Accesstoelectricityinsub-SaharanAfricaisaroundthe32%mark,withover620millionpeoplehavingnoelectricityconnection(InternationalEnergyAgency,2014).Thecloserelationshipbetweendevelopmentandaccesstomodernenergyservicesiswellunderstood(see,forinstance,Tenenbaum,Greacen,Siyambalapitiya&Knuckles,2014;InternationalEnergyAgency,2010)andtheabsenceofmodernenergyservicesisregardedasaserioushindrancetoeconomicandsocialdevelopment.WhileSouthAfrica’selectrificationratesarenotablyhigherthanmostothersub-SaharanAfricancountries1,thecountrystillhasasignificantelectrificationbacklogand,becauseofthis,theassociateddevelopmentaldividendscannotbeclaimed.Relyingsolelyontheextensionofthegridnetworktoconnectunelectrifiedhouseholdswillrequirehugefinancialresourcesandwilltakemanydecadestocomplete–assumingsuchfundsareavailable.Instead,atwofoldapproachwillincreasinglyemerge,ensuringthe extension of the grid in addition to the distributed or‘off-grid’electrificationofmoredispersedandlessaccessiblecommunities.

12SUSTAINABILITY OF DECENTRALISED RENEWABLE ENERGY SYSTEMS
2.1 Definition of DRETs
Forthepurposeofthisreport,distributedrenewableenergytechnologiesaredefinedas:
• ‘off-grid’systemsintermsoftheelectricitynetwork;
• whicharepoweredbyrenewableenergysources,includingsmallhydro,biomass,biogas,solarandwindpower;and
• whichdeliverenergyservicestoendusers.
Whilethesesystemscanbeinurbanareas,theToRindicate that the focus for this report is on areas where thereisnomainselectricity.Therefore,themainbeneficiariesofthesedecentralisedrenewableenergysystemswouldberural,low-incomecommunitieswhoare off the grid.
Therehavebeensignificantdevelopmentsshowcasinglower-costandhigher-powermicro-grids(see,forinstance,theDevergycasestudyinAppendixAofthisreport,emerginginterestina‘swarmelectrification’modelandtheinterestoftheSouthAfricaNationalEnergyDevelopmentInstitute(SANEDI)inmicro-grids).There has also been a resurgence in interest in (green) mini-grids2.So,thedefinitionofDRETsshouldbeonethatisexpandedtoincludeminiandmicro-grids.Anexpandeddefinitionwouldalsosupporttheideathattheobjectiveisaminimumlevelofenergyservicedelivery.Thestrategy(inordertoachievethisobjective)shouldbeasefficientandinnovativeaspossible.

• A supportive policy framework and institutional capacity:Wheregovernmentspromoteaccessinruralareas,itmightincludeprivate-sectorinvestment,powerpurchaseagreementsandactivechampionswithingovernment.Credibleinstitutionswithsufficientcapacityarechargedwithleadinganddevelopingthesector(publicandprivate).Theseactivitiesareintegratedatthevariousadministrativelevels(inSouthAfricathiswouldincludenationalministriesrightdowntolocalmunicipalities).

innovations(forinstance,mobilemoney,light-emittingdiode(LED)lightingandexpended12-volt(V) directcurrent(DC)systems)areintegrated.
• Access to finance:Thisentailsdevelopingappropriatefinancemechanismstopromotetheprovisionofandaccesstorenewableenergytechnologiesandappropriateservicedeliverymodels(fee-for-service,progressivepayment,cashsales,financed).Italsoentailsensuringthatfinancialinstitutionsparticipateintechnologyprogrammes,thatsubsidiesaresmartandeffective,andthataccesstoconsumerloans,aswellasaccesstocapital(concessionaryorcommercial),forparticipatingserviceprovidersisachieved.

