2月19日，浙(zhe)江(jiang)北春、天曉兩(liang)條(tiao)(tiao)500千(qian)伏輸電(dian)線(xian)路經過22晝夜的艱苦搶修，于(yu)當(dang)晚21時11分正式投(tou)入運(yun)行(xing)。這(zhe)兩(liang)條(tiao)(tiao)線(xian)路的恢復投(tou)運(yun)，使浙(zhe)江(jiang)寧波電(dian)網500千(qian)伏網架結構恢復正常，電(dian)網穩定性(xing)得到(dao)進一(yi)步提高。
這兩條(tiao)線路的(de)(de)(de)受損(sun)電塔(ta)海拔超過500米(mi)，位(wei)于寧(ning)波(bo)北侖(lun)地區的(de)(de)(de)一個常年風力很大的(de)(de)(de)山口，在搶(qiang)修(xiu)施工(gong)(gong)過程中，連續多天遭遇7-11級(ji)大風，每班電力搶(qiang)修(xiu)施工(gong)(gong)工(gong)(gong)人(ren)只(zhi)能在塔(ta)上工(gong)(gong)作半小時，國(guo)家電網公司的(de)(de)(de)浙江送變(bian)電公司現場施工(gong)(gong)人(ren)員克服(fu)了重(zhong)重(zhong)困難，在加強安全措施的(de)(de)(de)前(qian)提(ti)下，多班次輪流上塔(ta)搶(qiang)修(xiu)，終于在正月十五大負(fu)荷來臨之前(qian)，將線路搶(qiang)通投(tou)運(yun)。
該線路的(de)(de)恢復投(tou)運，使(shi)失(shi)去達22日之久的(de)(de)浙江春(chun)曉(xiao)變(bian)(bian)恢復500千(qian)伏(fu)聯(lian)絡，寧(ning)波(bo)(bo)電(dian)(dian)(dian)網(wang)500千(qian)伏(fu)網(wang)架結構(gou)恢復正常，電(dian)(dian)(dian)網(wang)穩定性得(de)到進一步提(ti)高(gao)(gao)。春(chun)曉(xiao)變(bian)(bian)供(gong)(gong)區(qu)供(gong)(gong)電(dian)(dian)(dian)能力(li)(li)提(ti)高(gao)(gao)60萬(wan)千(qian)瓦(wa)(wa)(wa)，目前已限(xian)電(dian)(dian)(dian)20萬(wan)千(qian)瓦(wa)(wa)(wa)全(quan)部解放。寧(ning)波(bo)(bo)電(dian)(dian)(dian)網(wang)供(gong)(gong)電(dian)(dian)(dian)能力(li)(li)提(ti)高(gao)(gao)100萬(wan)千(qian)瓦(wa)(wa)(wa)以(yi)上，其中天(tian)一主變(bian)(bian)下送限(xian)額(e)由125萬(wan)千(qian)瓦(wa)(wa)(wa)提(ti)高(gao)(gao)到180萬(wan)千(qian)瓦(wa)(wa)(wa)，春(chun)曉(xiao)變(bian)(bian)下送限(xian)額(e)提(ti)高(gao)(gao)到60萬(wan)千(qian)瓦(wa)(wa)(wa)。北侖電(dian)(dian)(dian)廠(chang)電(dian)(dian)(dian)力(li)(li)送出(chu)能力(li)(li)增加50萬(wan)千(qian)瓦(wa)(wa)(wa)，除滿足(zu)寧(ning)波(bo)(bo)地(di)區(qu)供(gong)(gong)電(dian)(dian)(dian)外，還(huan)可(ke)支(zhi)援全(quan)省發用(yong)電(dian)(dian)(dian)平衡。
目(mu)前，國(guo)家電(dian)(dian)(dian)網營業區域內，停(ting)(ting)運變電(dian)(dian)(dian)站已(yi)恢(hui)(hui)復(fu)(fu)(fu)813座，停(ting)(ting)運輸電(dian)(dian)(dian)線路已(yi)恢(hui)(hui)復(fu)(fu)(fu)14531條，損毀桿塔已(yi)恢(hui)(hui)復(fu)(fu)(fu)165838基，恢(hui)(hui)復(fu)(fu)(fu)率全部超(chao)過90%。國(guo)家電(dian)(dian)(dian)網公司(si)已(yi)累(lei)計恢(hui)(hui)復(fu)(fu)(fu)停(ting)(ting)電(dian)(dian)(dian)用戶(hu)2609萬(wan)戶(hu)，占(zhan)累(lei)計停(ting)(ting)電(dian)(dian)(dian)用戶(hu)的96.44%，其中城市停(ting)(ting)電(dian)(dian)(dian)用戶(hu)已(yi)恢(hui)(hui)復(fu)(fu)(fu)595.24萬(wan)戶(hu)，恢(hui)(hui)復(fu)(fu)(fu)率達(da)到99.96%，已(yi)逼近完勝(sheng)。
