Two traffic accidents and equipment failure caused three separate power outages today that affected about 2,400 Hawaiian Electric Co. customers.

Utility poles were damaged in traffic accidents on Makaha Valley Road near Noholio Road, and Kane'ohe Bay Drive and Hako Street at 1:27 a.m. and 4:49 a.m., respectively.

HECO spokesman Jose Dizon said 800 customers in Makaha lost power from 1:27 to 3:30 a.m. About the same number of customers in Kane'ohe were without power until 8:07 a.m., Dizon said.

Power to another 800 customers in parts of Wai'alae, Kaimuki and Kapahulu was cut from 6:09 a.m. to 6:28 a.m. because of a switch failure during routine maintenance work on a transmission line, said Dizon.

In the Makaha accident, a 17-year-old boy was taken in serious condition to The Queen’s Medical Center. Police said the boy was a front-seat passenger in a sports utility vehicle that hit the utility pole. The driver, a 20-year-old man, said he swerved to avoid a head-on collision with another vehicle that had crossed the center line. The driver and a woman, 20, who was seated in back, were not seriously injured.

A man, 27, injured in the Kane'ohe crash that involved a pickup truck was taken in guarded condition to Castle Medical Center.

Replacement work on the two poles was expected to take all day, said Dizon. Roads in both areas were closed to traffic.
