Miyawaka Storage Power Plant Completes Testing for Demand-Supply Market Entry

Miyawaka Storage Power Plant Completes Testing

The Miyawaka Storage Power Plant, developed by Sustainable Holdings Co., Ltd., headquartered in Shibuya, Tokyo, has completed its testing involving aggregator operations. This marks a significant milestone as the plant prepares to enter the demand-supply adjustment market scheduled for November 2026.

Overview of Miyawaka Storage Power Plant

The Miyawaka Storage Power Plant, which was completed in July 2026, is a grid-connected battery storage system designed to charge and discharge based on the power supply and demand status. The introduction of grid-connected battery systems necessitates careful planning around site conditions, grid connection environments, and equipment specifications. Sustainable Holdings oversaw all aspects of this project from equipment selection to installation.

Role of Utility-Scale Battery Systems in Demand-Supply Adjustment

In order to ensure a stable power supply, it is crucial to maintain a balance between the power generated and consumed. The demand-supply adjustment market serves as a platform for trading necessary adjustments required to uphold this balance. Utility-scale batteries play a critical role by charging during surplus energy periods and discharging during high demand times, thereby regulating the differences between supply and demand.

With renewable energy sources like solar power exhibiting fluctuations due to weather and time of day, utility-scale batteries are essential for stabilizing the power grid. This technology is increasingly seen as vital for responding to such variations in energy production.

Future Directions for Sustainable Holdings

Sustainable Holdings is dedicated to the selection and installation of battery systems tailored to the unique site conditions and grid connection environments of different regions. At the Miyawaka Plant, the company has worked closely with various stakeholders throughout the stages of equipment selection, installation, and preparations for market entry.

The knowledge gained from this project will be leveraged to enhance future utility-scale battery selection and installation endeavors.
