+ RTE is aware of the contribution of power quality to the performance of your site and is committed to the continuity and quality of electricity.


  • Consumers

  • Distributors

Our commitments in terms of power supply continuity

Under the terms of your CART (transmission grid access contract), RTE is committed to a maximum number of long outages (> 3 minutes) and short outages (from 1 second to 3 minutes).  The level of commitment is reviewed every three years and may be improved so that the client can benefit from these improvements.

For consumers, RTE is also committed to a cumulative maximum duration of long outages, with a threshold dependent on the site’s supply structure (the commitment is better if the site has several power feeds).

If very long outages occur due to an issue arising on the transmission system, RTE shall cover the cost of any penalties paid by distributors to their clients.

Our commitments in terms of voltage waveform quality

RTE undertakes to limit:

  • voltage amplitude variations (within a range around the declared supply voltage, according to the connection voltage),

  • rapid voltage fluctuations (Plt < 1),

  • voltage unbalance (rate < 2%),

  • frequency variations (50 Hz +/- 1% in interconnected system).

RTE also gives indicative harmonic values and undertakes to find a suitable solution if any issues arise.

RTE provides you with support and information

  • You will receive factual information concerning your power outages within 1 to 3 business days,

  • RTE shall reply within 2 weeks to any request for additional information regarding the analysis of a long outage,

  • RTE shall inform you when a commitment threshold is exceeded.

In the event that RTE does not meet its commitments, you may request compensation for the damage incurred by the incident (and, for distributors, a claim for compensation paid to your clients).

Information on outages and the associated commitments are also accessible via the Personalised Customer Area.

How to benefit from these commitments

These commitments to the quality of power supply are included in your consumer or distributor CART. To allow us to best provide you with these services, you will need:

  • to allow RTE to undertake maintenance and repair of installations supplying your site,
  • to limit disturbances to the network generated by your installation.

More details on these conditions are provided in your CART.
