Enhancing Energy Systems: The Introduction of Primary Control in TAMERBA EMS

In an exciting development for the energy sector, Power X Co., Ltd. and Nishimu Electronics Co., Ltd. have successfully added primary control capabilities to their joint product, TAMERBA EMS. This enhancement promises to improve energy supply stability across various markets, particularly during times of fluctuation in electrical demand and renewable energy outputs.

Aiming for Efficiency in Energy Management

Founded in March 2021 and led by CEO Masahiro Ito, Power X is located in Akasaka, Tokyo. It specializes in advanced energy systems. Nishimu Electronics, part of the Kyuden Group since 1963 and headed by President Hideyuki Yamashina, has been pivotal in developing technologies that cater to the needs of modern electrical grids, primarily based in Fukuoka.

These companies collaborated on the TAMERBA EMS as part of their High Voltage Package for Energy Storage Systems, which has recently been implemented at the Mitsuminegawa Ina Energy Storage Plant operated by Marubeni Corporation. This plant, located in Chiyoda, Tokyo, is set to commence operations in June 2025.

Role of Primary Control Capacity

The primary control capacity added to TAMERBA EMS allows for quick reactions to minute frequency fluctuations caused by variations in electrical demand or renewable energy generation. This is particularly critical in a market where maintaining a consistent system frequency is essential.

Nishimu Electronics has contributed its expertise by developing end-control features that enable autonomous discharging and charging in response to these frequency changes. In parallel, Power X has been responsible for the development of essential hardware like Mega Power storage systems and power conditioning systems (PCS), all of which have undergone rigorous performance testing in collaboration with regional transmission operators before this new functionality was approved for real-world application.

Potential for Market Integration

The upgrade of the TAMERBA EMS is poised to enhance the operational capabilities of energy storage facilities utilizing this package. By integrating primary control with wholesale electricity trading and capacity markets, facilities can now operate more effectively, reflecting the ever-evolving dynamics of the energy market.

The future looks promising for both Power X and Nishimu Electronics, as they continue advocating for the effective utilization of renewable energy resources across society. Their commitment to expanding the deployment of the High Voltage Package for Energy Storage Systems, which consists of Mega Power and TAMERBA EMS, is a significant step towards achieving greater energy sustainability.



With this collaborative effort, both companies are set to lead the way in modernizing our energy infrastructure, emphasizing the importance of innovative technology in managing the growing complexity of energy demand. As they pave the way for future advancements, stakeholders can expect significant improvements in the reliability and efficiency of our energy systems.
