Abstract

Current residential electricity rates, which are charged regardless of consumption patterns, have a problem of restricting consumer choice. In order to improve the problem, the Korea government started a demonstration project based on Time-Of-Use(TOU) pricing from September 2019. However, the analysis of its effect is still limited. This study analyzed the changes and limitations of TOU pricing compared to the current progressive pricing. The result showed that the high rate payer's bill decreased by up to 33.8 % while the low rate payer's bill increased by up to 117.7 %. This can lead to the problem of accepting electricity rates from a social point of view. In this study, TOU pricing based on progressive pricing was proposed to overcome the problem. The results presented the rate changes depending on the power consumption patterns while decreasing the average rate change from 32 % to -1.9 %. It means that the proposed pricing can support the TOU effect while maintaining the framework of the existing progressive pricing.

소비패턴과 무관하게 부과되는 현행 주택용 전기요금은 소비자선택권을 제약하는 문제가 있다. 이의 개선을 위하여 정부는 2019년 9월부터 주택용 계시별 요금제 기반의 실증 사업을 개시하였으나 그 효과에 대한 분석은 아직 제한적이다. 본 연구에서는 우선 기존 누진요금 대비 주택용 계시별 요금의 변화와 한계를 분석하였다. 분석을 위하여 두 개 단지의 아파트 전기사용량 데이터를 사용하였다. 주택용 계시별 요금제 적용 결과 전기사용량이 많은 경우 요금이 최대 33.8 % 까지 감소하는 반면 전기사용량이 적은경우 최대 117.7 % 증가한 것으로 나타났다, 이는 사회적 관점에서 전기요금의 수용성 문제를 야기할 수 있다. 이를 극복하기 위하여 본 연구에서는 누진제기반 계시별요금제를 제시하였다. 분석 결과 누진제 대비 계시별 요금제는 사용자의 전력소비 패턴에 따라 요금의 변동을 보이면서도 요금변동률 평균은 32%에서 -1.9 %로 감소한 것으로 나타났다. 이는 제안된 전기요금이 기존 누진제의 틀을 유지하면서도 계시별요금제의 효과를 지원할 수 있음을 의미한다.
