스마트그리드가 활성화되기 위해서는 전력소비자들이 스마트그리드를 쉽게 수용할 뿐만 아니라 지속적인 사용을 해줘야 한다. 스마트그리드가 실제 사용자들에게 외면당한다면 스마트그리드의 기대효과는 실현되기 어렵다. 본 연구는 기대충족이론을 중심으로 스마트그리드의 지속사용에 영향을 미치는 요인을 탐색하고 요인 간 관계를 통계적으로 검증하였다. 연구결과 기대충족이론의 핵심 변수인 기대충족, 지각된 유용성, 만족, 지속사용의도 간 관계가 모두 통계적으로 유의하였다. 그리고 스마트그리드 지속사용을 위해서는 스마트그리드 친환경성의 편익보다는 전기요금절감과 전력공급신뢰성의 편익을 강조하는 것이 효과적임을 확인하였다. 이에 스마트그리드 이용자를 대상으로 시행되는 교육 및 홍보에서는 전기요금절감과 전력공급신뢰성 편익이 보다 강조될 필요가 있으며, 궁극적으로 스마트그리드가 실제로 그러한 편익을 발생시키고 있음을 경험하게 하거나 인지시키는 노력이 중요할 것이다. 본 연구는 국내의 스마트그리드 실제 사용자를 대상으로 조사된 자료를 활용하여 선도적으로 스마트그리드 지속사용에 관한 요인을 검토하고 정책적 시사점을 제시한다는 점에서 그 의의가 있다.
In order to promote the smart grid deployment, it is necessary that electric consumers not only easily accept the smart grid products and services but also use it continuously. The active consumer participation is necessary to achieve the full potential of smart grid technologies and their associated benefits. In this study, we have investigated the factors which affect consumers' continuance usage based on Expected Confirmation Model, and verified the relationship between factors statistically. According to the empirical results, we find that the relationship between confirmation, perceived usefulness, satisfaction, continuance intention is statistically significant. And we also find that it is effective to emphasize the electricity saving and power supply reliability in order to encourage smart grid consumers' continuance usage. Therefore it is necessary that we pay attention to the benefit of electricity saving and power supply reliability in smart grid consumer education and public relations. Furthermore it would be important that government makes an effort to make consumers experience or understand the actual benefit of smart grids. This study is significant in terms of an initial analysis on the continual usage of smart grids with the survey data of domestic smart grid users.