Theabovepillarswillgenerallyformpartofasetofrecommendationsorguidesthatseektounderstandandovercometheunderperformanceofrenewableenergytechnologies.Andrightfullyso;theyareall–tovaryingdegreesandinvaryingcontexts–importanttoensuremoreproductiveoutcomes.
Thisreportaddressesthecorescopeoftheassignmentandtheabovepillarsbyreviewingaselectionoflocaland international decentralised renewable energy case studiesandassessingtheseprojectsagainstthecriteriaidentifiedintheToR.
However,inadditiontothefairlystandardisedevaluationtemplate,whatisreallyrequiredisastrategytopromoteandmanagetheperformanceoftheoff-gridsector.Aswillbedemonstratedinthisreport,thereiscommitmentatvariouslevels,includingpolicy,researchanddevelopment,aswellastechnologydemonstrations
andpilots,butthereisnostrategytoensuretherolloutandfuturecontributionsofDRETstoachieveuniversalaccessinSouthAfrica.Forinstance,whileSANEDIisempowered“todirect,monitorandconductappliedenergyresearchanddevelopment,demonstrationanddeployment,aswellastoundertakespecificmeasurestopromotetheuptakeofgreenenergyandenergyefficiencyinSouthAfrica”(SouthAfricanNationalEnergyDevelopmentInstitute,2013),itisnotSANEDI’smandatetoundertakemassrollouts4,whichwouldenableDRETstomakethecontributionthatisexpectedofthem.
Thereisagapinthevaluechain.Thereisadequatepolicy,andthereareorganisationsthatconductresearchanddevelopment(R&D).Whatislackingisamanagementauthority:anentitywithamandatetomanagetheoperationsofDRETsinSouthAfrica;nottoconceptualise,nottoanalyse,nottodemonstrate,butrathertooperationaliseDRETsinSouthAfrica.Itisthisoperationalstrategythatismissing.Tobesure,supportivepolicy,commercialtechnologyenvironmentsandaccesstofinancewillallbepartofthesolution,butwithoutanactiveentitytopromoteandmanagetherolloutofDRETs,thisoff-gridoptionwillnotdeliveronitstrue potential.
2.3 Current policy overview

2.3.1 White Paper on Energy Policy (1998)
SomeimportantfeaturesoftheWhitePaperonEnergyPolicy(1998)(DepartmentofEnergy,1998)thatdirectlyorindirectlysupportDRETsincludethefollowing:
• Perhapsthemostsignificantshiftisthatenergysecurityisnowbeingachievedthroughgreaterdiversificationandflexibilityofsupply.Oneoftheimplicationsisthattheenergysectorisrelyingtoanincreasingextentonmarket-basedpricing.Governmentisplacinggreateremphasisoncommercialisationandcompetition.Competitiveenergymarketsneedsophisticatedregulatoryregimes.
• Globalfinancialmarketsarealsochanging.Privatefinanceisbecomingincreasinglyimportant.Governmentneedstocreatepolicythatattractsinvestment,whileensuringtheachievementofnationalpolicyobjectives.
• Governmentwillpromoteaccesstoaffordableenergyservicesfordisadvantagedhouseholds,smallbusinesses,smallfarmersandcommunityservices.

• Anewapproachtoelectrificationisrequired–aNewElectrificationRoadmap(implementationplan)forSouthAfricawasdeveloped.
16SUSTAINABILITY OF DECENTRALISED RENEWABLE ENERGY SYSTEMS
• In2011,theDoEstartedwithanewinitiativewherealltherelevantstakeholderswereinvitedto participate and agreed on the need for a New ElectrificationRoadmap.
• Toimprovetherateofelectrification,thefollowingbasicelementsarerequired:
– Workfromacommonimplementationplan
– Improvetheefficiencyofimplementers
– Obtain additional funding
– Utilisedifferenttechnologiestodefineaccessto energy
• CabinetapprovedtheimplementationoftheNewHouseholdElectrificationStrategyon26 June2013,basedonthefollowingfocusareas:
– Defininguniversalaccessas97%ofhouseholds(asfullelectrificationisunlikelytobe possible due to growth and delays in the processofformalisinginformalsettlements)
– Theelectrificationofabout90%ofhouseholds through grid connection and the restwithhigh-qualitynon-gridSHSsorotherpossibletechnologiesbasedoncost-effectiveoptions in order to address current and future backlogs
– Developingamasterplantoincreaseefficiencyinplanningandthedeliveryprocesstoensuremoreconnections,includingaworkshopontheimplementationplantowhichallmembersofCabinetwouldbeinvited
• The way forward for the New Household ElectrificationStrategy:
– Adequatefundingforcapitalprojects,managingtheIntegratedNationalElectrificationProgramme(INEP),skillstransfer and training
– ImplementationinlinewiththeMasterPlan5
– Theneedtosolvetheseriouschallengesin the electricity distribution infrastructure (EDI)6;itisdifficulttorunanelectrificationprogrammewhenthenetworkrequiressignificantupgrading
– Theneedtosolvesomeseriousnetworkconstraints;connectionscannotberolledoutinsomepartsofKwaZulu-NatalandtheEasternCapewheretherearelargebacklogs
– More political support for non-grid technologies
– Good cooperation between national governmentandotherspheresofgovernment
Itwouldappearthatthenationalpolicyframeworkislargelyinplace.Additionalpolicy,planningandprogrammeinitiativesreviewedincludethefollowing:
• Non-Grid Electrification Policy Guideline: This documentreaffirmsgovernment’scommitmenttoprovidingaccesstomodernenergyservices,evenin off-grid areas. While it centres on the concession model,italsoopensupopportunitiesforthedevelopmentofoff-gridresourcesinnon-concessionareas.

