BOULDER — Xcel Energy says power has been restored to about 15,000 customers in Boulder after a massive outage Monday morning.
Xcel spokesman Gabriel Romero says the cause of the outage isn't known yet.
The Boulder Daily Camera (http://tinyurl.com/oewagvt ) reported that traffic lights went out at several major intersections but no major accidents were reported.
Originally, Xcel said about 24,000 customers were without power but later lowered the figure.
