AB - This study (under Phase 2 TA) is intended to build further on the main findings from the Offshore Wind Roadmap (under Phase 1 TA). It focuses on conducting a pre-feasibility study for two high potential areas for wind power development off the coast of Puttalam and Mannar provinces. The main objective of this study is to create attractive market conditions for investors and advance the development of the first offshore wind projects in Sri Lanka. The technical assistance also aims to: 1) to de-risk future project development activities, 2) to engage stakeholders and build capacity to create widespread support, and 3) to increase general knowledge of offshore wind in Sri Lanka. The technical assistance consists of several integrated assessments as follows. A constraint assessment (Chapter 2) was carried out to identify potential risks and barriers for offshore wind energy, and to identify the best potential locations for development projects. This information, along with other aspects such as realistic scales and local context, was used to develop project concepts (Chapter 3). These project concepts include information about infrastructure characteristics such as turbines, foundations, layout and the grid. Several variations were made to conduct a comparative assessment on factors such as energy yield and (economic) feasibility. Additionally, several more nationwide building blocks for offshore wind development were investigated. A port appraisal study (Chapter 4) was conducted to determine the readiness and required upgrades of Sri Lankan and nearby Indian ports, including an outlook on potential socioeconomic opportunities. The electrical system of Sri Lanka was also analysed (Chapter 5) to obtain insights on how to integrate the power from offshore wind projects into the grid, including an overview of potential grid development and including power flow modelling. An assessment of favourable market conditions (Chapter 6) was conducted, including mitigation and solution measures for commercial risks and bankability issues. Finally, stakeholder engagement and capacity building activities (Chapter 7) were conducted throughout the entire duration of the study. View the Executive Summary hereView the Full Report here
