The use of renewable sources of energy, including solar, wind, biogas, hydro, tidal andgeothermaltechnologies,inplaceoffossilfuelshasemergedasthemostpowerfulwaytomitigateclimatechange.In Zambia, hydroelectric power remains the dominant form of renewable energy. The country’spopulation has increased, resulting in increased energy demands. The low-rainfall patterns haveresulted in continued national electric energy deficit. Scheduled power outages,which last up to15hrs per day, have had negative impacts on homes, business and the economy at large.

2. Overview:The‘RISE’ProjectDr.AmosMADHLOPA(UniversityofCapeTown,SouthAfrica)
Aninternationalresearchteam,ledbyDrAoifeBrophyHaneyfromSSEEandSaïdBusinessSchool,wasawarded funding from theGlobalChallengesResearchFund (GCRF) to investigateinnovativesolutionsforpromotingenergyaccessinsub-SaharanAfrica(SSA),throughtheRenewable,InnovativeandScalableElectrification(RISE)projectfrom1stSeptember2018to29thFebruary2020.
TheGlobalChallengesResearchFund(GCRF)isa£1.5billionfundannouncedbytheUKGovernmentin late 2015 to support cutting-edge research that addresses the challenges faced by developingcountries.GCRFformspartoftheUK'sOfficialDevelopmentAssistance(ODA)commitment,whichismonitoredbytheOrganisationforEconomicCooperationandDevelopment(OECD).
The interdisciplinary research project aims to design integrated, actionable and transferabledevelopmentstrategiesforthelocalrenewableenergysector in sub-Saharan Africa. The research pursuesthree mutually reinforcing areas of inquiry: suitablebusiness models for a competitive local renewableelectrification industry; optimal institutionalarrangements to facilitate the development of theindustry; and enabling community involvement,especiallyinruralareas.Twocontrastingnationalcasestudies, Uganda and Zambia, form the basis of theproject.

3. EnergyaccessinruralZambia:thecommunityperspectiveDr.BothwellBATIDZIRAI(UniversityofCapeTown,SouthAfrica)
ThispresentationfocussedonfindingsoftheRISEprojectCommunityengagementstudywithaviewto sharing five keymessages derived fromundertaking the study in communities in Zambia andUganda.Thestudyundertookanovel community surveyovera sampleof1016respondentsandelicited community views, perspectives, preferences, opinion on community electrification needs,interaction of community members with energy service providers as well as involvement inelectrificationplanningandimplementation.Weidentified5keymessagesasfollows.
First,energyiskeytoimprovingthequalityoflifeinruralUgandaandZambia,butisnotseenasatop-prioritypurchase.This isbecausethereareotherprioritypurchasessuchaseducationwhichimplylimitedabilitytopayformodernenergyservicesdespiteahighwillingnesstopayforelectricity(~86%).

97%ofrespondentsarewillingtopayforelectricityforproductiveusesacrosssectors.Otherkeycommunity challengeswith electrification include poor system reliability, limited access options,insufficientcapacitytomeetneeds,poorservice,technicalproblems,etc.
Third, potential for more productive use of energy exist across all income-generating activities,especially agricultural, small-scale industry, retail and services sectors. Currently only 15% useelectricity forsomeformincome-generatingactivity. Itmakesfinancialsensetouseelectricity forproductive use at current tariffs as the value-add of 1 kWh can exceed1USD for different smallbusinesses, especially in large untapped potential and strong desire to provide cooling services,hairdressing,sewing,cookinginrestaurants,weldingandgadgetrepairing.Fourth,despitevariousinformation channels that exist, end-users are not yet well-informed enough about their energychoicesandfacenumerouschallengeswheninteractingwithenergybusinesses.Lackofinformationand knowledge is a key challenge of community interaction with energy providers and this isattributedtoinadequateoutreachandvisibilitybyserviceprovidersandkeyenergyinstitutions.Only50%ofrespondentsareawareofenergyserviceprovidersoperatingintheirlocalitiesandonly43%are satisfied with energy services. This highlights the importance of relationship building andcommunicationbetweenanynewpotentialenergyproviderandthetargetcommunity.

