S… Speaker 2 (Eemods 19.5 16_00)

I am from North Korea,

0:11

S… Speaker 2 (Eemods 19.5 16_00)

Hanek University.

0:12

S… Speaker 1 (Eemods 19.5 16_00)

Today I am really pleased to introduce about Korea MAX.

0:16

S… Speaker 1 (Eemods 19.5 16_00)

It is about the evolution of MAX for 3 -phase induction

0:20

S… Speaker 1 (Eemods 19.5 16_00)

motors in Korea.

0:21

S… Speaker 1 (Eemods 19.5 16_00)

From IE3 to IE4 and the inclusion of variable

0:26

S… Speaker 1 (Eemods 19.5 16_00)

speed induction motors.

0:30

S… Speaker 2 (Eemods 19.5 16_00)

Today,

0:31

S… Speaker 1 (Eemods 19.5 16_00)

I am a student for five sectors.

0:34

S… Speaker 1 (Eemods 19.5 16_00)

One is the introduction about water

0:39

S… Speaker 1 (Eemods 19.5 16_00)

and global electricity demand.

0:42

S… Speaker 2 (Eemods 19.5 16_00)

And six and seven,

0:44

S… Speaker 1 (Eemods 19.5 16_00)

two is mass evolution in Korea.

0:46

S… Speaker 1 (Eemods 19.5 16_00)

It's about history of mass in Korea.

0:50

S… Speaker 2 (Eemods 19.5 16_00)

And six and seven,

0:51

S… Speaker 1 (Eemods 19.5 16_00)

three is IE4 and variable scale motors.

0:54

S… Speaker 1 (Eemods 19.5 16_00)

It's about the future,

0:55

S… Speaker 1 (Eemods 19.5 16_00)

what we're going to do in Korea.

0:58

S… Speaker 2 (Eemods 19.5 16_00)

And then section 4,

0:59

S… Speaker 1 (Eemods 19.5 16_00)

like energy saving assessment,

1:01

S… Speaker 1 (Eemods 19.5 16_00)

like how much electricity we have saved so

1:06

S… Speaker 1 (Eemods 19.5 16_00)

far.

1:06

S… Speaker 1 (Eemods 19.5 16_00)

Then 5,

1:08

S… Speaker 1 (Eemods 19.5 16_00)

and policy implications.

1:11

S… Speaker 1 (Eemods 19.5 16_00)

I think here everybody knows

1:15

S… Speaker 1 (Eemods 19.5 16_00)

about like this digit.

1:17

S… Speaker 1 (Eemods 19.5 16_00)

Maybe you may have some different digit,

1:20

S… Speaker 1 (Eemods 19.5 16_00)

but everybody understands.

1:21

S… Speaker 1 (Eemods 19.5 16_00)

I think 53 % of

1:25

S… Speaker 1 (Eemods 19.5 16_00)

the global electricity consumption.

1:28

S… Speaker 1 (Eemods 19.5 16_00)

motor driven system worldwide and 70 % of

1:32

S… Speaker 1 (Eemods 19.5 16_00)

industrial electricity use.

1:35

S… Speaker 1 (Eemods 19.5 16_00)

So why we are talking about this?

1:38

S… Speaker 1 (Eemods 19.5 16_00)

Improving water efficiency is one of the most cost

1:42

S… Speaker 1 (Eemods 19.5 16_00)

effective ways to reduce industrial electricity

1:46

S… Speaker 1 (Eemods 19.5 16_00)

demand and operating cost and CO2 emission.

1:52

S… Speaker 1 (Eemods 19.5 16_00)

I think saving energy from the

1:57

S… Speaker 1 (Eemods 19.5 16_00)

sleeping induction motor is kind of making it a strategic

2:01

S… Speaker 1 (Eemods 19.5 16_00)

level for national energy policy.

2:05

S… Speaker 2 (Eemods 19.5 16_00)

Why could a

2:09

S… Speaker 1 (Eemods 19.5 16_00)

strength motor efficiency policy?

