Attacks on Pacific north-west power stations raise fears for US electric grid. At least six attacks, some of which involved firearms and caused residents to lose power. Two of the attacks shared similarities with the incident in Moore county, North Carolina, where two stations were hit by gunfire causing 40,000 to lose power.
