TOKYO, Jul 02 (Pulse News Wire) – Birdman Inc. (7063.T) announced that the construction and grid connection of its utility-scale battery storage system located at Tottori, Sakaiminato Shi Shozai was completed on October 27, 2025, ahead of the previously scheduled April 2026 timeline due to global transformer shortages and increased demand for high-voltage receiving equipment (cubicle).
The system began operations on July 04, 2026. The battery facility, with AC capacity of 1999.9 kW and DC capacity of 8,128 kWh, includes four units of HUAWEI's Luna2000-2.0MWH-2H1 batteries totaling 2,032 kWh and 24 units of power conditioners, also from HUAWEI, totaling 100 kW. It is designed to store excess renewable energy during peak daytime production and discharge it during evening peak demand periods, participating in the supply-demand adjustment market. Due to delays in cubicle delivery, the operational commencement was pushed back by approximately three months.
Despite this setback, the initial plan remains intact without changes to specifications or capacity. Following a trial operation phase lasting about three months, the system will transition to primary frequency regulation services within the supply-demand adjustment market, aiming to enhance asset utilization rates and stabilize revenue streams. In anticipation of the system’s contribution to fiscal 2027 sales, Birdman conservatively estimates around 280 million based on conservative assumptions considering regulatory limits in the supply-demand adjustment market. The company plans to continue evaluating potential acquisition of a second battery system post-trial operation.
Any significant developments related to future performance forecasts or progress on the second acquisition will be disclosed promptly.