2:11

S… Speaker 1 (Eemods 19.5 16_00)

Actually,

2:12

S… Speaker 1 (Eemods 19.5 16_00)

we have a long history about energy

2:16

S… Speaker 1 (Eemods 19.5 16_00)

efficiency program.

2:21

S… Speaker 2 (Eemods 19.5 16_00)

Actually,

2:21

S… Speaker 1 (Eemods 19.5 16_00)

the first one is from 1996.

2:24

S… Speaker 1 (Eemods 19.5 16_00)

Korea started to have an

2:28

S… Speaker 1 (Eemods 19.5 16_00)

efficiency program about a voluntary high

2:32

S… Speaker 1 (Eemods 19.5 16_00)

efficiency certification program.

2:34

S… Speaker 1 (Eemods 19.5 16_00)

It wasn't mandatory,

2:36

S… Speaker 1 (Eemods 19.5 16_00)

it was a voluntary program supported by Korean government subsidies.

2:40

S… Speaker 1 (Eemods 19.5 16_00)

But at that time,

2:42

S… Speaker 1 (Eemods 19.5 16_00)

after a few years later,

2:44

S… Speaker 1 (Eemods 19.5 16_00)

Korean government realized

2:46

S… Speaker 1 (Eemods 19.5 16_00)

Actually, just the voluntary program is not very much strong.

2:49

S… Speaker 2 (Eemods 19.5 16_00)

So,

2:50

S… Speaker 1 (Eemods 19.5 16_00)

after that,

2:52

S… Speaker 1 (Eemods 19.5 16_00)

kind of until 2008,

2:56

S… Speaker 1 (Eemods 19.5 16_00)

just like 10 to 15 % was in

3:01

S… Speaker 2 (Eemods 19.5 16_00)

the market.

3:02

S… Speaker 1 (Eemods 19.5 16_00)

I mean, the motor which had certification,

3:06

S… Speaker 1 (Eemods 19.5 16_00)

just 10 to 15%,

3:08

S… Speaker 1 (Eemods 19.5 16_00)

only they get it.

3:09

S… Speaker 1 (Eemods 19.5 16_00)

So,

3:10

S… Speaker 1 (Eemods 19.5 16_00)

in 2004,

3:12

S… Speaker 2 (Eemods 19.5 16_00)

the government...

3:25

S… Speaker 2 (Eemods 19.5 16_00)

So after 10 years,

3:28

S… Speaker 1 (Eemods 19.5 16_00)

2018,

3:30

S… Speaker 1 (Eemods 19.5 16_00)

IE3 also was implemented.

3:34

S… Speaker 2 (Eemods 19.5 16_00)

So this was

3:38

S… Speaker 1 (Eemods 19.5 16_00)

a simple METS timeline.

3:41

S… Speaker 1 (Eemods 19.5 16_00)

1996 to will be 2027.

3:44

S… Speaker 1 (Eemods 19.5 16_00)

The interesting thing is we started from 1996.

3:48

S… Speaker 1 (Eemods 19.5 16_00)

But after 10 years,

3:50

S… Speaker 1 (Eemods 19.5 16_00)

IE2 was introduced.

3:52

S… Speaker 1 (Eemods 19.5 16_00)

After almost 10 years later,

3:54

S… Speaker 2 (Eemods 19.5 16_00)

IE3 was introduced.

3:56

S… Speaker 1 (Eemods 19.5 16_00)

And then after 10 years later,

3:59

S… Speaker 1 (Eemods 19.5 16_00)

IE4 and then the BSD motor

4:04

S… Speaker 1 (Eemods 19.5 16_00)

will be implemented.

4:10

S… Speaker 1 (Eemods 19.5 16_00)

So this one is the history of MEX in Korea.

4:13

S… Speaker 1 (Eemods 19.5 16_00)

So I already explained about MEX

4:18

S… Speaker 1 (Eemods 19.5 16_00)

IE2 was started from 2008.

4:21

S… Speaker 1 (Eemods 19.5 16_00)

And then everyone knew that at that time we

4:26

S… Speaker 1 (Eemods 19.5 16_00)

didn't have an IE system.

