Why Wind Energy Works in Kolkata
Kolkata sits on the Gangetic delta with moderate but consistent winds. Annual averages range from 3-5 m/s, with strong southerly sea-breeze influence and monsoon winds blowing in from the Bay of Bengal. That makes Kolkata a good fit for Windora's vertical axis wind turbines, which start generating at just 3.5 m/s.
- CESC tariffs among India's highest (₹9-14+/unit) — fast payback
- Cyclone-rated installation (Bay of Bengal cyclone zone)
- Strong monsoon winds (June-Sept) when solar drops 60-70%
- Tech sector growth in Salt Lake / Rajarhat / New Town
- Coastal humid environment — handled by our marine-grade coatings
Real example: A 5 kW Hybrid on a New Alipore bungalow generates ~11,000 kWh/year — cuts a ₹12,000 CESC bill to ~₹2,500. Payback 4-5 years.

FAQ — Wind Turbine Kolkata
Will it survive a Bay of Bengal cyclone?
Yes — our turbines are rated to 55 m/s survival winds (cyclone-grade). Automatic over-speed protection brakes the rotor when winds exceed safe operating limits. We've installed across cyclone-prone West Bengal coast successfully.
How does Kolkata humidity affect equipment?
All Kolkata installations include marine-grade coatings, stainless hardware, and sealed IP65 generators. Designed for humid coastal environments.
Can I get net metering with CESC?
Yes — West Bengal has an active rooftop renewable net-metering policy. We handle the CESC/WBSEDCL application end-to-end.
