日本:2023财年大幅消减太阳能和风能

2024-04-16 10:14来源:北极星太阳能光伏网 日本经济产业省(METI)的最新数据显示,在过去的12个月内,日本风能和太阳能削减量大幅提高,从2022财年的0.57TWh和2023财年的0.53TWh增至1.76TWh。 日本可再生能源研究所称,根据METI提供的数据显示,日本太阳能和风能削减量从2018财年大约0.10TWh增加到上一财年的1.76TWh左右,这一数值相当于澳大利亚和加利福尼亚的两倍多。 具体来看,2022财年可再生能源削减量达到0.57TWh,2021财年达到0.53TWh,且此前两年的削减量分别为0.40TWh和0.46TWh。 据可再生能源研究所透露:“在2021财年之前,削减范围仅限于九州。如今,削减影响着东京地区以外的所有电力系统。九州的情况尤为严重,预计该地区2023财年的太阳能和风能削减幅度将达到近7%。” 该研究所表示,容量在10kW及以下的光伏系统不会受到削减的影响,并指出“主要是削减太阳能”。该研究所还补充说,光伏发电集中在“太阳辐照度条件良好且耗电量最低”的日间和春季。 该研究所建议将经济调度和负电价作为降低未来几年内削减量的解决办法。 根据国际可再生能源机构(IRENA)的数据,截至2023年底,日本光伏累计装机量达到87GW。去年,该国新增约4GW的太阳能发电量。
