Public Seminar Laying the Groundwork for Offshore WindBuilding the Grid and Designing the Market for the Renewable Era

19 June 2025

in Japanese

As Japan looks to scale up renewable energy, a major redesign of the country's electricity infrastructure is essential. Offshore wind in particular depends on a complete set of transmission lines—access lines, internal lines, and inter-regional connections—all requiring significant investment. This seminar looked at how grid development and smart market design can support large-scale renewable integration, with insights from both Japan and Northern Europe.
