Polarium is proud to announce the successful completion of its first Battery Energy Storage System (BESS) installation in Japan. Polarium has commissioned a 1 MWh BESS at a prominent Agricultural Facility in Satsumasendai, Kagoshima, located in southern Japan, for Iwatec Corporation.

The BESS installation represents a fusion of innovation, comprising nine Polarium 115kWh High-Voltage (HV) indoor racks and solar PV arrays, all integrated into a unique microgrid system. This robust setup not only ensures reliable energy storage but also optimizes the utilization of renewable energy sources, thereby contributing to a more sustainable future for the region.

Through the use of solar systems and now Polarium’s BESS, Iwatec’s affiliate company, Iwatec Agriculture will commence production of premium customer-grade shiitake mushrooms in April, 2024. The factory serves as a model for sustainable farming practices, ensuring the consistent quality of its products but also contributing to the preservation of the local ecosystem – with potential applications in various industrial sectors.

“We at Iwatec are impressed with Polarium’s energy storage solutions, particularly the modularity and premium design they offer. With their continued support, we are excited to advocate for Polarium BESS within the Japanese Commercial and Industrial (C&I) market, both locally and abroad,” says Koichiro Iwamoto, President & CEO, Iwatec Corporation.

"Polarium is dedicated to effecting positive transformation in the energy sector, and this project marks a major advance toward that goal. Through collaboration with innovative partners like Iwatec, Polarium is focused on accelerating the adoption of clean energy technologies, contributing to the development of a more resilient and sustainable energy ecosystem in Japan and beyond." says Carl-Erik Lagercrantz, chairman of Polarium.

Iwatec Corporation, located in Nagasaki, Japan, is a green energy company offering diversified engineering services in geothermal, hydrogen, photovoltaic, fuel cell, biomass, and energy storage sectors, both in and outside Japan.
