Sentrisense, a Megger Company, Secures Multi-Year Contract with TenneT to Scale Dynamic Line Rating Across High-Voltage Network
Sentrisense has signed a multi-year, multi-million euro contract with TenneT to deploy its Dynamic Line Rating (DLR) sensor technology and supporting software across selected high-voltage overhead lines. The agreement marks a significant step in TenneT's move from targeted DLR applications to a scalable, data-driven approach to grid capacity management.
Dynamic Line Rating is already well established within TenneT's operations in the Netherlands, where it has been applied for more than a decade. What's changing now is the scale at which it's being deployed.
As transmission grids face higher demand, growing congestion, and increasing pressure from electrification, operators need faster ways to unlock capacity without waiting for large infrastructure upgrades. DLR addresses that challenge directly by showing how much capacity a line can safely carry under real conditions, and that's where reliable field data becomes critical.
TenneT performs its DLR calculations in-house. For this project there were requirements for a flexible sensor deployment model, reliable line data, and a solution that integrates into existing operational processes. Sentrisense was selected because its technology meets that need. The sensors can be deployed quickly, including through drone-based installation, reducing operational disruption and eliminating the need for planned outages during installation.
As part of the Megger group, Sentrisense brings field-level monitoring capability into a wider ecosystem of testing, asset management, and data analytics supporting operators in managing the full lifecycle of critical power infrastructure.
For TenneT, this flexibility is central to the programme's value. The benefit of DLR varies from line to line, depending on weather conditions, static ratings, component limitations, and network priorities. Access to field data allows the operator to better target where DLR creates the most value, validate internal calculations, and continue refining its models over time.
“This agreement with Sentrisense enables us to install additional sensors on high voltage (HV) lines in the short term. As a result, we can make better use of the existing infrastructure without compromising grid reliability. Dynamic Line Rating is an important building block in making more efficient use of the existing grid”
said spokesperson for TenneT.
For Sentrisense, the agreement reflects a broader shift underway in grid monitoring. DLR is moving from isolated applications to scalable operational programmes. Transmission operators are no longer only asking whether additional capacity exists, they need to know where it exists, when it's available, and how to use it safely.
“We are proud to support TenneT as they expand the use of DLR across their network. This agreement reflects exactly the kind of practical, scalable application we believe will define the next stage of grid monitoring”
said Sebastian Cerone, CEO at Sentrisense.
By supporting TenneT’s DLR expansion, Sentrisense continues its work with transmission operators looking to operate the grid with more visibility, more flexibility, and confidence. As a Megger company, Sentrisense is part of a broader commitment to delivering integrated monitoring and insights across critical power infrastructure.
