RTE rationalises the use of its existing infrastructure in order to improve grid performance, to prolong grid service life, to lower costs and to minimise its effects on the environment. While making sure that it is equipped to do so. For example with project OLLA (Overhead Lines Lifespan Assessment), RTE is able to estimate the level of damage of overhead power lines conductors, and thus determine when is the right time to replace them. As a result, RTE is able to ensure the reliability of its infrastructures at a lower cost.
More than 4 000 RTE workers (half of its workforce) are constantly being called upon to identify potential failures and repair any faults. Night and day, in stormy or freezing weather conditions and even on Christmas day, our 170 maintenance teams – spread across the entire country – respond incredibly quickly to restore power as swiftly as they can.
Proud of their role as providers of a public service, these women and men have built up a unique set of maintenance skills for working on live equipment: they repair equipment without de-energising it and without depriving anyone of electrical current. The storm for which the winter of 1999-2000 will be remembered involved them in a huge mechanical upgrade project that lasted for 15 years.

Maintenance is now becoming more high-tech and drones are being used to monitor infrastructure in inaccessible areas more effectively, for example.
