会社概要Company profile Under the vision of "Harmonizing New Energy and Power Systems," we are working toward a society where disaster-resilient, economical, and decarbonized energy can be used, by controlling new energy equipment such as EVs, storage batteries, and renewable energy generation facilities.
Among these efforts, we build and operate Virtual Power Plants (VPP), which use IoT/AI technology to remotely control thousands to tens of thousands of distributed energy devices so that they behave as a single power plant, and we aim to reach revenue of 10 billion yen by 2030.
Through Ministry of Economy, Trade and Industry demonstration projects adopted for 5 consecutive years, among others, we have built and operated advanced systems. In May 2023, we realized a VPP service through collaboration with the largest home storage battery manufacturer in Japan, and it was adopted by Tokyo Gas. In December 2023, we began joint demonstration with 8 major energy companies and aim for early commercialization.

What we value
We aim for an autonomous, decentralized society rather than a centralized social system, in order to "bring the blue Earth into the future" and "build a world powered 100% by renewable energy together," which are our purpose.
Therefore, we have established a system in which employees, while maintaining a professional spirit, can work autonomously with full flex and remote work available (depending on job content), and side jobs are also permitted.
To practice "enjoying nature," one of the company's Values (code of conduct), some employees have relocated to areas rich in nature and work there.
Also, to achieve an autonomous, decentralized society on a global scale, a mindset that accepts diversity is important. In fact, in our group, members from a wide variety of countries who share the same purpose work together, and official internal communication is conducted in both Japanese and English.
Our organizational culture is also very casual and flat.
For those who empathize with our purpose, we believe the environment is in place for them to work with a sense of conviction.
