Power and Energy Position in Assam
Submitted by pbhagawati on Fri, 01/02/2009 - 11:50
In pursuance of the Indian Electricity Act 2003 and as a part of the Assam Power Sector Development Programme, the Government of Assam has set in motion the process of unbundling the Assam State Electric Board (ASEB) into five Government Companies in 2004. The five companies are - the Assam Power Generation Corporation Limited (APGCL), the Assam Electricity Grid Corporation Limited (AEGCL), Upper Assam Electricity Distribution Company Limited (UAEDCL) for the areas of supply in the Upper Assam Region, the Central Assam Electricity Distribution Company Limited (CAEDCL) for the central areas and the Lower Assam Electricity Distribution Company Limited (LAEDCL) for the areas of supply under the lower Assam Areas. These initiatives are in the interest of all the stakeholders in the electricity sector in the State, i.e. consumers, shareholders, suppliers, creditors, infrastructure builders and the Government of Assam. In the recent past the UAEDCL, CAEDCL, LAEDCL have been merged and renamed as Assam Power Distribution Company Ltd (APDCL). Thus, ASEB has three successor companies at present namely- (1) Assam Power Generation Corporation Limited (APGCL), (2) Assam Electricity Grid Corporation Limited (AEGCL) and (3) Assam Power Distribution Company Ltd (APDCL). However, the schemes like - Externally Aided Project, Rural Electrification, Accelerated Power Development and Reform Programme (APDRP) which are yet being executed under Assam State Electricity Board.
Installed capacity and Generation of Power:
The installed capacity of generating plants at present in the State is 401.50 MW which include Hydel and Gas Plants of the State. The installed capacity for generating power has come down due to de-commissioning of Bongaigaon Thermal Power Station (BTPS) and Mobile Gas Turbine sets and de-rating of age-old units of Namrup (NTPS.)
Although the Chandrapur TPS was shut down due to exorbitant cost of fuel since June 1999 [however the revival process of the Chandrapur TPS through PPP is on by using alternative fuel], the functioning of Hydel Power Project since 2006-07 has brought some changes to the power generation scenario in the State. In 2009-10, the power generation in the state increased to 1712.21 MU from 1682.82 MU in 2008-09 which was only 867.539 MU in 2006-07.

Power supply position:
The energy requirement in the State has been worked out at 5049 Million Units during the year 2009-10 as against 5039 Million Units in the previous year. But the availability of energy during the periods was 4590 Million Units and 4270 Million units respectively. To meet the demand of the requirement of power, the ASEB is purchasing power from other public and private sources.

The overall power supply position has not been satisfactory during the past several years. But since 2007-08, the power supply position has been improving slightly as compared to past years.
Per Capita availability Status:

Power Consumption:
As a result of improvement in the power generation, the Assam Power Generation Corporation Limited (APGCL) could able to sale more power to the consumers during the recent years. During the year 2008-09, the sale of power has increased to 3012551 MWH as against 2711547 MWH sold during 2007-08 which is further increased to 3258786 MWH in 2009-10 thereby registered more than 8.17 per cent increase in the sale of electricity over the year. The statistics of the pattern of consumption during the last three years reveal that the Domestic Sector has been consuming highest amount of power since long back, followed by the Industrial Sector and Commercial Sector in the State.

Transmission and Distribution Losses:
Power, which is supplied to various categories of consumers passes through various stages from transformation to higher voltage level to final distribution in the premises of the consumers, involves energy losses is known as Transmission and Distribution losses. The Transmission and Distribution loss in the State was calculated as 31 percent during the year 2010-11(upto January 2011), which includes commercial losses as well. However, power loss through transmission is an area of concern for the power deficit State like Assam.

Rural Electrification:
Like most of the states of the country, Assam is also lagging behind in respect of rural household’s electrification. In Assam, out of the total 25,124 numbers of inhabited villages (as per 2001 Population Census) 16814 villages [67.0 percent] have been electrified till the end of March, 2010.
