Costco Wholesale Corp. (NASDAQ: COST) has partnered with Trinity Energy, a provider of turn-key sustainable energy solutions, on deployment of a modular, off-grid electrified energy system at the Costco warehouse store in Norwalk, Connecticut.

According to the companies, the microgrid system is designed to fully power Costco’s standalone tire center using a modular solar and battery microgrid that generates, stores, and delivers energy on-site. The installation can deliver up to 2 MWh of power per day and enable the retailer’s tire center to run entirely off the grid while supporting Costco’s broader goals around sustainability and resilience.

“Energy should be treated as a necessary, finite resource as opposed to an expense or balance sheet charge,” said Shay Reed, assistant general merchandising manager at Costco Wholesale. “Our work with Trinity shows how energy can become a real asset that secures our operations, aligns with our sustainability goals, and reduces risk. This partnership is helping us lead the way toward greater energy independence.”

“This isn’t just about providing clean energy, it’s about redefining energy as a strategic asset,” added Darin Leonard, President of Trinity Energy. “We’re enabling our partners to generate and manage their own energy with speed, autonomy, and ethical integrity.”