4:27

S… Speaker 1 (Eemods 19.5 16_00)

So we called like EFM2 was in

4:31

S… Speaker 1 (Eemods 19.5 16_00)

the IE2.

4:32

S… Speaker 1 (Eemods 19.5 16_00)

We called like a high -uscious motor.

4:35

S… Speaker 1 (Eemods 19.5 16_00)

And then 2008...

4:38

S… Speaker 1 (Eemods 19.5 16_00)

Korean government has started a mandatory system.

4:41

S… Speaker 1 (Eemods 19.5 16_00)

I mean,

4:41

S… Speaker 1 (Eemods 19.5 16_00)

there was such a mandatory mess.

4:44

S… Speaker 2 (Eemods 19.5 16_00)

But,

4:45

S… Speaker 2 (Eemods 19.5 16_00)

I will let you know,

4:49

S… Speaker 1 (Eemods 19.5 16_00)

like, actually,

4:50

S… Speaker 1 (Eemods 19.5 16_00)

2008,

4:51

S… Speaker 1 (Eemods 19.5 16_00)

the Korean government wanted to implement the exercise and

4:55

S… Speaker 1 (Eemods 19.5 16_00)

all the folks.

4:56

S… Speaker 2 (Eemods 19.5 16_00)

But,

4:57

S… Speaker 1 (Eemods 19.5 16_00)

the thing is that we just started...

5:00

S… Speaker 1 (Eemods 19.5 16_00)

from 32 kilowatts to 200 kilowatts.

5:03

S… Speaker 1 (Eemods 19.5 16_00)

That means that at that time,

5:05

S… Speaker 1 (Eemods 19.5 16_00)

you know, usually like big motors made by big manufacturers.

5:09

S… Speaker 1 (Eemods 19.5 16_00)

So small companies made just small motors.

5:13

S… Speaker 1 (Eemods 19.5 16_00)

So when we started to mess,

5:16

S… Speaker 1 (Eemods 19.5 16_00)

usually small companies resist a lot.

5:19

S… Speaker 1 (Eemods 19.5 16_00)

So government made a decision to give some grace period.

5:23

S… Speaker 1 (Eemods 19.5 16_00)

So after two years later,

5:25

S… Speaker 1 (Eemods 19.5 16_00)

0 .74,

5:28

S… Speaker 1 (Eemods 19.5 16_00)

2015 was starting to

5:32

S… Speaker 1 (Eemods 19.5 16_00)

mass.

5:33

S… Speaker 1 (Eemods 19.5 16_00)

And October 2018,

5:40

S… Speaker 1 (Eemods 19.5 16_00)

I3 became the minimum efficiency level

5:44

S… Speaker 1 (Eemods 19.5 16_00)

for the full ranges.

5:46

S… Speaker 1 (Eemods 19.5 16_00)

So raising the efficiency baseline for the most

5:50

S… Speaker 1 (Eemods 19.5 16_00)

domestic and imported motors.

5:57

S… Speaker 1 (Eemods 19.5 16_00)

This one is kind of,

5:58

S… Speaker 1 (Eemods 19.5 16_00)

I will,

5:59

S… Speaker 1 (Eemods 19.5 16_00)

I will explain IE.

6:01

S… Speaker 1 (Eemods 19.5 16_00)

But I think here,

6:02

S… Speaker 1 (Eemods 19.5 16_00)

all departments know about what is IE.

6:04

S… Speaker 1 (Eemods 19.5 16_00)

But,

6:05

S… Speaker 1 (Eemods 19.5 16_00)

you know, we have IE2,

6:07

S… Speaker 1 (Eemods 19.5 16_00)

IE3, and IE4.

6:08

S… Speaker 1 (Eemods 19.5 16_00)

We use code IE2,

6:10

S… Speaker 1 (Eemods 19.5 16_00)

it's high efficiency motor,

6:11

S… Speaker 1 (Eemods 19.5 16_00)

but now,

6:13

S… Speaker 1 (Eemods 19.5 16_00)

it's no longer,

6:14

S… Speaker 1 (Eemods 19.5 16_00)

it's a high efficiency motor.

