Teréga is committed to its policy of continuous improvement in the quality of its services and activities.

With this in mind, Teréga has been using a system of performance indicators since 2009, integrated into the transport activity regulation system.

The service quality indicators were changed with the introduction of the ATRT5 tariff in April 2013: there are now fourteen indicators, but they are still split into four themes identified as having a direct impact on the smooth running of operations for transport infrastructure users :

According to CRE's demand, Teréga publishes a qualitative analysis of the Service quality indicators.

4 indicators for the reliability of metering data and consumption forecasts : 

7 indicators on the reliability of exchanges with users of transport infrastructures affecting the smooth running of their activities.

2 indicators qualifying our interventions on the markets for the purposes of balancing and the consistency of the linepack level from one day to another.

5 indicators for adherence to forecast maintenance programmes and capacity reductions.

2 indicators for emissions of greenhouse gases.

Quality levels have been set by the CRE for the majority of indicators for metering and exchanges with third parties.

In addition, a financial incentive mechanism applies to the first 4 indicators for metering along with shipper portal availability: Teréga is awarded bonuses/penalties depending on the results achieved.
