We would like to introduce a case study of Shin-Etsu Food Industry Co., Ltd. implementing Aozora Power's PPA solar power generation. 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 power on and off according to electricity peaks, but felt they had reached their limits when they saw an article about Aozora Power in a newspaper advertisement. With Aozora Power, they could reduce purchased electricity by consuming the electricity generated on-site, and also improve demand values through peak cutting. They decided to implement Aozora Power, believing it was the only solution to lower their demand peaks. 【Case Study】 ■Implementation Date: July 2019 ■Location: Nagano City, Nagano Prefecture *For more details about the case, please visit our company website.
