“浙北—福州1000千伏特高壓交流輸變電工程正式投運。”12月26日，隨著國家電網公司董事長、黨組書記劉振亞宣布投運，國家電網公司投資建設的第三個特高壓交流工程正式投入運行。它是華東特高壓交流主網架的重要組成部分，也是對我國特高壓電網大規模建設能力的又一次全面檢驗。
浙北—福州特高壓工程于2013年3月獲得核準。工程包括四站三線，起于浙江浙北變電站，止于福建福州變電站，變電容量1800萬千伏安，全線為雙回路架設，全長2×603千米，近期輸電能力達680萬千瓦，遠期輸電能力可提高到1050萬千瓦以上。
浙(zhe)北(bei)—福(fu)(fu)州特高壓(ya)工(gong)程(cheng)投運后，國家電(dian)(dian)(dian)(dian)(dian)網(wang)已累計(ji)(ji)建(jian)成“三交四直”特高壓(ya)工(gong)程(cheng)，在運在建(jian)的(de)(de)特高壓(ya)輸(shu)電(dian)(dian)(dian)(dian)(dian)線路長度超過1.5萬千米，累計(ji)(ji)送電(dian)(dian)(dian)(dian)(dian)超過2700億千瓦時。浙(zhe)北(bei)—福(fu)(fu)州特高壓(ya)工(gong)程(cheng)將顯著(zhu)提升(sheng)華東電(dian)(dian)(dian)(dian)(dian)網(wang)接受(shou)區外(wai)來(lai)電(dian)(dian)(dian)(dian)(dian)的(de)(de)能(neng)力和區內(nei)資源優化(hua)配置的(de)(de)能(neng)力，保障(zhang)沿海核電(dian)(dian)(dian)(dian)(dian)可(ke)(ke)靠送出(chu)，滿足福(fu)(fu)建(jian)電(dian)(dian)(dian)(dian)(dian)網(wang)盈余(yu)電(dian)(dian)(dian)(dian)(dian)力送出(chu)需要，并(bing)為福(fu)(fu)建(jian)電(dian)(dian)(dian)(dian)(dian)網(wang)遠期接受(shou)外(wai)來(lai)電(dian)(dian)(dian)(dian)(dian)力創造條件。同時，工(gong)程(cheng)在穿越“兩(liang)江一湖(hu)”等走(zou)廊緊張路段采用1000千伏(fu)同塔(ta)雙(shuang)回架設，在極為有限的(de)(de)輸(shu)電(dian)(dian)(dian)(dian)(dian)走(zou)廊范(fan)圍內(nei)，將輸(shu)電(dian)(dian)(dian)(dian)(dian)能(neng)力提升(sheng)4～5倍，大(da)幅提高了浙(zhe)江省內(nei)南北(bei)電(dian)(dian)(dian)(dian)(dian)力交換(huan)的(de)(de)能(neng)力，節約了寶(bao)貴的(de)(de)土地資源。浙(zhe)北(bei)—福(fu)(fu)州特高壓(ya)工(gong)程(cheng)的(de)(de)成功實踐，將進一步鞏固擴大(da)我國在國際特高壓(ya)輸(shu)電(dian)(dian)(dian)(dian)(dian)領(ling)域(yu)的(de)(de)領(ling)先優勢，對推動我國盡快建(jian)成特高壓(ya)電(dian)(dian)(dian)(dian)(dian)網(wang)、轉(zhuan)變能(neng)源發展(zhan)方式、支撐經濟社會(hui)可(ke)(ke)持續發展(zhan)具有重大(da)意義。
