The objective of this work is to gain a better understanding of whether the current design specification is adequate to cope with the largest credible earthquake in the UK. The second objective is to understand any implications to the National Grid system and assets from a lower intensity, higher frequency seismic activity that might be induced by fracking activities. Production of a network model, based on the impact of earthquake Production of a network model, based on the impact of fracking

GB Transmission network design standards to date have been based on withstanding the forces experienced in the event of an electrical fault which are considered to be greater than the forces from credible natural seismic events likely to occur in the UK. However, with recent developments in energy sourcing, including fracking, National Grid proposes to verify that this approach to seismic resilience remains valid in the future. Research Using a widely accepted risk assessment process commonly used in other industry sectors (for example Oil & Gas, Wind generation owners, and the PetroChemical Processing businesses), National Grid with Mott Macdonald will consider a full risk based approach to seismic analysis, covering the following areas: Seismic Hazard Vulnerability Exposure Network IntegrityNote : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above
