Which are responsible for cause of the blackout?

   Rotation blackout happened for 5 hours on September 15, 2011. Because of the blackout, many citizens were damaged. Many traffic lights went out, so it causes the traffic congestion and many people were stuck in the elevator. also small company were damaged. The total number of damaged companies were 4,588 and Total sum of damage is estimated at 30.1 billion won. Then, which are cause of the blackout ? I think that KEPCO and electricity power consumers cause the blackout.
 
Electricity generation companies always have to prepare the estimated power supply capability, so have to prepare 700,000,000 kw. But when the Rotation blackout happened, electricity generation companies generate only 67,520,000 KW, so when the Rotation blackout happened, only 2,400,000KW reserve power remained. If reserve power is zero, all of city in korea blackout at the same time, not just Rotation blackout. Then, why power companies were unable to supply power sufficiently? Because Electricity generation company had reduced supply for scheduled maintenance work, so generation company generated only 67,520,000 KW. As a result, the blackout happened. Also, electricity power consumers were using too much air conditioner due to an unseasonable heat wave. As a result, KEPCO could not afford to supply the Electricity power, so blackout happened.
 
In order to prevent the blackout, electricity power consumers reduce the excessive consumption and KEPCO has decided to take measures for ensuring a stable supply of electricity.

Korea English education has focused on the test , so many students have prepared test to enter the university. It is not practical english study and make difficult to develop english ability. But removing test is impossible.In order to develop english ability and give practical english education ,  Korea high school English test has to change to the neat. Neat is writing,speaking, reading,listening test, so if Korea high school English test will change to the neat, students will study writing,speaking, reading,listening,  not just reading and listening. second solution is the admision office system.
