UPDATE, 9 p.m., October 28 | NV Energy activated its proactive shutdown plan for the Mt. Charleston region on Monday.

According to NV Energy spokeswoman Ashley Cabrera, power was shut off to 483 customers at 7:43 p.m. Monday.

The outage is expected to last until 10 a.m. Tuesday.

Customers affected by the shutdown will be notified by phone, text message and email.

NV Energy had originally planned to activate its public safety outage management starting Sunday, but Cabrera said it held off shutting off power because of changing weather conditions.

ORIGINAL | NV Energy has ordered a planned power outage for residents of Mt. Charleston, which includes Angel Peak and Kyle Canyon, due to increased fire conditions in southern Nevada.

The Public Safety Outage Management (PSOM) Watch will target approximately 466 NV Energy customers and will begin at 10 a.m. Sunday through Tuesday, October 29, at approximately 10 p.m

PSOMs are a preventive measure that NV Energy takes to prevent a wildfire based on extreme weather conditions.

According to NV Energy, a PSOM watch means that certain weather conditions such as high winds, low humidity and heat may require us to proactively shut down equipment to ensure the safety of our community and prevent the development of a potential wildfire.

Potentially affected customers in each area will be notified by phone, text, email messages and on NV Energy’s website at nvenergy.com/psom.

This potential proactive outage will impact a small portion of the total number of NV Energy customers in Southern Nevada and will be adjusted or canceled as weather conditions change.

The outage time frame includes the duration of the weather event and an estimate of how long it will take for crews to shut off power before the event and inspect lines for damage, vegetation or debris to begin safely restoring power once weather conditions stabilize start.

Recovery time may change due to weather conditions or if crews need to make repairs to equipment.

A PSOM event is an important defensive measure to protect the community and the environment from wildfires.

During a PSOM event, power is shut off as a safety measure to prevent power lines or debris entering power lines and other equipment from causing a wildfire when certain environmental conditions are met.