The guideline addresses issues such as the fee-for-servicemodel,subsidies,theapplicationprocessformunicipalitiesandfreebasicelectricity(FBE).However,thedocumentonlyfocusesonSHSsanddoesnotaddresstheintroductionanddevelopmentof other renewable energy technologies.
• Integrated Resources Plan (IRP): The IRP was intendedasa‘live’documentthatwouldbeupdatedeverytwoyearstocapturethedynamicsofnewopportunities.

• Free Basic Electricity: This was introduced in 2003tofacilitatethedeliveryoffreebasicservicesbymunicipalities,setat50kWhperbeneficiaryhouseholdpermonthforelectricity.Thepolicysoughtwaystoprovidean‘operational’subsidythatwouldenablepoorhouseholdstoconsumemoreelectricityandenjoygreaterdevelopmentaldividends.Theconceptwasextendedtooff-gridenergysourcesaswellthroughtheFreeBasicAlternativeEnergy(FBAE)programme,whichallowedunelectrifiedhouseholdstobenefitfromoperational subsidies by reducing the costs of paraffin,liquifiedpetroleumgas(LPG)andbiofuels,forinstance.Thishashadsome–albeitverylimited–success,andissuesremainaroundthecontinuity of the subsidy and the application process. It would certainly be worth exploring whether a morecontrolledanddedicatedFBE/FBAEsubsidymightbeappliedtoDRETsgoingforward.ItisworthnotingthattheiShackProject(seecasestudiesinAppendixA)hasrecentlymanagedtosecureanFBAEsubsidyfromtheStellenboschMunicipality.
• Department of Trade and Industry (DTI) Solar/Wind Development Strategy: This is a strategy topromotethelocalisationofmanufacturingopportunitiessurroundingtheimplementationoftheREIPPPProgramme.WhiletheremightbesomebenefitforDRETinitiatives,thisstrategyisdesignedtofeedoffthelarge-scaleinvestmentandhardware/infrastructure opportunities associated with the REIPPPProgramme.Indeed,thelarge-scalefocusoftheseinitiativeswouldsuggestlargeproducts(sizeandoutput),whichmaynotbecompatiblewiththesmaller-scalerequirementsofDRETs.
• Working for Energy (WfE):TheWorkingforEnergyProgrammefocusesontheprovisionofenergyandotherrelatedinterventionstoimprovethelivelihoodofpeopleinenergy-starvedcommunities.Theinitiativeplacesemphasisonlabour-intensiveoptions,targetingemploymentopportunitiesforwomen,youthsandpeoplewithdisabilities.WfEisacross-cuttinginitiativethathasthepotentialforextensivepublic-andprivate-sectorpartnership,inter-governmentalsynergyandcooperativegovernancewithintherenewablessector.7ThiskindofinitiativeismorealignedwiththeDRETsthatformthefocusofthisresearchinitiative.Anumberoftheseprojectinitiativeshavebeenincludedinthecase studies. It should be stated that WfE is not a policy,butratheraprogramme8.
• National Energy Regulator of South Africa (NERSA) and regulatory participation in off-grid activities: NERSAplaysarelativelyimportantroleintheoff-gridconcessionprogrammewithregardtosettingtariffs.However,thegeneralfeelingamongconcessionairesisthattheRegulatorisnotactivelyinvolvedintheoff-gridprogrammeandisslowtorespondtoanydirectengagement.ThereislittleontheNERSAwebsitetosuggestamandatebeyondtheconventionalgridelectrificationenvironment.Itisimportantforathrivingoff-gridsectorthattheright

