Should the government prioritize upgrading existing power infrastructure over constructing new transmission lines?

NorthWestern Energy and technology provider Smart Wires received grant funding from the U.S. Department of Energy SPARK program. The project aims to improve transmission efficiency by using existing infrastructure between Montana and Wyoming.

Why it matters

By deploying advanced power flow control and dynamic line rating technologies, this project addresses transmission constraints to increase capacity on current lines. This reduces bottlenecks for companies dependent on consistent energy access in the region.

The project grant covers a single transmission corridor connecting Montana and Wyoming using existing infrastructure. The exact funding amount awarded by the U.S. Department of Energy remains undisclosed.

The players

NorthWestern Energy

An investor-owned utility providing electricity and natural gas services across Montana, South Dakota, and Nebraska.

Smart Wires

A power technology company based in North Carolina that develops grid-enhancing hardware to optimize transmission capacity.

U.S. Department of Energy

The federal agency responsible for energy policy, nuclear safety, and the administration of national power grid infrastructure grants.

The details

The initiative integrates Smart Wires' advanced power flow control and dynamic line rating systems into existing transmission lines. These technologies actively manage how electricity moves across the grid, allowing operators to move more power through current assets without needing new corridor construction. By optimizing the use of existing lines, the project aims to expand transfer capability for industrial and commercial power users in the region.

Market Landscape

This project aligns with the broader push to modernize grid infrastructure through the U.S. Department of Energy SPARK program. It highlights a shift toward grid-enhancing technologies that maximize existing assets rather than constructing new, capital-intensive transmission lines.

Business owners in Montana and Wyoming should monitor the projected increases in power transfer capability as the upgrades proceed. The deployment of these technologies may reduce operational risk associated with grid constraints for high-energy usage facilities.

The takeaway

Optimizing existing transmission lines with new control hardware is becoming a standard strategy for expanding regional grid capacity. Operators should track local utility filings for transmission upgrades that could signal improvements to energy reliability in their service areas.
