Forecast: Total Electricity Generation in Japan

In 2023, Japan's total electricity generation stood at 986.25 thousand gigawatt-hours. Moving into 2024, the forecast indicates a slight decline to 982.87 thousand gigawatt-hours, marking a year-on-year decrease of approximately 0.34%. The downward trend is expected to continue through 2025 and beyond, with forecasts showing a decrease to 979.55 thousand gigawatt-hours in 2025 and further declines to 976.3 thousand gigawatt-hours in 2026 and 973.11 thousand gigawatt-hours in 2027. This reflects an average annual decline (CAGR) of about 0.34% over the five-year period.

Future trends to watch for include the potential impact of Japan's energy transition policies aimed at increasing the share of renewable energy, advancements in energy efficiency, and the possible decommissioning of older, less efficient power plants. Additionally, changes in industrial activity and technological innovations could further influence electricity generation levels.
