California power grid operators ordered statewide rolling blackouts, cutting enough power for about 225
thousand homes for about an hour today.

The Independent System Operator says high temperatures in the state and tight electricity supplies led to the
outages.

Grid managers asked for 300 megawatts to be cut between the three utilities.

Pacific Gas and Electric officials say they cut between
125 megawatts in Northern and Central California affecting about 54 thousand customers.
