當前，華中電(dian)(dian)網電(dian)(dian)力供(gong)(gong)應(ying)正受困于(yu)缺(que)煤、少(shao)水、高溫等因(yin)素(su)，湖(hu)南、重慶、河南等省市已(yi)經(jing)開(kai)始(shi)拉閘限(xian)(xian)電(dian)(dian)，湖(hu)南已(yi)啟動有序(xu)供(gong)(gong)電(dian)(dian)方案(an)。華中電(dian)(dian)網有限(xian)(xian)公司緊急(ji)召集華中六(liu)省市電(dian)(dian)力公司進行(xing)磋商，于(yu)7月18日與(yu)有關省電(dian)(dian)力公司簽訂了(le)支援湖(hu)南、湖(hu)北、江西等省的購售電(dian)(dian)確認書，交(jiao)易電(dian)(dian)量共9.7億千(qian)瓦時。
目前，華中電(dian)(dian)(dian)網(wang)(wang)用(yong)電(dian)(dian)(dian)負荷快速增(zeng)長，7月上旬(xun)最(zui)大用(yong)電(dian)(dian)(dian)負荷已經(jing)達到(dao)7504萬千(qian)瓦，同比增(zeng)長13.94%，湖北、河南、四川、重慶等省市用(yong)電(dian)(dian)(dian)量或負荷創新高(gao)。湖南電(dian)(dian)(dian)網(wang)(wang)迎峰度夏期間用(yong)電(dian)(dian)(dian)需求將達到(dao)1300萬千(qian)瓦，預計電(dian)(dian)(dian)力(li)缺口超過300萬千(qian)瓦時以上。從7月2日(ri)零時起(qi)，湖南電(dian)(dian)(dian)網(wang)(wang)執行日(ri)用(yong)電(dian)(dian)(dian)量1.9億千(qian)瓦時有序用(yong)電(dian)(dian)(dian)方案，全省每(mei)日(ri)拉(la)閘限(xian)(xian)(xian)電(dian)(dian)(dian)近2000條次，日(ri)限(xian)(xian)(xian)電(dian)(dian)(dian)量超過4000萬千(qian)瓦時，隨(sui)著氣溫升高(gao)，限(xian)(xian)(xian)電(dian)(dian)(dian)額還將增(zeng)大。
從供應側來看，由(you)于煤價上漲(zhang)快，加上汶川(chuan)(chuan)大地震影響，華(hua)(hua)中地區送電(dian)大省河南、四川(chuan)(chuan)外送能力受到嚴重影響，部(bu)分(fen)購(gou)售電(dian)合同(tong)被迫(po)中斷(duan)，部(bu)分(fen)購(gou)售電(dian)合同(tong)意向無法落實。據統計，7月上旬，華(hua)(hua)中電(dian)網缺(que)煤停機容量(liang)達到535.5萬千瓦。在水(shui)(shui)電(dian)方面，今年(nian)華(hua)(hua)中地區來水(shui)(shui)時空分(fen)布不(bu)均情況(kuang)突出，湖北(bei)丹江等大水(shui)(shui)庫水(shui)(shui)位(wei)低于2007年(nian)同(tong)期(qi)水(shui)(shui)平。湖南主力水(shui)(shui)庫來水(shui)(shui)較常年(nian)偏少，目前主力水(shui)(shui)電(dian)廠水(shui)(shui)位(wei)基本(ben)接近死水(shui)(shui)位(wei)，發電(dian)能力銳(rui)減，電(dian)網快速事故備(bei)用能力降低，安(an)全運行風(feng)險加大。四川(chuan)(chuan)水(shui)(shui)電(dian)廠來水(shui)(shui)比多年(nian)均值少一至(zhi)兩成。
據預計，隨著(zhu)氣(qi)溫升(sheng)高，華中(zhong)地區電(dian)(dian)力(li)供(gong)應(ying)緊張(zhang)的(de)(de)(de)(de)(de)壓力(li)還會加大，迎峰度(du)夏和奧運保電(dian)(dian)形勢極為嚴(yan)峻。華中(zhong)公(gong)司向六省(sheng)(sheng)市(shi)(shi)電(dian)(dian)力(li)公(gong)司提(ti)出，將有序供(gong)電(dian)(dian)作為當前的(de)(de)(de)(de)(de)首要任務(wu)，繼續發揚團結治網的(de)(de)(de)(de)(de)精神，進一步完善(shan)電(dian)(dian)力(li)交易合(he)(he)同條(tiao)款，建立價格聯動(dong)機(ji)制，減(jian)輕(qing)各(ge)方壓力(li)，共(gong)渡難關，爭取(qu)下半年執(zhi)行好各(ge)類(lei)合(he)(he)同的(de)(de)(de)(de)(de)年度(du)計劃(hua)；電(dian)(dian)力(li)供(gong)應(ying)相(xiang)對緊張(zhang)的(de)(de)(de)(de)(de)省(sheng)(sheng)市(shi)(shi)要進一步推(tui)(tui)動(dong)本省(sheng)(sheng)市(shi)(shi)電(dian)(dian)廠(chang)的(de)(de)(de)(de)(de)燃料采購(gou)工作，合(he)(he)理安排電(dian)(dian)煤(mei)庫存，進一步優化運行方式(shi)，加強用(yong)電(dian)(dian)管理；電(dian)(dian)力(li)供(gong)應(ying)相(xiang)對緩和的(de)(de)(de)(de)(de)省(sheng)(sheng)市(shi)(shi)要合(he)(he)理安排用(yong)煤(mei)和存煤(mei)，適當推(tui)(tui)后冬儲煤(mei)時(shi)間，合(he)(he)理調(diao)整(zheng)開機(ji)方式(shi)，支援(yuan)困難省(sheng)(sheng)市(shi)(shi)。目前，華中(zhong)公(gong)司的(de)(de)(de)(de)(de)其(qi)他應(ying)對措施正在緊張(zhang)落實。