5.1.2 Key challenges
Someofthekeychallengesthatneedtobeaddressedinordertounlockthefullpotentialoftheprogrammeincludethefollowing:
Intermittent contracts
During the conceptualisation of the concession programme,itwasintendedthateachofthesuccessfulcompanieswouldinstall50000SHSsoverthefirstfiveyearsoftheprogramme(Zak,2002).Thiswouldenablethecriticalmassthattheconcessions’businessmodelsrequiredandensureamorerobustoff-gridprogramme.Formanyyears,theconcessionprogrammeappearstohavelimpedalong,benefittingfromadditional,yetintermittent,installationcontractsfromtheDoE,aswellastheongoingsupportandcontinuedinvestmentofitsforeignpartners(Nuon/FoundationforRuralEnergyServices(FRES)andEDF/total)22.Collectively,theconcessionaireshaveonlyreceivedsubsidiesforapproximately65000systems23. The installation contracts and associated subsidies are usually issued atshortnoticeandrequirefreneticinstallationsovershortperiods(forinstance,1500systemsovertwomonths)ratherthanlonger-termprocessesthatenablethemoresustaineddevelopmentofinstallationteams,improvedrelationship-buildingwithcommunitiesandlocalgovernmentstructures,etc24.Theintermittentnatureofthecontractsisaresultof,atleastinpart,thewaveringcommitmentoftheDoEtotheoff-gridprogramme,asevidencedfrominteractionsbetweentheDoEandtheauthor.Whileithasdeliveredreasonably

Lack of planning and churn
ThereisnoelectrificationplaninSouthAfrica,nohardandfastmapthatwilldeterminegridandoff-gridareas.While the planning process has been established (municipalitiesareworkingwithEskomandtheINEP),thishasresultedinshort-termandadhocagreementsratherthanalong-termsettledplan.Inaddition,thereisnoagreementbetweenEskom,theDoE,municipalitiesandconcessionairesregardinglong-termgridandoff-grid areas and how the interface between the two should bemanaged;insomeinstances,thereisanecdotalevidenceofconcessionaireshavingbeenactivelyunderminedbyEskom.Thishasresultedinasignificantamountof‘churn’(removalofoff-gridsystemswiththearrivalofthegrid)andverylittlestabilitywithregardtolong-termplanningandtheresultingdisruptiontotheconcessionaires’businessmodels.Thereisacriticallackofspatialandtemporalplanningthatunderminesthe sustainability of decentralised energy access options.Withoutlong-termplanning,energyservicecompaniescannotdeterminethelong-termmarketopportunity and the extent to which they are prepared to invest.

Similarly,municipalitiesdonotseetheneedforalternativetechnologyinterventionsastheycannotmapthe future installation rate and location26.
Technology specifications
Theoriginaltechnicalspecifications,includingNRS052,whichguidedthedesignoftheSHSsinstalledundertheoff-gridprogramme,areoutofdate.Forinstance,thestandardsutilisedCFLsasopposedtoLEDlighting,whichisfarmoreenergyefficient.Thestandardsandcontractagreementswiththeconcessionsneedtobeupdated frequently in order to integrate technology developments,particularlyaroundlighting,storageandpower generation technology27.
Clear communication
Theoff-gridprogrammehasneverbeenwidelyendorsedbyseniorgovernmentrepresentativesina clear and consistent way. If the off-grid sector is expectedtomakeameaningfulcontributiontoimprovingenergyaccessinSouthAfrica,thenitfollowsthatthisexpectationshouldbeopenlycommunicatedbothtotheenergyserviceindustry(publicandprivate)andthehouseholdmarket.IDCOLwouldnothaveachieveditsoff-gridresultswithoutanexplicitcommitmenttothetechnology(SHS)andassociatedprogramme.Similarly,thebiogasprogrammeinNepalwouldnothavefacilitatedtheemergenceof62private-sectorcompaniesintheabsenceofexplicitcommitmenttotheprogramme.InSouthAfrica,provincialandlocalgovernmentrepresentatives,non-governmentorganisationsand–indeed–theprivatesectorwould

