Agency for Natural Resources and EnergyA Report from the Smart Meter System Planning Conference Security Review Working Group was Compiled

From February 2015, the Ministry of Economy, Trade and Industry (METI) hosted meetings for the Smart Meter System Planning Conference Security Review Working Group and has compiled a report. In the report, a concrete framework is suggested for strengthening the security of smart meters, whose full-fledged introduction will be promoted in Japan.

Background and objective

Smart meters are a new kind of watt-hour meter, which have communication functions and enables remote meter-reading and operations for starting and stopping the electricity supply. The full liberalization of the retail electricity business, which is to be implemented in April 2016, will allow consumers to choose from various service plans and electric power companies. Accordingly, smart meters are regarded as an essential part of the infrastructure that will support an increase in customer options.

In the Strategic Energy Plan, which was compiled in April 2014, it is stipulated that “Smart meters will have been installed in all households and businesses by the early 2020s.” In the future, the full-fledged installation of smart meters in households and other places will be conducted. The installations will be complete in Tokyo Electric Power Company’s service area by the end of FY 2020, and nationwide in Japan by the end of FY 2024.

On the other hand, with remote meter-reading and operations for starting and stopping the electricity supply enabled by the communication functions as a result of the introduction of smart meters, there may be risks of disturbances in the stable supply of electricity (possibility of large-scale power outages), information leakage, and other incidents due to cyberattacks and other security-related issues.

Fundamentally, each electric power company should independently and continuously implement upgrades for security measures for smart meters in a responsible manner. However, it is necessary to strengthen security measures for smart meters in order to secure a certain level of measures because the success of the electric power system reform depends on the results of the security measures, and also because planning for ensuring security measures is part of the foundation for supporting Japan’s growth strategy.

Therefore, METI established the Smart Meter System Planning Conference Security Review Working Group and compiled a concrete outline for trying to strengthen security.