5. ChallengesofsolarenergyutilisationinZambia:acase studyofKitwe,Zambia
ProsperyC.SIMPEMBA,DicksonCHEMBEandInutuKATOTI(CopperbeltUniversity,Zambia)
Zambia is currently facing a critical power deficit largely due to low rainfall and because of her dependence on hydroelectricity. Many Zambians have felt the impact of this power deficit and are looking for alternative energy sources for relief. We present here results of a case study of solar energy utilization in Kitwe, highlighting the opportunities and challenges in the application of this energy source.
It is evident that power stations in Zambia are reaching their lifespan and urgent need of replacement or
retrofitting. Zambians recognise existing energy challenges, the need to diversify the energy mix and to tap into solar energy for lighting, water heating and small appliances.
Despite Zambia enjoying enough solar irradiancy, solar power utilisation has not received the much needed attention. In Kitwe, CEC has already implemented a 1W solar power plant. Another 40 MW solar power plant has been constructed in Garneton area of Kitwe. There are also some minigrid systems linked to milling. The common solar application in the area are home lighting, water pumping (Saro Agro supplies system), powering small electrical appliances (TVs, radios, phones, shaving machines, etc), water heating and drying. There are various brands of solar systems on the market.
13
Unlike hydro, utilisation of solar energy is not affected by droughts. There is also a desire for people to utilise solar technologies due to heavy load shedding in the country. There is need for appropriate policies to be in place to attract locals to participate in solar energy projects. Also research funding is required to study local materials for local production of solar panels

The problem of electrification
§ Over 80% of unelectrified people in ACP countries live in rural areas:
§ Small-scale projects§ Rural customers with weaker
purchasing power§ Economic challenges and limited
local business development§ Off-grid projects are expensive
and economically risky
§ Big investments require profitable and stable markets:
§ Large-scale electrification projects§ Industrial and urban electrification§ Growing economies, served by
multi-national businesses

Our sample included both electrified and unelectrified households,businesses/entrepreneurs,andcommunityleaders.Thiswasdesignedtoachievegender,incomeandregionalbalanceforasampleof1016respondents.Thekeyresearchoverarchingquestionwas:Howcan communities engage with and contribute to the development of sustainable electrification,especiallyinruralareas?

ThispresentationisanoutcomeofastudysupportedbytheNon-GovernmentalGenderCoordinatingCouncil(NGOGCC).Thestudyshowsthatwomenandchildrenintheprojectsitesarehighlyexposedto the health risks that comewith heavy reliance on biomass energy for cooking and fossil fuel,particularlykerosene,forlighting.Thus,thisassessmentreportprovidesempiricalevidencefortheneedforactorssuchasNon-GovernmentalGenderCoordinatingCouncil(NGOCC)torecruit,trainandsupportwomenentrepreneurstosellcleanenergyproductsintheselectedprojectsitesinordertoincreaseaccesstocleanenergytechnologies.Thiswillreducethehealthrisksthatwomenandgirlsare exposed towhen using biomass sources of energy. This effort will alsomake a contributiontowardsattainingSDG7whichiscallingforaccesstocleanandrenewableenergyforall.
It is thus recommended that both state and non-state actors should promote the supply and commercialization, at community level, of affordable energy saving cookstoves and solar technologies for lighting. There is need to promote animal husbandry and bio digesters as affordable options for clean energy technologies for cooking. Sensitization of rural communities on the use of movable assets as collateral and lobbing with the private sector to pilot the actualization of the movable property Act (collateral registry) to overcome the limitations of access to credit by rural households is critical for success.

