6 India s Energy Conundrum India s Per Capita Electricity Consumption (2010) : 85 Watts per person World Average Per Capita Electricity Consumption : 313 Watts per person 60% of India s grid electricity comes from coal, which is in short supply 10% of India s 6 lakh villages yet remain grid inaccessible Of the remaining 90% villages, most face blackouts up to 18 hours everyday Households with access to electricity 4.5 out of every 10 houses in rural areas are unelectrified 6 Source : Argus Reports,MStatistics, Govt. of India, CIA Press Information Bureau, Govt of India. Kerosene is used for home lighting in nearly half of all rural homes

8 Hybridised Distributed Generation However, not all energy sources are perfectly suitable for a decentralised grid purpose Grid Power Solar Renewable Biomass Power DG Sets Flexible Perennial Cheap Abundant Low maintenance Energy Security Modular Flexible Generation Less Capital Intensive Ready Availability Cumbersome Pilferage problems Capital Intensive Difficult to Harvest Limited resource Polluting Costly in the long term The True cost of electricity delivery is even high compared to the actual price that we pay due to high capex in distribution infra/kwh used, high opex/kwh used and trasmission loss due to longer lines/kwh used Hybridised Distributed Generation holds the key to solving all these shortcomings. 8 Solar Field GRID Balance of Plant Biomass Generation Steam Turbine, Grid Evacuation Equipment

9 Advantages of a Solar-Biomass Hybrid System A hybrid solar-biomass system is inherently superior as it utilises the best features of both renewable forms of energy Optimum Land Area Utilisation A hybrid system, by design uses land more optimally than conventional solar renewable energy sources Less Capital Intensive Than conventional solar systems with similar autonomy A Solar-Biomass hybrid plant has easier vistas for integration into other processes that use hot water/ pressurised steam Cold Storage Comfort Cooling Space Heating Better Energy Security Flexibility in Electricity Generation Creation of Local Job Opportunities 9

10 The Shive Project : Broad Outlook Shive is the typical Indian village in Khed taluka, Maharashtra, 57 kms from Pune The project was funded by the Department of Science and Technology, Govt. of India Population : 3500, 500+ households Agricultural Economy Water Availability Abundant radiation Poor Grid Connectivity Daily blackouts of up to 14 hours Solar field Scarce industry Labour migration No Cold Storage Wastage of agricultural produce 10
