Sharing Energy Co., Ltd.



Transform the energy system through the creation of DERs


We believe that maximizing the use of distributed energy resources (DERs) throughout the community, including residential PV systems, will contribute to realize a sustainable society.

Share Denki has achieved the innovation of providing PV systems with no initial cost, which used to require a large initial investment, and has been supported by many users and partners.

Each energy resource, such as PV system and energy storage system, may be insignificant in the context of the entire power system. However, when these distributed energy resources are bundled together, we believe they can have a significant impact.

Our mission is to transform the energy system for the better through the creation of distributed energy resources and the provision of innovative products.

代表メッセージCEO message

Share Denki, which started with the idea of “making solar power generation more accessible,” has been supported by many customers as a service with “no initial cost” and “charge at a competitive price as much as you spend.”.

The third party ownership or PPA model, in which the customer does not “own” the PV system, but rather “uses” it, is now becoming more widespread, thanks in part to the support of local governments and the government. However, since this model was completely new that overturned common sense, we received a lot of concerns from users and partners.

Nevertheless, with a strong belief that “spreading this service will benefit customers and society,” all members of our team have continued to sincerely listen to such voices, and the number of contracts for Share Denki exceeded 1,000 nationwide.

Now, we are continuing to expand into a platform that accelerates not only solar power generation but also the local production and local consumption of renewable energy. In the future, we will continue to contribute to the world by transforming the energy system through the creation of distributed energy resources and realizing a sustainable society.
