日前，《凱里電網規劃（2009－2013年）（初審稿）》通過南方電網所屬貴州電網公司組織的評審。根據規劃，未來五年凱里供電局將投入50億元用于電網建設改造。
屆時，凱(kai)里電(dian)(dian)(dian)網將(jiang)形成以(yi)500千(qian)伏(fu)電(dian)(dian)(dian)網為(wei)樞紐(niu)，以(yi)220千(qian)伏(fu)環網供(gong)電(dian)(dian)(dian)為(wei)主，區域之間(jian)實現220千(qian)伏(fu)電(dian)(dian)(dian)網互聯；110千(qian)伏(fu)及(ji)35千(qian)伏(fu)電(dian)(dian)(dian)網為(wei)中低壓配電(dian)(dian)(dian)網基(ji)礎的(de)供(gong)電(dian)(dian)(dian)網絡(luo)，供(gong)電(dian)(dian)(dian)能力和供(gong)電(dian)(dian)(dian)可(ke)(ke)靠(kao)性將(jiang)大幅提高(gao)。到(dao)2013年，凱(kai)里城市供(gong)電(dian)(dian)(dian)可(ke)(ke)靠(kao)率將(jiang)由現在的(de)99.858%上升(sheng)至99.945%以(yi)上，客(ke)戶年平均(jun)停電(dian)(dian)(dian)時間(jian)4.818小時，綜合(he)線損率(110千(qian)伏(fu)及(ji)以(yi)下)4.5%，變電(dian)(dian)(dian)站(zhan)主變“N-1”、高(gao)壓線路的(de)“N-1”、10千(qian)伏(fu)線路“N-1”達(da)到(dao)100%。
