NorthWestern Energy Adopts Smoke Detection Technology Over Power Shutoffs

Published on July 30, 2024

NorthWestern Energy (NWE) has decided to move away from considering a Public Safety Power Shutoff (PSPS) as a precautionary measure against wildfires. Instead, they are implementing a new strategy by installing smoke detection cameras throughout their system.

Initially, NWE had considered PSPS due to the increasing wildfire risk in Montana. PSPS involves temporarily shutting off power in specific areas to prevent electrical equipment from igniting wildfires during extreme weather conditions, such as high winds, high temperatures, low humidity, and minimal precipitation. These conditions can make power lines particularly vulnerable to sparking fires, especially in rural and wildfire-prone areas.

NWE’s announcement that they were monitoring the potential need for a PSPS garnered considerable public attention and concern. They clarified that a PSPS would be a last resort, used only when all other safety measures are insufficient. This cautious approach is essential for safeguarding communities, particularly in areas outside of major cities which are more susceptible to wildfires.

As part of their enhanced safety measures, NWE has installed their first smoke detection field camera near Helena. These cameras are designed to detect smoke early, allowing for quicker alerts to local firefighting agencies and first responders. This early warning system is expected to significantly improve the speed and effectiveness of wildfire response, potentially preventing large-scale disasters.

The implementation of smoke detection cameras is part of a broader trend where utilities are increasingly adopting new technologies to manage and mitigate wildfire risks. By prioritizing these technological solutions, NWE aims to reduce the likelihood of power shutoffs, which can be disruptive to customers.
