Marine Renewable Energy Strategic Framework Technical Addendum Report by RPS to the Welsh Assembly Government March 2011 Stage 3 Technical Addendum Executive Summary S.1 The Marine Renewable Energy Strategic Framework (the MRESF) is a three stage project being undertaken by RPS for the Welsh Assembly Government. Stage 1 of the project was undertaken in 2008 and included a detailed literature review and consultation, aimed at understanding the existing situation as applicable to Welsh waters. Stage 1 included issues such as current understanding of the baseline environment, knowledge of potential impacts associated with wind, wave and tidal stream developments and aspects connected more directly to the renewables industry, such as device requirements and existing constraints on consent and development. S.2 The project is currently progressing through Stage 3 and due for completion in 2011. The work undertaken during Stage 1 formed the foundations on which Stage 2 and 3 have been developed, however due to the rapid development of the industry and the degree of research currently underway, some aspects of Stage 1 could now be considered dated. To ensure the project remains contemporary at the time of completion (end of 2010; publication end of Q1 2011), the current report has been prepared, specifically to investigate potential changes, updates and additions in the following areas: Legislative requirements; Baseline data (covering Welsh waters); Increase in scientific certainty (understanding of the potential impacts of wind, wave and tidal stream from a global perspective); Updates to the potential areas of wave and tidal stream resource identified in Stage 1; and Continued liaison with projects with a degree of overlap. S.3 The current report has been prepared as a Technical Addendum to the work undertaken in Stage 1 (RPS, 2008) and is accompanied by a number of reports completed during Stage 3 (WAG 2010a and 2010b; WAG 2011a and 2011b).
