[Case Study] Toa Corporation

[Case Study] Toa Corporation

Expecting insulation effects! A case where the factory felt cool during summer and the heat insulation effect was experienced.

We would like to introduce a case study of the solar power roof leasing business implemented by Toa Corporation. The company previously considered introducing solar power, but at that time it was expensive, so they focused on capital investment in their core business. They wanted to achieve some heat insulation effect in the factory during the summer and decided to implement the system with the hope that it would help mitigate the heat for factory workers. Additionally, the roof leasing business incurs no costs, provides stable rental income for 20 years, has high business viability, and contributes to the spread of renewable energy. 【Case Study】 - Implementation Date: July 2020 - Location: Nagano City, Nagano Prefecture *For more detailed information about the case, please visit our company website.

[PPA Solar Power Introduction Case] Improved demand values with peak cutting!

[PPA Solar Power Introduction Case] Improved demand values with peak cutting!

We felt that Shin-Etsu Food Industry Co., Ltd. is contributing to the community and the environment through CO2 reduction and local production and consumption of electricity.

We would like to introduce a case study of Shin-Etsu Food Industry Co., Ltd. implementing a solar power PPA with Aozora Electric. The company decided to install demand devices and began to consider reducing electricity costs. They made efforts such as introducing energy-efficient refrigerators and turning the power on and off according to electricity peaks, but felt they had reached their limits when they saw an article about Aozora Electric in a newspaper advertisement. With Aozora Electric, they could reduce purchased electricity by consuming the electricity generated themselves, and also improve demand values through peak cutting. They decided to implement it, believing that Aozora Electric was the only option to lower their demand peak. [Case Study] - Implementation Date: July 2019 - Location: Nagano City, Nagano Prefecture *Detailed information about the case study can be viewed on our company website.
