Tempo Infos Couleur du Jour

Hello Watt

About this app

The Tempo Infos by Hello Watt application tells you the color of today and tomorrow as well as a widget to install on your home screen.

EDF’s Tempo option gives you advantageous electricity prices 343 days a year. For the remaining 22 days, reduce your electricity consumption during winter peaks.

As a reminder, the Tempo option offers different prices depending on the color of the day:

- Blue (300 days/year): you benefit from a very advantageous electricity price → 30% savings on the price of electricity (including tax) during Peak Hours; 40% savings on the price of electricity (including tax) during off-peak hours.

- White (43 days/year): white days are also advantageous → 10% savings on the price of electricity (including tax) during Peak Hours; 24% savings on the price of electricity (including tax) during off-peak hours.

- Red (22 days/year): Tempo red days are those where electricity is much more expensive. The price per kWh during Peak Hours is up to 3 times higher. However, it is 15% savings on the price of electricity (including tax) during off-peak hours.

During Peak Hours on red days, it is in your best interest to consume less electricity and use an alternative heating method.

In addition, the Tempo Infos by Hello Watt application provides you with a history of Tempo days.


You can also receive notifications to be alerted of Tempo red days.
