Mitsubishi Research Institute, Inc. and Hitachi, Ltd. have signed a Memorandum of Understanding to develop a cooperative framework aimed at delivering advanced power-trading support services for grid-scale battery operators. The collaboration will integrate Mitsubishi's MERSOL service with Hitachi's Power Trading System, creating a unified Power Trading Service.
The service, set to launch in fiscal year 2027, aims to streamline operations by providing seamless support from automated bid planning to actual market transactions. This integration will allow operators to internalize sophisticated trading operations, which are often outsourced, thereby improving profitability and scalability.
As Japan accelerates its renewable energy expansion to meet carbon neutrality goals by 2050, grid-scale batteries play an essential role in balancing supply and demand. The new service will help battery businesses navigate multiple markets such as the Japan Electric Power Exchange and the Electric Power Reserve Exchange, enhancing their ability to conduct strategic trading in-house.
By automating complex trading workflows, the service is expected to reduce outsourcing costs, enable faster decision-making, and allow companies to accumulate valuable operational expertise. This will not only enhance profitability but also make it easier for operators to scale their business operations across multiple battery-storage sites.
Through this partnership, Mitsubishi and Hitachi aim to support the growth of grid-scale battery businesses, contributing to a sustainable and carbon-neutral society. The companies plan to offer their respective systems as standalone solutions, in addition to the integrated service, to further support the sector's expansion.
