Ampacimon’s Advanced Ambient Adjusted Rating (AAR+) solution, Gridboost Advanced, is a software-only, sensorless system that calculates the real-time and forecasted current-carrying capacity (ampacity) of overhead transmission lines. It builds on the basic AAR approach by incorporating forecasted wind data into the calculation, offering more accurate and dynamic ratings without requiring physical sensors on the 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 15%, helping utilities reduce congestion, defer infrastructure upgrades, and operate more sustainably.
