WALKER – Meijer plans to join the sustainability movement by switching all its stores to LED interior lighting by 2021. The change is expected to save the regional retail giant as much as 50 percent annually in electricity charges.

Meijer first implemented an all-LED store in Beavercreek, Ohio, in 2013.

The project launched in June with the company’s 100-plus stores in Michigan. Meijer will “phase in” other locations state by state within its six-state footprint, so the stores can remain open during the installation process.

“Our Beavercreek location served as a great test that led us down the path to planning a full-chain transition across our six-state footprint,” said Rick Keyes, president and CEO, Meijer, said in a press release.

“The lighting quality made possible by LEDs enhances the shopping experience for our customers and the work environment for team members, while significantly decreasing energy usage.”

Meijer earlier implemented other sustainability measures, including constructing energy-efficient buildings, using a low-emissions truck fleet and offering a wide selection of local and sustainable products.
