受連(lian)日高(gao)溫天(tian)氣影響，5月(yue)20 日，北(bei)京(jing)(jing)電(dian)網(wang)最大(da)(da)負荷(he)達到1005.2萬千(qian)(qian)瓦，較(jiao)去(qu)年(nian)(nian)5月(yue)份平均最大(da)(da)負荷(he)增長7.25%。這是北(bei)京(jing)(jing)電(dian)網(wang)負荷(he)今年(nian)(nian)春季以來首(shou)次突(tu)破1000萬千(qian)(qian)瓦，較(jiao)去(qu)年(nian)(nian)同期提前(qian)6天(tian)，標志著北(bei)京(jing)(jing)電(dian)網(wang)提前(qian)進入夏季大(da)(da)負荷(he)運行階(jie)段。截至目前(qian)，北(bei)京(jing)(jing)電(dian)網(wang)運行平穩(wen)。
從目前負荷(he)增長(chang)趨勢(shi)(shi)和氣(qi)(qi)(qi)溫變化情況(kuang)看，今(jin)年(nian)大(da)負荷(he)的(de)較早(zao)出(chu)現主(zhu)要受天氣(qi)(qi)(qi)情況(kuang)影響。本周北京地區受暖氣(qi)(qi)(qi)團影響，日最(zui)(zui)高氣(qi)(qi)(qi)溫平均34.02℃，拉動地區負荷(he)水(shui)平節節攀(pan)升。20日出(chu)現薄霧天氣(qi)(qi)(qi)，空氣(qi)(qi)(qi)濕(shi)度增加至30%，天氣(qi)(qi)(qi)悶熱(re)，負荷(he)水(shui)平突(tu)破1000萬千(qian)瓦。今(jin)年(nian)夏(xia)季期(qi)間，綜合考慮經濟走(zou)勢(shi)(shi)、氣(qi)(qi)(qi)象(xiang)等多種(zhong)因素，初步預(yu)測北京電(dian)網最(zui)(zui)大(da)負荷(he)將達1400萬千(qian)瓦，較2008年(nian)最(zui)(zui)大(da)負荷(he)1256萬千(qian)瓦增長(chang)11.46%。
