4. Overview and Key Activities The safety of staff, Contractors and 3rd parties including the public. Direct interaction with Customers providing real-time information on the status of network faults and complaint management through our Customer Service Centre. Rapid restoration of customer supplies through the Dispatch of First Response Technicians, Engineers, Jointers and Linesmen. Safe, efficient and effective day-to-day management and control of EDF Energy�s distribution network via our Operation Centre. Delivering the programmes of work associated with repairing network faults, new connections, infrastructure reinforcements and maintenance of our assets. Emergency, Business Continuity & Disaster Recovery Planning Network records and plan provision to third parties

5. Responding to Network Emergencies All continuity plans regularly reviewed, tested and revised:  Network Emergencies  Black Start Rota Disconnection Demand Management System Emergencies � weather related incidents Disaster Recovery  Business Continuity Generator & NGT Transmission failures

6. Business Continuity EDF Energy needs to ensure compliance with all of its legal and regulatory obligations (including Licence Conditions). Business Continuity Planning is undertaken on a risk based approach following best practice as defined by the standard BS25999 Business Continuity Management is a holistic management process that identifies potential threats to EDF Energy�s businesses and the impacts on business operations these might cause, and which builds a framework for resilience. It ensures a planned response to major disruptive incidents, which is aimed at minimising the impact and maximising the recovery and resumption to normal business. All business areas and corporate functions are required to maintain Business Continuity Plans and appropriate documentation for their area of control. This is managed by appointed BC Coordinators

7. Business Continuity continued EDF Energy�s objectives of developing a BC capability are to: � Establish best practice BC processes and procedures within EDF Energy. � Ensure robust, current and consistent BC Plans are developed appropriate to the level of risk. � Ensure Risk Assessments and Business Impact Analyses are carried out annually and at any significant change in function, people or location. � Establish a reporting framework and monitoring process to ensure all EDF Energy branches have Emergency Management, Incident Management, Business Continuity and Disaster Recovery plans in place. � Specify and manage an exercise programme to ensure plans are regularly tested. � Develop and manage assurance procedures to ensure all plans are adequately maintained. � Ensuring also that any residual risks appear on the appropriate Company or Branch Risk Register.

8. Example BC Plan for a critical site Assessment of the risks, (probability, potential impact, mitigating action required to reduce impact in a controlled manner) Nature of Risk Potential impact on compliance with achievement of business targets Potential Risk of breach of legislation Immediacy of risk Expected duration of risk Concurrency with other business risks. Areas considered Loss of staff � e.g. Flu Pandemic Loss of buildings � e.g. flooding, access problems or total loss Loss of power supply short term � 3-4 hours Loss of power supply long term � 24+ hours Black start � National failure of the transmission system Loss of systems � IT and Telecom infrastructure. Loss of water, sewage and gas utilities � Health and safety Loss of communications � voice data (mobile, fixed lines)

9. Example BC Plan for a critical site in Ipswich Security of the electricity supply by duplication of supply at all voltage levels with automated change over schemes in the event of failure. The provision of Uninterrupted Power Supply (UPS) to maintain supply to critical IT/Telecom systems in the event of voltage disturbance. The provision of fixed generation with auto change over facilities with enough fuel to hold full load for 72 hours. The provision of mobile generator connection points to the plant switch room. Resilience and duplication of internal electrical circuits, data and telephony lines/switches (no one point of failure). Duplicate IT servers across different sites which are in full replication Provision of an alternative site in the event of loss of building. Identification of critical functions and timescale required for restoration. Loss of people plan - Flu Pandemic

10. Information and recommendations EDF Energy does not have the obligation to provide Business Continuity for loss of electricity to customers. Under day to day conditions we do use mobile generators to restore supply to small groups of customers but we are not obliged to do this. If the customer numbers are too large or the number of incidents to great (severe weather) we do not normally provide generators. EDF Energy can not guarantee a 24-hour supply EDF Energy Networks are regulated and have Guaranteed Standards of performance. Small payments are made to customers if we fail to restore the supply within 18 hours (�50 -�100), however this extends to longer periods in certain circumstances such as major events or severe weather. EDF Energy are obliged at all times to comply with the Licence Conditions set by the regulator therefore our BC plans are designed to ensure we comply at all times. EDF Energy have a mutual aid agreement with all other Distribution Network Operators in the UK EDF Energy also have a mutual aid agreement with EDF France.

11. Considerations. Consider what you would do without power for 3-4 hours or 18-24 hours. Not just for major events as EDF Energy do sustain faults and damages on the network every day. How secure is you supply? Do you have an alternative supply (UPS and generation), if so when were these last load tested and how much fuel do you hold? Will your plant farm allow connection of a mobile generator easily? If you do not have a fixed generator do you have a contract with a plant hire company? Do you know what to do in the event of a power supply failure and who to contact?
