  • Annex D Major Events in the Energy Industry
    Annex D Major events in the Energy Industry 2017 Electricity The foundation stone for the new ElecLink electricity connection between Britain and France was laid in February 2017. The interconnector will run through the Channel Tunnel between Sellindge in the UK and Les Mandarins in France, and will provide 1000MW of electricity, enough capacity to power up to 2 million homes. Energy Efficiency Homes across Great Britain will get extra support to make their homes cheaper and easier to keep warm thanks to reforms that came into force in April 2017. Changes to the Energy Company Obligation (ECO) will make sure energy companies give support to people struggling to meet their heating bills, with plans announced to extend the scheme from April 2017 to September 2018. Smart Meters A Smart Meters bill was included in the Queen’s speech in June 2017 to allow the Government to continue to oversee the successful completion of the rollout of smart meters and protect consumers, leading to £5.7 billion of net benefits to Britain. 2016 Energy Policy The Energy Bill received Royal Assent in May 2016. In summary the Bill: Creates the framework to formally establish the Oil and Gas Authority (OGA) as an independent regulator, taking the form of a government company, so that it can act with greater flexibility and independence. It gives the OGA new powers including: access to external meetings; data acquisition and retention; dispute resolution; and sanctions. It also enables the transfer of the Secretary of State of the Department for Business, Energy and Industrial Strategy (BEIS) existing regulatory powers in respect of oil and gas to the OGA.

  • Structural Integrity of Offshore Wind Turbines
    TRANSPORTATION RESEARCH BOARD Structural Integrity of Offshore Wind Turbines SPECIAL Oversight of Design, Fabrication, and Installation REPORT 305 Special Report 305 Special Report The United States is poised to begin building its first offshore wind energy power projects. To facilitate the orderly development of offshore wind energy and support the stable economic development of this nascent industry, the United States needs Structural Integrity a set of clear requirements that can accommodate design development. In this study, sponsored by the U.S. Department of the Interior’s Bureau of Ocean Energy Management, Regulation, and Enforcement (BOEMRE), the committee recom- of Offshore mends that BOEMRE develop a set of performance requirements that establish goals and objectives with regard to structural integrity, environmental performance, and energy generation. Because the committee found that the risks to human life and the Structural Integrity of Offshore Wind Turbines Wind Turbines environment associated with offshore wind farms are substantially lower than for other industries such as offshore oil and gas, it suggests that an approach with significantly less regulatory oversight may be taken for offshore wind farms.
