3. Need for transitional solutions – e.g. separate feeders in India • Elusive problem – subsidy; excessive pumping; over abstraction; financial loss to utilities • Pragmatic solution - separation of electricity supply to villages and pumps • Outcome - reduced electricity use, recovering water tables, improved power supply to domestic users, higher yields
4. • India has 130,000 GW of installed pumping capacity in electric and diesel tube wells • Shifting to a solar power source could reduce India’s Greenhouse Gas emissions by up to 6% • Threat of over-use and resource depletion • Adopt a hybrid approach – solar irrigation + feed in tariff • Provides a ‘nexus’ solution Agricultural livelihoods - Energy - Water - Climate Solar irrigation - the ‘opportunity’ and the ‘risk’ Solar pumps offer 2800-3000 hrs/yr of top quality, day-time power, free.
5. SPaRC: You cannot charge Rs 7/unit of grid power to farmers; BUT YOU CAN PAY THEM Rs 7 FOR THEIR SURPLUS SOLAR POWER WHICH THEY DO NOT USE TO PUMP WATER MGVCL’s 25 year Power purchase guarantee at Rs 4.63/unit Project Green Energy Bonus: Rs 1.25/kWh Project Water Conservation Bonus: Rs 1.25/kWh Total Feed in Tariff: Rs 7. 13/kWh Earned Rs 90,000/ in 4 months IWMI CCAFS Pilot: Solar Power as a Remunerative Crop
