1）可以長距離、大容量輸送電力
R88M-WP75030T內(nèi)地76%的煤炭資源在北部和西北部，80%的水能資源在西南部，而70%以上的能源需求在中東部，普通電網(wǎng)的傳輸距離只有500公里左右，無法滿足傳輸要求。1000千伏交流特高壓的輸電功率是500千伏交流的4～5倍，經(jīng)濟(jì)輸電距離是500千伏交流的3倍。
2）降低輸送損耗
R88M-WP75030T在導(dǎo)線總截面、輸送容量均相同的情況下，±800千伏直流線路的電阻損耗是±500千伏直流線路的39%，是±600千伏級直流線路的60%，提高輸電效率，節(jié)省運(yùn)行費(fèi)用。
3）節(jié)省工程投資
800千伏直流輸電方案的單位輸送容量投資約為±500千伏直流輸電方案的72%。溪洛渡、向家壩、烏東德、白鶴灘水電站送出工程采用±800千伏級直流與采用±620千伏級直流相比，輸電線路可以從10回減少到6回，并節(jié)約綜合投資約150億元。
4）走廊利用率高
±800千伏、640萬千瓦直流輸電方案的線路走廊為76米，單位走廊寬度輸送容量為8.4萬千瓦/米，是±500千伏、300萬千瓦方案和±620千伏、380萬千瓦方案的1.3倍左右，提高輸電走廊利用效率，節(jié)省寶貴的土地資源；由于單回線路輸送容量大，顯著節(jié)省山谷、江河跨越點(diǎn)的有限資源。
5）統(tǒng)籌利用環(huán)境容量，優(yōu)化煤電布局特高壓優(yōu)勢