• Flawedsystemdesign:
– Households were able to connect large loads,whichtrippedtheentiresystemandnotonlytheirhouseholdconnections.Limitswereneeded–throughsocialsanctionsoftechnologyinterventions(fuses,forinstance)in order to regulate the equity of use.
• Communityengagement:
– Theprojectwas‘parachuted’in,withlimitedcommunityengagement.Itwasestablishedthat this was one of the reasons why thesystemwasvandalised(aswellasperceptionsthatthemini-griddevelopmentwouldpreventthenationalgridfromarrivinginthecommunity).
– Themostsignificantproblemintheareawasthecontaminateddrinkingwater.
• Highcost:
– ItcostR7,76/kWh(2007);Eskom:R0,16/kWh(2007).
– Costwouldnotberecoveredthroughlocalcommunityuseandpayment;instead,it required large capital and operational subsidies.Adequatefinancialplanningwasnotundertaken.
– Storagemadeup70%ofcapitalandoperationalcosts,whichwouldhavebeenarecurring‘operational’cost.
• Inclusion/exclusion:
– No clear boundaries/criteria for households whowereconnectedvs.thosewhowerenot.Anissueoflocallevelplanning,includingcommunityconsultation.

Havingbrieflylookedatthefourcasesabove,successfactorswillnowbeidentifiedthatcanbefoundacrossallfourcases,andwhicharetransferableacrosstechnologies,geographiesandothercontextualelements.
6.4.1 Management: capacity and commitment
All three cases illustrate the absolute necessity of havinghighlycapacitated,committedpeopledrivingimplementation.InthecaseofBangladesh,thisdrivingcapacitycouldbefoundinIDCOL,whereacompletelynewunitwasstaffedbyyoung,highlyqualifiedcommercegraduateswithastrongcommitmenttoseetheprogrammesucceed.OGEwasestablishedbyOxfordMBAgraduateswithsignificantexperienceinsettingupandrunningtechnologycompanies.Ithasaboardofdirectors,aswellasinvestorswhoareleadingauthoritiesintheirtechnologyandinvestmentfields.TheNepalBiogasProgrammeisledbyawell-definedpublic-privatepartnership(PPP)betweentheNepalesegovernment,theprivatesectorandinternationaldonorsandnon-governmentalorganisations(NGOs),withastrongtechnicalrolebeingfulfilledbytheNetherlandDevelopmentOrganisation(SNV).Toyolastoves’foundersarecommittedentrepreneursfamiliarwiththetechnology,theirmarketandglobalcarbonmanagementsystems.

Thereisnorealformulaintermsofwhatthesefinancingarrangementslooklike,orhowtheyareapplied.Inallcases,thereissomeleveloffinancingandcreditinvolved,andmostcasescombinethiswithsubsidies.However,itdiffersacrossregions,technologiesandbusinessmodels.OGEdidnotmakeuseofanysubsidies,insteadoptingforthealreadymentionedfee-for-servicearrangementasaformofcredit;theNepalBiogasProgrammeprovidedacapitalsubsidylevelof30to50%initially,whichhasincreasedto40to60%toensurethatthepoorerhouseholdsarereached.ForIDCOL,capitalsubsidylevelsdecreasedsteadilyovertime,withonlythesmallestofsystemsnowreceivinga20%subsidytoensuremarketpenetrationatthelowestendofthespectrum,whileloansprovidedthroughmicrofinanceinstitutionsfinancedtherestofthesystemcosts.Despitethelackofuniformity,creditandgrantshavebeenusedtolowertherisksandincreaseaffordabilityforallthreecases.Asmart,yetsimplefinancingarrangementthatlowerstheriskforconsumersandotheractorsalongthevaluechainisimportanttoachievescaleandimpact.Inaddition,itisimportantthatthegrantsorsubsidy

