Electric power transmission lines span the horizon at sundown as seen from San Gabriel, Calif., Wednesday, Jan. 17, 2001. California regulators ordered blackouts Wednesday for the first time in the state’s months-long electricity crisis, blaming utility credit problems and a tight national power supply for the outages. The rotating blackouts ordered shortly before noon first hit several hundred thousand customers in northern and central California and lasted about an hour, then switched to new blocs of customers.
