Dealing with Large Scale Power Emergencies Applying The Lessons Learnt From Global Case Studies In The South African Context Shamal Sivasanker AMEU Conference 2007
The world as viewed from above Conservative Estimation of affected customers: 500 million people affected since turn of the century Demand growth: 18.5% growth in energy consumption since 2000 Source: EIA
What has been driving this growing trend on a global basis? Demand • Growing industrial and residential demand • China & India economic growth • Pressures on primary energy – fragility of supply lines Natural Phenomenon • Impacts of natural weather e.g. Hurricanes, Tsunamis, effects of changing weather conditions Human induced outages • Skilled labour is a shortage in the Global Industry – leading to constraints in operating Ageing Networks • Ailing infrastructure across the globe • Lack of investment in terms of refurbishment and replacement – particularly in T & D infrastructure Managing these issues develops more complexity
Eastern US - August 2003 Situation Root Causes • Hot Summer • Equipment out for repairs • System close to limit • Lack of dynamic reserves • Poor forecasting • Lack of awareness • Poor vegetation management • Poor real-time support Recommendations Lessons Learnt • Strengthen compliance through audits • Evaluate vegetation management • Clarify stakeholder role • Improve staff training • Enhance system tools • Non-compliance Fragility of system • Poor operation and communication processes • Lack of stakeholder involvement
London 2003 Situation Root Causes • Reuse of equipment • Installation of wrong equipment • Faults and oil leaks caused maintenance rescheduling • Planned outages • Misinterpretation of alarm • Switching out of SGT3 left power supply to single circuit • Circuit breakers at single circuit tripped Recommendations Lessons Learnt • Human error from relays increasing worldwide • NGC & contractors made errors in scheme delivery • NGC practices not rigidly enforced • Increased stakeholder involvement • Investigation of equipment installation • NGC review ops procedures • Ofgem penalty for incidents
Italy 2003 Situation Root Causes • 15 highly heavily loaded lines on Italy North border • Italy’s 6400MW import increased by 200 – 300 MW • Swiss grid also under pressure • Poor vegetation management • Inability to re-close line • Lack of urgency • Angle instability and voltage collapse Recommendations Lessons Learnt • System was close to limits • Blackout triggered in Switzerland • Human, technical and org factors prevented quick system restoration • Inter-TSO cooperation • UCTE Operation handbook and DACF review • Evaluation of tree trimming • NGC to enforce min reqs. • Investment in transmission
So what where the common issues? Infrastructure and Investment • Re-use of old equipment (resulting in fragile systems) • Neglect of current equipment (resulting in fragile systems) • Poor vegetation management • Lack of real-time reporting equipment Stakeholder Involvement • Non-compliance with guidelines, regulations and standards • Lack of agreed upon standards in some cases • No collaboration between parties in pursuit of common purpose • Poor role definition of stakeholders Human Error • Insufficient training (resulting in mistakes in operating equipment and misinterpretations of situations) • Lack of skilled and experienced operators Weather Affect • Seasonal affect on demand of energy (causing record peaks) • Causes damage and deteriorates equipment Operations and Processes Laid out by Relevant Bodies • Grids were operated at levels close to critical levels in every case • Operational procedures in emergency situations inadequate
So how did the Electricity Industry respond, and what were the lessons learnt? Preparedness Risk Risk Management
The SA Context Building Agility in Utilities to ensure effective response Practices Business Continuity Management • Closer integration and collaboration in the industry • Processes that extend across boundaries • Governance that is clearly defined in the case of emergencies • Pre-defined protocols • Building in organisation flexibility and adaptive capacity Streamlined Emergency Management Processes Clearly Defined Governance

The SA Context Preparing for Strategic and Operational Response Practices Scenario Planning • Identification of strategic risks • Integrated forums with key stakeholder groups to establish business continuity plans • Integration with National Disaster Recovery • Establishment of a command centre(s) • Running preparedness simulation exercises to create awareness and help check level of readiness. Standardised Emergency Response Plans Preparedness Exercises & Indicators
The SA Context Strategic Management of Stakeholders Practices Be Visible • Different stakeholders need different approaches • Deal with the facts • Ongoing interaction with stakeholders on the Electricity issues • Address your stakeholder concerns • Win them over! Don't Hide The Bad News Communicate Frequently Address Perception Vs. Reality Be Empathetic

“Want of foresight, unwillingness to act when action would be simple and effective, lack of clear thinking, confusion of counsel until the emergency comes, until self-preservation strikes its jarring gong – these are the features which constitute the endless repetition of history.” Sir Winston Churchill Phezu Komkhono
