Presentation made at 3rd Northeast Connectivity Summit,2016 on Way forward for solar and wind power in NE India by Prof.N.K. Koka, CEO, KNK Renewables

1. North East Connectivity Summit
2016 Agartala, Tripura 2016

2. Why North-East should look for renewable energy?
 Green economy
 To meet the peak demand of power for consumption
months.
 Mitigate greenhouse gas emission (Co2) & control Climate
change
 Mix energy system for energy security & sustainable
development
 Prevention of environmental damage from large
hydropower which will disturb the ecosystem and
hydrology.

3. North –East on its way to support and mitigate
global concerns for climate change by
 Providing electricity for rural households/ artisans to make them
less dependent on fuelwood.
 Afforestation (60% forest coverage at all times to come in
constitution of North-East)
 Diversify energy to renewable sources
 Encouraging electric vehicles for transportation
 Community forest (CF). The CF Program in North East seeks to
strengthen the link between people and forests and can make a
significant contribution to livelihood improvement,
environmental conservation and sustainable use of forests.

6. Why you need Solar + Wind : Hybrid System ?
1. Hybrid Power Plant Generates Electricity 24X7 & 365 days a year.
2. When you need more energy generation from limited Roof Top Space.
3. Freeze your Electricity Bills for 25 Years.
4. Cut-in wind speeds at 2m/s and Cut-out wind speeds at 18.5m/s
5. Appropriate for ON-GRID & OFF-GRID applications.
6. Higher Power Density / Square Foot
7. Scalable Hybrid System from KW to MW
8. You can track the electricity generation data at the comfort of Laptop /
Mobile through SMS & Email alerts.

Notes
• Wind is variable, but can help stabilize/smooth out daily production
output of PV
• Total daily production is less variable when wind is present
• Wind power offsets lower output due to from temporary cloud cover
