過去１０年で最も厳しく　厳寒時、東電は「ぎりぎり」―冬の電力需給・経産省

　経済産業省は２６日の有識者会議で、今年度の冬の電力需給についての見通しを公表した。１０年に１度の厳しい寒さを想定した場合、需要に対する供給力の余裕を示す「予備率」が東京電力管内で「ぎりぎりになる」と試算。全国７エリアで３％台となり、「過去１０年間で最も厳しい」と指摘した。
　電力の安定供給に必要な予備率は３％。試算では、１０年に１度の寒さとなった場合でも「全エリアで３％を確保できる」とした。
　ただ、東電管内の予備率は来年１月が３．２％、２月が３．１％まで低下。さらに２月は中部、北陸、関西、中国、四国、九州の各電力管内でも３．９％と４％を切るなど、「極めて厳しい」との見方を示した。（2021/10/26-18:28）

Electricity demand in the area covered by Tokyo Electric Power Company Holdings Inc. may approach maximum supply this winter, a government estimate found Tuesday.
   The electricity reserve rate, or excess capacity over demand, is projected to come close to falling below the 3 pct threshold for maintaining a stable power supply in the TEPCO service area if Japan experiences a once-in-a-decade cold wave.
   The power supply and demand outlook for this winter was released at a meeting of experts in the industry ministry.
   The estimate found that, while all regions in Japan can maintain a reserve rate of at least 3 pct, the area served by TEPCO will likely see the reserve rate fall to 3.2 pct in January and 3.1 pct in February.
   The rate is estimated to drop below 4 pct in areas covered by Chubu Electric Power Co. , Hokuriku Electric Power Co. , Kansai Electric Power Co. , Chugoku Electric Power Co. , Shikoku Electric Power Co. and Kyushu Electric Power Co. as well.
