The Wave Energy Converter (WEC) System Demonstrator Project launched in February 2013 to accelerate the development and commercialisation of WEC systems capable of becoming cost competitive with other generation forms. This project conducted design and economic analysis, focusing on ways of implementing step-change innovative technical solutions.The long-term viability of WEC technology is dependent on the sector becoming commercially competitive with other low-carbon energy sources as quickly as possible through the significant reduction of energy delivery costs. This requires improvements in aspects such as capital cost, deployment & retrieval costs, survivability, technical performance (e.g. energy extraction), and operations & maintenance costs.This is the original call for proposals
