TenneT Awards โฌ1.5 Billion in High-Voltage Cable Contracts
TenneT, the largest grid operator in the Netherlands and Germany, awarded about โฌ1.5 billion in contracts for new highโvoltage cable systems. The program supports TenneTโs plan to strengthen its onshore network and connect more renewable power over the next decade.
Long-Term TenneT High-Voltage Cable Contracts
TenneT signed a multi-year Corporate Framework Agreement with eight specialist partners: Brugg Kabel (Switzerland),ย LS Cable & Systemย andย Taihanย (South Korea),ย NKTย andย Suedkabelย (Germany),ย Prysmian Groupย andย TKFย (Netherlands), and TBEA Shandong Luneng Taishan Cable (China).
These companies will supply and install 110, 150, 220, and 380 kV onshore AC cable systems in Germany and the Netherlands. In the coming years, TenneT plans to build about 900 km of high-voltage links in Germany and roughly 4,000 km in the Netherlands.
Grid Expansion to Support the Energy Transition
TenneT expects to invest up to โฌ100 billion in onshore and offshore grids as renewable energy replaces fossil fuels. Because this requires a huge build-out, TenneT focuses on long-term partnerships with specialized cable suppliers. In this way, all parties can plan capacity better, align designs, and innovate together.
These long-term agreements also allow manufacturers to adjust production processes and machinery. As a result, TenneT anticipates better materials, more optimized designs, and higher efficiency over time.
Longer Cables, Fewer Joints, Lower Impact
Today, TenneT typically installs cable sections of around 1,500 meters. However, within about two years, the operator expects to use lengths of 3 to 3.5 kilometers. Over time, and depending on voltage level, TenneT aims for continuous lengths up to around 5,000 meters.
Longer cables reduce the number of joints and construction steps. Therefore, they can lower environmental impact during installation, cut failure risk, and increase construction speed. This is especially important for large onshore projects that rely on trenching and horizontal directional drilling.
