  1. 1. Presented by: Ioan Jenkins - Development Director
  2. 2. Tidal Lagoons: 1. Harness a free and reliable source. The moon 2. Remove risk. Proven hydro turbines and civil engineering methods 3. Challenge everything. 3 years to analyse every impact and construction norm 4. Create proof of concept and systematic buy-in. The world’s first tidal lagoon with unprecedented community support How to do big and sustainable, successfully 2
  3. 3. OUR VISION
  4. 4.  Low carbon electricity: 8-10% of UK electricity, secured within a decade  Energy security: Reliable, home-grown and near continuous power supply from proven technology, lasting 120 years  Affordable energy: Lowest generation cost of all electricity for 85+ years following investment period. Lower support cost than most low carbon electricity; larger lagoons generate cheaper power  Hydro for Britain A national fleet of 6 tidal lagoons to deliver … 1 5

  9. 9. 2014 2015 2016 2017 2018 18 months of development work suggests Swansea Bay offers great potential for lagoon construction. Key ongoing work streams:  EIA – scope agreed with regulators, EIA now underway, with collaborative input from statutory consultees (including NRW and LPAs). PEIR published 4 July.  Hydrodynamic modelling – multiple lagoon shapes/sizes tested for water quality, sediment transport and sand erosion/deposition impacts  Value engineering – reduce cost of sea wall, turbine housing, construction methods  Turbine design – leading manufacturers Voith/Alstom/GE/Andritz Hydro refining specifications for low-head bulb turbines  Grid – planning consent has been achieved with National Grid & Western Power Distribution  Leasing & consents – engagement with landowners including The Crown Estate, ABP Swansea, Swansea University, St Modwen  Onshore masterplanning – maximising onshore opportunities with ABP & University Ongoing EIA, viability & design refinement

  11. 11. Planning context 2014 2015 2016 2017 2018 Planning Act 2008  +100MW offshore lagoon = Nationally Significant Infrastructure Project  Application to Planning Inspectorate (PINS) for decision by Sec. of State for Energy  Development Consent Order (DCO) combines previous separate consent procedures  DCO will comprise: lagoon structure, onshore grid connection, supporting development Marine and Coastal Access Act 2009  Marine license required for construction and dredging in Welsh waters  Issued by Welsh Govt. Marine Licensing Team (MLT)  PINS and MLT cooperate; processes run in parallel Town & Country Planning Act 1990  Apply to Swansea/NPT Councils for elements outside the NSIP above Mean Low Water, e.g. bio- fuels facility

  14. 14. Breakwater design – geotextile option Water is impounded by a wall or “breakwater” to create a lagoon 1. Breakwater comprises layered geotextiles encased by rock armour 2. Geotextiles are filled with dredged sand from Swansea Bay and then positioned around the lagoon’s perimeter 3. Rock is transported from our own quarry to the lagoon by sea 1

  16. 16. Breakwater design – quarry run option Water is impounded by a wall or “breakwater” to create a lagoon 1. Breakwater comprises bunds of quarry run with sand fill in between 2. Armour rock is placed on top (similar as for geotextile option) 3. Rock and quarry run is transported from our own quarry to the lagoon by sea 3
