3 QUICK FACTS ABOUT JOHANNESBURG

4 JOHANNESBURG AT A GLANCE City Power s Area of Operation CITY OF JOHANNESBURG

5 JOHANNESBURG AT A GLANCE Early days of the true African city Founded in 1886 with a discovery of gold; Migrants from all four corners of the planet; Busiest mining spot in the world; The need to control the City and its gold was at the centre of the second Anglo-Boer war;

6 JOHANNESBURG AT A GLANCE Modern Johannesburg World s largest dry port city; Home to 40% of the planet s human ancestor fossils; Source of 40% of all gold ever produced; World s biggest man-made forest city (10 million trees); Metropolis cover an area larger than Sydney, London or New York;

37%; About 40% of the population is under 25; Over 90% of the citizens have access to

7 JOHANNESBURG AT A GLANCE Johannesburg by numbers* Over 4.4m people call Johannesburg home; From 2001 to 2011, the city s population increased by 37%; About 40% of the population is under 25; Over 90% of the citizens have access to electricity and clean water; Contributes 16% to South Africa s GDP Accounts for 40% of Gauteng s economic activity *Stats SA, Census 2011

8 QUICK FACTS ABOUT CITY POWER

9 CITY POWER S VISION A World Class Electricity Distributor

10 CITY POWER S BUSINESS MODEL National Energy Regulator of South Africa (NERSA) IPP: Kelvin Generation Transmission Distribution We are in the business of buying electricity and selling it to customers.

5b invested in infrastructure over the past 10 years with R40b required in the next 20 years Over 60% of customers are on Prepaid;

11 CITY POWER AT A GLANCE 6 major intake points from Eskom; Current capacity demand of 3 500MW Predicted future demand to reach 6 000MW in 2030; More than customers; Approximately R8.5b invested in infrastructure over the past 10 years with R40b required in the next 20 years Over 60% of customers are on Prepaid; 60% of the all system faults are directly attributed to cable / copper theft in November 2013; A total of over 1600 employees; Only utility in Africa that has three ISO accreditations (9000, and 18001);

12 CHALLENGES OF A TYPICAL AFRICAN CITY Status Quo

13 CHALLENGES FACING AFRICAN CITIES Rapid Urbanisation Population in urban areas in 1990 Population in urban areas in 2010 Close to 50% of Africans live in urban areas

14 CHALLENGES FACING AFRICAN CITIES Difficulty of providing infrastructure Slums and shanty towns; No access to water and electricity Over population swallows existing infrastructure; Lack of finance to improve the infrastructure; Strain health facilities and major environmental problems;

CHALLENGES FACING AFRICAN CITIES Theft of electricity In some African countries, non technical losses are over 30%; On average, 40% of City Power s system disturbances are due to cable theft;

15 CHALLENGES FACING AFRICAN CITIES Theft of electricity In some African countries, non technical losses are over 30%; On average, 40% of City Power s system disturbances are due to cable theft; Power outages result in job losses and electricity price increases; Cable theft may also result in loss of human life; In Nov and Dec 2013, up to 60% of City Power s outages were due to cable theft.

CHALLENGES FACING AFRICAN CITIES Limited financial resources Competing needs for the limited available financial resources; Most capital investments

16 CHALLENGES FACING AFRICAN CITIES Limited financial resources Competing needs for the limited available financial resources; Most capital investments require a secure supply of electricity catch 22 scenario; Highly unreliable electricity supply; Poor quality of supply of electricity in most African countries;

17 SMART GRID APPLICATIONS TO ADDRESS CHALLENGES OF AN AFRICAN CITY

18 SMART GRID APPROACH FOR AN AFRICAN CITY Smart Grid in Africa Revenue Protection Semi / fully privatised electricity industry Effective power regulation Demand Side Management

19 THE DIMENSIONS OF A SMART CITY

20 CITY POWER S SMART GRID APPROACH

21 CITY POWER S SMART GRID APPROACH Smart Grid is a Journey, NOT a Destination» Rollout of high speed broadband network to support Smart Grid» Full deployment of RTU down to the mini substation level» Network automation down to the distribution (feeder) rings» Application of Advanced Integrated Security Technology (AIST)» Move towards optimized maintenance regime through a risk based combination of time-based and condition-based maintenance

22 PROJECT 1: HIGH SPEED TELECOMS NETWORK Foundation of any Smart Grid Implementation Tier approach to full network development Tier 1 (Major Stations) Tier 2 (Other S/S & Sw/S) Tier 3 (DX & last mile) Backbone ring Sub rings topology Radio (licenced RF) Telecoms Platforms Fibre and Microwave Super fast Fibre and Radio network High Bandwidth and speed Moderate speed Limited bandwidth Redundancy Redundancy Bi-directional Layer 2/3 Ethernet Layer 2/3 Ethernet Moderate Latency capable capable Low Latency Low Latency

23 PROJECT 1 CONT. Telecommunication Rollout PROJECT DETAILS Project Name: Fibre Rollout Project Value: + R 200m Duration is Scope: Partial Implementation of Tier 1 & 2 Capacity: 48 SM Cores Philosophy: Fibre down to satellite S/S Potential speed of up to 10 Gb/s

24 PROJECT 1 CONT.. Implementation Approach Phase 1: Installation of fibre optic cables interconnecting all major intake stations (Reuven, Disaster Recovery Site (DRS) and depots) Tier 1 Core Network; 12 months from design to a full commissioned network; Phase 2: Deployment of microwave communication to complete entire supply area coverage; Project timelines are dependant on successful ICASA licence application process; Phase 3:Determine radio sites to install WiMax Mesh network. Apply for a user licence from ICASA. Timelines are ICASA approval process dependent.

25 PROJECT 2: NETWORK AUTOMATION Self Healing A Typical Future Substation Layout and associated protocols

26 PROJECT 2: NETWORK AUTOMATION Guiding Principles» All new substation designs are IEC compliant» Merging units are being tested for future deployment» Earth fault path indicators are being marshaled back to Control» Best wireless radio network is being investigated for last-mile purposes» Immediate plan is to retrofit motorised breakers to some of our load centres to test DX automation

27 PROJECT 3: THE METERING PROJECT The Technical Solution Customers < 1000kWh/month: Split Pre-paid solution Convert customers to split prepaid meters with bi-directional communication Installation of independent load management controllers. Installation of protective structures Install remote meter monitoring systems Customers > 1000kWh/month: Smart Meters Convert to smart meters (with load management, ToU functionality and ability to be on pre-payment or conventional metering with fraud detection capability) Bi-directional metering infrastructure Large Power Users: Smart Meters Convert to smart meters Perform technical audit on metering accuracy Time of Use tariff Power conservation scheme through pricing signal Technical Data Completeness Audit all stands in areas where supply is provided Locate all meters with GPS coordinates. Possible joint operation with other entities Communication campaigns 27 Technical/Non-technical Losses Installing stats meters at all of our substation incomers, feeder boards and switching stations Installing bulk metering for intake points as check meters Installation of capacitor banks Organizational Capability Establishment of Energy Management back office Establishment of revenue protection response team (to deal with bypass/faulty meters etc.) Introduction of energy champions to provide energy services to Large Power Users

33 CONCLUSION

34 CONCLUSION» Smart City / Grid concept in a journey rather than some end state» Key drive should be to have a happy customer at the end» Development of clear business case is critical» City Power is poised to take full advantage of possibilities presented by the Smart Grid concept
