A transmission line that runs into the Eagle substation failed Tuesday morning, knocking out power to 30,000 customers in the region, according to Idaho Power. The outage was reported around 7:30 a.m.
At about 9:15 a.m., Idaho Power announced on Twitter that electrical service to some customers was coming back online. Shortly after 10 a.m., the utility said power was restored to everyone affected by the outage.
Four Boise School District schools were affected by the outage: Cynthian Mann, Shadow Hills and Pierce Park elementaries and Rivergen Junior High.
Classes continued through the outages and in some case, the district provided lanterns so schools would have light.
Never miss a local story.
Linda Clark, superintendent at West Ada School District, said schools in Eagle and Star and Centennial High School were blacked out.
An Idaho Power spokeswoman said the transmission line failure affected five substations and about 30,000 customers. The Eagle substation is on old State Street, while the other substations affected are near Star, Hewlett Packard, Joplin (Chinden and Cloverdale), and Gary (State Street at Gary Lane).
Traffic signals were out, and that slowed down morning commuters. Motorists are advised to treat dark signals as a four-way stop.
The area impacted is Veterans Parkway to Star Road, and Chinden Boulevard to State Street.

All west Valley customers restored. Still investigating cause, looks to originate in Eagle vicinity. All apologies for the inconvenience.— Idaho Power (@idahopower) March 31, 2015
If at all possible, motorists should avoid Chinden Blvd. until power is restored. Roads to south have power, working lights— Ada County Sheriff (@AdaCoSheriff) March 31, 2015
Officers say traffic lights on Ustick, Fairview, and connector into downtown are working fine.— Boise PD (@BoisePD) March 31, 2015
However, try to avoid McMillan, Chinden, and State as lights are still affected. Think about taking a street to the south on commute— Boise PD (@BoisePD) March 31, 2015
Power is out in Eagle area. Please be safe driving. Signal lights are out at all intersections. Treat inoperable lights like a 4 way stop.— Eagle Fire Dept (@Eaglefire_Dept) March 31, 2015
