Most of downtown Kalama was without power for several hours last night, after a problem cropped up at the Cowlitz PUD substation at the south end of town. At 5:41 pm, a breaker at the substation opened up, taking 1,126 customers off-line. The outage affected downtown Kalama, also extending up China Garden Road. They got power restored to about 900 of those customers at 9:30 pm, and completed all repairs at 11:30. At this point, it’s not known why the breaker opened up.
