當(dang)前(qian)，華(hua)中(zhong)電(dian)網電(dian)力供應(ying)正受困(kun)于缺煤(mei)、少水、高溫等因素(su)，湖南(nan)、重慶、河南(nan)等省(sheng)(sheng)市已(yi)經開始拉閘限(xian)電(dian)，湖南(nan)已(yi)啟動有序供電(dian)方案(an)。華(hua)中(zhong)電(dian)網有限(xian)公司(si)緊急召集華(hua)中(zhong)六省(sheng)(sheng)市電(dian)力公司(si)進行磋商，于7月18日與有關(guan)省(sheng)(sheng)電(dian)力公司(si)簽訂了支援湖南(nan)、湖北、江(jiang)西等省(sheng)(sheng)的購售電(dian)確認(ren)書，交(jiao)易電(dian)量共9.7億千(qian)瓦時。
目前，華中電(dian)(dian)網(wang)用(yong)電(dian)(dian)負荷(he)(he)(he)快(kuai)速增長(chang)，7月上旬最(zui)大用(yong)電(dian)(dian)負荷(he)(he)(he)已經達(da)到(dao)7504萬千(qian)瓦(wa)，同比增長(chang)13.94%，湖北(bei)、河南、四川、重慶等(deng)省(sheng)市用(yong)電(dian)(dian)量(liang)(liang)或負荷(he)(he)(he)創新高。湖南電(dian)(dian)網(wang)迎峰度夏期間用(yong)電(dian)(dian)需求將達(da)到(dao)1300萬千(qian)瓦(wa)，預計電(dian)(dian)力缺口(kou)超過300萬千(qian)瓦(wa)時以上。從7月2日(ri)零(ling)時起，湖南電(dian)(dian)網(wang)執行日(ri)用(yong)電(dian)(dian)量(liang)(liang)1.9億千(qian)瓦(wa)時有序用(yong)電(dian)(dian)方案，全省(sheng)每日(ri)拉閘限電(dian)(dian)近2000條次，日(ri)限電(dian)(dian)量(liang)(liang)超過4000萬千(qian)瓦(wa)時，隨著氣溫升(sheng)高，限電(dian)(dian)額(e)還將增大。
從供(gong)應側來看(kan)，由于(yu)煤價上(shang)漲快，加上(shang)汶川大(da)地震影(ying)響，華(hua)(hua)中地區(qu)送(song)(song)電(dian)大(da)省河南、四川外送(song)(song)能力受到(dao)嚴重影(ying)響，部(bu)分購(gou)售電(dian)合同(tong)被迫中斷(duan)，部(bu)分購(gou)售電(dian)合同(tong)意向無法(fa)落實。據統計(ji)，7月上(shang)旬，華(hua)(hua)中電(dian)網缺煤停機容量(liang)達到(dao)535.5萬千瓦。在水(shui)(shui)(shui)電(dian)方面，今(jin)年(nian)(nian)(nian)(nian)華(hua)(hua)中地區(qu)來水(shui)(shui)(shui)時空分布不均情況(kuang)突出，湖北(bei)丹(dan)江等(deng)大(da)水(shui)(shui)(shui)庫水(shui)(shui)(shui)位(wei)低(di)于(yu)2007年(nian)(nian)(nian)(nian)同(tong)期水(shui)(shui)(shui)平。湖南主(zhu)(zhu)力水(shui)(shui)(shui)庫來水(shui)(shui)(shui)較常年(nian)(nian)(nian)(nian)偏少，目前(qian)主(zhu)(zhu)力水(shui)(shui)(shui)電(dian)廠水(shui)(shui)(shui)位(wei)基本接(jie)近死水(shui)(shui)(shui)位(wei)，發電(dian)能力銳減(jian)，電(dian)網快速事(shi)故備用能力降(jiang)低(di)，安(an)全運行風險加大(da)。四川水(shui)(shui)(shui)電(dian)廠來水(shui)(shui)(shui)比多年(nian)(nian)(nian)(nian)均值少一至兩成。
據預計，隨著氣(qi)溫升高，華中地區(qu)電(dian)(dian)(dian)(dian)力(li)(li)(li)供(gong)(gong)(gong)應(ying)(ying)緊(jin)張(zhang)的(de)(de)壓力(li)(li)(li)還會加大，迎峰度夏和(he)奧運保(bao)電(dian)(dian)(dian)(dian)形勢(shi)極為(wei)嚴(yan)峻。華中公(gong)司向六省市(shi)(shi)(shi)電(dian)(dian)(dian)(dian)力(li)(li)(li)公(gong)司提出，將有序供(gong)(gong)(gong)電(dian)(dian)(dian)(dian)作(zuo)為(wei)當(dang)前的(de)(de)首要(yao)任(ren)務，繼(ji)續發揚(yang)團結治網的(de)(de)精神，進(jin)一步完善電(dian)(dian)(dian)(dian)力(li)(li)(li)交易合(he)同(tong)條款，建(jian)立(li)價格聯動機制，減輕各方壓力(li)(li)(li)，共(gong)渡(du)難關，爭取下半年(nian)(nian)執行好各類合(he)同(tong)的(de)(de)年(nian)(nian)度計劃(hua)；電(dian)(dian)(dian)(dian)力(li)(li)(li)供(gong)(gong)(gong)應(ying)(ying)相對緊(jin)張(zhang)的(de)(de)省市(shi)(shi)(shi)要(yao)進(jin)一步推動本省市(shi)(shi)(shi)電(dian)(dian)(dian)(dian)廠的(de)(de)燃料采購(gou)工作(zuo)，合(he)理(li)(li)安排(pai)電(dian)(dian)(dian)(dian)煤(mei)庫存，進(jin)一步優(you)化(hua)運行方式，加強用電(dian)(dian)(dian)(dian)管理(li)(li)；電(dian)(dian)(dian)(dian)力(li)(li)(li)供(gong)(gong)(gong)應(ying)(ying)相對緩和(he)的(de)(de)省市(shi)(shi)(shi)要(yao)合(he)理(li)(li)安排(pai)用煤(mei)和(he)存煤(mei)，適當(dang)推后冬儲煤(mei)時間(jian)，合(he)理(li)(li)調整(zheng)開機方式，支援困難省市(shi)(shi)(shi)。目前，華中公(gong)司的(de)(de)其他應(ying)(ying)對措施(shi)正在(zai)緊(jin)張(zhang)落實(shi)。
