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

NorthWestern Energy and Smart Wires have secured grant funding from the U.S. Department of Energy through its SPARK program. This initiative will deploy new technologies across an existing transmission corridor connecting Montana and Wyoming.

Why it matters

The project aims to alleviate transmission constraints and increase the total transfer capability of the current electrical grid. By upgrading existing infrastructure, the collaboration seeks to demonstrate the practical application of advanced power flow and dynamic line rating systems.

The grant supports the integration of advanced power flow control and dynamic line rating technologies into an existing transmission corridor. The project is expected to enhance energy utilization levels across the Montana-Wyoming border.

The players

NorthWestern Energy

An energy provider serving regions in the American West that operates infrastructure across Montana and Wyoming.

Smart Wires

A technology company based in Research Triangle Park, North Carolina, that specializes in grid-enhancing hardware.

U.S. Department of Energy

The federal executive department responsible for national energy policy and the administration of the SPARK grant program.

The details

The project utilizes Smart Wires technology to optimize the flow of electricity through existing lines. This approach increases transmission efficiency between the two states without requiring the construction of entirely new corridors.

Market Landscape

The initiative aligns with the U.S. Department of Energy SPARK program to accelerate grid modernization efforts across the United States. This move positions the collaborators to address rising energy transmission constraints through software-driven hardware upgrades.

The upgrades to the interstate transmission corridor aim to increase the reliability and capacity of the regional energy supply. Consumers may see long-term benefits in grid stability as advanced management technologies are integrated into the existing infrastructure.

The takeaway

Advancing power flow control technology on existing lines allows utilities to increase capacity without the significant land use required by new builds. This model of grid optimization is becoming a preferred strategy for regional energy providers facing limited transmission bandwidth.
