Our Services

We aim to promote more effective and immediate business development by aligning with the direction of renewable energy expansion, carbon neutrality, and market conditions. We also strive to create unique new value with an awareness of future social infrastructure development and contributions to local communities.

We develop and operate our own power plants

We have been developing and operating solar power plants at multiple locations in Japan, beginning with the Fukushima Solar Power Plant (panel output: 2,172 kW), which started operation in November 2014.
We also provide support for overseas expansion

Electricity Generation Implementing the UDA Model

We implement projects based on the User-Driven Alliance (UDA) model. This model advances the introduction of renewable energy based on commitments from consumers who need renewable energy, including through long-term purchase agreements or investments. It also includes bilateral transactions through on-site PPAs and FIPs.

Property Management Business

We continue to strengthen our management capabilities and develop systems that go beyond basic maintenance to help increase asset value. By implementing integrated management across multiple assets, we aim to ensure stable operations and consistent income to improve asset efficiency.

Battery Energy Storage System (BESS) Business

We engage in the development and operation of grid-connected battery storage facilities. Through this work, we address key social challenges such as stabilizing electricity market prices and consumer costs, reducing curtailment of renewable energy output, and supporting energy self-sufficiency and infrastructure development in remote areas and isolated islands.

Energy Resource Aggregation Business

As small-scale distributed energy sources—including solar, biomass, hydroelectric power, storage batteries, and electric vehicles (EVs)—continue to grow within regional power grids, we examine and promote models that integrate and control these resources using IoT and other technologies. These models enable autonomous energy operation within target areas, including disaster-related outage response, and support the creation and management of new energy platforms.
