ＪＥＲＡ、電力の卸価格つり上げ　相場操縦で改善勧告―取引監視委

　電力・ガス取引監視等委員会は１２日、東京電力グループと中部電力が折半出資する国内最大の発電会社ＪＥＲＡ（東京）に対し、卸電力市場で相場操縦を行ったとして業務改善を勧告した。卸市場に電力を供給する余力があったにもかかわらず、発電を行わなかったことで取引価格をつり上げたという。
　国の指針は大規模な発電事業者に対し、余剰電力のすべてを卸市場に供給するよう求めている。ただ、監視委によると、ＪＥＲＡは２０１９年４月から２３年１０月までの間、一部の余剰電力の供給を怠った。これにより、２１年１１月には取引価格を最大で１キロワット時当たり５０円以上つり上げた可能性がある。（2024/11/12-21:14）

The Electricity and Gas Market Surveillance Commission has told Jera Co., the largest power generation company in Japan, to improve its business operations for alleged market manipulation.
   Jera, a joint venture between the Tokyo Electric Power Company Holdings Inc. group and Chubu Electric Power Co., raised wholesale prices of electricity by reducing its output when it was actually able to provide electricity to the wholesale market, the commission under the industry ministry said Tuesday.
   Japanese regulations require large power generation companies to supply all surplus electricity to the market.
   According to the commission, Jera failed to provide part of its surplus electricity between April 2019 and October 2023. As a result, the transaction price per kilowatt-hour is believed to have been raised by 50 yen or over in November 2021.
   This is the second business improvement advisory issued by the commission due to market manipulation.
