Address Short-Term and Near-Term Issues

Address Short-Term and Near-Term Issues

Background

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.

Problem

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.

Solution

Smart Wires’ quickly deployable, modular power flow control technology offers a preferable solution. Placing Guardian technology on the overloaded line pushes power to other paths with available capacity. This solution requires 40% less upfront investment compared with the reconductor and can be relocated elsewhere on the system once the large new line comes in-service and the reliability concerns disappear. This technology will provide value to the grid for its entire lifetime and enables the utility to exercise good capital stewardship.
