Announcement of the Release of 'Key Points of Renewable Energy and Battery Storage Policies 2026: Solar Power Moving Toward Independence'

Resource Total System Inc. (headquartered in Chuo-ku, Tokyo; President: Osamu Ichiki, hereinafter referred to as 'the Company' or 'Resource Total System'), a firm specializing in research, analysis, and consulting services for solar power and related businesses, has released the report 'Key Points of Renewable Energy and Battery Storage Policies 2026' on July 13, 2026.

Global cumulative solar PV installations reached 3TW by the end of April 2026. In Japan, the maximum utilization of renewable energy is increasingly demanded, driven by economic growth as well as energy security and decarbonization goals. While solar power urgently requires market integration and measures for long-term stable operation to address challenges such as economic viability, grid constraints, and social acceptance, the battery storage sector is also experiencing rapid market formation, including the transition of existing FIT solar power plants to FIP with co-located battery storage, and the expansion of grid-scale battery systems.

This report outlines key policy points concerning solar power, including the mega-solar countermeasure package, solar power deployment in infrastructure spaces, residential solar power, perovskite solar cells, desirable agrivoltaic systems, and solar panel recycling systems. It also covers battery storage policies, such as ensuring grid connection discipline, new market mechanisms like long-term decarbonized power auctions, capacity markets, and balancing markets, as well as projected grid battery deployment. Additionally, it explains cybersecurity measures (JC-STAR program) relevant to both solar power and battery storage.

We encourage all stakeholders in the solar and battery storage industries to utilize this report to stay informed on the latest policy developments.