WhileSouthAfricahasbeenprovidingcapitalsubsidiestodecreasethecostsofitsoff-gridSHSs(muchlikesomeofthesuccesscases),itappearstohavehadtheoppositeeffect,underminingratherthanpromotingthecommercialsustainabilityoftheimplementingcompanies.Forinstance,solarcompaniesaretiedtothesubsidyinordertorolloutandattaincommercial‘criticalmass’,butthesubsidiesareonlyavailableonaveryadhocbasis,holdingthesolarcompaniesinlessthanoptimalcommercialpositionswithregardtocustomernumbersanddensities.Duetothefactthat80%ofthecapitalcostsoftheSHSsarecoveredbyagovernmentsubsidy,thesolarconcessionaireshavebeentiedintoaverydependentrelationshipwithagovernmentthathaschangeditscommitmenttotheoff-gridsectorrepeatedly.Thesubsidylevelhasalsonotchanged,whichmeansthatcompanieshavebuilttheirentirebusinessmodelaroundaccessingsubsidies.Whengovernment’scommitmenttotheprogrammefalters(whichhappensfrequently),thecompaniesfaceseverefinancialstrain,whichintheendimpactsoncustomerswhoarenotbeingadequatelyserviced.TheconcessionprogrammealsomakesuseoftheDoE(nationalgovernment)toprovidecapitalsubsidies,whileoperationalandmaintenancemonthlyfeesubsidiesaresupposedtobeprovidedbylocalmunicipalities.Inaddition,theprogrammeusesquiteabitofoldtechnology(largesystems,CFLlights,invertersinsomecases,outdatedbatterytechnology)toalargeextentbecausethesubsidiesrequirespecific(outdated)technologies.Ensuringthatthesesystemdesignspecificationsareuptodatewiththelatesttechnologyisacumbersomeandexpensivebureaucraticprocess

Allofthisspeakstotheneedforconsistent,smartsubsidies,policycertaintyandfinancingarrangements.
6.4.3 Technical quality/standards
Theuseofhigh-qualityequipment,inmanycasessupported or necessitated by appropriate (and enforced)technicalstandards,hasledtowidespreadmarketacceptanceandimpact.IDCOLisprobablytheleadingcaseinthisregard,asitsuseofhightechnicalstandards,setandenforcedbyanindependenttechnicalcommittee,hasseenrapidimprovementsinenergystoragesolutions(batteries),continuedsystemimprovementsandreducedcosts,aswellastheestablishmentofalocalmanufacturingsectorbuiltontheneedtoprovideappropriatetechnologiesfortheprogramme’sSHSs.Infact,almostallthecomponentsofIDCOL’sSHSsarenowsourcedlocally,whichwasnotthecaseseveralyearsago.
ForboththeNepalBiogasProgrammeandtheIDCOLProgramme,theuseofresults-basedfinancingaddsanother layer of technical quality control. This allows theseinitiativestonotonlycontrolthecomponentsused,butalsotoassessinstallationqualityandcustomereducationasprerequisitesforsubsidyandgrantdisbursement.Thisshiftstheriskontotheservicecompany,whoneedstomakesureeverythingworks(andcontinuesworking)beforetheincentivesarepaid.

What this shows is that technical quality and standards areessentialsuccessfactors,andtheseneedtobedirectlyrelatedtocustomerenergyserviceneeds,while also being constantly updated. The danger is thatthisissuebecomespoliticised(especiallyinacountrylikeSouthAfrica),leadingtoirrelevanttechnicalstandardsthatareoutofdateandfailtodelivertheappropriateenergyservices57.Inaddition,merelyhavingstandardsisnotenough:enforcingandpolicingthesestandardsisessential.Thisspeakstotheneedforalarge-scaleprogrammewithadequatemomentum(likeIDCOL),whichcanensureadequatemonitoring.Amoreestablishedandregulatedframeworkforoff-gridimplementationinSouthAfricacangoalongwaytowardsachievingthis.

ContrastthiswiththeSouthAfricanexperience,whereservicedeliveryishighlypoliticised,andsupportfortheoff-gridprogrammehasbeenstop-startatbestforthepast10to15years,anditisnotdifficulttoseewhytheoff-gridsectorhasnottakenoffinthecountry.Inaddition,SouthAfricastilldoesnothaveanintegratedelectrificationmasterplan,whichisasignificantandrealriskforcommercialoff-gridoperatorsinacountrywheretheoff-gridsectorisalreadyrelativelysmalltobeginwith.Stabilityofopportunityisessentialtoattractinvestors,andthisrequiresconsistent,unwaveringlong-termgovernmentsupport.TheREIPPPProgrammeisagoodexampleofwhatcanhappenwhenthisisin place.

