KDDI Corporation, au Energy Holdings Corporation, ENERES Corporation, and Lawson, Inc. will begin a demonstration experiment (hereinafter, this demonstration) in November 2025 to share power generated by solar power generation equipment and storage battery equipment installed at Lawson stores in Gunma Prefecture across 32 stores, with the aim of reducing CO2 emissions from Lawson stores and stabilizing the power supply-demand balance.
This initiative to install three types of solar power generation equipment-solar carports, vertical bifacial solar panels, and rooftop solar panels-along with storage battery equipment at stores and share power among multiple stores is the first of its kind in the Japanese convenience store industry.
In this demonstration, storage battery equipment will be installed at 26 Lawson stores in Gunma Prefecture, and solar power generation equipment such as solar carports and vertical bifacial solar panels will be installed at two of those stores. Including six stores where solar power generation equipment and storage battery equipment cannot be installed, we will verify optimal integrated control of power across a total of 32 stores. Utilizing ENERES’s power generation predicting technology and storage battery control technology, renewable energy power generated and stored at stores will be shared with other stores where installing solar power generation equipment is difficult.
Through this demonstration, we aim to reduce CO2 emissions from Lawson stores and stabilize the supply-demand balance of the entire power grid by providing adjustment capacity using storage batteries. In addition, in the event of a natural disaster, the initiative will contribute to regional resilience by utilizing storage batteries to maintain basic convenience store operational functions such as lighting and cash registers.
Based on the results of this demonstration, the four companies will consider increasing the number of stores equipped with solar power generation equipment and storage battery equipment.
