12月12日，為有(you)效(xiao)緩解珠海、澳(ao)門(men)兩地明年起(qi)用電(dian)負(fu)荷壓力，南(nan)方電(dian)網供(gong)電(dian)澳(ao)門(men)2008年輸電(dian)通(tong)道工(gong)程(cheng)開工(gong)，計劃于2008年5月底用電(dian)負(fu)荷高峰來臨前(qian)建成投產。該(gai)項工(gong)程(cheng)投產后，南(nan)方電(dian)網通(tong)過廣(guang)東供(gong)電(dian)澳(ao)門(men)電(dian)壓等級由目前(qian)的(de)110千伏提升到220千伏，供(gong)電(dian)能力將大幅提升，可滿足(zu)澳(ao)門(men)2010年前(qian)的(de)電(dian)力需(xu)求，并留有(you)余地。
根據《南方電(dian)(dian)(dian)(dian)網(wang)(wang)向澳(ao)(ao)門(men)中長(chang)期(qi)輸(shu)電(dian)(dian)(dian)(dian)規劃》，預測2008年廣東供(gong)電(dian)(dian)(dian)(dian)澳(ao)(ao)門(men)最高(gao)(gao)負荷約55萬(wan)千(qian)瓦(wa)，到2010年最高(gao)(gao)負荷將達88萬(wan)千(qian)瓦(wa)。目前南方電(dian)(dian)(dian)(dian)網(wang)(wang)公(gong)司通過廣東電(dian)(dian)(dian)(dian)網(wang)(wang)110千(qian)伏珠澳(ao)(ao)A、B電(dian)(dian)(dian)(dian)纜線路(lu)和110千(qian)伏南屏站(zhan)至凼仔站(zhan)架空線與電(dian)(dian)(dian)(dian)纜混合線路(lu)共三(san)條(tiao)通道對澳(ao)(ao)門(men)供(gong)電(dian)(dian)(dian)(dian)。為進(jin)一步提(ti)高(gao)(gao)對澳(ao)(ao)門(men)電(dian)(dian)(dian)(dian)網(wang)(wang)的供(gong)電(dian)(dian)(dian)(dian)能力和供(gong)電(dian)(dian)(dian)(dian)可靠性，滿足澳(ao)(ao)門(men)2008年及(ji)中長(chang)期(qi)的用電(dian)(dian)(dian)(dian)需求，廣東電(dian)(dian)(dian)(dian)網(wang)(wang)公(gong)司正(zheng)式(shi)啟動了供(gong)電(dian)(dian)(dian)(dian)澳(ao)(ao)門(men)2008年輸(shu)電(dian)(dian)(dian)(dian)通道工(gong)程。
該工程包括新建珠海220千伏拱北變電站至澳門220千伏CP變電站1回220千伏電纜線路，長度約7千米；將110千伏拱北站至澳北站電纜線路升壓為220千伏電纜線路運行，其中一回電纜線路接220千伏拱北變電站，另一回電纜線路改接至220千伏珠海變電站。
