Indian Power System – Recent Disturbance National Electricity Policy

12th February 2005

Electricity is an essential requirement for all facets of our life. It has been recognized as a basic human need.

Recognizing that electricity is one of the key drivers for rapid economic growth and poverty alleviation, the nation has set itself the target of providing access to all households in next five years. As per Census 2001, about 44% of the households do not have access to electricity.

Section 3 of the Electricity Act 2003 requires the Central Government to formulate & revise, the National Electricity Policy in consultation with Central Electricity Authority (CEA) and State Governments.

Indian Power System – Recent Disturbance Prespective

The per capita average annual domestic electricity consumption in India in 2009 was 96 kWh in rural areas and 288 kWh in urban areas for those with access to electricity, in contrast to the worldwide per capita annual average of 2600 kWh and 6200 kWh in the European Union.[7]

India's total domestic, agricultural and industrial per capita energy consumption estimate vary depending on the source. Two sources place it between 400 to 700 kWh in 2008–2009.[8][9]

As of January 2012, one report found the per capita total consumption in India to be 778 kWh.[5]

Indian Power System – Recent Disturbance Summary of Large System Disturbance Workshop

India 2012

The Indian blackouts of 30th and 31st of July were the latest and largest blackouts which occurred so far. Nearly 700 million people were effected by the blackout. It was the largest blackout in global history in terms of the number of people effected, nearly 10 % of the world population. Due to heavy weather and large unscheduled flows three of the five country's electricity grids failed.

Starting with the northern grid a cascading effected caused the blackout of the north-eastern and the eastern grid as well. The blackout on July the 30th caused a loss of 36 GW of generation while on July the 31st even 48 GW were lost. To prevent future blackout several high capacity lines will be built to better connect generation with the load centres.

Number Game

100 - 44% = 56% = 678 Million has access to electricity

NR has 56 GW generation, 36 GW was affected on 30 July

56/205 = 27%; 185 Million : 36/205=17%; 119 Million

NEW has 84 GW generation, 48 GW was affected on 31 July