6.4.5 Integrating new technologies
Animportantfeatureofallfourcasestudiesisconsumer-focusedtechnicalagility:thewillingnessandabilitytoconstantlyintegrateinnovationsthatreducecostsandenhanceservicedelivery,basedoncustomerneedsandtechnologyimprovements.This,forexample,referstotheintegrationofmobilephonetechnology,whichisusedtoaddressissuessuchaspayment,customercommunication,first-linemaintenance,etc.OneseesthishappeningthroughthehighlyrespectedTechnicalStandardsCommittee,aswellastheOperationsCommittee,forIDCOL’sinitiativeinBangladesh,wheretechnicalexperts,servicecompanies,technologymanufacturersand

This is one of the reasons thattheIDCOLProgrammehasseensuchdramaticcostreductionsandincreasedservicelevels.InEastAfrica,OGEhasintegratedhigh-endtechnologyinsuchawaythatitmakesthesystemsrobustandenablesthebusinessmodeltowork.Thisisthecasewithintegratingmobiletechnologyforservicepaymentsormobilesystemsmonitoring,forexample.InNepal,SNVhasbeeninstrumentalinensuringthatfeedbackisbeingintegrated,withthedesignevolutionofdigestersbeingaconstantfeatureoftheprogramme(forinstance,lookingatflowregulationforutility-typemanagementmodelsandhavingtechnicalteamstoupdateoperationsgenerally).
SouthAfricahasunfortunatelynotseemthesamelevelofinnovation:mostoftheoff-gridsystemdesignshailfromtheproject’sinceptionperiod(circa2000),which,althoughithasbeenupdated,hasnotkepttreadwiththepaceofinnovationintheoff-gridenergysector.Asaresult,customerpaymentlevelsarelow,customersatisfactionislimitedandpublicsupportiswavering.

TheSouthAfricanconcessionmodelhasseentheopposite happening.

Astouchedoninthecommercialissuesdiscussedabove,policyisanoverarchingissueindiscussionson the sustainability of DRETs. It is really quite straightforward–withoutastrongandabidingpolicyframework,privateinvestmentwillnotbeinterestedandthe sector will not raise the necessary capital in order toachievetheoutcomes.Policyneedstobewhatisreferredtoas‘loud,longandlegal’(Hamilton,2009).
• Long:sustainedforadurationthatreflectsthefinancinghorizonsofaprojectordeal.

• Legal:aclear,legallyestablishedregulatoryframework,basedonbindingtargetsorimplementationmechanisms,tobuildconfidencethattheregimeisstable,andcanprovidethebasisforlong-life,capital-intensiveinvestments.
Withinthispolicyframework,attentionneedstobepaidtoprecisioninpolicydesign.Itisnousehavingapolicythatdoesnotaccommodatetheprevailingapproachestoenergyservicedelivery.Forinstance,thepolicyshouldaddressthe‘scalability’ofprojects,aswellasthemorecurrentpaymentmethodologies,financingandsubsidyrequirements.Policysetstheinstruments,ambition,scenesandcommitmentsrequiredtoachievethetargetedoutcomes.Therearemanyissuesthat need to be addressed in an appropriate policy framework.Giventhatthereisaseparateanalysisonthepolicyrequirementsforfacilitatingmoreproductiveoutcomes,thekeyissueswillbementionedbrieflyunderlimitations,buttheseissueswillbeaddressedinmoredetailunderthespecificreviewsectionrelatingtopolicy.Thekeyconsiderationsincludethefollowing:

• Atechnicalstandardscommitteeshouldfrequentlyreviewandadoptsuitableexistingstandards.
• StandardsbuildmarketconfidenceintheperformanceofDRETs.
• Technical standards address any installer and end-user health and safety issues.

Strategically,itisproposedthattheagencyassumestherolloutof‘operations’bypromotingandmanagingoff-griddevelopmentswithinthecountryandlinkingwith(notduplicating)currentresearch,developmentanddemonstrationactivities.
10.2 Establish a grid network master plan
