Indonesia government through the Ministry of Energy and Mineral Resources, in the beginning of year 2016, introduced a program named "Indonesia Terang" or Bright Indonesia. The aimed of this program is to speed up Electrification Rate (ER) with priority to the six provinces at Eastern area of Indonesia including Papua Province. The target of Indonesian's ER by 2019 is 97%. While the Indonesian's national ER already high (88.30%) in 2015, Papua still the lowest ER (45.93%) among the provinces. The scenario to boost up ER in the Eastern area by connected the consumers at villages which not electrified yet to the new Renewable Energy sources. This paper presents an overview of current situation of Electricity Infrastructure and Operation particularly on the mountain area which has high populated compare to coastal area but the average RE below 10%. Case studies of electricity infrastructure profile from mountain area were conducted to identify and reveal the challenge to achieve the Bright Indonesia objectives. Also, the assessment of the visibility according to the high target from this program will be presented.
