The State of Arunachal Pradesh is managed by two government departments - Department of Power (DoPAP), responsible for managing the transmission and distribution systems and Department of Hydro Power Development (DHPD), responsible for management and development of hydro power plants in the State. Arunachal Pradesh State Electricity Regulatory Commission (APSERC) is constituted as a one-member body designated to function as an autonomous authority responsible for regulation of the power sector in accordance with the provisions of Electricity Act, 2003.
The existing allocated capacity including central sector allocations for DoPAP stands at 210 MW which includes 67 MW from the State Sector (DHPD & APEDA) projects. Since all the State Sector projects and most of the Central Sector projects are hydel, the State faces power crunch during lean hydro periods.
DoPAP, responsible for the transmission function in the State has 3 intra-state transmission lines and 7 sub-stations at 132 kV and above level with an installed capacity of 167 MVA.
As of October 2017, Arunachal Pradesh had a total installed power generation capacity of 277.96 MW. Out of these central utilities contributed 168.97 MW, private utilities contributed 4.29 MW & state utilities contributed 104.61 MW.
Renewable energy in conjunction with hydropower are the major sources of electricity generation in the state & contributed around 108.99 MW & 97.45 MW to the installed capacity of the state, respectively.
In May 2017, UJAAS received a letter of intent from Arunachal Pradesh Energy Development Agency to design, supply, install, test and commission a 200 kwp-Grid Connected Solar PV Plant at State Assembly Building in Itanagar.
Arunachal Pradesh’s environment ministry panel has approved Nyamjang Chu hydropower project worth US$ 1.06 billion, in the Tawang region of Arunachal Pradesh. Once built, the plant will produce 780 MW of electricity.
Dibang project in Arunachal Pradesh has received the government's approval for diversion of land. A 3,000 MW hydel project will be constructed by NHPC (National Hydroelectric Power Corporation), and is expected to get completed by the end of 2019.
