SINEXCEL has announced that its first battery energy storage project to enter Japan’s frequency regulation market officially began market trading in June. Located in Matsusaka, Mie Prefecture, the 2MW/8MWh system marks a significant milestone in the company’s participation in Japan’s rapidly evolving energy storage market.
Japan’s frequency regulation market is known for its stringent technical and operational requirements for battery energy storage systems, including performance, response speed, reliability and system integration capabilities. Before entering commercial operation, the Matsusaka project successfully completed grid connection, system commissioning, market qualification and trading registration.
Delivered in collaboration with local partners, the project was developed to meet all applicable market requirements and support stable participation in frequency regulation services, demonstrating the readiness of SINEXCEL’s energy storage solutions for one of the world’s most demanding power markets.
The project incorporates two SINEXCEL 1375 kW PCS units within a 2 MW/8 MWh battery energy storage system. Designed to meet Japan’s stringent grid connection and power quality requirements, the PCS delivers fast response, precise power control and reliable grid support capabilities essential for frequency regulation services.
