Introduction to Power Generation
The main purpose of this power generation business is
to produce electricity and supply it safely and conveniently to end-users.
Currently, SK E&S operates its Gwangyang LNG Power Plant and Paju LNG Power Plant,
and Hanam CHP(Combined Heat and Power) and Wirye CHP.
Classification by Power Generation Method
Thermal power generation
Coal, oil, LNG, LNG combined,
coal gasification combined
Renewable energy generation
Wind, solar, tidal power,
geothermal heat, fuel cells
Nuclear power generation
Nuclear fission to produce electricity
Hydro-electric, pumped, small hydro
What is LNG Combined Power Generation?
LNG combined power generation consists of primary and secondary power generation. Primary power generation is derived from the heat generated from the combustion of natural gas in the gas turbine. Secondary power generation is derived from the operation of a steam turbine using high-temperature exhaust gases as sources of heat to produce high-temperature and high-pressure steam.
Advantages of the LNG Combined Power Generation
More efficient than ordinary
thermal power generation
Combined power plant generation efficiency : 57%
Ordinary power plant generation efficiency : 38~40%
Almost no pollutants emitted, as LNG,
a clean fuel, is used
Can be used near large cities
Short Construction Period
Compared to other power plants,
the construction period is short
Nuclear power : 65 months,
Coal : 50 months,
LNG combined : 30 months
