近日，青海、陜西(xi)兩省簽訂中(zhong)長(chang)期電(dian)能互濟(ji)框架協議(yi)。結合青海電(dian)網(wang)(wang)、陜西(xi)電(dian)網(wang)(wang)季節性發(fa)用電(dian)的互補特性，本著“互惠互利、多方共(gong)贏(ying)”原則，雙方將在2020年(nian)—2022年(nian)實(shi)施電(dian)能互濟(ji)，通過充分發(fa)揮大電(dian)網(wang)(wang)資源優化配(pei)置作用，促進青海清(qing)潔能源外送消(xiao)納，提(ti)高(gao)(gao)陜西(xi)發(fa)電(dian)企業經營效益水平，確保±800千伏(fu)青豫特高(gao)(gao)壓直流工(gong)程投運(yun)后平穩運(yun)行。

作為落實黨中(zhong)央(yang)國(guo)務院(yuan)“推進能(neng)源生產和(he)消費革命，構建清潔低碳、安全(quan)高效的(de)(de)能(neng)源體(ti)系”決策部(bu)署的(de)(de)具體(ti)實踐，在國(guo)網(wang)西北分部(bu)的(de)(de)統一協(xie)調下，青(qing)海(hai)電(dian)(dian)(dian)網(wang)、陜西電(dian)(dian)(dian)網(wang)開展(zhan)(zhan)電(dian)(dian)(dian)能(neng)互濟。根據框架協(xie)議(yi)，青(qing)海(hai)、陜西兩(liang)省(sheng)(sheng)將結合各(ge)自電(dian)(dian)(dian)網(wang)發(fa)展(zhan)(zhan)情況，省(sheng)(sheng)間年(nian)度互濟交(jiao)易電(dian)(dian)(dian)量分基(ji)本(ben)電(dian)(dian)(dian)量和(he)增量電(dian)(dian)(dian)量兩(liang)部(bu)分。2020年(nian)—2022年(nian)，預計青(qing)電(dian)(dian)(dian)送陜年(nian)度交(jiao)易電(dian)(dian)(dian)量規模分別為21億(yi)千(qian)瓦(wa)(wa)時(shi)、10億(yi)千(qian)瓦(wa)(wa)時(shi)、5億(yi)千(qian)瓦(wa)(wa)時(shi)；陜電(dian)(dian)(dian)送青(qing)分別為32億(yi)千(qian)瓦(wa)(wa)時(shi)、35億(yi)千(qian)瓦(wa)(wa)時(shi)、35億(yi)千(qian)瓦(wa)(wa)時(shi)。兩(liang)省(sheng)(sheng)中(zhong)有(you)一省(sheng)(sheng)存在臨時(shi)性電(dian)(dian)(dian)力電(dian)(dian)(dian)量缺口(kou)時(shi)，可開展(zhan)(zhan)增量電(dian)(dian)(dian)量交(jiao)易需(xu)求，雙方均優(you)先滿足對方省(sheng)(sheng)份購電(dian)(dian)(dian)需(xu)求。

據了解(jie)，青(qing)(qing)(qing)海(hai)(hai)(hai)(hai)電(dian)(dian)網(wang)(wang)與陜(shan)(shan)西(xi)電(dian)(dian)網(wang)(wang)電(dian)(dian)源結構特性不(bu)同，電(dian)(dian)力電(dian)(dian)量(liang)平衡總體呈季(ji)(ji)節(jie)性變化。夏季(ji)(ji)，青(qing)(qing)(qing)海(hai)(hai)(hai)(hai)進(jin)入(ru)豐水(shui)(shui)期，黃(huang)河水(shui)(shui)電(dian)(dian)大發(fa)，青(qing)(qing)(qing)海(hai)(hai)(hai)(hai)電(dian)(dian)網(wang)(wang)總體電(dian)(dian)量(liang)富余，全天需大量(liang)外送(song)電(dian)(dian)量(liang)，結合龍羊峽(xia)水(shui)(shui)庫運行(xing)情況，向陜(shan)(shan)西(xi)外送(song)清潔能(neng)源，可滿足(zu)陜(shan)(shan)西(xi)夏季(ji)(ji)用電(dian)(dian)增(zeng)長及電(dian)(dian)量(liang)缺(que)(que)口(kou)問(wen)題(ti)，提升(sheng)青(qing)(qing)(qing)海(hai)(hai)(hai)(hai)清潔能(neng)源消納(na)水(shui)(shui)平，提高陜(shan)(shan)西(xi)清潔能(neng)源消納(na)占比。冬季(ji)(ji)，青(qing)(qing)(qing)海(hai)(hai)(hai)(hai)進(jin)入(ru)枯(ku)水(shui)(shui)期，黃(huang)河水(shui)(shui)電(dian)(dian)減(jian)發(fa)，青(qing)(qing)(qing)海(hai)(hai)(hai)(hai)電(dian)(dian)網(wang)(wang)總體缺(que)(que)電(dian)(dian)，而陜(shan)(shan)西(xi)電(dian)(dian)網(wang)(wang)冬季(ji)(ji)火電(dian)(dian)大開機(ji)，外送(song)能(neng)力較強(qiang)，在(zai)青(qing)(qing)(qing)海(hai)(hai)(hai)(hai)電(dian)(dian)網(wang)(wang)獨自承擔青(qing)(qing)(qing)豫(yu)直流外送(song)的前提下，國網(wang)(wang)陜(shan)(shan)西(xi)電(dian)(dian)力按照省內發(fa)電(dian)(dian)能(neng)力組織電(dian)(dian)量(liang)送(song)青(qing)(qing)(qing)，可補充(chong)青(qing)(qing)(qing)海(hai)(hai)(hai)(hai)冬季(ji)(ji)用電(dian)(dian)缺(que)(que)口(kou)。
