Address Short-Term and Near-Term Issues

Address Short-Term and Near-Term Issues


Planning and operating the grid involves a growing number of stakeholders and is increasingly challenged by new technologies, changing regulations and heightened expectations for reliability and affordability. Because of the changing dynamics of load and generation, transmission issues are appearing – and sometimes disappearing – at an unprecedented pace. Typical network solutions do not offer the speed-of-installation or the flexibility that these emerging problems demand.


For a US-based utility, permitting and construction delays pushed back the in-service date of a large new line by 3 years. During that window, residual overloads cause NERC reliability violations. Using traditional tools, the utility has two choices; first, they could reconductor the overloaded facility. Alternatively, they could re-dispatch more expensive generation. These choices both place undue burden on customers.

A mobile deployment of Smart Wires modular power flow control technology is the ideal way to solve this short-term need. The mobile solution can be installed quickly and easily relocated once the new line comes into service and the reliability concerns disappear. Placing Guardian technology on the overloaded line pushes power to other paths with available capacity. This option requires 40% less investment compared with the reconductor. Smart Wires solution provides value to the grid for its entire lifetime and enables the utility to exercise good capital stewardship.
