Reliable electricity supply The infrastructure that TenneT manages makes it possible to transport electricity via high-voltage power lines and substations, in almost all weather conditions. TenneT is responsible for the upkeep of all the infrastructure in the Netherlands above 110 kV and for the international connections. In a large part of Germany TenneT is responsible for the upkeep of the infrastructure above 220 kV and the offshore connections. To guarantee a reliable electricity supply we have to carry out regular inspections and maintenance work, which we plan in consultation with the regional grid operators and our connected customers. We always try to assess the condition of our electrical installations without shutting them down. We draw up long-term maintenance plans based on the outcome of our inspections and do everything possible to lengthen the interval between maintenance work, without losing sight of the required availability. The work is carried out by TenneT specialists who can detect faults in the network and assess how serious these are. Their observations are vital for assessing the quality of our equipment and we often adjust our maintenance strategy accordingly.
