'About Japan' webinar series 268: Battery Energy Storage Systems (BESS) in Japan - Market Structure, Business Models and Entry Opportunities for EU Companies

What concrete business opportunities does Japan’s fast-growing battery energy storage market offer to EU companies, and how can they realistically enter it?

Japan is accelerating the deployment of large-scale and distributed Battery Energy Storage Systems (BESS) to support renewable integration, grid stability, and energy security. Driven by ambitious decarbonisation targets, evolving electricity market reforms, and generous public support schemes, Japan is rapidly becoming one of the most attractive — yet complex — storage markets globally.

This webinar provides an overview of the Japanese BESS market, based on an in-depth market study. It explains how the market actually works, who the key actors are, how revenues are generated, and where EU companies can realistically position themselves — whether as technology providers, developers, investors, or service partners.

The webinar is targeted at EU companies and non-profit support organisations seeking to enter, expand, or support entry into Japan’s battery energy storage market, including technology suppliers, IPPs, investors, EPCs, integrators, and advisory bodies.
