Apple II -> Year 1977
My First personal Computer, year 1985!!!
Question!
How many times bigger?
USD 1 = KRW 1150
USD 214= KRW 247,000

Electric Power & Tariff
How much of electric power to be
consumed if this computer is
‘power on’ for one whole month?
150W x 24Hour x 30Days
= 108,000Wh
= 108kWh

Korea Nuclear Power Plants (Kori)
One Nuclear Power Plant Capacity
1GW = 1,000MW = 1,000,000kW

Photovoltaic
East Sun Power Gen. Co.
-24MW, 0.7Mil m2 , US
200Mil.
1 Nuclear Power Plant =>
1GW = 1000MW
24MW x 40 approx.
1000MW
Capacity : to be equivalent to 1 Nuclear Power Plant (x 40 times)
-> 28 Mil m2 , US 8,000 Mil. (US 8 Bil.)
Power Generation: to be equivalent to 1 Nuclear Power Plant (x 5
times)
(with capacity factor of 20%, tracking device)
-> 140 Mil. m2 , US 40 Bil.
** Still we don’t get power during the night, rainy days,…
Technical Advancements (ex: Wind)

Q: Is hydropower to
be included in this
merit order?
Q: Is Hourly load
always to be
vertical? What if it
is not?

Economics of Smart Grid (Demand Response)
- the need to have a framework to facilitate the Demand Response in power market
- the Importance of the bilateral information exchange
