日本经济产业省 (METI) 的最新数据显示，过去 12 个月，风电和太阳能弃电量大幅增加至 1.76 太瓦时，而 2022 财年为 0.57 太瓦时，2023 财年为 0.53 太瓦时。

New figures from Japan’s Ministry of Economy, Trade and Industry (METI) show that wind and solar power curtailment increased significantly to 1.76 TWh over the past 12 months, from 0.57 TWh in fiscal 2022 and 0.53 TWh in fiscal 2023.

2023财年（从2023年4月到2024年3月），日本的可再生能源限电量猛增 。

Renewable energy curtailment soared inJapanin fiscal 2023, which spans from April 2023 to March 2024.

日本可再生能源研究所根据经济产业省提供的数据称，太阳能和风能弃电量从 2018 财年的约 0.10 太瓦时增长到上一财年的约 1.76 太瓦时。

According to Japan's Renewable Energy Institute, which relies on data provided by METI, solar and wind energy curtailment grew from approximately 0.10 TWh in fiscal 2018 to around 1.76 TWh in the last fiscal year.

该研究所表示：“这个价值是澳大利亚和加利福尼亚州的两倍多。”

“This value is more than double those in Australia and California,” the research institute said.

2022 财年和 2021 财年可再生能源限电量分别达到 0.57 太瓦时和 0.53 太瓦时。此前两年，限电量分别达到 0.40 太瓦时和 0.46 太瓦时。

Renewable energy curtailment reached 0.57 TWh in fiscal 2022 and 0.53 TWh in fiscal 2021. In the preceding two years, curtailment hit 0.40 TWh and 0.46 TWh.

可再生能源研究所表示：“2021 财年之前，限电仅限于九州地区。” “除东京外，限电现在正在影响该国所有电力系统。九州的情况尤其成问题，预计 2023 财年太阳能和风电的弃风率将达到近 7%。”

“Until fiscal year 2021 curtailment was limited to Kyushu,” said the Renewable Energy Institute. “Except for Tokyo, curtailment is now affecting all the power systems of the country. The situation has become particularly problematic in Kyushu where the curtailment rate of solar and wind power was projected to reach nearly 7% in fiscal year 2023.”

该研究所表示，容量不超过10千瓦的光伏系统不会受到限电的影响，并指出“限电本质上是太阳能限电”。它补充说，光伏发电集中在白天和春季，“此时太阳辐照条件良好，用电量最低。”

The institute said that PV systems with a capacity of up to 10 kW are not exposed to curtailment and noted that “curtailment is essentially solar curtailment.” It added that power generation from PV sources is concentrated during the daytime and in spring, “when solar irradiance conditions are good and electricity consumption is the lowest.”

该研究所建议将经济调度和负电价作为未来几年减少限电的解药。

The institute suggested economic dispatch and negative prices as an antidote to reduce curtailment in the coming years.

根据国际可再生能源机构（IRENA）的数据，截至2023年底，日本累计光伏装机容量达到87.0吉瓦。去年，该国新增太阳能装机容量约为4吉瓦。

According to the International Renewable Energy Agency (IRENA), Japan reached a cumulative installed PV capacity of 87.0 GW at the end of 2023. Last year, the country deployed around 4 GW of new solar capacity.
