iGrid Solutions Achieves Nationwide On-Site PPA Development

In a groundbreaking achievement, iGrid Solutions, based in Minato, Tokyo, has announced the successful implementation of its on-site Power Purchase Agreement (PPA) development across all 47 prefectures in Japan. This milestone has been marked by surpassing 1,500 installations, showcasing an innovative approach to renewable energy.

Innovating Renewable Energy Solutions

Since 2017, iGrid Solutions has focused on optimizing existing facilities, including retail stores, logistics centers, and manufacturing plants, to facilitate on-site PPAs. These agreements enable power suppliers to install solar energy systems on the roofs of client facilities, thus allowing them to utilize generated electricity on-site. This model reduces initial capital investment and maintenance burdens while contributing significantly to cost savings on energy and promoting decarbonization, making it increasingly attractive for companies nationwide.

A prime example of their work is the solar energy installation at the MaxValu Tomakomai Shimizu store in Hokkaido, set to launch in June 2026. This addition confirms iGrid's network of decentralized solar power stations now spans all regions in Japan. Adapting to local conditions, especially in terms of climate and building characteristics, is essential for the successful design, construction, and operation of these systems. Leveraging their extensive experience, iGrid aims to facilitate the introduction of renewable energy tailored to the specific needs of each region.

The access to renewable energy generation potential on the rooftops of various corporate facilities is a clear indication of the possibilities presented by iGrid’s initiatives, regardless of the local characteristics or industries involved. By broadening the scope of their installations, iGrid Solutions actively supports companies in achieving their decarbonization goals and aids in the proliferation of renewable energy in communities nationwide.

Utilizing Energy Efficiently with Over 1,500 Facilities

To effectively manage the expansive network of over 1,500 decentralized solar power stations across Japan, iGrid employs its proprietary AI platform, the "R.E.A.L. New Energy Platform®". This technology allows for the predictive management of both energy production and consumption, aiming for maximum utilization of generated renewable energy.

Traditional onsite PPAs frequently face challenges associated with surplus energy production that cannot be consumed on-site, often leading to inefficiencies. However, iGrid has established a comprehensive "surplus energy circulation scheme" that anticipates and manages excess power, enabling it to be supplied to other facilities or combined with battery storage systems—thereby optimizing renewable energy usage.

Going forward, iGrid Solutions will accelerate its contribution to enhancing the renewable energy self-sufficiency of corporate sites while supporting their decarbonization efforts through its growing decentralized solar power generation capabilities.

Special Site Launch

In recognition of reaching this significant milestone of covering all 47 prefectures, iGrid has launched a special website. This platform highlights the company’s efforts in expanding decentralized solar power and explains the importance of utilizing corporate rooftops for renewable energy generation.
