受強冷空(kong)氣(qi)影響(xiang)，1月6日起(qi)北(bei)京(jing)持續(xu)極寒大風天氣(qi)，1月7日最低氣(qi)溫降(jiang)至-19℃上下。1月6日20時22分，北(bei)京(jing)電(dian)(dian)網用電(dian)(dian)負(fu)(fu)荷達到2451萬千(qian)瓦(wa)，刷(shua)新2018年夏季2356萬千(qian)瓦(wa)的最大負(fu)(fu)荷紀(ji)錄，再創(chuang)歷史(shi)新高(gao)。面(mian)對(dui)極寒天氣(qi)考驗，國(guo)網北(bei)京(jing)電(dian)(dian)力(li)超前謀劃、積極應(ying)(ying)對(dui)，全力(li)確保(bao)(bao)電(dian)(dian)力(li)可靠(kao)供應(ying)(ying)，確保(bao)(bao)群眾(zhong)溫暖度冬，確保(bao)(bao)防疫(yi)用電(dian)(dian)需要。目前，北(bei)京(jing)電(dian)(dian)網用電(dian)(dian)負(fu)(fu)荷仍保(bao)(bao)持高(gao)位運行，電(dian)(dian)網運行安全平穩(wen)，電(dian)(dian)力(li)供應(ying)(ying)有序。

“近20年來，北京(jing)地區電(dian)網最大負(fu)荷(he)首(shou)次出現在冬季，北京(jing)清潔電(dian)能(neng)供暖(nuan)的城(cheng)市(shi)特性日趨明顯。本次電(dian)網負(fu)荷(he)大幅攀升的主要原因是受(shou)極寒天氣影(ying)響，降溫(wen)幅度大、持(chi)續時間(jian)長，居民(min)的采暖(nuan)用電(dian)負(fu)荷(he)集中(zhong)增長，在負(fu)荷(he)高(gao)(gao)峰期間(jian)，采暖(nuan)負(fu)荷(he)占比達到了48.2%，創歷史新高(gao)(gao)。目前，北京(jing)電(dian)網供電(dian)能(neng)力能(neng)夠滿足城(cheng)市(shi)用電(dian)需求，電(dian)力供應充(chong)足，請(qing)廣大市(shi)民(min)放心用電(dian)。”國網北京(jing)電(dian)力調控中(zhong)心主任白晶介紹。
