受連日(ri)(ri)高溫天氣影響，5月20 日(ri)(ri)，北(bei)京(jing)電網(wang)(wang)最大負(fu)荷(he)(he)達到(dao)1005.2萬(wan)千(qian)瓦，較去年(nian)5月份平均最大負(fu)荷(he)(he)增長7.25%。這是北(bei)京(jing)電網(wang)(wang)負(fu)荷(he)(he)今年(nian)春季以來首次突破1000萬(wan)千(qian)瓦，較去年(nian)同(tong)期提前(qian)6天，標志著北(bei)京(jing)電網(wang)(wang)提前(qian)進入夏季大負(fu)荷(he)(he)運行(xing)(xing)階段。截至目前(qian)，北(bei)京(jing)電網(wang)(wang)運行(xing)(xing)平穩。
從目前負(fu)(fu)(fu)荷增(zeng)長趨(qu)勢和氣(qi)溫(wen)變化情況看，今年(nian)大負(fu)(fu)(fu)荷的(de)較早出(chu)(chu)現主要(yao)受(shou)天氣(qi)情況影響。本周北京地區受(shou)暖(nuan)氣(qi)團影響，日(ri)最(zui)高氣(qi)溫(wen)平(ping)均34.02℃，拉動地區負(fu)(fu)(fu)荷水(shui)平(ping)節(jie)節(jie)攀升。20日(ri)出(chu)(chu)現薄霧天氣(qi)，空氣(qi)濕度(du)增(zeng)加至(zhi)30%，天氣(qi)悶熱，負(fu)(fu)(fu)荷水(shui)平(ping)突破(po)1000萬千(qian)瓦。今年(nian)夏季(ji)期(qi)間(jian)，綜(zong)合考慮經(jing)濟走勢、氣(qi)象等多種因素(su)，初步(bu)預測北京電網(wang)最(zui)大負(fu)(fu)(fu)荷將達1400萬千(qian)瓦，較2008年(nian)最(zui)大負(fu)(fu)(fu)荷1256萬千(qian)瓦增(zeng)長11.46%。
