately addressed. A collaboration between the authors has enabled this study to move one step forward by numerically simulating both their potential hydrodynamic impacts and financial viability to help understand the leveraging importance of each of these aspects as well as potential brakes on project development, ultimately lowering the risks of project failure and thus stimulating investment.
