當前，華(hua)中(zhong)(zhong)(zhong)電(dian)網電(dian)力(li)供應正受(shou)困于缺煤(mei)、少(shao)水、高溫(wen)等因素，湖(hu)南、重(zhong)慶、河南等省市(shi)已經開始拉閘限(xian)(xian)電(dian)，湖(hu)南已啟動有序供電(dian)方案。華(hua)中(zhong)(zhong)(zhong)電(dian)網有限(xian)(xian)公司(si)(si)緊急召集華(hua)中(zhong)(zhong)(zhong)六省市(shi)電(dian)力(li)公司(si)(si)進行磋商，于7月18日與有關省電(dian)力(li)公司(si)(si)簽(qian)訂了支援湖(hu)南、湖(hu)北、江西等省的(de)購售電(dian)確(que)認書，交易(yi)電(dian)量共9.7億千瓦時。
目前，華中電(dian)(dian)(dian)網(wang)用(yong)(yong)電(dian)(dian)(dian)負荷快速增長，7月上旬最(zui)大用(yong)(yong)電(dian)(dian)(dian)負荷已經達到(dao)7504萬(wan)千(qian)(qian)(qian)瓦，同比增長13.94%，湖(hu)北、河南、四川、重慶等省市用(yong)(yong)電(dian)(dian)(dian)量(liang)或負荷創新高。湖(hu)南電(dian)(dian)(dian)網(wang)迎(ying)峰(feng)度夏(xia)期(qi)間(jian)用(yong)(yong)電(dian)(dian)(dian)需求將達到(dao)1300萬(wan)千(qian)(qian)(qian)瓦，預計(ji)電(dian)(dian)(dian)力缺口超(chao)過300萬(wan)千(qian)(qian)(qian)瓦時(shi)(shi)以(yi)上。從7月2日零時(shi)(shi)起，湖(hu)南電(dian)(dian)(dian)網(wang)執行(xing)日用(yong)(yong)電(dian)(dian)(dian)量(liang)1.9億(yi)千(qian)(qian)(qian)瓦時(shi)(shi)有序用(yong)(yong)電(dian)(dian)(dian)方案，全(quan)省每(mei)日拉閘限(xian)(xian)電(dian)(dian)(dian)近2000條次(ci)，日限(xian)(xian)電(dian)(dian)(dian)量(liang)超(chao)過4000萬(wan)千(qian)(qian)(qian)瓦時(shi)(shi)，隨著氣溫(wen)升高，限(xian)(xian)電(dian)(dian)(dian)額還(huan)將增大。
從供應(ying)側來(lai)看(kan)，由(you)于煤價上漲快，加(jia)上汶川(chuan)大(da)地震(zhen)影響(xiang)，華中地區送電(dian)(dian)(dian)(dian)大(da)省河南、四川(chuan)外送能力受到(dao)嚴重影響(xiang)，部分購售(shou)電(dian)(dian)(dian)(dian)合(he)(he)同(tong)被迫(po)中斷，部分購售(shou)電(dian)(dian)(dian)(dian)合(he)(he)同(tong)意(yi)向無法落實。據(ju)統計，7月上旬，華中電(dian)(dian)(dian)(dian)網缺煤停(ting)機容量(liang)達到(dao)535.5萬千瓦。在(zai)水(shui)電(dian)(dian)(dian)(dian)方面，今年華中地區來(lai)水(shui)時空分布不均情況突(tu)出，湖北丹江等大(da)水(shui)庫(ku)水(shui)位低(di)于2007年同(tong)期水(shui)平。湖南主(zhu)力水(shui)庫(ku)來(lai)水(shui)較(jiao)常年偏少，目(mu)前(qian)主(zhu)力水(shui)電(dian)(dian)(dian)(dian)廠(chang)水(shui)位基本接(jie)近死水(shui)位，發電(dian)(dian)(dian)(dian)能力銳(rui)減，電(dian)(dian)(dian)(dian)網快速事故備(bei)用(yong)能力降低(di)，安全運行風(feng)險加(jia)大(da)。四川(chuan)水(shui)電(dian)(dian)(dian)(dian)廠(chang)來(lai)水(shui)比(bi)多年均值少一至兩成。
據預(yu)計，隨著氣溫(wen)升高，華(hua)中地區電(dian)(dian)(dian)(dian)力供應緊張(zhang)的壓(ya)力還會加(jia)大，迎峰度夏和(he)奧運保電(dian)(dian)(dian)(dian)形勢極(ji)為嚴峻。華(hua)中公(gong)(gong)司向六省(sheng)市(shi)(shi)電(dian)(dian)(dian)(dian)力公(gong)(gong)司提出，將有序(xu)供電(dian)(dian)(dian)(dian)作為當(dang)前(qian)(qian)的首要(yao)(yao)任(ren)務，繼(ji)續(xu)發揚團(tuan)結治網(wang)的精神，進一(yi)步完善(shan)電(dian)(dian)(dian)(dian)力交易合(he)(he)(he)同條款，建立(li)價(jia)格聯動機制(zhi)，減輕各(ge)(ge)方壓(ya)力，共渡難關，爭取下半年執行好各(ge)(ge)類合(he)(he)(he)同的年度計劃；電(dian)(dian)(dian)(dian)力供應相(xiang)對(dui)(dui)緊張(zhang)的省(sheng)市(shi)(shi)要(yao)(yao)進一(yi)步推動本省(sheng)市(shi)(shi)電(dian)(dian)(dian)(dian)廠的燃料采購工作，合(he)(he)(he)理(li)安排(pai)電(dian)(dian)(dian)(dian)煤庫存，進一(yi)步優(you)化運行方式，加(jia)強用(yong)電(dian)(dian)(dian)(dian)管理(li)；電(dian)(dian)(dian)(dian)力供應相(xiang)對(dui)(dui)緩和(he)的省(sheng)市(shi)(shi)要(yao)(yao)合(he)(he)(he)理(li)安排(pai)用(yong)煤和(he)存煤，適當(dang)推后冬儲(chu)煤時間，合(he)(he)(he)理(li)調整開機方式，支援困難省(sheng)市(shi)(shi)。目(mu)前(qian)(qian)，華(hua)中公(gong)(gong)司的其他應對(dui)(dui)措施正在緊張(zhang)落(luo)實。
