TEL AVIV-YAFO, Israel, December 11, 2025 (EZ Newswire) -- Prisma Photonics, a leading provider of advanced optical fiber sensing technology, today announced a trial deployment with Pacific Gas and Electric Company (PG&E), the nation's largest combined natural gas and electric utility serving over 16 million people, to deploy cutting-edge grid monitoring solutions traversing some of California's most challenging geographic areas in San Luis Obispo and Humboldt counties.

This comes as California's electrical grid faces surging data center demand, extreme weather events, and aging infrastructure challenges that require immediate solutions without the massive costs and complexity of traditional sensor installations.

The project transforms PG&E's existing fiber optic cables into a comprehensive grid monitoring system, providing real-time visibility into line performance across three transmission corridors from the coastline to harsh mountain terrain. It aims to demonstrate Prisma Photonics' Dynamic Line Rating (DLR) and asset health management capabilities while addressing a growing industry challenge: how to enhance grid reliability and capacity without the massive costs and complexity of traditional sensor installations.

Turning Existing Assets Into Grid Intelligence

Rather than installing expensive monitoring equipment across challenging terrain, Prisma Photonics' technology converts PG&E's existing optical fiber infrastructure, which is already part of the power network, into an advanced sensing solution. The approach eliminates the need for costly and long new sensor deployment projects while providing utilities with both dynamic line rating capabilities and comprehensive transmission monitoring through a single system.

Addressing Critical Grid Challenges

The deployment covers transmission lines that traverse some of California's most challenging geographic areas, where installing traditional monitoring equipment would be prohibitively complex and costly. The system provides real-time data on line temperature, strain, and environmental factors that affect capacity — delivering both accurate dynamic line rating and critical grid intelligence as utilities work to accommodate growing electricity demand while maintaining reliability.

California's grid faces mounting pressure from multiple directions: data center expansion, extreme weather events, and the need to maximize capacity from existing infrastructure. Traditional solutions often require years of planning, complex installations, and ongoing maintenance across remote locations.
