Costco partners to take DC off the grid with independent, on-site energy system
Costco Wholesale Corp. is pioneering energy energy independence at its distribution center in Port St. Lucie, Fla.
The warehouse club giant, in partnership with Trinity Energy, has taken the center off the grid with the launch of an independent, on-site energy system. The solution, which combines solar power, battery storage and electric fleet charging into one integrated platform, is capable of generating enough power to ensure 24/7 energy reliability for all mission critical energy loads, including data centers and other technology that cannot tolerate outages.
Additional benefits to Costco include significant reduction of energy costs long-term, IRA tax credits for solar/energy storage programs and avoidance of rising utility rates. It also provides the company with a turnkey way to meet organizational sustainability, impact and net zero goals. The system powers the entire facility, including all building equipment, allowing evaluation of usage for critical loads such as lighting, refrigeration, EV charging and HVAC.
“By investing in this integrated on-site energy system, we strengthen the reliability of our Port St. Lucie facility while avoiding additional burden on the utility grid,” said Shay Reed, certified energy manage at Costco Wholesale. “This approach supports our continued growth, reduces strain on the broader grid during peak demand, and helps preserve energy resources for the surrounding community.”
The newly commissioned independent energy infrastructure is designed to establish a new model for how large facilities such as large hyper-scale data center operators and major logistics/warehouse operators can take greater control over their energy. Businesses can operate with reliable, self-directed power while still supporting the broader energy system.
The fully integrated solar and battery platform was installed significantly faster than installing a traditional energy backup system from local power providers, enabling Costco to accelerate its operational readiness, bypass lengthy grid interconnection queues and permitting delays, and benefit from substantial cost savings, according to Trinity.
“Kudos to Costo Energy for having the vision to invest in a forward-looking solution that will reap benefits year-round,” said Gonzalo Stabile, VP, design and engineering at Trinity Energy. “For a distribution center of this scale, uninterrupted power is essential to maintain inventory integrity, logistics flow, and overall operational efficiency. Our independent on-site energy infrastructure enables businesses to maintain continuity during grid disruptions, better manage peak demand, and stabilize long-term energy costs.”
