當(dang)前，華(hua)中電(dian)(dian)網電(dian)(dian)力(li)供應正受(shou)困于缺煤、少水、高溫等因素，湖(hu)(hu)南、重慶、河南等省(sheng)(sheng)市(shi)已經開始拉閘限(xian)電(dian)(dian)，湖(hu)(hu)南已啟動(dong)有序供電(dian)(dian)方案。華(hua)中電(dian)(dian)網有限(xian)公司緊急(ji)召集華(hua)中六(liu)省(sheng)(sheng)市(shi)電(dian)(dian)力(li)公司進行(xing)磋商，于7月(yue)18日與有關(guan)省(sheng)(sheng)電(dian)(dian)力(li)公司簽訂(ding)了(le)支援湖(hu)(hu)南、湖(hu)(hu)北、江西(xi)等省(sheng)(sheng)的(de)購售(shou)電(dian)(dian)確認書，交易電(dian)(dian)量共(gong)9.7億千瓦(wa)時(shi)。
目前，華中電(dian)(dian)網(wang)用(yong)電(dian)(dian)負(fu)荷快速增長，7月(yue)上旬(xun)最大用(yong)電(dian)(dian)負(fu)荷已經達(da)到(dao)7504萬(wan)(wan)千(qian)(qian)瓦(wa)(wa)，同比(bi)增長13.94%，湖北、河南(nan)(nan)、四川、重慶等(deng)省(sheng)市用(yong)電(dian)(dian)量或負(fu)荷創新高(gao)。湖南(nan)(nan)電(dian)(dian)網(wang)迎(ying)峰度夏(xia)期間(jian)用(yong)電(dian)(dian)需(xu)求將達(da)到(dao)1300萬(wan)(wan)千(qian)(qian)瓦(wa)(wa)，預計電(dian)(dian)力缺口超過300萬(wan)(wan)千(qian)(qian)瓦(wa)(wa)時(shi)以上。從(cong)7月(yue)2日(ri)零時(shi)起，湖南(nan)(nan)電(dian)(dian)網(wang)執行日(ri)用(yong)電(dian)(dian)量1.9億千(qian)(qian)瓦(wa)(wa)時(shi)有序用(yong)電(dian)(dian)方案，全省(sheng)每日(ri)拉閘限(xian)電(dian)(dian)近(jin)2000條(tiao)次，日(ri)限(xian)電(dian)(dian)量超過4000萬(wan)(wan)千(qian)(qian)瓦(wa)(wa)時(shi)，隨著氣(qi)溫升(sheng)高(gao)，限(xian)電(dian)(dian)額還將增大。
從(cong)供應側來看，由于煤(mei)價上漲快(kuai)，加上汶川大地震影響，華中地區送電(dian)(dian)(dian)大省河南(nan)(nan)、四川外送能(neng)力(li)(li)(li)受到嚴(yan)重影響，部(bu)分購(gou)售電(dian)(dian)(dian)合同(tong)(tong)被迫(po)中斷(duan)，部(bu)分購(gou)售電(dian)(dian)(dian)合同(tong)(tong)意向無(wu)法落實。據統計，7月上旬(xun)，華中電(dian)(dian)(dian)網缺煤(mei)停機(ji)容量達到535.5萬千瓦。在水(shui)(shui)(shui)電(dian)(dian)(dian)方面，今(jin)年(nian)華中地區來水(shui)(shui)(shui)時空分布不均(jun)(jun)情況(kuang)突出(chu)，湖北丹江等大水(shui)(shui)(shui)庫水(shui)(shui)(shui)位低(di)于2007年(nian)同(tong)(tong)期水(shui)(shui)(shui)平(ping)。湖南(nan)(nan)主(zhu)力(li)(li)(li)水(shui)(shui)(shui)庫來水(shui)(shui)(shui)較常(chang)年(nian)偏少，目前主(zhu)力(li)(li)(li)水(shui)(shui)(shui)電(dian)(dian)(dian)廠水(shui)(shui)(shui)位基(ji)本接近死水(shui)(shui)(shui)位，發電(dian)(dian)(dian)能(neng)力(li)(li)(li)銳減，電(dian)(dian)(dian)網快(kuai)速事故備用能(neng)力(li)(li)(li)降(jiang)低(di)，安(an)全運行風險加大。四川水(shui)(shui)(shui)電(dian)(dian)(dian)廠來水(shui)(shui)(shui)比多年(nian)均(jun)(jun)值少一(yi)至兩成(cheng)。
據預計，隨著氣溫(wen)升高，華中地區電(dian)(dian)力(li)供應(ying)緊(jin)張(zhang)(zhang)的壓力(li)還會加大，迎峰(feng)度夏(xia)和(he)(he)奧運保電(dian)(dian)形勢極為嚴峻(jun)。華中公(gong)司向六省(sheng)(sheng)市電(dian)(dian)力(li)公(gong)司提出，將有(you)序供電(dian)(dian)作為當(dang)前(qian)的首(shou)要任(ren)務，繼續發揚團結治網的精(jing)神，進一步完善電(dian)(dian)力(li)交易合(he)(he)同條款，建立價(jia)格聯動機(ji)(ji)制，減輕各方(fang)壓力(li)，共渡(du)難(nan)關，爭取下半(ban)年(nian)執行好各類(lei)合(he)(he)同的年(nian)度計劃；電(dian)(dian)力(li)供應(ying)相對(dui)緊(jin)張(zhang)(zhang)的省(sheng)(sheng)市要進一步推動本省(sheng)(sheng)市電(dian)(dian)廠的燃料采(cai)購(gou)工(gong)作，合(he)(he)理安(an)排(pai)電(dian)(dian)煤(mei)庫存，進一步優化運行方(fang)式，加強用電(dian)(dian)管(guan)理；電(dian)(dian)力(li)供應(ying)相對(dui)緩和(he)(he)的省(sheng)(sheng)市要合(he)(he)理安(an)排(pai)用煤(mei)和(he)(he)存煤(mei)，適當(dang)推后(hou)冬儲煤(mei)時間，合(he)(he)理調(diao)整開機(ji)(ji)方(fang)式，支援困(kun)難(nan)省(sheng)(sheng)市。目前(qian)，華中公(gong)司的其他應(ying)對(dui)措施正(zheng)在緊(jin)張(zhang)(zhang)落實。