6:15

S… Speaker 1 (Eemods 19.5 16_00)

Now,

6:16

S… Speaker 1 (Eemods 19.5 16_00)

in Korea, we cannot sell and buy IE2 motor.

6:19

S… Speaker 1 (Eemods 19.5 16_00)

So,

6:20

S… Speaker 1 (Eemods 19.5 16_00)

why I explain this?

6:24

S… Speaker 1 (Eemods 19.5 16_00)

I think later I will need to calculate how much electricity

6:28

S… Speaker 1 (Eemods 19.5 16_00)

we have saved.

6:29

S… Speaker 1 (Eemods 19.5 16_00)

But I had to add some reference efficiency.

6:33

S… Speaker 1 (Eemods 19.5 16_00)

But as you know,

6:34

S… Speaker 1 (Eemods 19.5 16_00)

each keratin motor and each motor have different

6:38

S… Speaker 1 (Eemods 19.5 16_00)

reference efficiency.

6:40

S… Speaker 1 (Eemods 19.5 16_00)

So later I need to make one DG.

6:43

S… Speaker 1 (Eemods 19.5 16_00)

So when before you have the IE3 and

6:47

S… Speaker 1 (Eemods 19.5 16_00)

the total motor is ready.

6:50

S… Speaker 1 (Eemods 19.5 16_00)

When I averaged all efficiency,

6:54

S… Speaker 1 (Eemods 19.5 16_00)

it was 92 .2.

6:57

S… Speaker 1 (Eemods 19.5 16_00)

But we need to think about it.

6:59

S… Speaker 1 (Eemods 19.5 16_00)

One kilowatt motor has 80

7:04

S… Speaker 1 (Eemods 19.5 16_00)

% of efficiency.

7:05

S… Speaker 1 (Eemods 19.5 16_00)

One hundred kilowatt motor has 90

7:10

S… Speaker 1 (Eemods 19.5 16_00)

% of efficiency.

7:11

S… Speaker 1 (Eemods 19.5 16_00)

It doesn't mean it has the same.

7:14

S… Speaker 1 (Eemods 19.5 16_00)

kind of saving energy efficiency.

7:17

S… Speaker 1 (Eemods 19.5 16_00)

So I had to get some kind of weighted

7:21

S… Speaker 1 (Eemods 19.5 16_00)

mean.

7:22

S… Speaker 1 (Eemods 19.5 16_00)

So if I get some weighted mean,

7:24

S… Speaker 1 (Eemods 19.5 16_00)

it would be 95 .5.

7:27

S… Speaker 1 (Eemods 19.5 16_00)

So I had to manage it like medium.

7:31

S… Speaker 1 (Eemods 19.5 16_00)

I need to get some balance value.

7:34

S… Speaker 1 (Eemods 19.5 16_00)

So I choose I2 is 92 % and

7:38

S… Speaker 1 (Eemods 19.5 16_00)

I3 is 94 % and I4 is 96%.

7:47

S… Speaker 1 (Eemods 19.5 16_00)

So from now on,

7:48

S… Speaker 1 (Eemods 19.5 16_00)

I want to introduce what we are going to do

7:52

S… Speaker 1 (Eemods 19.5 16_00)

from now on.

7:53

S… Speaker 1 (Eemods 19.5 16_00)

So change 1

7:57

S… Speaker 1 (Eemods 19.5 16_00)

is like IE3 will be IE4.

8:00

S… Speaker 1 (Eemods 19.5 16_00)

We need to raise the minimum

8:04

S… Speaker 1 (Eemods 19.5 16_00)

distance level.

8:18

S… Speaker 1 (Eemods 19.5 16_00)

1 ,000 volt below and then 2 ,4 ,6 volt and

8:23

S… Speaker 1 (Eemods 19.5 16_00)

then actually Korea government have

8:27

S… Speaker 1 (Eemods 19.5 16_00)

a plan to roll out from January 1st to

8:31

S… Speaker 1 (Eemods 19.5 16_00)

2027 but now

8:36

S… Speaker 1 (Eemods 19.5 16_00)

maybe just like it haven't distant yet

8:40

S… Speaker 1 (Eemods 19.5 16_00)

but maybe 6 months maybe fully

8:46

S… Speaker 1 (Eemods 19.5 16_00)

IFO is fully implemented by January

8:51

S… Speaker 1 (Eemods 19.5 16_00)

2013

8:55

S… Speaker 1 (Eemods 19.5 16_00)

and then variable speed consumption vocals

9:00

S… Speaker 1 (Eemods 19.5 16_00)

will be added.

