  2. 1 of 10 Batho Pele – putting People first • Redress the imbalances of the past • Maintain continuity of services to all • Focus on needs of 40% living in poverty • Shift away from bureaucratic systems • Search for ways to put the public first • Better, faster and more responsive to needs The Service Delivery Challenge includes welfare, equity and efficiency

  3. 2 of 10 Escalating Service Expectations • 1940’s – Showing Store owner exhibits goods at shop • 1950’s – Telling Travelling salesmen describe features • 1960’s – Selling Marketing emphasis benefits of service • 1970’s – ChoiceCustomerselects from diverse options • 1980’s – NowCustomerselects quickest respondent • 1990’s – “I”Customerimposes personal preferences • 2000’s – ValueCustomerpurchases best value (cost?) • 2010’s – SavingCustomerreduces use by conservation • 2020’s – ControlCustomerexpects service integration • 2030’s – MorphCo-generation and adaptive infrastructure New assets provide services for 3 decades

  4. 3 of 10 Service Convergence ignites Innovation • Prepayment – IEC 62055-xx (TC13 WG15) • CRP evolves into VTC port • Auto Meter Reading – IEC 62056-xx (TC13 WG14) • FLAG evolves into DLMS technologies • Demand Side Mng – IEC 62054-xx (TC13 WG11) • Ripple control evolves into ??? • Auto Meter Mng – IEC 61968-x (TC57 WG14) • MDL evolves into CIM System Integration and Security are key

  5. 4 of 10 Multi-service Meters for Consumer Choice • Conventional online billing • Prepayment online vending • Indigent offline social grants • Repayment arrear collections • Time based tariff deemed profiles • Real time priced post processed • Demand limitedutility vs consumer imposed Adaptable for on grid, renewable & off grid

  6. 5 of 10 Multi-function Meters for Quality of Service • Main isolator Installation safety • Over current Installation safety • Fault current Installation safety • Earth leakage Consumer safety • Lost neutral Consumer safety • Raised neutral Consumer safety • Over temperature Consumer safety • Over voltageAppliance protection • Under voltageAppliance protection • Lightning surgeAppliance protection Disadvantaged need Appliance Protection

  7. 6 of 10 Improved Revenue Assurance capabilities • Tamper switch fails when supply down • Imbalance detect good for BS meters • Bypass detector can’t tell if load switch fused • Zero current det. can’t tell if switch jammed • DC current det. can’t tell if non linear load Capacity Restriction instead of disconnect Site Audits instead of AMR & tamper detect

  8. 7 of 10 Summary of Smart Meter capabilities • People centric, user friendly product • Multi-service capability for consumer choice • Multi-function capabilities for quality of service • Advanced revenue assurance features • Energy efficiency expansion options • Data simplicity, integrity and accessability • Logistic simplicity and lower operating cost Seamless integration & global Economics

  9. 8 of 10 Active Standardisation Activities • SANS 1524-1 Ed5 local SA requirements • SANS 1524-3 np mounting and enclosures • IEC 62055-52 cd improved serial interface • IEC 62059-31 cdv dependability testing • IEC 61968-9 cdv data elements & modelling • STS wg3 tou tariffs and water req’s • STS wg4 governance and IP policies • STS wg6 universal meter numbering • STS wg7 compliance testing method

  10. 9 of 10 Pending Standardisation Activities • SANS np outdoor & poletop meter req’s • STS wg5 np global key mng infrastructure • STS np supply group code restoration • STS np field support short codes • STS np service mode selection method • NRS 086 np consumer activated DSM • NRS np improved meter sealing methods Appoint & Mentor standardisation experts

  11. NRS, SANS and SANC Conclusions • Service expectations are continually increasing • Smart meters must provide services of+for next 3 decades • Seamless integration and standardization are essential • Universal systems instead of ad-hoc pilots (IEC, ISO, ITU) • Fragmented islands encourage exploitation Investment in standardization experts will be far less than the challenge of patching together diverse legacies
