當(dang)前，華(hua)(hua)中電(dian)網電(dian)力供應正受(shou)困于缺煤、少水、高溫等因素，湖(hu)(hu)南(nan)、重慶、河(he)南(nan)等省(sheng)(sheng)市已(yi)(yi)經開始拉閘限(xian)電(dian)，湖(hu)(hu)南(nan)已(yi)(yi)啟(qi)動有序供電(dian)方案。華(hua)(hua)中電(dian)網有限(xian)公(gong)司緊(jin)急召集(ji)華(hua)(hua)中六省(sheng)(sheng)市電(dian)力公(gong)司進行磋商，于7月(yue)18日與有關省(sheng)(sheng)電(dian)力公(gong)司簽訂了(le)支援湖(hu)(hu)南(nan)、湖(hu)(hu)北、江西等省(sheng)(sheng)的購售電(dian)確認書，交易電(dian)量共9.7億(yi)千瓦時。
目前，華(hua)中(zhong)電(dian)(dian)(dian)網(wang)用(yong)電(dian)(dian)(dian)負(fu)荷快速增(zeng)長，7月上(shang)旬最大用(yong)電(dian)(dian)(dian)負(fu)荷已經達到7504萬(wan)(wan)千瓦(wa)(wa)，同比增(zeng)長13.94%，湖北、河南(nan)、四(si)川、重慶(qing)等省市用(yong)電(dian)(dian)(dian)量(liang)或負(fu)荷創新高。湖南(nan)電(dian)(dian)(dian)網(wang)迎(ying)峰度夏期間用(yong)電(dian)(dian)(dian)需求將達到1300萬(wan)(wan)千瓦(wa)(wa)，預(yu)計(ji)電(dian)(dian)(dian)力缺口超過300萬(wan)(wan)千瓦(wa)(wa)時(shi)(shi)以上(shang)。從7月2日(ri)零時(shi)(shi)起(qi)，湖南(nan)電(dian)(dian)(dian)網(wang)執行日(ri)用(yong)電(dian)(dian)(dian)量(liang)1.9億千瓦(wa)(wa)時(shi)(shi)有(you)序用(yong)電(dian)(dian)(dian)方案，全省每日(ri)拉閘限(xian)電(dian)(dian)(dian)近(jin)2000條次，日(ri)限(xian)電(dian)(dian)(dian)量(liang)超過4000萬(wan)(wan)千瓦(wa)(wa)時(shi)(shi)，隨著(zhu)氣(qi)溫升高，限(xian)電(dian)(dian)(dian)額還將增(zeng)大。
從供應側(ce)來看，由(you)于煤(mei)價上(shang)漲快(kuai)，加上(shang)汶(wen)川大地震影(ying)(ying)響(xiang)，華中地區送電(dian)(dian)大省河(he)南、四(si)川外送能(neng)力(li)受到(dao)嚴(yan)重影(ying)(ying)響(xiang)，部分(fen)購售電(dian)(dian)合同被迫中斷，部分(fen)購售電(dian)(dian)合同意向無法落實。據統計，7月上(shang)旬，華中電(dian)(dian)網(wang)缺煤(mei)停機容量(liang)達(da)到(dao)535.5萬千(qian)瓦。在水(shui)電(dian)(dian)方面，今(jin)年(nian)華中地區來水(shui)時空分(fen)布不均情況(kuang)突出，湖(hu)北(bei)丹江等(deng)大水(shui)庫(ku)水(shui)位(wei)(wei)低(di)(di)于2007年(nian)同期水(shui)平。湖(hu)南主力(li)水(shui)庫(ku)來水(shui)較常年(nian)偏(pian)少(shao)，目(mu)前主力(li)水(shui)電(dian)(dian)廠水(shui)位(wei)(wei)基本接(jie)近死水(shui)位(wei)(wei)，發(fa)電(dian)(dian)能(neng)力(li)銳減，電(dian)(dian)網(wang)快(kuai)速事故備用能(neng)力(li)降低(di)(di)，安全運(yun)行(xing)風險(xian)加大。四(si)川水(shui)電(dian)(dian)廠來水(shui)比多年(nian)均值少(shao)一至(zhi)兩成。
據(ju)預(yu)計，隨著氣溫升高，華中(zhong)地(di)區(qu)電(dian)(dian)(dian)(dian)力供(gong)應(ying)緊(jin)張的(de)壓力還會加(jia)大，迎峰度(du)夏(xia)和奧運保電(dian)(dian)(dian)(dian)形勢極(ji)為嚴峻。華中(zhong)公司向六(liu)省(sheng)市(shi)電(dian)(dian)(dian)(dian)力公司提(ti)出，將有序供(gong)電(dian)(dian)(dian)(dian)作為當前的(de)首要(yao)任務，繼續發(fa)揚團結治(zhi)網的(de)精神(shen)，進(jin)(jin)一(yi)(yi)步完(wan)善(shan)電(dian)(dian)(dian)(dian)力交易合(he)同條款，建立價格聯動(dong)(dong)機制(zhi)，減輕各方(fang)壓力，共渡難(nan)(nan)關，爭取下半年執行好(hao)各類合(he)同的(de)年度(du)計劃(hua)；電(dian)(dian)(dian)(dian)力供(gong)應(ying)相(xiang)對緊(jin)張的(de)省(sheng)市(shi)要(yao)進(jin)(jin)一(yi)(yi)步推(tui)動(dong)(dong)本(ben)省(sheng)市(shi)電(dian)(dian)(dian)(dian)廠(chang)的(de)燃料(liao)采購工作，合(he)理(li)(li)安排電(dian)(dian)(dian)(dian)煤(mei)庫(ku)存，進(jin)(jin)一(yi)(yi)步優化(hua)運行方(fang)式，加(jia)強用電(dian)(dian)(dian)(dian)管理(li)(li)；電(dian)(dian)(dian)(dian)力供(gong)應(ying)相(xiang)對緩和的(de)省(sheng)市(shi)要(yao)合(he)理(li)(li)安排用煤(mei)和存煤(mei)，適(shi)當推(tui)后冬儲(chu)煤(mei)時間，合(he)理(li)(li)調整開機方(fang)式，支援困難(nan)(nan)省(sheng)市(shi)。目前，華中(zhong)公司的(de)其他應(ying)對措施正(zheng)在(zai)緊(jin)張落(luo)實。
