Israel Electric Corporation and Prisma Photonics have signed an agreement to monitor more than 1,000 km of Israel’s national grid. The agreement extends IEC’s existing cooperation with Prisma Photonics which has been using optical fibres to monitor the national transmission grid since 2020. The extension will expand Prisma Photonics’ coverage to 20% of Israel’s transmission grid.

The solution will monitor events threatening the regular operation of the power network and alert on faults with exact geographical locations. Monitoring will allow better grid management, fast fault response, and increase the grid’s reliability. In addition, collected weather and grid data will optimise the existing network, paving the way to better integrate renewable energy sources on the path to net zero emissions and IEC’s long-term sustainable vision.

PrismaPower uses the existing optical fibre network to monitor hundreds kilometres on the grid. It measures weather conditions around the electrical lines, locating faults and vandalism. The information and alerts pinpoint the location of the closest power tower, enabling quick response to restore service to normal. PrismaPower also uncovers slow processes such as partial discharges, which can harm the network, thus allowing preventive maintenance and increasing the power network’s resiliency.

“We’re happy to expand our collaboration with Prisma Photonics and believe in the power of advanced technology to address environmental and climate challenges, taking the energy ecosystem forward,” said Amir Livne, Senior VP of Strategy and Innovation,  IEC. “Prisma Photonics adds an important aspect to Israel Electric Corporation’s commitment to innovation, developing and improving our existing grid while facing the growth in power demand and realising our long-term net zero and renewable energy visions. A reliable, valuable, and accessible electric supply for Israel must be maintained.”

“We are extending our coverage to 1,000 km using new technology to a span no one has attempted before. It is an impressive and trustful step by IEC, following our initial collaboration”, said Dr. Eran Inbar, Prisma Photonics CEO. “The extension could improve the Israeli power ecosystem, presenting an innovative solution to market obstacles here, in Israel, and abroad. Adding Dynamic Line Rating to assess transmission line capacity will enhance power delivery over existing lines during peak demand. Without installing additional sensors on the wires, all this will be accomplished over IEC’s existing optical fibre network.”
