In these days global energy policy is changed from "supply" to "demand". In this regards, there are needs to analysis on effect of policy such as energy efficiency strategy, electricity rates. This study examines the relationship between energy consumption reduced by new energy policy and GDP growth for each industrial sector for Korea from 1970 to 2013. With respect to the direction of causality, energy use of 1th industry like agriculture and mining leads to GDP growth. On the other hand, GDP growth of 2nd industry, manufacturing, leads to energy use. And there is bidirectional causality in 3rd industry, service sector. These findings imply that the government policies aimed at reducing electricity consumptions and increasing energy efficiency should be progressed cautiously depend on status of each industry condition.

본 논문에서는 산업연관분석을 이용하여 한국과 일본 전력산업의 국민경제적 파급효과를 분석하고자 한다. 먼저 수요유도형 모형을 이용하여 생산유발효과, 부가가치 유발효과를 살펴본다. 아울러 공급유도형 모형 및 레온티에프 가격모형을 적용하여 전력산업의 공급지장효과와 물가파급효과에 대하여 한국과 일본을 비교 분석한다. 이러한 분석은 전력산업을 외생화하여 이루어지게 된다. 분석결과 전력산업에서의 1원(엔) 생산이 타 산업에 유발하는 생산유발효과는 한국 0.5946원, 일본 0.5446엔 이었으며, 타 산업에 유발하는 부가가치 유발효과는 한국 0.1716원, 일본 0.2929엔이었다. 전력산업의 공급지장효과는 한국 1.5932원, 일본 1.2801엔이었으며, 전력산업의 10% 가격 인상으로 인한 물가파급효과는 한국 0.2113%, 일본 0.2196%로 한국이 높게 나타났다.

Now Korea depends upon the imported resources for about 97% of total using energy. So from October, 2001 Korean government has supported renewable energy business owners by providing them with Electric Power Industry Basis Fund. Only plant-use electricity of the small hydro power plant is exactly managed, but other renewable energy plants is unprepared or not yet managed. Therefore, in this paper, we'll analyze the plant-use electricity management of the small hydro power and propose improvement plans for plant-use electricity of the photovoltaic power plant.

우리나라 제조업 부문의 상대적 전력투입비율은 OECD 국가들에 비해 높은 편이며 이는 전력가격이 OECD 평균보다 상대적으로 낮은 데에 기인한다. 또한 전력부문은 한국에서 온실가스 배출의 상당한 비중을 점유하고 있는데, 2018년 기준으로 전력생산의 투입연료로 석탄과 천연가스가 41.9%와 26.8%를 차지하기 때문이다. 따라서 우리나라 제조 부문에서 전력가격을 인상할 필요가 있으나 중소기업이 대기업보다 상대적으로 더 많은 영향을 받을 것이라는 우려가 있다. 본 연구는 시간가변적 파라메터 모형인 Kalman Filter 추정법을 이용하여 철강산업에서 대기업과 중소기업 전력수요의 가격 탄력성과 산출 탄력성을 추정하였다. 분석 결과, 기업의 크기에 상관없이 산출량 변화가 가격변화보다 전력수요에 더 많은 영향을 미치는 것으로 나타났다. 또한 대기업에서 전력수요에 대한 가격탄력성뿐만 아니라 산출탄력성의 분산이 중소기업보다 더 큰 것으로 추정되었다. 정책적 함의는 철강산업과 같은 에너지다소비 업종에서 어떻게 전력수요를 감축할 것인지에 관련되어 있다.

The electric power industry has played an important role in dramatic economic development in Korea and the electricity has constituted a critical factor sustaining the well-being of the Korean people. This study uses input-output analysis to investigate the role of four electric power sectors (hydroelectric, fossil-fuels, nuclear and non-utility) in the Korean national economy for the period 1985~1998, focusing on four topics: the impacts of electricity supply investments, the electricity supply shortage effects, and the impacts of the rise in electricity rates, and the inter-industry linkage effect. The overall results reveal that non-utility electric sector is superior in terms of the national economy-wide effects to other three sectors throughout the period. Finally, potential uses of the results are illustrated from the perspective of policy instruments and some policy implications are discussed.

This study compares the characteristics and the determinants of household electricity consumption for low electricity consuming and high electricity consuming households. The data are drawn from a household energy consumption sample survey by Korea Energy Economics Institute in 2015. The results show the differences in socio-demographic, dwelling, and electricity consumption characteristics between two households. Next, the factors affecting the household's electricity consumption are investigated. Common factor affecting the electricity consumption function is only the number of electrical appliances. There are also the differences in major determinants of the household's electricity consumption functions for two households. The results of this study would be useful for understanding socio-demographic, dwelling, and electricity consumption characteristics of low electricity consuming and high electricity consuming households.

The purpose of this study is to assess key competencies, especially mathematical skills and communications skills, in order to find disaccord between industry and college in the field of automotive electricity on technical engineering education. For this study, an assessment sheet is consisted of nine questions items. Four questions items of them are to assess mathematical skills and five questions items of them are to assess communications skills. 134 copies returned assessment sheets are analyzed after data cleaning and it is concluded that disaccord between industry and college in the field of automotive electricity on technical engineering education is found.

The purpose of this study is to build promotive measures and to develop alternative policies of DG(Distributed Generation) by finding and analysing effects of four business environment factors related to DEPB(District Electricity Power Business) on boosting DG. In this study, four business environment factors, which are the electric power industry restructuring, electricity tariff and pricing structure, regulations for DEPB, and conflicts of stake-holding groups, are considered as independent variables. And promotion factors of DG including small CHP(Combined Heat and Power) generation, which is outcome of DEPB, are considered as dependent variables. But dependent variables including booming of new renewable energy generation due to green energy pricing incentives, the electric power industry restructuring, and electricity tariff and pricing policies were separatively considered. In this study, some policies were proposed reflecting research results of empirical demonstrative analysis, previous studies, overseas cases, etc.

영국은 1989년 Electricity Act의 발효를 시작으로 전력산업 구조개편을 시작하였다. 이후 Pool 체계를 구성하였으며 10여년의 운영을 거쳐 NETA 체계를 새롭게 구성하였다. 이후 스코틀랜드 전력시장을 통합한 BETTA 체계를 도입하여 영국 전체의 전력시장을 통합하였다. 본 논문에서는 이러한 영국의 전력시장 구조개편 과정을 분석하고 각 체계의 특성을 정리하였으며 이러한 구조개편 과정에서 얻을 수 있는 시사점을 도출하였다.

Korea Power Exchange has successfully performed the Long-term Electricity Demand Forecasting. Recently there is a lot of change in electricity industry sector; the national master-plan for green gas emission reducing, rise of smart-grid, and new trend of electricity consumption, and it is becoming painful challenging for demand forecasting. In new circumstance the demand forecasting is required more flexible and more accurate.
