Costco Wholesale is going off grid in launching an independent, on-site energy system at its Port St. Lucie, Florida distribution center.

It has partnered with Trinity Energy (Trinity), a provider of integrated operating systems for sustainable energy solutions, to deploy a fully integrated solar and battery platform to replace the traditional energy backup system from local power providers, according to a press release.

The energy independence solution generates enough power to ensure 24/7 energy reliability for all mission critical energy loads, including data centers and other technology that cannot tolerate outages.

Data collected from the platform allows Trinity to provide insights into usage patterns, offering further energy savings through change management.

"As our operations continue to grow, it's important that we expand responsibly and act as a good partner to the communities we serve," Shay Reed, AGMM, CEM at Costco Wholesale, said in the release. "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. This approach supports our continued growth, reduces strain on the broader grid during peak demand, and helps preserve energy resources for the surrounding community."
