EU-338 Line stringing and tower erection for large projects
TenneT TSO is launching a digital qualification procedure via Mercell to compile a list of suitable contractors for the installation of high-voltage lines and the erection of towers. The assignment includes both upgrades of existing high-voltage lines (approximately 600 km between 2026 and 2035) and the construction of new lines (approximately 400 km in the same period), representing a total demand of circa 1,000 km until 2035. The procedure focuses on line/conductor stringing and tower erection around new and existing high-voltage lines. Contractors must demonstrate experience with large-scale high-voltage projects, comply with safety and quality standards, and possess the necessary resources and personnel. The procedure is entirely digital, promoting transparency and efficiency. TenneT expects demand to be three times higher than current levels, making a robust network of partners essential.

TenneT faces a major task in the coming years. In addition to a substantial number of upgrades to existing high-voltage overhead lines (around 600 km between 2026-2035), a substantial number of new high-voltage overhead lines is planned to be build (around 400 km between 2026-2035). This possibly leads to a total demand of 1000 km till 2035, which means a tripling (x3) of the current demand. Please note: This is the current forecast; depending on various factors, the actual number of projects may be higher or lower. With this qualification system, TenneT wishes to establish a list of suitabl
