We will introduce examples of electricity cost reductions for stores using our "Corporate Electricity Plan" for restaurants, apparel shops, and membership clubs. Electricity usage tends to increase in the morning when stores begin preparations for opening, peak during the day, and decrease at night. Throughout the year, electricity consumption rises in the summer when air conditioning usage increases. We recommend the "Market-Linked Plan" and "Capped Market-Linked Plan," which offer lower daytime electricity costs, as well as the "Mix Plan," which reduces electricity costs in summer and winter. 【Case Summary (Partial)】 ■ Shikoku Number of locations: 2 Approximately 67 million yen/year → Approximately 37 million yen/year 45% DOWN ■ Shikoku Number of locations: 1 Approximately 6.6 million yen/year → Approximately 3.8 million yen/year 42% DOWN ■ Hokkaido Number of locations: 3 Approximately 7.3 million yen/year → Approximately 4.75 million yen/year 35% DOWN ■ Tokyo Number of locations: 1 Approximately 6.2 million yen/year → Approximately 4.15 million yen/year 33% DOWN *For more details, please download the PDF or feel free to contact us.

We would like to introduce examples of electricity cost reductions for offices using our "Corporate Electricity Plan." Offices tend to have many holidays on weekends, leading to a higher electricity usage during weekdays, especially during the daytime.

Our company can propose suitable plans tailored to the size of the office and the preferences of the corporation. 【Case Summary (Partial)】 ■ Hokuriku Number of locations: 1 Annual cost: approximately 2.6 million yen → approximately 1.5 million yen 43% DOWN ■ Tokyo Number of locations: 1 Annual cost: approximately 2.5 million yen → approximately 1.5 million yen 41% DOWN ■ Kyushu Number of locations: 2 Annual cost: approximately 5.9 million yen → approximately 3.5 million yen 40% DOWN ■ Kansai Number of locations: 1 Annual cost: approximately 47.65 million yen → approximately 32.22 million yen 32% DOWN *For more details, please download the PDF or feel free to contact us.

We would like to introduce examples of electricity cost reduction for hotels and accommodation facilities through our "Corporate Power Plan." Hotels and accommodation facilities tend to have high electricity usage throughout the day, regardless of weekdays or weekends, with increased power consumption during the summer and winter when air conditioning usage rises. We offer many options, including "fixed rate plans" and "fuel adjustment link plans" that can lower the daily electricity cost per unit, as well as "mix plans" that reduce electricity costs in summer and winter.

We would like to introduce a case study of electricity cost reduction for hospitals through our "Corporate Electricity Plan." Hospitals have high electricity usage throughout the day, regardless of weekdays or weekends, with a tendency for increased usage in the morning when patient consultations rise. Annually, electricity costs are higher in winter due to increased operation of heating equipment. We propose various plans such as the "Fixed Price Type" and "Fuel Adjustment Link Type" to lower the daily electricity cost per unit, as well as the "Mix Plan" which reduces electricity costs in both summer and winter.

We would like to introduce examples of electricity cost reduction for factories (operating year-round/operating on weekdays) through our "Corporate Power Plan." Factories that operate year-round use a large amount of electricity 24 hours a day, 365 days a year, and particularly in summer, the use of air conditioning tends to increase, leading to higher electricity costs. In factories that operate on weekdays, electricity usage increases from morning to night on weekdays. We recommend the "Market-Linked Plan," which offers lower electricity costs during the day, the "Fuel Adjustment Link Plan," which can reduce the unit price of electricity per day, and the "Fully Fixed Plan," which guarantees a reduction in electricity costs. 【Case Summary (Partial)】 ■ Year-round operation in China Number of locations: 3 Annual cost: approximately 32 million yen → approximately 18.6 million yen 42% DOWN ■ Year-round operation in Hokuriku Number of locations: 2 Annual cost: approximately 96.85 million yen → approximately 65.2 million yen 33% DOWN ■ Weekday operation in Tohoku Number of locations: 10 Annual cost: approximately 244.9 million yen → approximately 160.6 million yen 34% DOWN ■ Weekday operation in Hokuriku Number of locations: 2 Annual cost: approximately 50.05 million yen → approximately 32.9 million yen 34% DOWN *For more details, please download the PDF or feel free to contact us.
