12月(yue)12日(ri)，為有效(xiao)緩解珠海、澳門兩(liang)地明(ming)年起用(yong)電(dian)(dian)負(fu)荷壓力，南(nan)方電(dian)(dian)網(wang)供電(dian)(dian)澳門2008年輸電(dian)(dian)通道工程開(kai)工，計(ji)劃于2008年5月(yue)底用(yong)電(dian)(dian)負(fu)荷高(gao)峰來臨前(qian)建成投(tou)產(chan)。該項(xiang)工程投(tou)產(chan)后，南(nan)方電(dian)(dian)網(wang)通過廣(guang)東供電(dian)(dian)澳門電(dian)(dian)壓等級由(you)目(mu)前(qian)的110千(qian)伏(fu)提(ti)升到(dao)220千(qian)伏(fu)，供電(dian)(dian)能力將大幅(fu)提(ti)升，可滿足(zu)澳門2010年前(qian)的電(dian)(dian)力需(xu)求，并留有余地。
根據《南(nan)方(fang)電(dian)(dian)網(wang)(wang)向澳(ao)門(men)(men)中長(chang)期輸(shu)電(dian)(dian)規劃(hua)》，預(yu)測2008年(nian)廣(guang)東供(gong)電(dian)(dian)澳(ao)門(men)(men)最(zui)(zui)高(gao)負荷(he)約55萬(wan)千(qian)(qian)瓦(wa)，到2010年(nian)最(zui)(zui)高(gao)負荷(he)將達88萬(wan)千(qian)(qian)瓦(wa)。目(mu)前南(nan)方(fang)電(dian)(dian)網(wang)(wang)公司通(tong)(tong)過廣(guang)東電(dian)(dian)網(wang)(wang)110千(qian)(qian)伏珠澳(ao)A、B電(dian)(dian)纜(lan)線(xian)路和110千(qian)(qian)伏南(nan)屏(ping)站(zhan)至凼仔站(zhan)架空線(xian)與電(dian)(dian)纜(lan)混合線(xian)路共三條通(tong)(tong)道對(dui)澳(ao)門(men)(men)供(gong)電(dian)(dian)。為(wei)進一步提(ti)高(gao)對(dui)澳(ao)門(men)(men)電(dian)(dian)網(wang)(wang)的(de)供(gong)電(dian)(dian)能力和供(gong)電(dian)(dian)可靠性，滿足(zu)澳(ao)門(men)(men)2008年(nian)及中長(chang)期的(de)用電(dian)(dian)需求，廣(guang)東電(dian)(dian)網(wang)(wang)公司正式啟動了供(gong)電(dian)(dian)澳(ao)門(men)(men)2008年(nian)輸(shu)電(dian)(dian)通(tong)(tong)道工程。
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。
