Scheme Developed for Maximizing Use of Renewable Energy with Solar Power PPA
Model by SENKO, F-Bit Communications and Nihon Unisys- Aiming to increase the renewable energy ratio for achieving a carbon-free society, and effective utilization ofexcess solar power for power retailing
SENKO Co., Ltd. (Head office: Kita-ku, Osaka; President and Representative Director: Yasuhisa Fukuda), F-Bit
Communications Corp. (Head office: Minami-ku, Kyoto; Representative Director: Yukio Yoshimoto) and Nihon
Unisys Ltd. (Head office: Koto-ku, Tokyo; Representative Director: Akiyoshi Hiraoka) have developed the PPA
service* aimed at increasing the ratio of on-site consumption of the large-scale solar power generation systeminstalled at SENKO's large Gifu Hashima PD center, and created a scheme for the effective utilization of excess
power as a source for power retailing. The three companies are harnessing their respective expertise with the aimof achieving a low-carbon or carbon-free society and increasing the ratio of renewable energy.
* PPA services: Owners of facilities provide some area on the roof and other space free of charge, and companies operating
and managing power generation equipment (PPA operator) install the equipment there and at provide power generated there
for a fee to the owners of the facilities.

SENKO Group is aiming to become an "environmentally advanced corporation," and as such has used Green
Bonds for the construction of solar power generation systems (1,051 kW) on the entire roof of its Gifu Hashima PD
center as part of this scheme. Under ordinary circumstances involving on-site power consumption, the size ofpower generation equipment needs to be considered so that there is no excess power generated, whereas thisscheme allows the installation space to be used effectively so that generated power can be utilized on-site to themaximum extent possible. This approach will allow SENKO to achieve carbon-free processes throughout the entire
supply chain and increase its on-site consumption of renewable energy, while also supplying power retailer F-Bit
Communications with excess power to be utilized as a source of retail power, with the aim of securing a supply andpromoting greater use of renewable energy. Nihon Unisys will provide the systems for predicting the amount ofexcess power and the measured amount of power generation used for PPA model price calculations, to minimizing
the risk of imbalances (difference between planned and actual power generation) when using excess power as asource of retail power.
Methods for utilizing the various types of environmental value created with solar power generation will also be
examined to be applied as new initiatives aimed at achieving a low-carbon or carbon-free society and limiting globalwarming.
The solar power generation system used for this scheme is a system developed by Kyocera Corporation.
1. Overview of this Project
Name: PPA service for increasing on-site power consumption of renewable energy, and scheme developed for
effective utilization of excess power for power retailing
Project Commencement: Scheduled in 2021
Location: SENKO Gifu Hashima PD Center
Project details:<PPA service for increasing on-site power consumption of renewable energy>(1) Examine ways of increasing the ratio of on-site power consumption of renewable energy(2) Investigate ways to apply the scheme to other sites<Effective utilization of excess power for power retailing>(3) Increase the ratio of renewable energy and reduce procurement costs by utilizing excess power for power
retailing(4) Minimize risks of imbalances in the amount of predicted excess power and examine cost benefits(5) Examine ways of utilizing the environmental value
2. Role of each company
SENKO: Provide project site, examine the effects of increasing the ratio of on-site power consumption of renewableenergyF-Bit Communications: Provide data on amount of power, apply predicted results to supply and demand plan,assess profitability including excess power retailing and risks of imbalances, study environmental value utilization
business
Nihon Unisys: provide systems for predicting amount of excess solar power generation and measured amount ofpower generation used for solar power generation PPA model price calculations, support proposed simulations forproviding PPA models, study environmental value utilization business
3. Future plans
The range of know-how attained through this project will be utilized as part of plans for expanding the project toother logistics sites.
More studies are also planned to be conducted for further increasing the ratio of renewable energy at logistics sites
where electric vehicles are planned to used and charged with renewable energy.
Efforts will continue being made for developing a sustainable society and achieving zero emissions withinitiatives such as increasing the ratio of renewable energy power sources to power retailers, providing RE100*
options, and promoting greater use of distributed power sources like battery storage systems and electric vehicles
to PPA operators.
* A global initiative aimed at having companies use renewable energy to covering all the power used for their business
operations.
