한국형 가스복합발전소의 건설 및 운영에 따른 경제적 파급효과 분석

This study quantitatively analyzes the effects of constructing and operating a liquefied natural gas (LNG) combined cycle power plant(CCPP) using Korean gas turbines on our economy. The importance of LNG CCPP is increasing day by day in accordance with energy transition policies and carbon neutrality, and in fact, the demand for new plants is expected to be large for a considerable period of time in the future. However, gas turbines, which play the most important role in LNG CCPPs, are mainly dependent on foreign products, so there is a great need for domestic technology development. Korea has a goal of developing domestic gas turbine technology and increasing its share in the global market as well as in the domestic market. This paper is the first attempt to quantitatively analyze the effects for constructing and operating a LNG CCPP using domestically produced gas turbines on our economy. According to the analysis results, the production-inducing effect of the construction sector is about 1.3 trillion won, the value-added creation effect is 482.1 billion won, the employment-inducing effect is 5,061 people, and the wage-inducing effect is 232 billion won. On the other hand, the production-inducing effect of the operation sector is about 312 billion won per year, the value-added creation effect is 130.2 billion won/year, the employment-inducing effect is 1,173 people/year, and the wage-inducing effect is 58.6 billion won. These results imply that producing gas turbines instead of importing them from a foreign country can have a positive impact on the economy. Furthermore, if the efficiency of gas turbines increases through technological development in the future, the ripple effect of the operation sector is expected to increase.
