受強冷空(kong)氣(qi)影響，1月6日起北(bei)京持續極(ji)寒大風天(tian)氣(qi)，1月7日最低氣(qi)溫降至-19℃上下。1月6日20時(shi)22分，北(bei)京電(dian)網(wang)用(yong)電(dian)負(fu)(fu)荷(he)達到2451萬(wan)千瓦，刷新2018年夏季(ji)2356萬(wan)千瓦的最大負(fu)(fu)荷(he)紀(ji)錄，再創(chuang)歷史新高。面(mian)對極(ji)寒天(tian)氣(qi)考驗，國(guo)網(wang)北(bei)京電(dian)力超前謀劃、積極(ji)應對，全力確保電(dian)力可靠供應，確保群眾溫暖度冬，確保防疫(yi)用(yong)電(dian)需(xu)要。目前，北(bei)京電(dian)網(wang)用(yong)電(dian)負(fu)(fu)荷(he)仍保持高位運行，電(dian)網(wang)運行安(an)全平穩，電(dian)力供應有序。
