“Power-saving with Flet’s!”
Cloud-type electric power-related data “visualizing” service
Provision of “Flet’s Eco-megane”

Nippon Telegraph and Telephone West Corporation (hereinafter “NTT West”) (Head office: Osaka City, Osaka, President: Shinichi Otake) will start providing households with an electric power-related data “visualizing” service called “Flet’s Eco-megane” (hereinafter “this service”) from July 17, 2012.

1. Background and purposes
NTT West has made efforts to reduce environmental loads through the provision of services using ICTs in preparation for the realization of a low-carbon society. We have offered a solution for “Visualizing energy-related data for corporations” as a service for corporations, and the Photovoltaic Power Generation Monitoring Service for households by establishing NTT Smile Energy Inc.* 1 in June 2011. At the same time, with increased public awareness towards power-saving due to power shortages and requests for power-saving following the Great East Japan Earthquake, effective and sustainable efforts for power-saving have become increasingly important.
Based on this background, focusing on the viewpoint that “the power-saving effect in households per day of ‘visualizing’ electric power-related data is approximately 10%,” * 2 NTT West will start providing this service from July 17, 2012, thus contributing to power-saving and the reduction of CO2 emissions by “visualizing” household power consumption.
Under the “Entire Home Digitalization (ie-digi) Concept, * 3” which is intended to deliver a convenient and comfortable lifestyle to everyone, NTT West aims through this service to realize a smart lifestyle with “ie-digi” by promoting power-saving at home.

* 1: NTT Smile Energy Inc. (Head office: Osaka City, Osaka, President: Hiroaki Taniguchi) was established on June 1, 2011 as a joint venture between NTT West and OMRON Corporation. Using the two companies’ strengths and expertise, such as NTT West’s network technologies and OMRON’s advanced sensing and control technologies, and by integrating communications and control, NTT Smile Energy provides services to promote support for energy-generation & energy-saving as well as renewable energy use.
* 2: Data provided by the Energy Conservation Center, Japan (in Japanese)
* 3: This is an effort advocated by NTT West to create a new lifestyle by networking all digital equipment in a house, and further networking the house with other houses. For further information, please access the following “website for Digital House.” (in Japanese)

2. Outline of “Flet’s Eco-megane”
This is a cloud-type electric power-related data “visualizing” service designed to support power-saving at home through the visualization of the home’s electricity status.
By connecting the “Electric Power Measurement Sensor” mounted on the distribution board in their home to the Internet, users can confirm their power consumption and electricity bills via their personal computer, smartphone, or tablet device.
The main features of this service are as follows:

(1) Cloud-type electric power-related data “visualizing” service
<1> Since this is a cloud-type service, your household power consumption and electricity bills can be confirmed anytime and from anywhere—at home or from outside the home such as at your work place, via a personal computer, smartphone, or tablet device.
<2> Since electric bills are calculated on the cloud server side, this service can be made to match each power company’s price plan and monthly fluctuating electricity charges.* 4
<3> Since the server has weather and temperature information for every region, users can save electric power efficiently by viewing the information along with the data of their electricity bills and power consumption.
<4> Upgrading the version at the server allows users to use new services even if they are unaware of that particular application version upgrade.
(2) Comparison of electric power situations between users
Since this service allows users to compare their power consumption and electricity bills with those of other households that use this service (the average value of households on a similar power purchase agreement), users can understand their own levels of power consumption and set new power-saving targets.
(3) Function of displaying estimated electricity bills at the end of the month
An estimate of the electricity bill at the end of the month will be calculated and displayed.
(4) Introduction of ideas for power-saving
Content will be prepared that introduces power-saving ideas, etc.

* 4: Rough estimates of electric bills are calculated based on each power company’s power purchase agreement. However, the estimates will show figures that differ from the actual charges from the power company, because different measurement methods and periods will be used for the calculations.
