PowerX Adopts Mega Power Storage in Kyushu Solar Plants

PowerX, headquartered in Okayama, Japan, has made a significant move in enhancing renewable energy resources in Kyushu. The company announced that it will utilize the "Mega Power" energy storage system in collaboration with Blue Sky Solar, which operates four solar power plants in the region.

Energy Storage Overview

The initiative will include the installation of a total of 11 energy storage units, boasting a cumulative storage capacity of 30.1 MWh, across these solar facilities. The storage solutions are developed in partnership with Nishimu Electronics, a company located in Fukuoka, Japan. The launch of operations for these systems is projected to commence in the spring of 2026.

Each solar plant will implement a packaged energy storage system that integrates seamlessly with solar power generation. Using an advanced Energy Management System called "TAMERBA EMS," the setup will harness solar energy generated during the day, storing it for later use. The stored energy will be discharged during peak demand times, such as evenings and nighttime, thereby improving efficiency and reliability in energy distribution.

Benefits to Energy Providers

This innovative setup offers a multitude of advantages to power producers. By employing the Mega Power system, they can mitigate the risks associated with output suppression, which often results in reduced revenue from power sales. Notably, this partnership enables a transition from the Feed-in Tariff (FIT) system to the Feed-in Premium (FIP) system for selling generated electricity. This shift is expected to enhance the economic viability of renewable energy projects.

Furthermore, the effective utilization of fluctuating renewable energy sources — largely influenced by weather conditions — will contribute significantly to a more sustainable society. This initiative not only increases the operational technicality of solar plants but also dovetails with Japan's broader commitment to sustainable energy.

Support From Local Government and Investment

The project has also garnered support from Japan's Resource Energy Agency through its "Renewable Energy Source Accompanied Energy Storage Support Project." Additionally, Mizuho Securities has taken a significant step by establishing a new fund aimed at large-scale energy storage implementations, indicating strong financial backing for this ambitious venture.

Installation Locations and Specifications

Each designated plant has specific storage capacities tailored to the local conditions:

• - Usa City, Oita Prefecture: 3 containers with a storage capacity of 8,226 kWh and a PCS output of 1,995 kW.
• - Isa City, Kagoshima Prefecture: 3 containers, identical capacity and output.
• - Kanoya City, Kagoshima Prefecture: 2 containers with 5,484 kWh capacity and 1,500 kW output.
• - Minamikyushu City, Kagoshima Prefecture: 3 containers with a capacity of 8,226 kWh and a PCS output of 1,750 kW.

With the anticipated operational start from March 2025 onwards, PowerX is determined to expand the reach of its energy storage packages, thereby promoting renewable energy proliferation and contributing to decarbonizing the electricity infrastructure in Japan.
