The Tennessee Valley Authority, a power provider to several Appalachian states, ordered rolling blackouts for a second straight day on Saturday as extreme cold sends demand for electricity soaring to record levels.
The authority, which is owned by the US government and serves 10 million people, ordered the utilities it supplies to begin outages Saturday morning after wind and cold knocked power plants off line and temperatures in Nashville hovered around 10F (-12C).
