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

the source. Two sources place it between 400 to 700
kWh in 20082009.[8][9]

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.