9:01

S… Speaker 1 (Eemods 19.5 16_00)

So,

9:02

S… Speaker 1 (Eemods 19.5 16_00)

for the scope is like 0

9:07

S… Speaker 1 (Eemods 19.5 16_00)

.78 to 374 watts,

9:10

S… Speaker 1 (Eemods 19.5 16_00)

and IPEM is 600 to 6000 IPEM.

9:14

S… Speaker 1 (Eemods 19.5 16_00)

And this one will be notified January 2027,

9:21

S… Speaker 1 (Eemods 19.5 16_00)

and then with a 6 -month grid period,

9:25

S… Speaker 1 (Eemods 19.5 16_00)

and then will be effected 2000 July 1st.

9:29

S… Speaker 1 (Eemods 19.5 16_00)

And then we will be started by IE3.

9:32

S… Speaker 1 (Eemods 19.5 16_00)

9:39

S… Speaker 1 (Eemods 19.5 16_00)

as I explained to you,

9:41

S… Speaker 1 (Eemods 19.5 16_00)

in Korea when we started the math program,

9:44

S… Speaker 1 (Eemods 19.5 16_00)

the first step was to have started

9:48

S… Speaker 1 (Eemods 19.5 16_00)

first.

9:49

S… Speaker 1 (Eemods 19.5 16_00)

And then hopefully January,

9:52

S… Speaker 1 (Eemods 19.5 16_00)

I don't know,

9:53

S… Speaker 1 (Eemods 19.5 16_00)

in 2013,

9:55

S… Speaker 1 (Eemods 19.5 16_00)

January,

9:56

S… Speaker 1 (Eemods 19.5 16_00)

we will be done all.

10:00

S… Speaker 1 (Eemods 19.5 16_00)

across all sizes and

10:05

S… Speaker 1 (Eemods 19.5 16_00)

next variable

10:09

S… Speaker 1 (Eemods 19.5 16_00)

speed induction motor I already

10:14

S… Speaker 1 (Eemods 19.5 16_00)

explained what we will do but one thing is kind of only

10:19

S… Speaker 1 (Eemods 19.5 16_00)

operation will be included if

10:24

S… Speaker 1 (Eemods 19.5 16_00)

the motor has like dual supply

10:28

S… Speaker 1 (Eemods 19.5 16_00)

motors such as the motor has like

10:33

S… Speaker 1 (Eemods 19.5 16_00)

60 hertz 50 hertz

10:35

S… Speaker 1 (Eemods 19.5 16_00)

plus like 35Hz

10:40

S… Speaker 1 (Eemods 19.5 16_00)

operated.

10:40

S… Speaker 1 (Eemods 19.5 16_00)

In that case,

10:42

S… Speaker 1 (Eemods 19.5 16_00)

that motor will be included in the original mass.

10:45

S… Speaker 1 (Eemods 19.5 16_00)

But if that motor only operated at 35Hz,

10:50

S… Speaker 1 (Eemods 19.5 16_00)

it will be included in this variable speed induction motor

10:54

S… Speaker 1 (Eemods 19.5 16_00)

mass.

10:55

S… Speaker 1 (Eemods 19.5 16_00)

It's a bit different.

10:56

S… Speaker 1 (Eemods 19.5 16_00)

So,

10:59

S… Speaker 1 (Eemods 19.5 16_00)

as I told you,

11:01

S… Speaker 1 (Eemods 19.5 16_00)

variable speed induction motor,

11:03

S… Speaker 1 (Eemods 19.5 16_00)

I mean, I asked for variable speed induction motor.

