Nevertheless, the utilisation of renewable sources of energy can also have an adverse impact on the environment and our natural resources. Since 2001, OSPAR and its Biodiversity Committee (BDC) have been noting that the offshore wind energy sector has been rapidly expanding in the OSPAR maritime area. -
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. -

Application to Introduce Implicit Loss Handling on the Skagerrak Interconnector
Application to introduce implicit loss handling on the Skagerrak Interconnector The enclosed document contains the rationale for the joint application of Energinet and Statnett to introduce implicit loss functionality on the Skagerrak interconnector. The document includes a description of the applied-for method and an assessment of the expected socio-economic consequences, including distribution effects, from introducing implicit loss handling on the Skagerrak Interconnector. Further, Appendix 1-3 respectively include further description of the principle, the socio-economic analysis and analysis of intraday arbitrage. The implicit loss functionality will be implemented by the introduction of a fixed annual loss factor for the Skagerrak Interconnector. The loss factor will be adjusted annually based on historic median flow for all hours with flow for the Interconnector. The annual socio-economic gain from introducing implicit loss handling for the Skagerrak Interconnector is estimated at approximately EUR 0.9 million for Norway and EUR 2,3 million for Denmark. The title and thus the scope of Annex I to Regulation 714/2009, “Guidelines on the management and allocation of available transfer capacity of interconnections between national systems”, support the Annex having a substantial legal significance of its own. For example, the Annex may provide a legal basis for introducing methodologies of cross-border significance on an interconnector. As an EEA EFTA State, the Norwegian parliament has voted to incorporate the EU’s 3rd Energy Package, including Regulation 714/2009, into national legislation. However, the entry into force of that legislation is contingent on adoption by all EEA EFTA States, and adoption by Iceland is still lacking. -
