Facility Overview

Operating in Ankleshwar, India — a prime chemical industrial hub — this facility produces specialty organic intermediates and specialty chemicals. Operating 24/7 continuous reactors, effluent treatment plants (ETP), and cooling chillers, the facility recorded an average baseline electricity utility bill of ₹29.2 Lakhs per month.

The Challenge

  • Continuous Chemical Processing: Reaction vessels and cooling chillers require 24/7 unbroken power security to prevent runaway reactions.
  • Sensitive to Voltage Fluctuations: Industrial grid trips caused control system resets and expensive batch spoilage.
  • Corrosive Industrial Atmosphere: High chemical fumes prohibited rooftop solar mounting due to rapid panel degradation risks.
  • High Outage Downtime Costs: Averaged 15 hours of grid outage downtime monthly, risking chemical batch spoilage.

The Solution

OnLoop Energy deployed a 1MW Pure Captive Wind Turbine System with anti-corrosion marine grade coatings, situated outside the plant's corrosive vapor zone.

  • 24/7 Wind Power Generation: Direct-drive PMA turbines deliver continuous clean energy around the clock.
  • Perimeter Installation: Placed away from plant chemical exhaust vents for maximum structural longevity.
  • Grid Synchronized Stability: Advanced power electronics stabilize voltage frequency, protecting sensitive process chillers.
