What is Resilience?

Reliability Redundancy Resistance Response & Recovery Resilience

slide-13
SLIDE 13

What is an acceptable investment level? ➢ Acceptance that no system can be made 100% reliable ➢ When does the costs outweigh the benefits? ➢ Cost Benefit Analysis to guarantee that the tipping point is never reached ➢ Beyond this tipping point the costs will rise exponentially for little benefit

Threats to our Network

Threats to the reliability of the Electrical network ➢ Technology; Change to standards, malicious intent, technical failure, changes to global supply chain’s focus ➢ Geopolitical; Political instability, societal expectations, physical and cyber attacks ➢ Natural Hazards; Geological hazards including fault lines and land slips, extreme weather including flooding and drought, solar storms, moorland fires, difficult to reach plant and equipment ➢ Electrical Network; Resource availability, capability, and knowledge, single points of failure, reliance on critical circuits, blackstart, ageing assets
