Started a demonstration experiment on store management of "100% renewable energy" utilizing electric vehicle batteries, high-performance solar panels, and electricity derived from "Graduate FIT"

SEVEN-ELEVEN JAPAN Co., Ltd. has started a demonstration experiment to procure all electric energy for store operations from renewable energy sources at 10 Seven-Eleven stores in Kanagawa Prefecture since September 26, 2019 (Thursday). This initiative based on the "Agreement on Cooperation and Collaboration for the Promotion of the SDGs" with Kanagawa Prefecture and the Seven & I Group's "Environmental Declaration." This is the first attempt at Seven-Eleven.

This initiative is an experiment to replace all electricity consumption for store operations with renewable energy sources that do not generate CO2 during power generation, resulting in a significant reduction of CO2 emissions.

Original storage batteries by 4R Energy using reused batteries from Nissan Motor's Nissan LEAF electric vehicle, and solar panels with greatly improved power generation efficiency by Kaneka were installed to efficiently utilize the power generated in-house.

In this scheme, stationary storage batteries were introduced using Nissan LEAF electric vehicles and used LEAF batteries. Nissan LEAF, which is introduced as a sales vehicle, will be transformed into a stationary storage battery after it is no longer used as a vehicle. This is a circulation system that takes into account the reuse of the batteries. As for the procurement of electricity other than that generated by the system, Smart Tech has supplied us with electricity derived from "Post-FIT*2" since November 2019. That enables us to achieve a substantive renewable energy ratio of 100%*2 together with our power generation.

*1: FIT is an abbreviation for Feed-in Tariff. The FIT system is a subsidy system that fixes the purchase price of produced energy. Since November 2019, the photovoltaic power generation has reached the end of the system in sequence.

*2: Combining the use of electricity generated and storage in stores and the use of electricity derived from "Post-FIT" can achieve a substantive renewable energy ratio of 100%.
