Quickly and safely increase capacity on transmission lines by up to 40% with Dynamic Line Ratings
The industry’s only non-contact sensor requires no live line work and no outages
LineRate®
What are Dynamic Line Ratings?
Dynamic Line Rating uses sensors to monitor weather conditions that heat or cool transmission lines to calculate their true capacity in real time. DLR often allows significantly more power flow than a static or ambient adjusted rating over the course of the year, but also detects when flows should be reduced to continue safe and reliable operation.
Unlock Capacity on Your Existing Infrastructure
DLR is a quick, affordable solution to support load growth, maximize efficiency, and accelerate interconnection
Support Load Growth
Power demand is forecast to increase at 6x the pace of the past 20 years. With the proliferation of data centers, electrification, and advanced manufacturing, there is more demand on the grid than ever. Dynamic line rating unlocks an average of 20-40% more capacity on existing lines.
Keep Customer Costs Low
Usage of dynamic line rating technology reduces costly congestion, allows for more affordable renewable energy sources to be brought online, and reduces the likelihood of outages that require costly repairs. It is also a more affordable option vs. building out new transmission.
Accelerate Interconnection
With 2.6 TW of generation in interconnection queues, power generation can take years to connect. Dynamic line ratings can quickly and affordably help interconnect any type of new generation with 20-30% capacity gains.

FAQs
The use of DLR in operations provides grid operators with more visibility into their system and more control over their grid. This includes continuous optimization by addressing thermal limits. DLR can be used in operations to address existing thermal constraints identified either by a transmission operator or by an interconnected generator experiencing curtailment. Grid Operators can use these ratings for day-of and day-ahead markets.
When DLR technology is used in operations, historical line ratings can be analyzed to create probabilistic line ratings which can be available on a seasonal, monthly, or more granular level to inform the planning process. The additional data regarding the hourly / sub-hourly thermal rating that comes from DLR can help maximize the efficiency of transmission planning.
Most utilities that use LineVision DLR experience average capacity gains upwards of 30%, with some reaching the triple digits on certain lines. The capacity change will vary by a large set of variables, including; region, conductor/tower type, current rating methodology, utility risk profile, and climate. During the sales process, LineVision conducts rigorous profiling studies to analyze target lines and scope out a project with maximized benefit.
(DLR) differs from AAR by using real-time weather and wind data, resulting in more accurate and safe ratings. DLR provides enhanced operational awareness and risk reduction by avoiding overstated capacity and detecting potential anomalies. Additionally, sensor-validated DLR offers increased accuracy and deep learning capabilities compared to software-only models
LineVision’s line rating systems are designed to fully comply with NERC-CIP requirements if deemed in scope by the utility.
LineVision has successfully achieved ISO 27001:2022 certification for our Operationalized LineRate solution, demonstrating the comprehensive measures we have implemented to ensure the confidentiality, integrity, and availability of our customers' data. We have undergone rigorous 3rd party audits and assessments, which are updated annually, affirming that our information security controls meet the stringent requirements of the standard.
DLR can be deployed on new transmission projects, existing infrastructure, or to support the outages required for rebuilds and reconductoring. DLR is 5-7% of the cost of traditional transmission upgrades and can be installed in months without the need for outages.
LineVision’s scoping process identifies the most limiting spans along a line that require field monitoring. A typical installation will monitor a full range of sites with differing angles of incidence to wind, topography/sheltering, conductor type, and maximum operating temperature.
LineVision’s ratings model is continually trained and improved using sensor-based data as feedback. This training improves accuracy and confidence in delivered ratings. The model incorporates statistical distributions to deliver confidence intervals that provide a comprehensive rating product.
Hardware requirements are dependent on project scope and complexity; however, one sensor per 2-3 miles is a reasonable estimate.
Not currently, however, with demand spiking and economic development opportunities tied to electricity availability, a growing number of stakeholders are pursuing optimization solutions like GETs because we need quick solutions. The reality is, we need both GETs and new transmission.
LineVision offers line ratings to lines 69 kV and up. LineVision does not offer line ratings on lines below 69 kV at this time.
