PowerFlex Delivers Cost-Saving Solar Solutions Nationwide for Preferred Freezer Services

As one of the nation’s largest cold storage warehouse providers, Preferred Freezer Services has more than 35 facilities in operation across the U.S. Founded in 1989, the company has since expanded internationally, with warehouses in China and Vietnam. Preferred Freezer has partnered with PowerFlex to complete several rooftop solar systems in Illinois, California, Massachusetts and New Jersey.

The Challenge

Reducing Energy Costs for High-Demand Cold Storage Facilities

Preferred Freezer Services operates energy-intensive facilities that require reliable, around-the-clock power to maintain optimal storage conditions. With a growing network of sites across multiple states, the company faced the challenge of managing high electricity costs while also seeking ways to reduce its environmental impact. Preferred Freezer needed a solution that could deliver significant operational savings and support its commitment to sustainability, all without disrupting the critical operations of its nationwide cold storage network.
