Case Study: PPL Electric achieves lower congestion costs and improved transmission performance with Ampacimon dynamic line ratings

PPL Electric saves $23 million in congestion costs with Ampacimon

PPL Electric faced congestion issues on three historically congested transmission lines, which was increasing costs and limiting performance. To address this, they partnered with vendor Ampacimon to implement a dynamic line rating (DLR) solution using a network of sensors and a central analytics server.

Ampacimon's solution involved installing 75 sensors across 186 km of lines to collect real-time grid data. This data was integrated into PPL Electric's operations, providing a holistic view of line performance and enabling real-time adjustments. The results included a capacity gain of up to 16%, over $23 million saved in congestion costs on one line, and $50 million in avoided rebuild costs, which helped keep customer rates low.
