Summer FY 2019 Electricity Supply and Demand Results Compiled along with Winter FY2019 Electricity Supply and Demand Outlook and Related Measures

November 6, 2019

Agency for Natural Resources and Energy

On November 6, 2019, the Electricity and Gas Basic Policy Subcommittee under the Electricity and Gas Industry Committee of the Advisory Committee for Natural Resources and Energy (hereinafter referred to as the “subcommittee”) held a meeting and compiled a report based on the data on electricity supply and demand for the summer of FY2019 as well as data on the outlook and measures for electricity supply and demand for the winter of FY2019.

Based on the compiled results, in terms of electricity supply and demand for the winter of FY2019, a reserve margin of 3%, which is the minimum ratio required for stable supply of electricity across Japan, is expected to be secured. However, the Ministry of Economy, Trade and Industry (METI) requests cooperation from the public in maintaining reasonable levels of energy-saving and energy conservation efforts as usual in recent years.

1. Background and purpose

Aiming to provide full-fledged electricity supply-demand measures to address Japan’s circumstances surrounding electricity after the Great East Japan Earthquake, Japan has been studying summer and winter electricity supply and demand as these are the seasons when electricity demand increases across Japan.

On November 6, 2019, the subcommittee held a meeting and compiled their report based on the data on electricity supply and demand for the summer of FY2019 as well as data on the outlook and measures for electricity supply and demand for the winter of FY2019.

2. Key points of the results of the electricity supply and demand for the summer of FY2019

  1. For the Tokyo, Chubu, Chugoku and Kyushu service areas, in early September of 2019, the reserve margin decreased due to an increase in demand caused by a nationwide rise in temperature as a result of the influence of Typhoon No. 15. However, the supply capacity did not fall below the reserve margin of 3%, the minimum ratio required for stable supply of electricity across Japan, thanks to the electricity interchange from other service areas.
  2. Concerning the results of the electricity supply and demand for the summer of FY2019 in other service areas, the reserve margin of 3%, the minimum ratio required for stable supply of electricity across Japan, was maintained.

3. Key points of the outlook and measures for electricity supply and demand for the winter of FY2019

  1. Concerning the outlook and measures for electricity supply and demand for the winter of FY2019, the reserve margin of 3%, the minimum ratio required for stable supply of electricity across Japan, is expected to be secured.
  2. Based on this expectation, the subcommittee decided to not request cooperation from the public in energy saving efforts with any numerical goal this winter. However, METI still requests cooperation from the public in maintaining reasonable levels of energy-saving and energy conservation efforts as usual in recent years.
