Japanese utilities must install smart meters in all households by March 2025 to improve energy efficiency, according to the Ministry of Economy, Trade and Industry.
The legislation comes as the country faces a tighter electricity supply due to the meltdown of the 2011 Fukushima No 1 nuclear plant.
In a draft energy policy, the government said it expects the 10 regional utilities to install smart meters in every home and company by the early 2020s to encourage customers to save power by monitoring their usage in real time.
The utilities had originally set a deadline of 2032 but have pulled this forward to March 2025 in response to government calls.
The Tokyo Electric Power Company (TEPCO) is deploying 27 million smart meters as part of a citywide energy management platform.
Partnering with Toshiba and Landis+Gyr, the utility is breaking new ground with its latest generation AMI technology that addresses interoperability gaps, has an integrated standards-based security system and is fully scaleable.
The city is seen as an example for other Asian cities rolling out smart metering and grid technologies.
