Bill D’Albertanson– Emergency Planning Manager Key elements of UK Power Networks emergency response
Transmission Networks There are four high voltage transmission networks in the UK. National Grid own and operate the transmission network in England and Wales The transmission networks act like the motorway system and enabling the bulk transfer of high voltage electricity (direct from large power stations) around the country.
Distribution Networks The electricity distribution SPN networks are regional grids that branch from the 2.3 million end customers national grids to deliver power to industrial, 8,200 sq. km service area commercial and domestic 37,000 km u/ground network users. 12,900 km overhead network Transformer Capacity 24,000 The UK Distribution Network MVA Operators' (DNOs) regions are shown on the map right, 4,200 MW peak demand together with those of independent distribution network operators who are ENA members.

How we manage incidents Structure • Regions and areas Command and Control • Strategic, tactical and operational • Decision making at lowest possible level and communications to the highest appropriate level • Gold Liaison Officers • Senior managers with technical knowledge and operational experience Three Top Electricity Risks • H38 – Rota Disconnections • H41 – Total Shutdown • H45 – Regional Shutdown
Civil Contingencies Act • The Civil Contingencies Act, and accompanying non-legislative measures, delivers a single framework for civil protection in the UK. • Those in Category 1 are organisations at the core of the response to most emergencies - the emergency services, local authorities, NHS bodies • Those in Category 2 organisations are the Health and Safety Executive, transport and utility companies and are ‘co -operating bodies’ • Category 2 responders have a lesser set of duties - co-operating and sharing relevant information with other Category 1 and 2 responders.
Bill D’Albertanson– Emergency Planning Manager The community risk register and our key risks
Community Risk Register • The National Risk Register • This is the first step in providing advice on how people and businesses can better prepare for civil emergencies. • Community Risk Register • The Civil Contingencies Act 2004 requires emergency responders in England and Wales to co-operate in maintaining a public Community Risk Register • These are approved and published by LRFs, which include representatives from local emergency responders as well as public, private and voluntary organisations
