3backgroundELECTRICITY IS A KEY DRIVER OF ECONOMIC GROWTH & MAJOR INPUT IN ALL ECONOMIC SECTORS - AGRICULTURE, MINING, MANUFACTURING AND TOURISMZESCO’S ELECTRICITY GENERATING CAPACITY STANDS AT 2.2 GW (99% HYDRO)NET EXPORTS ROUGHLY 5% OF TOTAL GENERATION (MOSTLY TO NAMIBIA, BOTSWANA AND CONGO D.R.)CURRENT PEAK DEMAND FOR ELECTRICITY BARELY MEETS GENERATION CAPACITY ESPECIALLY DURING PEAK TIMES
4background CONT’DZAMBIA HAS EXPERIENCED A SUSTAINABLE ECONOMIC GROWTH OVER THE LAST FIVE YEARS DESPITE GLOBAL RECESSION, RESULTING IN:INCREASED DEMAND FOR ELECTRICITY FROM ALL SECTORSDEMAND OUTSTRIPPING AVAILABLE CAPACITY DURING PEAK HOURSZESCO MUST INVEST IN NEW INFRASTRUCTURE TO COPE WITH GROWING DEMAND
5BACKGROUND CONT’DHOWEVER DELAYED INVESTMENT IN GENERATION PLANTS HAS NOT MATCHED THE LOAD GROWTHRESULTING IN DEFICIT IN POWER GENERATION CAPACITYFURTHER, DELAYED INVESTMENTS IN TRANSMISSION & DISTRIBUTION SYSTEMS HAS ALSO LED TO DEPLETING POWER TRANSMISSION & DISTRIBUTION CAPACITYABOVE FACTORS LARGELY CONTRIBUTE TO LOAD-SHEDDINGLOAD-SHEDDING IS DONE TO SAFEGUARD THE ELECTRICITY INFRASTRUCTURE

11SHORT TERM MEASURES TAKEN TO REDUCE LOAD-SHEDDING GENERATIONrehabilitation and uprating of the three major hydropower stations, i.e. Kafue Gorge, KNBPS and Victoria FallsVICTORIA FALLS POWER STATION – USD53.7MILLIONKAFUE GORGE POWER STATION - USD 85.5 MILLIONKARIBA NORTH BANK POWER STATION – USD81.4MILLIONThrough the uprating of kariba and kafue gorge 210mw was gainedTOTAL COST OF the UPGRADE– USD 100 MILLIONESTIMATED COST FOR A 210MW new hydro POWER STATION– above us$600MILLION
12GENERATION PROJECTS POWER REHABILITATION PROJECT (PRP) Scope included rehabilitation and uprating of the three major hydropower stations, i.e. Kafue Gorge, KNBPS and Victoria FallsOther works included reinforcement and rehabilitation of some transmission and distribution infrastructureThe major achievements of the PRP has been the uprating of the Kafue Gorge Power Station from 900 to 990 MW, the reinstating of the Victoria Falls Power Station to its full generating capacity of 108 MW as well as the up-rating of Kariba North Bank power station from 600 MW to 720 MW. The total generation capacity yielded from the PRP is 210 MW

51POWER PURCHASE AGREEMENTS WITH independent power producers to ensure load shedding is minimized zesco has contracted power from Ipps at higher cost compared to the prevailing tariffs on the market.Avearge tariff UsC/KwH -6.02Annual loss of 367 million USD
52REASONS FOR LIMITED INVESTMENTS IN THE ELECTRICITY SECTOR THE ELECTRICITY ENERGY SECTOR IN ZAMBIA HAS SUFFEREED LITTLE OR NO INVESTMENT DESPITE GOVERNMENTS INITIATIVE TO HAVE THE INDUSTRY DEREGULATED DUE TO LARGELY:NON COST REFLECTIVE TARIFFLACK OF WILLINGNESS FROM CUSTOMERS TO PAY COST REFLECTIVE TARIFFSZAMBIA HAS THE LOWEST TARIFFS IN THE REGION.
53POWER PURCHASE AGREEMENTS WITH independent power producers DUE TO THE UNATTRACTIVE TARIFFS, the ZAMBIAN ELECTRICITY SECTOR IS LARGELY DOMINATED BY ZESCO –SINGLE BUYER MODEL.
54SOLAR ENERGY OPTIONSolar energy can only be harnessed when it is daytime and sunny.Less efficient and costly equipment (Efficiency for most panels between 17-20%)Reliability Depends On Location, climate, pollution e.t.cEnvironmental Impact of PV Cell ProductionRequires large tracts of land for solar panels and batteriesNo feed-in tariff in place –must be developed by Memwd and ERB
55SOLAR ENERGY OPTION Cost of solar energy very high Example to PROCURE AND install a 25kwp it costed ZESCO ABOUTusd 300,000
56Other initiatives to reduce load-shedding Power plants will take time to come on boardTherefore ZESCO Management stepped up DSM activities to accelerate energy efficiency initiativesEnergy saver lamp (CFLs) distributionPower Alert SystemEnergy Audit and Power Factor CorrectionSolar Power TechnologyTime of Use Tariff (TOU)Ripple control of electric geysersPrepayment metering
57Demand Side Management (DSM) DSM is a utility program aiming to fine tune consumers energy consumption pattern according to utilities energy production and distribution capacityTo reduce load-sheddingTo release system capacityMake available additional power for new connectionsReduced energy bills for customersPromote energy efficiency and save the environment

61POWER ALERT SYSTEMThe Power Alert System is essentially a communication tool that utilizes the television and radio media as the channel to inform electricity consumers on the energy situation in the Power network thereby prompting Customer response.The system therefore triggers voluntary participation of consumers in electricity demand reduction by switching off unnecessary loads in response to the broadcast power alert message.
63SOLAR POWER305 out of 1,000 Solar Geysers installed mostly in Government Institutions and transit Homes (with 566KW power savings).Remaining solar geysers to be installed in ZESCO Institutional Houses mostly at power stations & Service CampsZESCO HQ office lighting and Parliament Emergency supply already on Solar PowerAt ZESCO HQ 1,850 LEDs retrofitted in fluorescent fittings
64RIPPLE CONTROL SYSTEM Means of load shaving (instead of load shedding) Mainly targeted at electric geyser loadsInitially targeted at 100,000 Residential Customers in LusakaProjected load of about 135MW to be savedCan be implemented even under system emergenciesTechnical specifications drawn. Financing arrangements underway
66conclusionZesco limited has embarked on various projects from the production side through to distribution to reduce and ultimately stop load-shedding.Government being the major shareholder has given support through provision of equity and guarantees for debts being contracted to finance the projects.Load-shedding in Zambia, the plan is therefore to ensure cost reflective tariffs in order to attract invest in the generation, transmission and distribution electricity infrastructure.
