Home View data published by RTE {{item}} {{item.label}} Schedule of Tempo-type supply offerings {{vm.currentItem}}

Tempo-type electricity supply offerings comprise different price levels, variable according to the time and day of the year.

  • Red days correspond to periods of the year with high consumption,
  • White days to an intermediate level,
  • Blue days to those with the lowest consumption.

Each supplier providing this type of offering applies its own price to the different types of day. Every day, RTE publishes the colour of the following day, which applies to all consumers having chosen a Tempo-type supply offering, irrespective of their supplier.
 

In the event of publication problems, please feel free to call the RTE hotline.

In accordance with the Deliberation by the French Energy Regulatory Commission of 30 October 2014 ruling on the roles of electricity network managers relating to Tempo-type peak load reduction tariffs, the only reference information relating to the colour of Tempo-type days that is binding on RTE is that published on D-1 at 10.30 am, on this page. When the information available to RTE permits, RTE broadcasts a preliminary signal purely for information purposes between 8.00 and 10.30 am. The pre-signalled information does not constitute the definitive information and is not binding on RTE. Except for the colour of the next day published at 10.30 am, the other information available on this page is provided purely for information purposes by RTE, which cannot be held responsible for any use that may be made of this data.

In accordance with the Deliberation by the French Energy Regulatory Commission of 15 July 2015 ruling on the roles of electricity network managers relating to Tempo-type peak load reduction tariffs, RTE provides interested parties with a technical note explaining the functioning of the algorithm used to determine the colour of Tempo days, together with a description of a simplified version of this algorithm.

Method for choosing Tempo days

RTE also allows suppliers who so wish to invoke Tempo days according to their own scenarios. The technical and operational methods of transmitting scenarios between suppliers and RTE are specified in the note below :
