About Electricity Department

Scenario of Electricity Department


Power or electricity is the most convenient and versatile form of energy. All form of economic activity whether it be agriculture, industry or services is relied upon the un-interrupted power supply as well as it is the most crucial source of supplying domestic energy requirement. Diesel Generating (DG) sets is the major source of energy in this Union Territory.

The Electricity Department under the Administration looks after the generation and distribution of power in all the 19 inhabited Islands of Andaman & Nicobar. The department also serves as a Nodal Agency for New & Renewable Energy Programmes and is the State Designated Agency (SDA) for Bureau of Energy Efficiency(BEE) for implementation of Energy Efficiency & Conservation Programmes. Due to the geographical and topographical peculiarities of these islands, including separation by sea over great distances, there is no single power grid for all the electrified islands and instead separate power houses cater independently to the power requirements of separate Islands.

In A&N Islands the power generation started during the year 1920 with an installed capacity of 100 KW which has reached at present to 113.72 MW at present to meet the increased power demand in 19 Islands. The power generating & distribution system in each Island is without connection to any grid and therefore a “Stand Alone System”.
