Solar power systems have been installed at nearly all stores where it is feasible to do so. The next step toward achieving our renewable energy targets is to begin introducing storage batteries.
At the Matsudo store, we have installed a relatively large storage battery with a capacity of approximately 200 kWh, along with rooftop solar panels.
Electricity generated by the solar power systems from sunrise until store opening is stored in the battery and discharged after sunset until store closing to maximize selfconsumption of renewable energy.
In addition, the system is designed to supply enough electricity to allow the store to continue selling disasterpreparedness supplies on part of the sales floor in the event of an emergency. The goal is to make the store a trusted presence for the local community both during normal times and in times of crisis. The Matsudo store serves as an advanced example of GX (Green Transformation) at a store, contributing to the community and to decarbonization goals.
