Prisma Photonics offers a groundbreaking approach to monitoring thousands of miles of power lines – leveraging existing optical fibre infrastructure, with no need for sensors on lines or towers. Real-time monitoring enhances grid resiliency against wildfires, icing, strong winds, electrical faults and physical tampering. This approach improves service reliability, grid safety and the ability to respond to threats from extreme climate events. 

Dynamic Line Rating (DLR) is also enabled by measuring wind conditions along each power line span. The system identifies the least-cooled critical span and adjusts capacity in real-time, safely increasing grid throughput without additional hardware. 

The technology is deployed through a simple substation-based installation that connects to existing optical fibre, eliminating the need for field installations or ongoing maintenance. Every span is continuously monitored, making the solution highly scalable across entire power grids.

Through their advanced, sensor-less, AI-driven Digital Twin technology, Enline empowers Transmission System Operators, Distribution System Operators, Energy Generation Companies and Industrial Sectors to optimize asset performance, reduce operational costs, and mitigate risks.

Enline’s solutions provide real-time monitoring, predictive insights, and actionable information to streamline energy management, anticipate potential failures, and improve grid stability. Their clients have achieved measurable results, including up to a 35% reduction in OPEX, 20% savings in CAPEX, and a 60% decrease in energy congestion.
