本項目動態(tai)投資(zi)總計3546134萬元，計劃(hua)于2027年7月建(jian)成投運。

工程主要是為了落實國家《“十四五(wu)”電力發展規(gui)劃》，保障甘肅騰格(ge)里(li)沙漠河西新能源(yuan)基地新能源(yuan)電力可靠送(song)出。

浙(zhe)江電(dian)(dian)網是華東電(dian)(dian)網的重要組(zu)成部(bu)分，截至2023年(nian)底，浙(zhe)江省(sheng)電(dian)(dian)源總裝機容量(liang)為130767MW（不(bu)含(han)新型(xing)儲(chu)能）。2023年(nian)浙(zhe)江省(sheng)全社會(hui)用(yong)電(dian)(dian)量(liang)為6192×10 8kWh，同比增長6.8%;全社會(hui)最大(da)負(fu)荷為110220MW，同比增長1.7%。2025年(nian)浙(zhe)江省(sheng)全社會(hui)用(yong)電(dian)(dian)量(liang)和(he)最大(da)負(fu)荷預測將(jiang)分別達(da)到6660×108kWh和(he)124300MW，“十四五”年(nian)均增長率分別為6.6%和(he)6%。電(dian)(dian)力平衡計(ji)算結果表明，考慮現役、核準在建、納規電(dian)(dian)源及已明確外部(bu)協議(yi)電(dian)(dian)力，2025年(nian)浙(zhe)江電(dian)(dian)網存(cun)在一定電(dian)(dian)力缺口。本工程可緩解受端浙(zhe)江電(dian)(dian)網的供電(dian)(dian)壓力，保(bao)障電(dian)(dian)網安全穩定運行，促進(jin)送、受端地區的經(jing)濟(ji)發展，具有良好的經(jing)濟(ji)效益。
