Electricity sales trends and operational levels of nuclear power plants in Japan

Keywords: Nuclear Power 

The massive earthquake that hit Japan on March 11, 2011 caused tremendous damage. The earthquake and subsequent tsunami triggered a serious nuclear accident at the Fukushima No. 1 nuclear power plant owned by Tokyo Electric Power Co. (TEPCO), and these events also spurred a review of nuclear power in Japan. In this context, JFS provided data and information on power utilities and municipalities that have nuclear power plants, as well as trends in nuclear power policy at the government level in Japan.

Since 2011 JFS provided two graphs, updated at the end of every month, showing electricity demand for each of the ten major power utilities in Japan and operational levels of nuclear power plants across the country.

Electricity Sales Trends and Nuclear Plants Operational Levels (Final update: April 29, 2016)

The top-left graph below shows electricity sales trends of the 10 power utilities compared to 2010 levels. The bottom-left graph shows the operational levels of nuclear power plants across Japan. The graphs on the right show monthly electricity sales of the 10 power utilities. (Click to expand images.)

At the start of the complete deregulation of the retail electricity market in Japan in April 2016, the Federation of Electric Power Companies of Japan (FEPC) stopped providing the data covered in these graphs. Accordingly, this is the final update of this page.
