英文摘要：

Power grid construction in regions without electricity is not only the key problem of harmonizing district economic development, but also has very important social value. According to the power construction problems in regions without electricity whose construction methods were mainly grid extension and renewable energy generation, this paper summarized and presented the project and policy risks of power grid investment in regions without electricity, based on the deep analysis of construction characteristics. The corresponding and feasible investment models were proposed separately for the two construction methods： grid extension and renewable energy generation. In addition, the interest subjects in each model and each subject right and responsibility were analyzed, the advantages and challenges of models were compared as well, in order to broaden the financing channels of power grid construction in regions without electricity, coordinate the interests among the subjects, and obtain the relevant policy support, which could promote the power grid construction in regions without electricity, and provide basis for its investment decisions.
