25kW hybrid Pilot project
Proposed pilot project size: 25kW hybrid
Two 10kW Wind turbines (3.5 m long blades)
5kW Solar PV system
96000Whr battery storage
Expected power output:
At wind speed 5.5 m/s : 42000 kwh/year ; 6 m/s : 45200 unit
Solar 5.2hr/day/300 days: 7800 kwh/year
Total: 50,000 kwh/year; 135 kwh/day
Proposed demand meet:
24/7 power supply to 5KW load : 120 kwh/day
8 hours continuous supply to 15KW load
Surplus electricity 15kWh/day to Households
Value Propositions
Reliable uninterrupted clean electricity
Electricity price up to 30% cheaper compare to diesel electricity
No hassles for procuring and storing diesel or maintaining the diesel generator
Use WindMade label on end products, eg tea, cardamom for premium pricing
Reduced carbon emissions and noise pollution
Electricity access to communities
Secures livelihoods of more than 5000 households
Create local jobs
Revenue Streams: Mangmalam tea
estate
Tier based fixed pricing:
Anchor to pay Rs 35/unit (90% of supply): Rs 1533000/year
Households Rs 50/month/household (2watt* 5 LED bulbs* 5 hours) (10% of supply): 300 HHs Panchami Bazaar- Rs 180000/year
Annual revenue: Rs 1713000
