    Hinkley Point News from EDF Energy July 2009 Site Nomination Update EDF Energy recently nominated to Government an area of land adjacent to the existing Hinkley Point nuclear power stations for the development of new nuclear power. The aerial plan shows the full extent of the land that has been nominated. Not all of this land will be required for the development of new nuclear power, and not all of it will necessarily be needed during the construction process. Nominated Land Area Detailed feasibility and design work is currently underway to determine the precise location of the power station and associated buildings. This work will also determine the exact boundaries of the land needed for the construction period. Land used temporarily during the construction process will be restored afterwards. EDF Energy has also nominated sites for Area of land nominated by EDF Energy for new nuclear build new nuclear build in Dungeness (Kent), Hartlepool (Teesside), Heysham Further details of our nomination of development can be obtained from (Lancashire) and Sizewell (Suffolk). land for new nuclear power www.nuclearpowersiting.decc.gov.uk .

  • Position Regarding Future of Hartlepool Power Station November 2017
    Position regarding future of Hartlepool Power Station November 2017 This position statement has been prepared based on information available on EDF Energy’s website, NuLeAF (Nuclear Legacy Advisory Forum) website and information provided from officers within Hartlepool Borough Council. Background The nuclear power station in Hartlepool is managed by EDF Energy; it is capable of supplying energy to over 2 million homes in the UK. The power station started energy generation in 1983 and the estimated end of generation date is 2024. The current site employs approximately 530 people full time and a further 200 full time contract partners. Many of the nuclear power stations currently in operation across the UK are coming to the end of their operational lifespan and nuclear investment plan is underway. Whilst the current end of generation dates of these sites are not set in stone, there is probably little scope for any significant further extension of the operating lifetime of the power stations. EDF Energy is currently developing three new nuclear power stations (Hinkley Point C, Sizewell C and Bradwell B). More will be required in the future to replace aging power stations. Decommissioning In relation to decommissioning of the site, EDF gave the following overview of the three key phases at a recent NuLeAF meeting has drawn up decommissioning plans which divide into three phases: 1. Pre-closure transition and defueling (the defueling period is likely to take 3-4 years). 2. Site surveillance and Care & Maintenance 3. Reactor decommissioning and final site clearance. From start to finish this covers a period of approximately 100 years.

  • Torness Monthly Report August 2017
    Torness monthly report August 2017 Introduction We are keen to hear the views of our local communities. We recognise that good communication is a two way process and we welcome your feedback and comments. While we will do our best to always use plain English, talking about our business sometimes involves specific terminology, and you will find a glossary of any terms used at the end of each monthly report. Safety • The station had zero lost time incidents (LTI) during the reporting period. EDF Energy staff have had 448 LTI free days (more than a year) up to 31 August and contract partners have had 1148 LTI free days up to 31 August – that’s more than three years. • The station had no emergency services call outs during August. • There were two first aid injuries at the station in August. • The station had no environmental events during August and has gone 2390 days without an environmental event (over six years). Station output Two flasks containing spent fuel were safely transported to Sellafield for reprocessing during the period. Both reactors were operational for the whole month. Station news Torness teams up with Police Scotland to improve road safety Torness power station and Police Scotland have been working hard to teach apprentices about the dangers of taking risks whilst driving. The station recently joined forces with Police Scotland to improve road safety by carrying out a number of road safety presentations. The Young Driver Early Intervention was aimed at educating younger drivers (17-25) on the consequences of excess speed and hazards associated with inexperience and bravado.

    Detailed responses to the CMA Invitation to Comment Theme one: developing competition while incentivising investment 1. How is the EV charging sector developing and how will technological or other developments (for example smart technologies) impact sector development and competition? The EV charging sector is expanding rapidly, responding to both current and anticipated growth in electric vehicle sales. Department for Transport data indicates that, as of 1 April 2020, there were 17,947 public electric vehicle charging devices available in the UK. Of these, 3,107 were rapid devices. Since 2015, the number of public charging devices has grown by 402%, with a 61% increase from 2018 to 2019. Rapid charging devices have also grown quickly, increasing by 355% since 20151. Recent years have seen a significant expansion in the number and variety of companies seeking a presence in the EV charging sector. These now include: • Dedicated chargepoint infrastructure providers (e.g. Pod Point, Chargepoint, EV Box, Instavolt, Ubitricity) • Entrants from the utility sector, building on their links with the electricity system and seeking to take advantage of their expertise in electricity generation, supply, pricing and associated services (e.g. EDF, Centrica, Ovo, EON, Engie) • Entrants from the oil and gas sector, seeking to take advantage of their existing forecourt presence to provide new options for public EV charging (e.g. BP, Shell, Total) • Automotive companies (e.g. Tesla, BMW, Volkswagen) offering their own bespoke charging solutions • Companies focussed on e-mobility service provision and building roaming platforms/services between different EV charging infrastructure (e.g. Virta, Zap-Map) • New entrants focussed on building a presence in specific aspects of the EV charging market (e.g.

The implementation of a tidal scheme in the Severn estuary, especially a large one (or a combination of smaller schemes), would require not only a great amount of materials and equipment but also large scale innovative construction design and installation processes (numerous caissons, long embankments, sluices, locks etc).
