An electrical substation fire in the south Las Vegas Valley Monday morning briefly left thousands without power.

A transformer at the NV Energy station at the corner of East Frias Avenue and Giles Street, near the South Point, burst into flames about 5:50 a.m., according to Metropolitan Police Department Lt. David Gordon.

After NV Energy crews de-energized the transformer, firefighters were able to pour water on the fire and extinguish it.

Police were called to the scene to assist with road closures.

The fire initially caused about 4,200 NV Energy customers, including the South Point, to lose power in the south valley. Power had been restored to all but a few dozen customers by 8:30 a.m.

Schools in the area had full power as of 8 a.m. No schools were evacuated, Gordon said.
