Webinar 9 | Dec-16 | Productive loads as anchors in rural mini-grids

  1. 1. Making Off-Grid Rural Electrification Work PRODUCTIVE LOADS AS ANCHOR IN RURAL MINI GRIDS Mlinda Case Studies Source:MLinda
  2. 2. BACKGROUND 2 • Not-for-profit • Operational in India from 2010 • Environmental agenda – Reduce GHG emissions, Production and Consumption of environmentally positive goods, Improve energy efficiency of GDP of the villages • 310 pico /micro grids in 5 districts of West Bengal and Jharkhand • 9 mini grids in Gumla, Jharkhand Source:MLinda
  3. 3. BACKGROUND- MINIGRIDS IN RURAL AREAS 3 • TYPES – SIZE, TECHNOLOGY, CONNECTIVITY TO MAIN GRID, AC/DC • ECONOMIC STATUS OF THE VILLAGE – ABILITY AND WILLINGNESS TO PAY, ENTREPRENEURIAL SPIRIT, OTHER DEVELOPMENT INDICES • CONNECTIVITY – ROAD COMMUNICATIONS, TELECOM, ACCESSIBILITY • NATURAL RESOURCES – WATER, SOIL, TERRAIN, POTENTIAL FOR COMMERCE • HUMAN CAPITAL Source:MLinda
  4. 4. SUSTAINABILITY OF RURAL MINI GRIDS` • TYPES OF LOADS – DOMESTIC, COMMERCIAL AND PRODUCTIVE • DAY VS NIGHT LOADS • BREAKDOWN OF COSTS • STORAGE, METERING, TRANSMISSION – CONTRIBUTE THE LION’S SHARE • CONNECTED LOAD AND UTILISATION • VOLATILITY OF DOMESTIC LOADS • NATURE OF COMMERCIAL LOADS – MARKETS, TELECOM TOWERS, POULTRY SUSTAINABLITY OF MINI GRIDS
  5. 5. PRODUCTIVE LOADS • CONTRIBUTION TO INCOME LEVELS AND VILLAGE GDP • FARM / NON FARM • SEASONALITY • STABILITY • DAY/ NIGHT LOADS • MILLING, CRUSHING, PUMPING • WINNOWING, THRESHING • HEATING/COOLING PRODUCTIVE LOADS
  6. 6. PRODUCTIVE LOADS • Rural, Tribal, Remote • Sophisticated, Three Phase, AC • 24x7 Energy, Diesel back-up • Smart, pre-paid metering • Time of day tariffs • Size 20 to 40 kWp • Ground Mounted • Design - 80% Capacity Productive Loads such as irrigation pumps, rice hullers Mlinda Mini Grids
  7. 7. SUSTAINABILITY OF RURAL MINI GRIDS` • Case Study A – Small grid connect village with domestic and productive loads but no commercial loads • Case Study B – A remote off grid village with domestic, productive and commercial loads Case Studies – A & B
  8. 8. CASE STUDY ‘A’ – ARANGTOLI VILLAGECASE STUDY ‘A’- ARANGTOLI VILLAGE
  9. 9. CASE STUDY ‘A’ – ARANGTOLI VILLAGE • GRID CONNECT VILLAGE 26 km FROM GUMLA TOWN • SMALL VILLAGE WITH 45 HOUSEHOLDS, FERTILE FARM LAND, RIVER WATER AVAILABLE 10 MONTHS IN A YEAR • NO COMMERCIAL LOADS, LIMITED DOMESTIC APPLIANCES • PADDY IS MAIN CROP, VEGETABLES AND PULSES GROWN • ENTERPRISING FARMERS • PLANT SIZE – 22.5 KW • CONNECTED PRODUCTIVE LOAD – TWO LARGE IRRIGATION PUMPS, ONE RICE HULLER, SIX SMALL PUMPS (19 KW) CASE STUDY ‘A’- ARANGTOLI VILLAGE
  10. 10. CASE STUDY ‘A’ – ARANGTOLI VILLAGE • MAX UTILIZATION - 40 / 75 kWh per day • SEASONALITY – IRRIGATION 7 MONTHS, RICE HULLING 9 MONTHS CASE STUDY ‘A’- ARANGTOLI VILLAGE
  11. 11. CASE STUDY ‘A’ – ARANGTOLI VILLAGE HOW DO WE REACH COMMERCIAL SUSTAINABILITY? PUMP GROUPS, HULLER GROUPS, CAPACITY BUILDING, LINK TO MARKETS, EVOLVE INNOVATIVE BUSINESS MODELS, CONNECT NEIGHBOURING VILLAGE CASE STUDY ‘A’- ARANGTOLI VILLAGE
  12. 12. CASE STUDY ‘B’ – NARATOLI VILLAGECASE STUDY ‘B’- NARATOLI VILLAGE
  13. 13. NARATOLI VILLAGE – CASE STUDY ‘B’ • OFF GRID VILLAGE • PLANT CAPACITY – 22.5 kWp • 80 HOUSEHOLDS, ENTERPRISING COMMUNITY, FERTILE FARM LAND • RIVER, PONDS IN VICINITY, 11 MONTHS AVAILABILITY OF WATER • CONNECTED COMMERCIAL / PRODUCTIVE LOADS 30 kW - 58 POULTRY UNITS, TWO LARGE PUMPS, TWO RICE HULLERS, 6 SMALL PUMPS CASE STUDY ‘B’- NARATOLI VILLAGE
  14. 14. NARATOLI VILLAGE – CASE STUDY ‘B’ • PEAK UTILIZATION – 50 /75 kWh • SEASONALITY – IRRIGATION PUMPS 7 TO 10 MONTHS, RICE HULLERS 9 MONTHS CASE STUDY ‘B’- NARATOLI VILLAGE
  15. 15. NARATOLI VILLAGE – CASE STUDY ‘B’ HOW DO WE REACH COMMERCIAL SUSTAINABILITY? OTHER POTENTIAL LOADS, GROWING DEMAND, PUMP AND HULLER GROUPS, POULTRY GROUPS INNOVATIVE APPLICATIONS CASE STUDY ‘B’- NARATOLI VILLAGE
  16. 16. SUMMARY - LESSONS LEARNT • WATER PUMPING IS A UNIVERSAL ANCHOR LOAD IN RURAL AREAS • EXISTING DIESEL / FOSSIL FUEL BASED MACHINERY TO BE REPLACED BY EQUIVALENT ELECTRIC MACHINES • INNOVATIVE MECHANISMS SUCH AS SHARING METERS BY FORMING GROUPS, HEATING AND COOLING APPLICATIONS CONTRIBUTE ENORMOUSLY • PRICING OF TARIFFS SHOULD BE SO DESIGNED TO MAKE IT A VALUE PROPOSITION FOR THE CONSUMERS VIS-À-VIS STATUS QUO SYSTEM • UTILISATION CAN BE INCREASED IF IT CONTRIBUTES TO NOT JUST THE VILLAGE ENTREPRENEUR’S PROFITS BUT BENEFITS THE WHOLE VILLAGE • PRODUCTIVE ENERGY ACCESS MUST BE MAINSTREAMED WITH OTHER DEVELOPMENTAL GOALS SUCH AS HEALTH, EDUCATION • INVOLVEMENT OF WOMEN IN PRODUCTIVE BUSINESSES PAYS HUGE DIVIDENDS SUMMARY – LESSONS LEARNT
