Seven-Eleven Japan begins reusing power units via remanufacturing

Seven-Eleven Japan is launching its “Remani Cubicle” initiative together with Itochu Plantech Corporation and Panasonic Electric Works. It is a resource circulation scheme designed to remanufacture high-voltage electricity distribution cubicles removed from closed or renovated stores. The convenience store operator extracts key components such as transformers from decommissioned cubicles, reconfigures them to match new store specifications, and reinstalls them in as-new condition across its retail network.

High-voltage cubicle substations are essential infrastructure for delivering electricity to convenience store sites. Previously, directly redeploying used cubicles from closed or reconstructed outlets to new store locations is difficult because of different electrical specification requirements. As a result, retailers frequently installed brand-new cubicles at new sites while discarded units remained underutilised, presenting an ongoing challenge for equipment life-extension in commercial operations.

To resolve this issue, the three companies established a four-stage management framework. Under the new system, Seven-Eleven Japan selects eligible stores for equipment recovery, while Itochu Plantech designs the overall scheme and manages collection, refurbishment, and redeployment operations. Panasonic Electric Works oversees the business management and technical support for the remanufacturing work, which is carried out by its affiliated companies to inspect returned units, extract viable transformers, and rebuild the equipment to meet specific store layouts.

The scheme not only reduces consumption of raw materials and lowers environmental impacts, but also provides operational flexibility for a more stable supply of critical power hardware for store developments.
