Case II: All the Energy Demand is met by Local Wind Power Plant<br />
Installation<br />
Calculations:<br />
• 1 KW WTG generates around 3 – 3.2 units (KWh) per day. (DOT 2008) <br />
• Average units generated / day = 3.1 kWh<br />
• Total requirement in our model = 90.9 kWh<br />
• => Capacity of Wind Turbine to be installed = 90.9/3.1 = 29.3 ~ 30 kWp<br />
Case III: All the Energy Demand is met by Local Biomass Power Plant<br />
Installation<br />
Calculations:<br />
• Human excreta of 150 users of community latrine will produce = 150/35 =<br />
4.3 cum biogas<br />
• 4.3 cum biogas will generate (1/0.21)*4.3 = 20.5 kWh<br />
• Capacity needed = 90.9 kWh. Demand Unmet = 90.9-20.5 = 70.4 kWh<br />
• 70.4 kWh is to be met by other bio-mass, which implies 14.8 cum of biogas<br />
• 14.8 cum of biogas implies (20/1600) = 185 kg of biomass.<br />
• 4 cum is generated by 10-12 heads (MNRE 2006). 14.8 cum of biogas will<br />
be generated by the excreta of 41 cattle heads. This may be possible.<br />
• Hence, mixed waste digester required. => 90.9/24 = 3.8 kW ~ 4 kWp<br />
capacity is required.<br />
Case IV: All the Energy Demand is met by the Proposed Local Alternative<br />
Energy Solution Hybrid Power Plant Installation<br />
<br />
<br />
Calculations:<br />
• 1.2 kWp of Biomass plant is taken, which can be managed with the<br />
population on 150 users and assuming additional agricultural / animal<br />
waste equivalent to that of 35 users. This will generate 24 kWh.<br />
• Required Units = 90.9 – 24 = 66.9 ~ 67 kWh.<br />
• The rest are generated by Wind of 13 kW and Solar of 7 kW capacity.<br />
• This implies Wind to Solar ratio as 1.85, which is greater than 1.
