    Building Offshore Wind in England CORE: Centres for Offshore Renewable Engineering

    Building Offshore Wind in England CORE: Centres for Offshore Renewable Engineering BUSINESS IS 2 Building Offshore Wind in England Ministerial Foreword Offshore wind is a UK success story and the UK is open for business. The UK is the world leader in offshore wind. We have more offshore wind installed than anywhere else in the world. We are an island nation, blessed with strong winds and shallow seas – and this energy resource is on our doorstep. We are determined to move to cleaner electricity generation and offshore wind has an important role to play in our long term plan for a balanced, low carbon energy mix. I want the UK to secure the economic benefits of this new industry. Through our offshore wind industrial strategy, the Government is committed to working in partnership with business to build a competitive, innovative UK supply chain for offshore wind, delivering jobs and economic growth. Building a strong supply chain needs the commitment and expertise of local partners, working alongside central government to support businesses who want to invest here. The Centres for Offshore Renewable Engineering (CORE) partnership offers an integrated and cooperative approach between Government and Local Enterprise Partnerships in England, to provide the best possible support to businesses choosing England as an investment location. The Rt Hon Matthew Hancock MP Minister of State for Business, Enterprise and Energy CORE brings together the relevant expertise from UK Central Government and the six major investment hubs in England to support business growth and showcase opportunities for foreign direct investment (FDI) for the offshore wind sector.

Under the Environmental Permitting (England & Wales) Regulations 2016 (schedule 5, part 1, paragraph 19) a variation may comprise a consolidated permit reflecting the variations and a notice specifying the variations included in that consolidated permit. Schedule 2 of the notice comprises a consolidated permit which reflects the variations being made. All the conditions of the permit have been varied and are subject to the right of appeal. Purpose of this variation: Article 21(3) of the Industrial Emissions Directive (IED) requires the Environment Agency to review conditions in permits that it has issued and to ensure that the permit delivers compliance with relevant standards, within four years of the publication of updated decisions on Best Available Techniques (BAT) Conclusions. We have reviewed the permit for this installation against the revised BAT Conclusions for the large combustion plant sector published on 17th August 2017. Only activities covered by this BAT Reference Document have been reviewed and assessed. This variation makes the below changes following the review under Article 21(3) of the IED and the consolidation of the Environmental Permitting Regulations that came into force on the 4 January 2017: Revised emission limits and monitoring requirements for emissions to air applicable from 17 August 2021 in table S3.1a; Inclusion of process monitoring for energy efficiency in table S3.4.

Home working and lockdown periods have meant a decrease in energy use from commercial and industrial consumers and contributed to a decrease in electricity demand. The lockdown coincided with the traditionally lower demand period, as warmer, longer days require less electricity for lighting and heating than in winter months. The growth in generation connected at distribution level also lowers the demand seen on the transmission system during windy and/or sunny days. At times, electricity demand in Great Britain has been 20% lower than we would otherwise expect, and on 28 June it dropped to its lowest ever level of 13.4GW (prior to 2020 the lowest national demand figure observed was 15.8 GW).
