[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.

[Measures Against Rising Electricity Costs] Solve it 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. - The value of reducing environmental impact can be utilized. - It is eligible for various preferential measures such as special depreciation and reductions in property tax. ◆PPA Model This is a method of installation that provides a self-consumption type 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 fees. - 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 promotion. - If you feel the benefits are significant, it is possible to purchase the equipment midway. Implementing a self-consumption type 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 inquire first about the feasibility of installation.
