    Appendix 6.1 Long list of cumulative projects considered within the EIA Report GoBe Consultants Ltd. March 2018 List of Cumulative Appendix 6.1 Projects 1 Firth of Forth and Tay Offshore Wind Farms Inch Cape Offshore Wind (as described in the decision notices of Scottish Ministers dated 10th October 2014 and plans referred to therein and as proposed in the Scoping Report submitted to MS-LOT in May 2017) The consented project will consist of up to 110 wind turbines and generating up to 784 MW situated East of the Angus Coast in the outer Forth and Tay. It is being developed by Inch Cape Offshore Windfarm Ltd (ICOL). This project was consented in 2014, but was subject to Judicial Review proceedings (see section 1.4.1.1 of the EIA Report for full details) which resulted in significant delays. Subsequently ICOL requested a Scoping Opinion for a new application comprising of 75 turbines with a generating capacity of 784 MW.

The openness and transparency of the UK power market have made it one of the most attractive destinations for overseas investors including strategic investors such as major utilities as well as infrastructure funds and other financial investors. Similar to many other markets in the world, the UK power market is going through a transition towards a cleaner energy mix. The UK will phase out coal-fired power plant by 2025 and offshore wind power is playing an increasingly important role in delivering the low carbon energy mix.

Kyle Martin, LCP Expert information for all those invested in the UK’s energy future REPORT Labour public ownership plan could create hundreds of local energy groups The Labour Party has put forward a programme for a bigger public role in energy supply that includes both national and regional authorities to set policy and could result in hundreds of local energy agencies. It promises, in ‘Bringing Energy Home’, that the change is not a return to “the distant bureaucracies of the 1970s”. The policy will start with a National Energy Agency, set up on the institutional base of National Grid, which will have duties over both decarbonisation and social objectives. It will own and operate the transmission system and will take over some of Ofgem’s functions. It will also be able to borrow to fund system extensions, including owning and operating storage. Regional energy agencies, based on distribution network operators’ areas, will have similar responsibilities within their areas and will also be able to take action over energy efficiency, regional industrial strategy and new infrastructure such as vehicle charging networks.

  • Assessment of Vessel Requirements for the U.S. Offshore Wind Sector
    Assessment of Vessel Requirements for the U.S. Offshore Wind Sector Prepared for the Department of Energy as subtopic 5.2 of the U.S. Offshore Wind: Removing Market Barriers Grant Opportunity 24th September 2013 Disclaimer This Report is being disseminated by the Department of Energy. As such, the document was prepared in compliance with Section 515 of the Treasury and General Government Appropriations Act for Fiscal Year 2001 (Public Law 106-554) and information quality guidelines issued by the Department of Energy. Though this Report does not constitute “influential” information, as that term is defined in DOE’s information quality guidelines or the Office of Management and Budget's Information Quality Bulletin for Peer Review (Bulletin), the study was reviewed both internally and externally prior to publication. For purposes of external review, the study and this final Report benefited from the advice and comments of offshore wind industry stakeholders. A series of project-specific workshops at which study findings were presented for critical review included qualified representatives from private corporations, national laboratories, and universities. Acknowledgements Preparing a report of this scope represented a year-long effort with the assistance of many people from government, the consulting sector, the offshore wind industry and our own consortium members. We would like to thank our friends and colleagues at Navigant and Garrad Hassan for their collaboration and input into our thinking and modeling. We would especially like to thank the team at the National Renewable Energy Laboratory (NREL) who prepared many of the detailed, technical analyses which underpinned much of our own subsequent modeling.

  • OTHER USERS and MATERIAL ASSETS (INFRASTRUCTURE, OTHER NATURAL RESOURCES) A3h.1 INTRODUCTION
    Offshore Energy SEA APPENDIX 3h – OTHER USERS AND MATERIAL ASSETS (INFRASTRUCTURE, OTHER NATURAL RESOURCES) A3h.1 INTRODUCTION The coasts and seas of the UK are intensively used for numerous activities of local, regional and national importance including coastally located power generators and process industries, port operations, shipping, oil and gas production, fishing, aggregate extraction, military practice, as a location for submarine cables and pipelines and for sailing, racing and other recreation. At a local scale, activities as diverse as saltmarsh, dune or machair grazing, seaweed harvesting or bait collection may be important. These activities necessarily interact at the coast and offshore and spatial conflicts can potentially arise. A key consideration of this SEA is the potential for plan elements to interact with other users and material assets, the nature and location of which are described below. A3h.2 PORTS AND SHIPPING A3h.2.1 Commercial ports UK ports are located around the coast, with their origin based on historic considerations including, principally, advantageous geography (major and other ports are indicated in Figure A3h.1 below). In 2007, some 582 million tonnes (Mt) of freight traffic was handled by UK ports, a slight decrease (ca. 2Mt) from that handled in 2006. The traffic handled in ports in England, Scotland and Wales was very similar in 2006 and 2007, differing by less than 0.5%. However, ports in Northern Ireland handled 2.5% less traffic in 2007, compared to in 2006. Over the last ten years, since 1997, inward traffic to UK ports has increased by 21% and outward traffic has decreased by 15%.
