Dataset

Description2021년 10월 서울시 연료원별 일별 전력거래량 자료입니다. * 개별 발전기의 전력거래량, 주소 등은 해당 사업자의 영업정보이므로 정보공개법(제9조)에 따라 제 3자에게 제공하지 않고 있습니다. *전력거래량은 한전 전력수급계약(PPA) 등 전력시장에 미등록한 발전기의 발전량은 포함하지 않습니다. 우리나라 총발전량은 “한국전력통계”(한전발간)의 공식 자료 참조하시기 바랍니다. * 거래량은 송전단 기준이며, 한전 전력수급계약(PPA)등은 포함하지 않아 서울의 전체 발전량을 의미하지 않음. 단위 : MWh
