High-ROI Cold Storage Solar Case Study: Solar Only vs. Solar + BESS Financial Analysis for 150,000 SF NJ Refrigerated Warehouses
This cold storage solar case study analyzes the financial impact of Solar Only versus Solar + BESS for a refrigerated warehouse, including energy savings, IRR estimates, demand charge reduction, and long-term ROI.
Rising electricity prices, growing demand charges, and 24/7 refrigeration loads are forcing many refrigerated warehouses and cold storage operators to rethink their energy strategy.
This Cold Storage Solar Case Study outlines how a mid-sized refrigerated warehouse could significantly reduce operating costs through:
- Commercial rooftop solar
- Battery energy storage systems (BESS)
- Demand charge reduction
- Smart energy management
- Long-term electricity cost stabilization
For cold storage operators, energy is not optional — refrigeration systems run continuously, making these facilities some of the best candidates for commercial solar and battery storage projects.
At AmeriSol Energy Solutions, we help commercial and industrial facilities evaluate customized solar and energy storage strategies that maximize long-term ROI while reducing operational risk.
Facility Overview
Example Facility Profile

| Facility Type | Refrigerated Warehouse / Cold Storage Facility |
| Building Size | 150,000 SF |
| Location | New Jersey |
| Utility Provider | PSE&G |
| Annual Electricity Usage | 2,850,000 kWh |
| Average Monthly Utility Bill | $48,000–$62,000 |
| Peak Demand Charges | High |
| Roof Type | Flat Commercial Roof |
| Operating Schedule | 24/7 |
Cold storage facilities typically operate around the clock due to refrigeration, compressors, air circulation systems, and temperature-sensitive inventory requirements.
This constant energy demand creates a strong opportunity for:
- Large commercial rooftop solar systems
- Peak shaving strategies
- Battery storage integration
- Demand charge reduction
- Long-term electricity savings
Why Cold Storage Facilities Benefit from Solar
High Daytime Energy Usage
Refrigeration systems create predictable and continuous electrical loads during daytime utility peak periods.
This makes solar generation highly effective because the facility can consume a large percentage of the solar power directly on-site.
Large Rooftop Availability
Most refrigerated warehouses have:
- Large flat rooftops
- Minimal rooftop obstructions
- Strong structural layouts
- Excellent solar design flexibility
This allows for larger commercial rooftop systems with strong production potential.
Demand Charge Exposure
Many cold storage operators are heavily impacted by utility demand charges.
Battery energy storage systems (BESS) can help reduce these charges by discharging during utility peak periods.
