ʻO ka hana mana o ka lā ma Iapana i ka makahiki 2030, e hāʻawi anei nā lā lā i ka hapa nui o ka uila o ke ao?

Ma Malaki 30, 2022, ua hōʻike ka Pūnaehana Comprehensive Pūnaehana, e noiʻi ana i ka hoʻokomo ʻana i nā ʻōnaehana photovoltaic power generation (PV) ma Iapana, i ka waiwai maoli a me ka manaʻo i manaʻo ʻia o ka hoʻomaka ʻana o ka ʻōnaehana photovoltaic e 2020.

Wahi a kāna mau manaʻo, ʻo ka hoʻokomo kumulative o nā ʻōnaehana photovoltaic ma Iapana e 2020 e pili ana i 72GW, e pili ana i ka puka pololei o kēia manawa (DC). Ma ka "kahi ulu o kēia manawa" e mālama i ka helu o kēia manawa o ka hoʻokomo ʻana o DC ma kahi o 8 GW i kēlā me kēia makahiki, ʻo ka wānana he 154 GW, me kahi hoʻopuka o kēia manawa (AC) (AC) o 121 GW ma FY2030Note 1). Ma ka ʻaoʻao ʻē aʻe, ʻo ka "Introduction Acceleration Case", i manaʻo ʻia e hoʻomaikaʻi maikaʻi a holomua i ke kaiapuni lawe mai, he kumu DC o 180GW (AC base o 140GW).

Ma ke ala, ma ka "Sixth Basic Energy Plan" i hoʻokumu ʻia e ka Ministry of Economy, Trade and Industry ma ʻOkakopa 22, 2021, ʻo ka nui o ka mana o ka lā i hoʻokomo ʻia ma Iapana i 2030 "117.6GW (AC ma kahi pae ambitious). Base )". ʻO ka pae "ambisious" o ke Kuhina Waiwai, Kālepa a me ʻOihana ua aneane like me ka wikiwiki o nā hoʻolauna.

Eia naʻe, helu ʻia kēia mau waiwai hoʻopuka ʻōnaehana PV e pili ana i ka DC ke hoʻokō ʻia kekahi mau kūlana e like me ka mahana a me ka kihi o ka lā. ʻO ka ʻoiaʻiʻo, ʻo 7 mau manawa (×0.7) ke kiʻekiʻe o ka hana mana ʻupena. ʻO ia hoʻi, ma ka 2030, manaʻo ʻia e hiki ke hoʻohua ma kahi o 85 GW ma lalo o ke kūlana ulu o kēia manawa ma kahi o ke awakea i ka wā lā i ka lā, a ma kahi o 98 GW ma lalo o ka hoʻolauna wikiwiki (ʻelua AC-based ).

Ma ka ʻaoʻao ʻē aʻe, ʻo ka koi nui o ka mana makahiki o Iapana ma kahi o 160GW (ma kahi kumu hoʻololi i kēia manawa). Ma mua o ka Great East Japan ōlaʻi i loko o Malaki 2011, ia mea ma kahi o 180GW (e like me luna), akā, me ka holomua o ka nohona ikehu-ho'ōla kaʻina hana, i ka hoʻokele waiwai ulu ana ua lohi iho, a me ka hoʻokele waiwai hoʻololi 'ia ua holomua, a me ka mana hana ua hoole. Inā ʻaneʻane like ka koi uila i ka makahiki 2030 me ia i kēia manawa, hiki ke helu ʻia ʻo 98GW / 160GW = 61% a ʻoi aku paha o ke koi uila holoʻokoʻa o Iapana e hiki ke hoʻokō ʻia e ka mana o ka lā i ka lā a me ka lā.
