東電管内、２８日も節電要請　逼迫「注意報」継続、夕方厳しく―政府

　政府は２７日、東京電力管内で２８日も家庭と企業に節電への協力を要請すると発表した。電力需給が厳しいことを伝える初の「電力需給逼迫（ひっぱく）注意報」発令を２８日も継続。冷房を適切に利用して熱中症に十分注意しつつ、午後３～６時の時間帯を中心に「できる限りの節電」を呼び掛けた。２９日の北海道電力と東北電力、東電の管内に対しては、需給逼迫の可能性を２日前に伝えて注意を促す「電力需給逼迫準備情報」が初めて発令された。
　電力の安定供給には、ピーク需要に対する電力供給の余力を示す「予備率」が最低限３％必要とされる。注意報は予備率が５％を下回る場合に発令。準備情報は、２日後に５％割れが見込まれる場合に出す。（2022/06/27-21:57）

The Japanese government said Monday that it will continue its advisory on tight power supplies Tuesday for the area covered by Tokyo Electric Power Company Holdings Inc. .
   The advisory will be extended as the power reserve rate, which indicates the margin of power supply to capacity, is expected to stand below 5 pct, the threshold for the issuance of the advisory, for the second consecutive day Tuesday due chiefly to rising temperatures.
   Under the advisory, the government calls for households and companies to save electricity as much as possible mainly between 3 p.m. and 6 p.m. while paying enough attention to heatstroke risk.
   On Monday, it became likely as of the morning that Tokyo's highest temperature on the day would be 0.5 Celsius degree higher than the initial forecast, while solar power generation was inadequate in some TEPCO coverage areas.
   There was a possibility that the government would raise the advisory to a warning, which is issued when the reserve rate falls below 3 pct, in order to prevent sudden power problems.
