About this data
Monthly electricity supplied to customers in Japan by retail electricity suppliers, by voltage class: extra-high voltage (large factories), high voltage (offices, mid-sized plants) and low voltage (households and shops), with low voltage split into regulated transitional tariffs and liberalised tariffs, in MWh. Monthly data since April 2016, when the survey was reorganised after full liberalisation of electricity retail.
