Ambient Adjusted Rating (AAR) solutions
Ampacimon’s Ambient Adjusted Rating solution, GridBoost Lite, is a powerful and fully sensorless software tool designed to help utilities unlock more capacity from their existing transmission lines. This sensorless AAR solution is ideal for utilities seeking a fast, cost-effective way to comply with regulatory requirements like FERC Order 881 while improving grid efficiency. Ampacimon’s AAR solution works by applying industry-standard thermal models to ambient temperature and solar input, using a conservative fixed wind assumption. The result is a dynamic, hourly-updated ampacity value that can increase line capacity by up to 10%, helping utilities reduce congestion, defer infrastructure upgrades, and operate more sustainably.

Ampacimon’s webinar offers a comprehensive introduction to the company’s sensorless DLR solutions for optimizing transmission capacity—focusing in part on GridBoost Lite, Ampacimon’s Ambient Adjusted Rating (AAR) solution.This webinar is designed to help utilities understand how to comply with industry standards while also unlocking additional grid capacity and reducing congestion costs. The session explains how this approach enables utilities to increase line capacity by up to 15% without installing physical sensors, making it ideal for broad, cost-effective deployment The webinar also places GridBoost Lite in the broader context of Ampacimon’s GridBoost Suite, which includes:
- GridBoost Advanced: Adds forecasted wind data for more accurate AAR.
- GridBoost DLR: Uses line-mounted sensors for real-time Dynamic Line Ratings.
- Facility Rating: Calculates ratings for substations and equipment, not just lines.

About DLR technology
Dynamic Line Rating (DLR) is an advanced technology used in electric power transmission to optimize the capacity of overhead power lines based on real-time environmental conditions. Unlike traditional static ratings, which rely on conservative assumptions, DLR adjusts the thermal capacity of transmission lines dynamically, enhancing efficiency and reliability. By continuously monitoring factors such as temperature, wind speed, and solar radiation, DLR systems can make real-time adjustments to the line's capacity, ensuring optimal performance under varying condition. Discover the power of Dynamic Line Rating (DLR) in optimizing electric power transmission. Learn how DLR works, explore different line capacity ratings, and understand the technologies and benefits of Dynamic Line Rating.
