Indian Power System Recent DisturbancePrespective

The per capita average annual domestic electricityconsumption 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 20082009.[8][9]

As ofJanuary 2012, one report found the per capita total

consumption in India to be 778 kWh.[5]

Indian Power System Recent DisturbanceSummary 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 worldpopulation. Due to heavy weatherand 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.
