'계시별 요금제'는 하계·동계·춘추계의 계절별과 경부하·중간 부하·최대부하의 시간대별로 구분하여 전기요금을 차등 적용하는 것을 말한다. 수요관리 및 소비자 선택권 확대 목적으로 미국·영국·프랑스 등 주요국에서 주택용 전기요금의 하나로 시행 주이다. 그러나 국내에서는 산업용, 일반용 소비자에게는 계시별 요금제를 적용 중이지만, 아직까지 주택용 전기요금에는 계시제가 도입되지 않은 상태이다. 하지만 정부가 현재 시행중인 전기요금 누진제도의 대안으로 계절과 시간대에 따라 요금을 부과하는 '계시별 요금제' 도입을 추진할 예정이다. 이는 소비자의 합리적인 전기 소비를 유도해 각 가정의 전기료 부담을 줄이고, 누진제 완화로 악하된 한국전력공사의 재정 부담도 줄이겠다는 취지이다. 그러나 신 요금제 도입에 따른 전기료 인상 논란 여기 이어질 전망이다. 따라서 본 연구에서는 첫째 현행 '누진제 요금제'와 새로 도입될 '계시별 요금제'에 따른 소비자 전기요금의 변화에 대해 살펴보고, 둘째 가정용 ESS 도입에 따른 전기료 절감에 대하여 검토한 후, 마지막으로 계시별 요금제 도입에 따른 효율적인 ESS 도입 및 운영과 시범 적용 예정인 계시별 요금제에 대한 개선 방향에 대하여 간략히 살펴보고자 한다.

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.

This study analyzes the effect of the 2^nd pilot test of Tiime of Use (TOU) pricing for Korean households using a two-level electricity demand model. The test, implemented from May to September 2021, was conducted to compare the effects of two TOU pricing rates and the standard rates for households living in apartment and detached house in 7 provinces of Korea. Based on the data on electricity consumption during the test period and during the same period last year of the 1,292 participants and their socio-economic characteristics, this study analyzes (1) whether the relative demand across periods has changed in response to hourly price changes and (2) whether the price responsiveness of daily consumption has changed after the introduction of TOU pricing. The results show that both types of TOU pricing affect neither the relative demand across periods nor the price responsiveness of daily consumption. The reason behind the results could be related to the level of TOU pricing rates and the periodical classification, which were not sufficient to induce changes in the participants' electricity demand patterns.

Currently, the domestic electricity rates for houses are charged by applying a progressive level according to monthly electricity usage. Electricity rates rise sharply wWhen the amount of electricity used is large, electricity rates rise sharply. The standardized electricity rate progressive system has limitations in that it lacks consideration of the consumers' power usage patterns and limits consumers' their options. Accordingly, the Ministry of Trade, Industry and Energy and the Korea Electric Power Corporation have been demonstrating the basis of a rate system for housing, which is a method of charging electricity according to the amount of electricity used by season and time. In this paper, 10 electricity usage patterns were derived through from AMI data analysis for 5 five years of 362 apartment complexes located in metropolitan cities. The patterns were, and then applied to the existing domestic electricity rate and time-by-time rates applied to demonstrations, and by time-by-time rates in the US and Australia. The effect of the optional rate by pattern was compared and analyzed. As a result, it was confirmed that benefits occurred in five5 patterns compared to existing rate plans, and the electricity rates increased in 5 five patterns, and t. This phenomenon shows the same phenomenon withis the same as the overseas rates, including domestic rates being demonstrated.
