Avista adjusts operations for summer

In response to dry conditions and increasing wildfire danger in the region, Avista is instituting temporary changes to power line operations in its Washington and Idaho service areas. Avista has implemented this operational change, now called Fire Safety Mode, for over 20 years, a press release said.

Fire Safety Mode modifies how the system automatically responses to faults, such as a tree branch or other debris that may contact a power line and disrupt service during periods of high-risk weather. 

In contrast to standard procedures where power lines may automatically attempt to re-energize, Fire Safety Mode may require a physical inspection of all or part of the powerline before it is re-energized. Although this approach may lengthen outage durations, it offers a substantial reduction in ignition risk, making it an integral component of Avista’s wildfire mitigation strategy.

“At Avista, we understand that safeguarding our communities from wildfire risk requires ongoing commitment,” said Heather Rosentrater, Avista president and CEO. “By continually enhancing our systems and working closely with local partners, we ensure that safety remains at the forefront of everything we do.”

Since the introduction of its Wildfire Resiliency Plan in 2020, Avista has undertaken a range of grid-hardening initiatives targeting high fire-risk areas. 

These measures include the replacement of wooden transmission poles with steel alternatives, the installation of fire-retardant mesh at pole bases, and the substitution of wooden crossarms with fiberglass components. 

In select locations, Avista intends to further mitigate wildfire risk by converting overhead powerlines to underground systems. Additionally, the company has enhanced its vegetation management practices to minimize the likelihood of tree contact with power lines.

In the most extreme conditions, Avista may implement a Public Safety Power Shutoff (PSPS) a targeted, temporary outage in areas facing severe wildfire risk. PSPS is a last-resort measure, used only when weather conditions such as high winds and low humidity create a heightened threat. Avista crews patrol affected lines before restoring power, and Community Resource Centers may be activated to support customers during extended outages, the release said.
