The order of the day • 4 booths, each dedicated to a different theme • Booth 1: Managing and storing our materials • Booth 2: Black Start and network resilience • Booth 3: Intelligent network control • Booth 4: Our asset replacement programme • Each of you has a coloured sticker on your name badge • When you hear this sound, you move from your tables to a booth – to hear about our investment options • When you hear this sound, you move from the booth to your table – to give your feedback on these options

Engagement exercises • For each of the four topic areas we would like to hear your thoughts on which of the investment options presented is most appropriate for our T2 Business Plan • The options are split into the following: • … but each has a different cost implication • At the end of the day, we will revisit your choices in light of these cost implications

What is Resilience? Reliability Redundancy Resilience Resistance Response & Recovery

The cost for better reliability and resilience? 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 Long term Pre Cost System Status Disaster Restoration disaster Recovery Resilient Network Tipping Point Less Resilient Network Reliability t0 t1 t2 t3 t4

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

External threats • Wannacry Cyberattack May 2017 • 200,000 computers over 150 countries • 1% of NHS activity impacted • Cost to the NHS of £92m Sources: BBC and The Telegraph

Examples of Asset Issues https://vimeo.com/300997438

Mini-Blackout 2014 • Over ¼ of connected customers lost power • Lasted up to 6 hours in some places • The Unsupplied Energy was 133.9 MWhrs • Annual Energy Not Supplied incentive breakeven is 120MWHrs • Lost £1.7M in incentive payments for the event • Small levels of compensation to generators • DNO penalty costs were around £300K Image Source: BBC

How do we secure our Network? Asset Replacement Communications Material Management Reliability Redundancy Resilience Protection Control Centre Resistance Response & Recovery Intelligent Monitoring Climate Change Cybersecurity

Delivering the Strategic Themes Safe and Secure Sector-leading Stakeholder-led Leadership in Network Operation Efficiency Strategy Sustainability Taking a whole system Use data efficiently to Integrated approach to Trusted partner of approach to network understand, predict and whole life development customers and operation and get the best network communities, realising and operation, using risk- development to meet performance based engineering to long term benefit for current and future deliver value society, economy and customers’ needs environment

Stakeholder Led Strategy • We need to ensure that our future plans meet the Stakeholder-led requirements of our stakeholders Strategy • Your views are vital to our plans • We will be discussing some of our proposals with you and asking for your opinions • Climate Change is being discussed at a separate event Taking a whole system approach to network operation and development to meet current and future customers’ needs
