11 PART II GENERAL ISSUES ON METERING PROJECTS

12 Mission critical METERING PROJECTS Thin line between project and production, especially for retrofit projects Unit cost low but cumulatively the value can be high

13 ZETDC MIGRATING TO SMART/PREPAYMENT METERING New Drivers, New Forces!

14 THREE KEY PROJECT DELIVERABLES TO SPECIFICATION WITHIN BUDGET DELIVERED ON TIME PERFORMANCE AND FUNCTONALITY AVOID COST OVERRUNS & SCOPE CREEPAGE ADDRESS ISUES AS THEY ARISE & CONSTANTLY MONITOR PROGRESS

15 Comprehensive Framework to guide the Metering Project Implementation

16 COHERENT TACTICAL PLANS FOR METERING PROJECTS

17 STAKEHOLDER ENGAGEMENT/INTERACTION CUSTOMER EDUCATION PRODUCT ENGAGEMENT 1 PROMOTION 2 METER OEM UTILITY CUSTOMERS 3 4 UTILITY SPECIFICATION (CUSTOMISATION) FEEDBACK/ CONFRONTIONAL REACTION

18 KEY DRIVERS FOR THE METERING PROJECT 1 Key driver Reduction in Revenue Leakage (NTL) 2 Energy efficiency 3 Address collection Challenge which had gone down to around 60% Critical Success Factor (CSF) Drop in cases of meter tampering to desired levels. Meters being installed have tamper evident features and the system runs exception reports to help identify Realisation of energy efficiency objectives Collection index to improve to more than 100%

19 TARGETTED & TAILORED APPROACH METERING TECHNOLOGY CUSTOMER CATEGORY KEY DRIVERS STS Prepayment Metering Technology Smart Metering Technology The Meters must support pre-payment operation with the credit purse in a higher-order system such as MDMS Residential and Small Business Customers with Capacity of 100A and below (650,000) Medium & Large Power Users (CT & CT/VT Connected Meters). (40,000) Address MBC Issues Enhance revenue protection Encourage Efficient utilisation of electricity Address MBC Issues Key milestone towards establishment of Smart Grid Societal benefits

35 CONCEPTUAL MODEL FOR PILOT PHASE

36 REQUIRED SMART METER FUNCTIONALITY Specified Smart Metering functionality should be guided by business requirements envisaged operational and societal benefits Due Diligence should be carried out to deal with technological uncertainties and ensure value will be derived from the investment Consider operability issues to avoid lock in Multiple communication Channel

37 SMART GRID OBJECTIVES Item Description Expected Improvement 1 Sustainable reduction in Zimbabwe s peak energy demand relative to the 2014 national baseline 20% 2 Grid availability to serve all critical loads as defined nationally 100% 3 Improvement in system efficiency (measured against the national and local technical and non technical losses baseline) 40% and asset utilization to achieve a load factor of 70%. 4 80MW electricity capacity integrated into the Distribution networks from renewable energy sources 800MW 5 Improved service delivery and service reliability to customers to a achieve a customer satisfaction index that exceeds 80%. Above 80%

50 PURPOSE OF PRESENTATION

51 LESSONS LEARNT FROM ZETDC PROJECTS Metering project should be consistent with Utility s broad Corporate strategy Carry out Due Diligence to address technical uncertainties & Be clear of benefits upfront Follow best practice Project Management Methodologies (PRINCE 2, PMBOK) Carry out risk Analysis and come up with mitigation plan Verify formal competencies and ensure the right skill level Define and control processes and subprocesses at a programme and project level Consult all stakeholders before making key decisions Installation of protective structures must be done in parallel with meter installations Closely manage integration points at various levels and across value chain to avoid gaps
