World : Growing a Smart Grid By the Millions in Tokyo

TEPCO and Landis+Gyr are proving that large-scale and fast-moving smart grid deployments are possible.

Japan is well-known for being early adopters of technology of all kinds, and that’s no different when it comes to the Internet of Things (IoT). Tokyo Electric Power (TEPCO) and Landis+Gyr have announced that their collaboration on modernizing Tokyo’s electric grid has now grown to more than 10 million advanced meters and devices.

For the utility industry, the size of this IoT grid is impressive, to say the least. TEPCO and Landis+Gyr are collaborating to install an average of 1 million smart meters and other devices every three months, which means the ultimate goal of 30 million devices in the next seven years is well within reach.

TEPCO is Japan’s largest electric utility company, and the fourth largest in the world. It provides service to 45 million people—roughly one-third of the country’s total population. That area includes the ultra-dense Tokyo, which creates both difficulties and efficiencies for deploying these smart devices.

Right now, the network is moving data at a rate of 513 million interval reads daily, and that’s set to grow to more than 1.3 billion interval data packets daily once the network is complete in the next few years. That equates to quite a challenge, not only in keeping the network active, but also in managing and making insights from the data.

Hiroshi Yamaguchi, an executive vice president at TEPCO, said in a statement: “Our deployment is making smooth progress, and reaching the 10 million endpoints on the network milestone is a clear indication of the efficiency of our program and the capability of our leading-edge system developed by Landis+Gyr.”
