據路透社4月19日消息，日本工業部一名官員周五表示，日本正考慮將其區域間電網容量從目前的約24吉瓦增加一倍，以幫助加快海上風力發電場等可再生能源的擴張。

　　此舉正值日本加快發展清潔能源，以幫助該國到2050年實現碳中和的目標，同時電網的薄弱一直是日本發展可再生能源的障礙。

　　這位官員表示，工業部和輸電運營商跨地區協調組織(OCCTO)正在考慮一項計劃，即修建海底電纜，連接北海道北部島嶼和電力需求旺盛的本州島。

　　他指出，其他可能的計劃包括加強北部東北地區和本州島東京都市圈之間的傳輸線路，以及加強南部九州島和本州島之間的電網。

　　《日經新聞》周四報道稱，日本工業部和OCCTO已共同制定一份計劃草案，擬將區域間電網容量翻倍。

　　這位官員表示:“我們仍在考慮這些計劃，尚未敲定。”他補充稱，中期報告可能會在5月份編制，而實際計劃將在下一個財年敲定，在2023年或之后開工。

　　Japan considers doubling inter-regional power grid to boost renewable energy

　　Japan is considering doubling its inter-regional power grid capacity from around 24 gigawatts now to help speed up expansion of renewable energy such as offshore wind farms, an industry ministry official said on Friday.

　　The move comes as Japan gears up its drive to expand cleaner energy to help the country achieve its goal of becoming carbon neutral by 2050, and as the weak power grid has been a hindrance to the growth of renewable energy in Japan.

　　The industry ministry and the Organization for Cross-Regional Coordination of Transmission Operators (OCCTO) are considering a plan to build undersea cables to connect the northern island of Hokkaido and the main Honshu island where power demand is high, the official said.

　　Other potential plans include boosting transmission landlines between the northern Tohoku region and the Tokyo metropolitan areas on Honshu island, and reinforcing grids between the southern island of Kyushu and Honshu, he said.

　　The Nikkei business daily reported on Thursday that the industry ministry and the OCCTO have put together a draft plan to double the inter-regional power grid capacity.

　　"We are still considering those plans and nothing have been finalised," the ministry official said, adding that an interim report will likely be compiled in May and the actual plan will be finalised next fiscal year, with construction starting in or after 2023, he said.
