Grid Resilience Systems

Innovative Proven Methods for Grid Recovery and Hardening

Lindsey has been improving grid resilience since decades before the term existed. Lindsey’s portfolio of Grid Resilience Systems encompasses the three major aspects of resilience: Hardening, Advanced Capabilities, and Recovery. Explore Lindsey’s resilient solutions; always ready.


Resilience Through Recovery

Emergency Transmission Towers

Weather or willful attacks can play havoc with transmission lines. Any transmission tower collapse or damage requires removing that line from service. Consequences range from a mere nuisance, to limiting power transfer, inability to serve load, reducing reliability, or worse. Often, scenarios involve multiple towers at the same time.

Lindsey Emergency Restoration System (ERS) structures are pre-kitted, modular guyed transmission towers. ERS structures can be rapidly deployed to the most remote locations and be quickly assembled by any available erection method. Proven over 30 years, there is no faster way to get conductors back in the air, moving power. Lindsey ERS structures provide the time to methodically repair or replace damaged towers.

Sharing Lindsey ERS Structures for Enhanced Recovery

All parts within a Lindsey ERS system are completely interchangeable. In the USA, hundreds of Lindsey 1070-series ERS structures are in place at utilities across the country. Any tower fall down exceeding a utility’s ERS structure inventory can be augmented by asset sharing from neighboring utilities. Lindsey’s GRIDSURANCE® asset sharing program, established in 2006, can direct utilities to locate nearby ERS structure assets.

Resilience Through Hardening

Transmission Tower Security Monitor

Tower tampering – cutting of steel, removing bolts, etc. – is a common threat posed by individuals of various motivations. The Lindsey TLM™ Security transmission tower monitor’s combination of vibration and infra-red sensors provides early warning of intrusion around the base of transmission towers that could compromise tower integrity. The TLM Security monitor is ideal for surveilling critical dead-end towers.

A member of the TLM-family of transmission line monitors, the TLM Security monitor is self-powered and can communicate via mesh or satellite radio, the latter being suitable for remote tower locations.

Resilience Through Advanced Capabilities

Reliability-Based Transmission Line Ratings

Events that may test transmission grid resilience are varied. Those involving minimal damage can be recovered from quickly. Other events require much more time when extensive damage has occurred. While some events provide an opportunity to prepare, others develop too quickly.

Transmission network resiliency consists of the ability both to resist failure and to rapidly recover from failure. Both sides of transmission grid resiliency can be aided by pre-deployment of Lindsey SMARTLINE transmission line rating and forecasting systems (Learn More). A next-generation dynamic line rating (DLR) system based on continuous learning, SMARTLINE can improve grid resiliency in a way that is cost effective, while providing ongoing operational benefits when not being used for resiliency purposes, including:

  • Widespread preemptive installation allows determination of long-term line overload ratings that are necessary when facing sudden yet long-term absence of major assets.
  • SMARTLINE can alleviate congestion and other constraints that may appear during recovery.
  • SMARTLINE can provide the added capacity required by lower-voltage lines in such events.
  • SMARTLINE may act as a line capacity buffer of sorts to reduce or prevent cascade line tripping.