9. Technicalplanning:systemsizingandprotectionofresilientstandalonesolarpowerplant-considerationsforcommunityprojectsplanningtomeetenduserneeds
Sebastian NAMUKOLO, Ackim ZULU (University of Zambia)
Off-grid solar-PV supply could be the path for achieving modern energy access in rural areas of Sub Saharan Africa, significantly moving the rural population toward the target of the 7th Sustainable Development Goal. Energy from the PV plants has the desirable attributes of being clean and affordable. Despite these desirable attributes, off-grid PV plants are also prone and susceptible to lightning effects in operation, this situation particularly accentuated in Sub Saharan Africa where there is high lightning activity. To redress this, the general principles of lightning protection are invoked in the design of the PV power supply to stave off the negative effects resulting from the plant being struck by lightning.
This presentation discusses energy access using off-grid PV systems and proposes a design approach which makes the PV plant to be more resilient in lightning-prone regions. Five subsystems of lightning protection in PV-powered plants, which may be selectively applied depending on the results of the risk assessment, are adopted. This proposed approach is expected to reduce outages and downtime of the PV power plant.

Thefinalsessionoftheworkshopwasaplenarydiscussiononhowacademicscancontributetomakinganimpactonruralelectrificationthroughresearchandinterdisciplinarycollaboration.Thediscussionwasframedaroundthefollowingthreeissues:
(i) IdentifyingbarriersthatinhibittheadoptionanddiffusionofrenewableenergyamonglocalcommunitiesinZambia
(ii) Challengesthataffectperformanceorviabilityofsolarenergytechnologies(iii) Wayforward
Participantssharedarangeofinsightsandexperiencesondevelopmentchallengesfacingtheruralelectrificationsector.Highlightsofthediscussionsaresummarisedbelow:
▪ Therewasgeneralconsensusthataccesstoefficientandsustainableenergyservicesleadstoabetterqualityof lifeforlocalcommunities.However,manypeopleinruralareasstill livewithunreliable or expensive power which poses a key barrier to economic development ascommunitiesandpublicfacilitiesremainwithoutaccesstoenergy.Healthclinics,forinstance,arenot able todeliverhighquality of services, schoolsdonot function effectivelywhile localbusinessareequallyadverselyaffected.
▪ There is need to develop appropriate short term and long-term measures to accelerate theadoptionofelectricityservices.Optionsincludetariffrationalisationtoencourageefficiencyandinvestmentinelectricitysupply.Tariffswouldneedtotakeintoaccountthepayingcapacityofespeciallytheruralpoor.
▪ Forminigrids,thebiggestchallengesarepoorpolicies,inadequateregulations,lackofplanningandlackoffinancingforoff-gridentrepreneurs,andlimitedaffordabilityforpoorerhouseholds.Itwasnotedthatbeforetheelectricitycrisis,thegovernmentofZambiahadK22millionwhichcouldhavebeeninvestedinsolarenergy.However,suchinvestmentsarenotmadeasdecisionsintheelectricitysectorappeartobepoliticallymotivated.Thus,investmentdecisionsinthesectorneed tobe groundedon long termplanning and feasibility studies. Itwas recommended thatimprovementsinelectricitysupplycouldbeachievedifZESCOisfreedfrompoliticalinterference.
▪ Itwasalsonotedthataftertheintroductionofpre-paidmeters,ZESCOwasmakingprofit.Butthemoneywaschannelledtootheruses.
▪ DistributedsolarsystemsthatfeedintothegridcouldmakeanimpactonelectricitysuppliesinZambia.Anexamplewasgiven that if eachhouseholdgenerates3kWof solarpower, thenonaverage,300000householdscanfeedin600kWpowertothegrid.However,themainchallengeinZambiaisthatZESCOwouldnotallowthecustomerstoconnecttogridasthiscancollapsethegridsystem.Butwithinnovativesolutionsandmoderntechnologiesavailable,nowisthetimetobe hopeful to introduce microsimulation at ZESCO. The country has many experts from

▪ Innovativebusinessmodels,suchaspay-as-you-gooffergreatopportunitiesforprivatesector-drivenoff-gridelectrification,aslongascountriescancreatetherightinvestmentenvironment.
▪ Another intervention is to allow electricity provider (ZESCO) to supply solar panels, solarinverters and installation to people at a subsidized rate, thereby accelerating the uptake ofrenewableenergytechnologies.
