This document outlines the scope and requirements for projects seeking funding under the LCE-15-2016 funding action for scaling up ocean energy arrays. Projects must demonstrate a selected ocean energy technology at a pre-commercial scale and connected to the grid. They must include engineering plans, a business plan, and permits to deploy an array. An independent committee will review deliverables and approve the project to proceed. The expected impact is a cost-effective array to reduce the cost of ocean energy and attract investors, strengthening Europe's industrial technology in this field.
