據(ju)中國電(dian)力企業聯合會統計數(shu)據(ju)顯示，2008年我國電(dian)力基(ji)本(ben)建(jian)設投(tou)(tou)資(zi)完(wan)成額達5763億(yi)元，同(tong)比增長1.52％。其(qi)中，電(dian)源完(wan)成投(tou)(tou)資(zi)2879億(yi)元，同(tong)比下降10.78％，電(dian)網完(wan)成投(tou)(tou)資(zi)2885億(yi)元，同(tong)比增長17.69％。電(dian)網建(jian)設投(tou)(tou)資(zi)占電(dian)力基(ji)本(ben)建(jian)設投(tou)(tou)資(zi)的50.05％，近幾年首次超過電(dian)源投(tou)(tou)資(zi)。
截至2008年年底，全國(guo)電網(wang)220千(qian)(qian)伏及以上輸(shu)電線(xian)路(lu)回(hui)路(lu)長度已達(da)(da)36.48萬(wan)千(qian)(qian)米，同(tong)比增(zeng)長11.1％，220千(qian)(qian)伏及以上變電設備容量達(da)(da)到138714萬(wan)千(qian)(qian)伏安(an)，同(tong)比增(zeng)長17.8％。
“國(guo)家(jia)出(chu)臺的4萬億投(tou)(tou)資(zi)計劃，加大了對基礎設(she)施(shi)建(jian)設(she)投(tou)(tou)資(zi)力(li)度，電(dian)網(wang)(wang)投(tou)(tou)資(zi)建(jian)設(she)將成為未(wei)來建(jian)設(she)重點(dian)。”據權威人士(shi)透露，未(wei)來兩年，電(dian)網(wang)(wang)建(jian)設(she)投(tou)(tou)資(zi)力(li)度將繼續大增，預計2009年我國(guo)電(dian)源、電(dian)網(wang)(wang)的投(tou)(tou)資(zi)比(bi)例將達到(dao)4:6，電(dian)網(wang)(wang)投(tou)(tou)資(zi)所占比(bi)重有望(wang)再增加10個百分點(dian)。
