Hydropower supply Japan FY 2013-2022

The hydropower supply in Japan amounted to around 660 petajoules in fiscal year 2022, which was a slight decrease compared to 673 petajoules in the previous fiscal year. Since the country has constructed large-scale hydroelectric facilities at nearly all potential sites, typically at large dams, a further increase in the generation capacity is hardly possible.

在日本，2022财年水力发电的供应量约为660太焦耳，较上一年度的673太焦耳略有下降。鉴于该国已在几乎所有潜在的地点，尤其是大型水坝，建立了大规模的水电设施，进一步增加发电能力几乎成为不可能之事。
