About 25,000 BC Hydro customers in Kamloops were without power after an explosion at a substation knocked out power to most of the city around 7:30 a.m. PT Tuesday.

No one is believed to have been hurt in the blast, which occurred as hydro crews were inside the substation.

Power to most customers in the B.C. Interior city was restored by about 9 a.m.

Meanwhile, in Vancouver about 1,000 customers were still without power after an underground fire shutdown power to a large area of the downtown core. There is no indication the two events are related.
