In late 2014, Marine Energy Pembrokeshire carried out a survey of the marine energy industry in Wales. The purpose was to calculate the economic contribution of the sector to date, to understand future development plans, and what this could potentially contribute to the low carbon economy in Wales. The analysis covers wave, tidal stream and tidal range energy. Already in Wales, technology and project developers have spent £34.5 million, directly creating over 99 person years of employment, rising to 174 person years when including Welsh academic research. This contribution increases, when total gross value added effects are considered within the wider supply chain and demonstrates the important contribution the sector has already made to the economy.
