[Report] Forecast of Solar Power Installation in Japan (2023-2035)

Forecasting the amount of solar power installation in Japan over the next 10 years from two scenarios: "current growth case" and "acceleration case."

The "Energy Supply Resilience Act" and the "Revised Global Warming Countermeasures Promotion Act" have been enacted, accelerating efforts in energy and environmental policies towards achieving a 46% reduction in greenhouse gases by 2030. The government has established a "Basic Policy for Realizing GX (Green Transformation)," clearly stating the goal of achieving a power generation ratio of 36-38% from renewable energy sources by 2030, which has now become a mandatory target, previously considered ambitious in the Basic Energy Plan. On the demand side, there is an increase in electricity demand due to the recovery from the COVID-19 pandemic, and the desire to introduce solar power has risen as a response to the soaring energy prices and electricity rates triggered by Russia's invasion of Ukraine. The use of renewable energy for SDGs and enhancing corporate value is expanding throughout the supply chains of major domestic companies. The introduction ratio is expected to increase with the shift from the FIT system to self-consumption models, PPA models, and the FIP system. This document looks ahead to the next decade, analyzing price forecasts, changes in social environments, market changes, and technological advancements from two scenarios: the "Current Growth Case," which aims to achieve the 2030 introduction target, and the "Acceleration Case," where the introduction environment significantly improves and progresses. It predicts the amount of solar power installation by application and scale.