11:06

S… Speaker 1 (Eemods 19.5 16_00)

is equal,

11:07

S… Speaker 1 (Eemods 19.5 16_00)

I mean, belongs to I3.

11:09

S… Speaker 1 (Eemods 19.5 16_00)

So efficiency is about,

11:12

S… Speaker 1 (Eemods 19.5 16_00)

for example,

11:13

S… Speaker 1 (Eemods 19.5 16_00)

0 .75 kW.

11:16

S… Speaker 1 (Eemods 19.5 16_00)

So 75 to 82 .5%.

11:21

S… Speaker 1 (Eemods 19.5 16_00)

And then bigger water,

11:23

S… Speaker 1 (Eemods 19.5 16_00)

like above 200 kW,

11:25

S… Speaker 1 (Eemods 19.5 16_00)

will be like 94 .46 to 96 .0.

11:30

S… Speaker 1 (Eemods 19.5 16_00)

It depends on the speed.

11:31

S… Speaker 1 (Eemods 19.5 16_00)

So far,

11:37

S… Speaker 1 (Eemods 19.5 16_00)

how much energy we have saved?

11:40

S… Speaker 1 (Eemods 19.5 16_00)

by, I mean,

11:42

S… Speaker 1 (Eemods 19.5 16_00)

the two,

11:44

S… Speaker 1 (Eemods 19.5 16_00)

I mean, the width at the maximum.

11:46

S… Speaker 1 (Eemods 19.5 16_00)

So I,

11:48

S… Speaker 1 (Eemods 19.5 16_00)

in Somia,

11:49

S… Speaker 1 (Eemods 19.5 16_00)

like, the physical capacity of the water is 25

11:54

S… Speaker 1 (Eemods 19.5 16_00)

gigawatt.

11:55

S… Speaker 1 (Eemods 19.5 16_00)

And then operating hours,

11:56

S… Speaker 1 (Eemods 19.5 16_00)

like, 6 ,000 hours.

11:58

S… Speaker 1 (Eemods 19.5 16_00)

And then low temperature is 27,

12:00

S… Speaker 1 (Eemods 19.5 16_00)

like 70%.

12:02

S… Speaker 1 (Eemods 19.5 16_00)

And then,

12:03

S… Speaker 1 (Eemods 19.5 16_00)

effective output is,

12:05

S… Speaker 1 (Eemods 19.5 16_00)

like, 105 kilowatt hour

12:09

S… Speaker 1 (Eemods 19.5 16_00)

a year.

12:10

S… Speaker 1 (Eemods 19.5 16_00)

And I told you,

12:12

S… Speaker 1 (Eemods 19.5 16_00)

like,

12:12

S… Speaker 1 (Eemods 19.5 16_00)

When I made a difference,

12:14

S… Speaker 1 (Eemods 19.5 16_00)

IE2 is 0 .92 and IE3 is 0

12:18

S… Speaker 1 (Eemods 19.5 16_00)

.94 and IE4 is 0 .96

12:22

S… Speaker 1 (Eemods 19.5 16_00)

and electricity price

12:26

S… Speaker 1 (Eemods 19.5 16_00)

is like 76 .63

12:30

S… Speaker 1 (Eemods 19.5 16_00)

per hour and

12:34

S… Speaker 1 (Eemods 19.5 16_00)

motor lifetime will

12:39

S… Speaker 1 (Eemods 19.5 16_00)

be like I said 15 years.

12:47

S… Speaker 1 (Eemods 19.5 16_00)

This calculation,

12:47

S… Speaker 1 (Eemods 19.5 16_00)

when the motor is changed from I2 to

12:51

S… Speaker 1 (Eemods 19.5 16_00)

I3,

12:52

S… Speaker 1 (Eemods 19.5 16_00)

2 .43TW

12:56

S… Speaker 1 (Eemods 19.5 16_00)

per year will be saved.

12:59

S… Speaker 1 (Eemods 19.5 16_00)

And from I3 to I4,

13:01

S… Speaker 1 (Eemods 19.5 16_00)

2 .33TW per year will be saved.

