Reiner Lemoine Institute Research focuses: • Integrated energysystems • Optimizationofenergysystems • Energytransitionprocesses • Off-gridenergysystems • RE-mobility • Integration ofrenewableenergiesintomobility • Renewableenergytechnology • Small wind power Reiner Lemoine Founderofthe Reiner Lemoine-Foundation Scientific researchfor an energytransitiontowards 100% renewableenergies
Renewable Energy Mini-Grids Mini-gridsconsistofat least • one energy generator, • one energy storage, • one control unit, • one consumer load and • at a capacityrangeof kW – MW • Mini-grids offer ideal conditions for a grid independent electricity supply.
Motivation forthe Country Ranking • renewableenergybased mini-gridsare a keyelementfor rural electrification • sustainablebusinessmodelsareneededforsupplyinghundredsofmillionsofpeople • comparisonof all countries is a helpfulindicatorforplayers in thefield
Methodforthe Country Ranking • identificationofmaincriteria and respective sub-criteria • market potential • political and financialenvironment • exclusioncriteria • electrificationratesover 95 % and lessthan 200,000 people in rural areaswithoutelectricity • high politicalinstability • verylowdieselprices • weighting and scoringofeachcriterion • criteria not included • noquantificationpossible • not available on a global scale
ConsequencesofExclusionCriteria: Electrification electrification rate > 95 % and rural population without electricity < 200,000 people 98 countries excluded
ConsequencesofExclusionCriteria: Travel Warning travelwarningby German MinistryofForeignAffairs (April 2012):

Resultsofthe Country Ranking: All Criteria • Good political and financial environment combined with high electrification needs are to be found especially in South and East Africa.
Resultsofthe Country Ranking: Sub-Criteria • Key insight: • most top countries ofmarket potential showlowrankingforpolitical and financialenvironment • and viceverca Market Potential Political and Financial Environment
Resultsofthe Country Ranking top 10 countries:
Rwanda – Summary Country Profile focussingenergysector, rural electrificationandinvestmentpossibilities • in general: • large market size • very good financial environment for foreign investors • energy sector: • urgent needs to expand capacities, much imports, high tariffs • target: 1,000 MW electric power capacity in 2017 (90 MW in 2011) • investment in energy production with methane gas (large potential in lake Kivu), hydro power, geothermal and solar power • in terms of renewable based mini-grids: • very low rural electrification rate • independent power producer are allowed to work on- or off-grid • “social tariffs need to be put in place to cater for the affordability of rural citizens” [pictures: WikimediaCommons]
