    “到2020年以后,能够提供能源输出的省份已经越来越少,藏电外送具有广阔的市场空间。”中国水电工程顾问集团公司副总经理晏志勇日前在“和谐电力论坛”上透露,西藏水电外送已经具备了一定的基础,将通过接力式或直送式两种方式进行。 

     

      中国证券报报导,晏志勇进一步解释说,接力式外送是指,部分藏电满足云南、四川在2020年以后的电力需要,部分再通过云南、四川送往中国南方电网、华中四省电网或华东区域电网。他认为,2020年以后,四川、云南两省为了满足本省经济社会发展的需要很难再新增“西电东送”的规模,可考虑建设西藏至四川、西藏至云南和西藏直接东送的输电线路,以保持“西电东送”的持续送电。直送式则是通过特高压输电系统直接将藏电外送中国南方电网、华中四省电网或华东区域电网。

    藏电外送初步设想分三个阶段进行。晏志勇透露,第一阶段可通过古水水电站和松塔水电站的建设,实现藏电外送零的突破;第二阶段将从金沙江、澜沧江、怒江上游进行外送。他说,金沙江、澜沧江和怒江中下游干流各水电站大部分将在2020年前建成或开工建设,这将逐步形成送电华中、华东区域电网和中国南方电网的输电通道,为西藏境内的水电开发创造了条件。第三阶段是进行雅鲁藏布江水电的开发外送。但晏志勇并没有详细介绍各阶段的时间表。 

     

      据晏志勇介绍,西藏水力资源理论蕴藏量17640亿千瓦时,居全国首位;技术可开发装机容量11000万千瓦、年发电量5760亿千瓦时,居全国第二位。
