[Case Study] Tenhou Foods Co., Ltd.

[Case Study] Tenhou Foods Co., Ltd.

Utilized the roof that was not being used! Achieved heat insulation effects, reducing the store's utility costs.

We would like to introduce a case study of the solar power roof leasing business implemented by Tenhou Foods Co., Ltd. In recent years, many disasters have occurred around the world due to the effects of global warming. The Great East Japan Earthquake that occurred in 2011 and the Fukushima Daiichi Nuclear Power Plant accident have caused many people to continue to struggle due to the leakage of radioactive materials. In order to provide safe and secure meals, the company has been voluntarily conducting regular radiation inspections and measurements of the ingredients and products used. To ensure that everyone can enjoy delicious gyoza and ramen made with even safer ingredients, we decided to implement solar power generation, hoping that natural energy will become more widespread. [Case Study] - Implementation Date: May 2018 - Implementation Locations: Azumino City, Nagano Prefecture; Okaya City, Nagano Prefecture *For more detailed information about the case study, please visit our company website. Feel free to contact us for more details.

[Aozora Electric Power PPA Implementation Case] No maintenance costs and no repair cost risks!

[Aozora Electric Power PPA Implementation Case] No maintenance costs and no repair cost risks!

Thanks to self-consumption, Flair Original Co., Ltd. is able to feel the reduction in electricity costs.

We would like to introduce a case study of the introduction of Aozora Electric's PPA solar power generation at Flair Original Co., Ltd. Initially, we proposed both the roof leasing business and the Aozora Electric business. After calculating the profits, both businesses were profitable, so they were uncertain. However, since they were going to introduce solar power, they decided to consume it themselves and chose the Aozora Electric business. 【Case Study】 ■Implementation Date: February 2020 ■Location: Sakaki Town, Nagano Prefecture *For more details on the case study, please visit our website.

[PPA Model Implementation Case] The deciding factors are the speed to start power generation and the track record!

[PPA Model Implementation Case] The deciding factors are the speed to start power generation and the track record!

The results after 5 months of operation at Nitto Denko Kanto Office are 141,578 kWh generated! A reduction of 70.0 t-CO2/kWh in CO2 emissions has been achieved.

This is a case study of Nitto Denko Corporation, which operates globally in sectors such as electronics, automotive, life sciences, and environmental-related fields. The company learned about Aozora Electric Power while considering solar power as a method for acquiring renewable energy. Since it takes time from budget planning to the start of power generation for in-house implementation, they decided to choose Aozora Electric Power (PPA model), which does not require initial investment or maintenance costs. 【Installation System Overview】 ■ Panel Installation Location: Factory Roof ■ Power Generation Output (Module): 382.20 kW ■ Power Generation Output (Power Conditioner): 250.00 kW ■ Installation Area: Approximately 1,975 m² ■ Management Equipment: Remote Monitoring System for Power Generation ■ Orientation (0 degrees being true south): 0 degrees east ■ Incline: 2 degrees (following the roof) *For more details, please refer to the PDF document or feel free to contact us.

[Countermeasures for Rising Electricity Costs] Solved with Self-Consumption Solar Power Generation!

[Countermeasures for Rising Electricity Costs] Solved with Self-Consumption Solar Power Generation!

We will introduce self-consumption solar power generation, including the highly economical "self-investment model" and the "PPA model," which allows for the introduction of equipment without cost burden.

◆Self-Investment Model This model allows customers to purchase their own solar power generation system. Since the electricity generated can be used for free, the cost-effectiveness is maximized. - The reduction in running costs is maximized as the generated electricity can be used for free. - It allows for the utilization of the value of reduced environmental impact. - It is eligible for various preferential measures such as special depreciation and exemptions from property taxes. ◆PPA Model This is a method of installation that provides a self-consumption solar power generation system at no cost. By lending the facility's roof to the power plant owner for free, there are no costs associated with maintenance, removal, or equipment, allowing for the use of clean electricity. - The only cost incurred is for the electricity used, with no basic fee. - There are no installation or maintenance costs. - You can use 100% clean electricity generated from the roof. - Monitoring information can be visualized and used for facility PR. - If you feel the benefits are significant, purchasing the equipment midway is also possible. Implementing a self-consumption solar power generation system requires various specialized considerations, such as securing generation capacity and matching it with consumption levels. We apologize, but there may be facilities where installation is not recommended. Please contact us first regarding the feasibility of installation.
