當前，華(hua)中(zhong)(zhong)電(dian)網電(dian)力供應正受困于缺煤(mei)、少水、高(gao)溫等因素，湖(hu)(hu)南(nan)、重慶、河南(nan)等省(sheng)市(shi)已(yi)經開始(shi)拉閘(zha)限電(dian)，湖(hu)(hu)南(nan)已(yi)啟動有(you)序供電(dian)方案。華(hua)中(zhong)(zhong)電(dian)網有(you)限公(gong)司緊(jin)急(ji)召集(ji)華(hua)中(zhong)(zhong)六省(sheng)市(shi)電(dian)力公(gong)司進行磋商(shang)，于7月18日與有(you)關省(sheng)電(dian)力公(gong)司簽訂了支援(yuan)湖(hu)(hu)南(nan)、湖(hu)(hu)北、江西(xi)等省(sheng)的購售電(dian)確認(ren)書，交(jiao)易電(dian)量共9.7億千瓦時。
目前，華(hua)中電(dian)網(wang)用(yong)(yong)電(dian)負(fu)(fu)荷(he)快速增(zeng)長，7月上旬最大用(yong)(yong)電(dian)負(fu)(fu)荷(he)已經達(da)到(dao)7504萬千(qian)(qian)(qian)瓦(wa)，同比增(zeng)長13.94%，湖(hu)北、河南(nan)、四(si)川、重慶(qing)等省市用(yong)(yong)電(dian)量(liang)或負(fu)(fu)荷(he)創(chuang)新高(gao)。湖(hu)南(nan)電(dian)網(wang)迎峰度夏(xia)期間用(yong)(yong)電(dian)需求將達(da)到(dao)1300萬千(qian)(qian)(qian)瓦(wa)，預計電(dian)力(li)缺口超(chao)過300萬千(qian)(qian)(qian)瓦(wa)時以(yi)上。從7月2日零時起，湖(hu)南(nan)電(dian)網(wang)執(zhi)行日用(yong)(yong)電(dian)量(liang)1.9億千(qian)(qian)(qian)瓦(wa)時有序(xu)用(yong)(yong)電(dian)方(fang)案，全(quan)省每日拉閘(zha)限(xian)(xian)電(dian)近2000條(tiao)次，日限(xian)(xian)電(dian)量(liang)超(chao)過4000萬千(qian)(qian)(qian)瓦(wa)時，隨著氣溫升高(gao)，限(xian)(xian)電(dian)額還將增(zeng)大。
從供應側(ce)來看，由于煤價(jia)上漲快(kuai)，加(jia)上汶川大地震影響，華中地區(qu)送電(dian)(dian)(dian)大省河南、四川外送能力(li)受到(dao)嚴重(zhong)影響，部分(fen)購售(shou)電(dian)(dian)(dian)合同(tong)被迫中斷，部分(fen)購售(shou)電(dian)(dian)(dian)合同(tong)意向(xiang)無法落實。據統計(ji)，7月上旬(xun)，華中電(dian)(dian)(dian)網(wang)缺煤停機容量(liang)達(da)到(dao)535.5萬千瓦。在水(shui)(shui)(shui)電(dian)(dian)(dian)方面，今年(nian)(nian)華中地區(qu)來水(shui)(shui)(shui)時空分(fen)布不均(jun)情(qing)況突(tu)出(chu)，湖北丹(dan)江等大水(shui)(shui)(shui)庫水(shui)(shui)(shui)位(wei)低于2007年(nian)(nian)同(tong)期水(shui)(shui)(shui)平。湖南主力(li)水(shui)(shui)(shui)庫來水(shui)(shui)(shui)較常年(nian)(nian)偏(pian)少，目前主力(li)水(shui)(shui)(shui)電(dian)(dian)(dian)廠水(shui)(shui)(shui)位(wei)基本接近(jin)死水(shui)(shui)(shui)位(wei)，發電(dian)(dian)(dian)能力(li)銳減，電(dian)(dian)(dian)網(wang)快(kuai)速(su)事故備用(yong)能力(li)降(jiang)低，安全運(yun)行風險加(jia)大。四川水(shui)(shui)(shui)電(dian)(dian)(dian)廠來水(shui)(shui)(shui)比多(duo)年(nian)(nian)均(jun)值少一(yi)至兩成。
據預計(ji)，隨著氣溫升(sheng)高(gao)，華中(zhong)地區電(dian)(dian)(dian)力供應(ying)緊(jin)張的(de)壓(ya)力還會加(jia)大(da)，迎峰度(du)夏(xia)和(he)(he)奧運(yun)(yun)保電(dian)(dian)(dian)形勢極為(wei)嚴(yan)峻。華中(zhong)公司向六省(sheng)(sheng)市(shi)電(dian)(dian)(dian)力公司提出，將有序供電(dian)(dian)(dian)作(zuo)為(wei)當前(qian)的(de)首要(yao)任務，繼(ji)續發(fa)揚團結治網的(de)精神，進一步(bu)完(wan)善電(dian)(dian)(dian)力交易(yi)合(he)同條款，建立(li)價格聯動機(ji)制，減(jian)輕各方壓(ya)力，共渡難關，爭取(qu)下半年執行(xing)好(hao)各類合(he)同的(de)年度(du)計(ji)劃；電(dian)(dian)(dian)力供應(ying)相對緊(jin)張的(de)省(sheng)(sheng)市(shi)要(yao)進一步(bu)推動本(ben)省(sheng)(sheng)市(shi)電(dian)(dian)(dian)廠的(de)燃料(liao)采購工作(zuo)，合(he)理(li)安排電(dian)(dian)(dian)煤庫存，進一步(bu)優化運(yun)(yun)行(xing)方式，加(jia)強用電(dian)(dian)(dian)管理(li)；電(dian)(dian)(dian)力供應(ying)相對緩和(he)(he)的(de)省(sheng)(sheng)市(shi)要(yao)合(he)理(li)安排用煤和(he)(he)存煤，適當推后(hou)冬儲煤時(shi)間，合(he)理(li)調整開機(ji)方式，支(zhi)援困(kun)難省(sheng)(sheng)市(shi)。目前(qian)，華中(zhong)公司的(de)其他應(ying)對措施正在緊(jin)張落實(shi)。
