EU-367 Civil engineering works for major line projects
TenneT TSO is planning a major expansion of the high-voltage grid between 2026 and 2035, with an estimated total length of 1,000 km (600 km of existing lines and 400 km of new lines). The tender focuses on civil engineering works, including the installation of mast foundations and the construction of access roads for both new and existing high-voltage lines. The procedure is fully digital via the Mercell platform and utilizes a recognition scheme to establish a list of suitable contractors. The contract is intended to increase grid capacity and ensure the reliability of the energy transition. The tender is aimed at companies with experience in civil infrastructure and high-voltage projects, with a focus on quality, safety, and sustainability.

TenneT faces a major challenge in the coming years. From approximately 2026, in addition to a significant number of major upgrades to existing high-voltage lines (approximately 600 km between 2026-2035), a significant number of major new high-voltage lines are also planned to be built (approximately 400 km between 2026-2035). This may lead to a total demand of 1,000 km until 2035, which represents a tripling (x3) of the current demand. n nNota bene: This concerns the current expectation; depending on various factors, the number of projects may ultimately be higher or lower.n nTenneT wishes to