13:05

S… Speaker 1 (Eemods 19.5 16_00)

And from I2 to I4,

13:08

S… Speaker 1 (Eemods 19.5 16_00)

to change it,

13:11

S… Speaker 1 (Eemods 19.5 16_00)

4 .76TW per year will be changed.

13:17

S… Speaker 1 (Eemods 19.5 16_00)

I had to double check.

13:19

S… Speaker 1 (Eemods 19.5 16_00)

The government said when it changed

13:23

S… Speaker 1 (Eemods 19.5 16_00)

from I2 and I3,

13:25

S… Speaker 1 (Eemods 19.5 16_00)

the government said we have saved the money a year

13:30

S… Speaker 1 (Eemods 19.5 16_00)

like 174 .4

13:37

S… Speaker 1 (Eemods 19.5 16_00)

billion a year.

13:40

S… Speaker 1 (Eemods 19.5 16_00)

When I divide it to the dollar.

13:44

S… Speaker 1 (Eemods 19.5 16_00)

76 .341kWh.

13:48

S… Speaker 1 (Eemods 19.5 16_00)

We can save electricity

13:52

S… Speaker 1 (Eemods 19.5 16_00)

2 .32kWh here.

13:55

S… Speaker 1 (Eemods 19.5 16_00)

I said 2 .43kWh

14:01

S… Speaker 1 (Eemods 19.5 16_00)

and the government said 2 .32kWh.

14:03

S… Speaker 1 (Eemods 19.5 16_00)

It's similar.

14:04

S… Speaker 1 (Eemods 19.5 16_00)

So I can save

14:08

S… Speaker 1 (Eemods 19.5 16_00)

this amount of money.

14:14

S… Speaker 1 (Eemods 19.5 16_00)

So annual saving result,

14:15

S… Speaker 1 (Eemods 19.5 16_00)

from 2008,

14:17

S… Speaker 1 (Eemods 19.5 16_00)

the Korean government was secured in I2.

14:19

S… Speaker 1 (Eemods 19.5 16_00)

So first,

14:21

S… Speaker 1 (Eemods 19.5 16_00)

we didn't have the saving of,

14:24

S… Speaker 1 (Eemods 19.5 16_00)

you know,

14:25

S… Speaker 1 (Eemods 19.5 16_00)

for 15 years.

14:27

S… Speaker 1 (Eemods 19.5 16_00)

Like,

14:28

S… Speaker 1 (Eemods 19.5 16_00)

we have saved like 23 .2 terawatt.

14:33

S… Speaker 1 (Eemods 19.5 16_00)

14:37

S… Speaker 1 (Eemods 19.5 16_00)

.2 terawatt.

14:39

S… Speaker 1 (Eemods 19.5 16_00)

And then,

14:40

S… Speaker 1 (Eemods 19.5 16_00)

I think,

14:40

S… Speaker 1 (Eemods 19.5 16_00)

2023.

14:44

S… Speaker 1 (Eemods 19.5 16_00)

like IE3 will be kind of all in

14:49

S… Speaker 1 (Eemods 19.5 16_00)

the market like all kind of work the motor is setting

14:53

S… Speaker 1 (Eemods 19.5 16_00)

up so it takes time to 15 years this is

15:01

S… Speaker 1 (Eemods 19.5 16_00)

a tutorial and for instance like

15:06

S… Speaker 1 (Eemods 19.5 16_00)

two things one for 15 years

15:10

S… Speaker 1 (Eemods 19.5 16_00)

due to like a mess program

15:14

S… Speaker 1 (Eemods 19.5 16_00)

Korean government and Korean market have saved a lot of electricity and

15:20

S… Speaker 1 (Eemods 19.5 16_00)

then

15:21

S… Speaker 1 (Eemods 19.5 16_00)

But from now on,

15:22

S… Speaker 1 (Eemods 19.5 16_00)

with the IE4 program and then the motor

15:27

S… Speaker 1 (Eemods 19.5 16_00)

driving,

15:31

S… Speaker 1 (Eemods 19.5 16_00)

with SD motor also can save

15:35

S… Speaker 1 (Eemods 19.5 16_00)

a lot of electricity in Korea.
