据路透社4月19日消息，日本工业部一名官员周五表示，日本正考虑将其区域间电网容量从目前的约24吉瓦增加一倍，以帮助加快海上风力发电场等可再生能源的扩张。
此举正值日本加快发展清洁能源，以帮助该国到2050年实现碳中和的目标，同时电网的薄弱一直是日本发展可再生能源的障碍。
这位官员表示，工业部和输电运营商跨地区协调组织(OCCTO)正在考虑一项计划，即修建海底电缆，连接北海道北部岛屿和电力需求旺盛的本州岛。
他指出，其他可能的计划包括加强北部东北地区和本州岛东京都市圈之间的传输线路，以及加强南部九州岛和本州岛之间的电网。
《日经新闻》周四报道称，日本工业部和OCCTO已共同制定一份计划草案，拟将区域间电网容量翻倍。
这位官员表示:“我们仍在考虑这些计划，尚未敲定。”他补充称，中期报告可能会在5月份编制，而实际计划将在下一个财年敲定，在2023年或之后开工。

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 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 The Nikkei business daily reported "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.
