12月12日，為有效緩解珠海、澳門(men)兩地明年(nian)起用(yong)電(dian)(dian)(dian)負荷壓力，南方電(dian)(dian)(dian)網供(gong)電(dian)(dian)(dian)澳門(men)2008年(nian)輸電(dian)(dian)(dian)通道工程(cheng)開工，計(ji)劃(hua)于2008年(nian)5月底用(yong)電(dian)(dian)(dian)負荷高峰來臨前建(jian)成投產。該項(xiang)工程(cheng)投產后，南方電(dian)(dian)(dian)網通過廣東供(gong)電(dian)(dian)(dian)澳門(men)電(dian)(dian)(dian)壓等級由目前的(de)110千(qian)伏(fu)提升(sheng)到220千(qian)伏(fu)，供(gong)電(dian)(dian)(dian)能力將大幅提升(sheng)，可滿足(zu)澳門(men)2010年(nian)前的(de)電(dian)(dian)(dian)力需求，并留有余地。
根據《南方(fang)電(dian)(dian)網(wang)向澳(ao)(ao)門(men)(men)中(zhong)長期輸電(dian)(dian)規劃》，預測2008年廣(guang)東供(gong)電(dian)(dian)澳(ao)(ao)門(men)(men)最(zui)高(gao)(gao)負(fu)荷約55萬千瓦(wa)，到2010年最(zui)高(gao)(gao)負(fu)荷將達88萬千瓦(wa)。目前南方(fang)電(dian)(dian)網(wang)公司通(tong)過廣(guang)東電(dian)(dian)網(wang)110千伏(fu)珠澳(ao)(ao)A、B電(dian)(dian)纜(lan)(lan)線(xian)路(lu)和110千伏(fu)南屏站(zhan)至凼仔站(zhan)架空線(xian)與電(dian)(dian)纜(lan)(lan)混合線(xian)路(lu)共三條通(tong)道(dao)對澳(ao)(ao)門(men)(men)供(gong)電(dian)(dian)。為進一(yi)步提高(gao)(gao)對澳(ao)(ao)門(men)(men)電(dian)(dian)網(wang)的供(gong)電(dian)(dian)能力和供(gong)電(dian)(dian)可(ke)靠性，滿(man)足澳(ao)(ao)門(men)(men)2008年及中(zhong)長期的用(yong)電(dian)(dian)需求，廣(guang)東電(dian)(dian)網(wang)公司正式啟動了供(gong)電(dian)(dian)澳(ao)(ao)門(men)(men)2008年輸電(dian)(dian)通(tong)道(dao)工程。
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。
