From July, a new Visualization tool that shows the amount of electricity used and simplifying^*3 changing contract amperage services will be provided in turn^*4 for customers in all service areas^*5 who have Smart Meter installed.

TEPCO's entire service area has approximately 2.2 million Smart Meters installed (as of June 20, 2015). We aim to speed up installations so that all customers can use Smart Meter services sooner and have all installations for customers completed by 2020 (approx. 27 million) of which approx. 10 million are to be installed by 2016.
