California ordered a stage-2 power-grid emergency -- one step away from rolling blackouts -- as a searing heat wave drives temperatures into triple-digits and sends demand for electricity soaring.

The state’s grid operator called for the measure as wildfires -- including the Bootleg Fire in south-central Oregon -- threaten transmission lines bringing power into California. It comes as a historic drought grips the Western U.S. and temperatures reach record levels in parts of the region.
