When we began selling photovoltaic systems at stores in 2008, we launched initiatives for installing the systems in stores as well. As part of promoting sales to visiting customers, generated electricity is used to power in-store lighting.

Effect of photovoltaic power generation [Power generation only]

22.24t-CO2/year

※Total CO2 emission reduction of 6 business sites

  • As actual annual amounts of electricity generated are unavailable for Kishiwada Store and Nagaokakyo Store, the total amount of six stores is calculated based on planned annual amounts of electricity generated.
  • As actual annual amounts of electricity generated are unavailable for Kishiwada Store and Nagaokakyo Store, the total CO2 emission reduction of six business sites is calculated based on planned annual amounts of electricity generated.
  • What percentage of electricity consumed by in-store lighting is covered by photovoltaic power generation? (Average electricity generated per day ÷ electricity consumed by in-store lighting per day.)

* Calculated with METI’s CO2 emission coefficient of 0.000429t-Co2/kWh
** The figures for stores with power generation only have not been updated and have remained unchanged since FY2014.
