PG Launches Dynamic Line Rating and Asset Health Monitoring to Modernize California's Grid
Pacific Gas and Electric Company (PG&E) has announced the successful launch of its Dynamic Line Rating (DLR) and Asset Health Monitoring (AHM) technology demonstration. This initiative aims to optimize electric transmission line capacity and proactively monitor asset health using advanced sensor technology and real-time analytics. The project, which has reached trial deployment status, is part of PG&E's broader strategy to expand and upgrade substation and transmission line capacity, reduce congestion, and ensure reliable service during extreme weather events. DLR technology allows utilities to adjust powerline ratings based on real-time weather data, enabling more efficient use of existing lines without the need for new infrastructure. PG&E is collaborating with several technology partners, including Heimdall Power, Prisma Photonics, Sentrisense, and Smart Wires, to evaluate these technologies over an 18-month field demonstration.
