INTRODUCTION

 

 

 
 

   Scattered in the heart of Bay of Bengal lies a cluster of islands, known as Andaman & Nicobar Islands(A&N Islands). These islands form a long broken chain lies between 92O  to 94O East Longitude and 6O to 14O North Latitude.  The location of these islands are strategically important on the eastern side of India from the view point of defence. With the generous assistance of Central Government these islands have take a large stride on all-round developments in last few decades, which resulted in the tempo of socio- economic transformation. To achieve the above goal, the energy input will be a vital factor.

The A&N Islands have a total area of 8249 sq.kms. out of which the forest cover is about 7589 sq.kms.(92%) .  These islands enjoy a thick forest, rich environment, abundant sea wealth, which boost a high tourist attraction. These islands are divided in three district viz. Andaman, Nicobar and North & Middle Andaman. The seat of the Administration is at Port Blair (South Andaman) in which 14.14 sq.kms. area is under the jurisdiction of Port Blair Municipal Council.

The Electricity Department is operating & maintaining power generation, transmission & distribution system and networks in these islands for providing electric power supply to general public and also implements various schemes under Plan and  Non-Plan  Programmes  for augmentation of the diesel generating capacity and establishment of new Power Houses and T&D systems.  This department also functions as a Nodal Agency for implementing Renewable Energy Programme of the Ministry of New & Renewable Energy Sources.  The Electricity Department is headed by a Superintending Engineer and assisted by 7 Executive Engineers and 38 Assistant Engineers.  The present total installed capacity is around 68.50 MW with a  peak demand of 37 MW.  The installed capacity of the Power Houses ranges between 6 KW to 12500 KW. One Hydro Electric Power Station having a capacity of 5.25 MW is functioning at  Kalpong River, North Andaman.  A 20 MW Diesel Power Station at Bambooflat, South Andaman is being operated by M/s SPCL on PPA basis.  South, Middle & North Andaman are well connected by VHF communication for better monitoring & fault rectification for improved services to the consumers.

Power Generation in A & N Islands is largely through Diesel fuel, which accounts for 95% out of total generation, rest 5% being Hydel generation. In a diesel generation scenario the major cost of power generation is the fuel cost which works out to around 80% of the total cost. The illustrations given below give a detailing of the cost of HSD at various Islands and the specific fuel consumption of the various powers plants of a particular year. There are 41 Diesel Power Houses at different locations in these islands having DG capacity ranging from 6 KW to 5000 KW (including 20 MW IPP) and one Hydro Power Station having 5.25 MW capacity at Kalpong.  The aggregate installed capacity is 68.50 MW (2007-08).  The details of power scenario in major islands are tabulated below:

Round the clock power supply through DG Sets is provided to population in the islands at South Andaman, Middle Andaman, Long Island, Neil Island, Havelock, Little Andaman, Car Nicobar, Katchal, Kamorta & Campbell Bay, which account for about 85% of total population.  At other locations covering 10% population electric power supply is available for 5 to 16 hrs. per day through small DG Power Houses & Solar Power Plants & Home Lighting systems. 4% population need not to be electrified due to Encroached Forest Area as per the directives of Supreme Court of India. Remaining 1% population is programmed for electrification by March, 2009.

As per survey conducted by the National Sample Survey Organization, Govt. of India between July, 2002 & December, 2002 on availability of various infrastructure/resources, it is reported that 95% of villages in A&N Islands have accessibility to electricity against an all India average of only 78%.
