Where does Tokyo get its electricity?

Written by Editorial Team | Last Updated: August 2026

Tokyo receives its primary electricity supply through generation facilities operated predominantly by Tokyo Electric Power Company (TEPCO), supplemented by energy procured through the wider national power grid interconnectors. Because the dense metropolitan area consumes immense amounts of power while hosting limited local generation capacity, its electricity is transmitted from large-scale thermal power plants fueled by liquefied natural gas and coal, nuclear facilities situated outside the immediate prefecture when operational, and a growing mix of regional hydroelectric and renewable energy installations located across neighboring Japanese regions.
