Facility Overview

Operating in Rajasthan, India, this cold storage and logistics hub provides commercial multi-commodity refrigeration for agricultural produce and pharmaceuticals. Running heavy ammonia chilling compressors 24 hours a day in high ambient temperatures, energy costs comprised nearly 40% of overall operating expenses with a monthly utility bill of ₹71.2 Lakhs.

The Challenge

  • High Ambient Heat Base Loads: Extreme desert ambient temperatures required non-stop compressor operation.
  • Peak Heat Grid Surcharges: Afternoon temperature spikes required maximum chilling capacity during expensive peak tariff windows.
  • Energy Cost Pressure: Utility power bills accounted for 40% of total operational cost, depressing gross margins.

The Solution

OnLoop Energy deployed a turnkey 3.3MW Wind-Solar Hybrid System designed to handle heavy refrigeration loads continuously.

  • 24/7 Wind Power Generation: High hub-height wind turbines power nighttime chilling operations.
  • High Irradiance Solar Array: Generates maximum daytime power during peak ambient heat hours.
  • Unbroken Thermal Security: Captive hybrid power delivers continuous energy for constant temperature control across high ambient heat shifts.
