State regulators have voted to penalize Southern California Edison $24.5 million for a 2011 windstorm that left more than 400,000 without power and an incident in which three people were electrocuted.
The California Public Utilities Commission approved the penalty Thursday that Edison had agreed to in March.
The commission says Edison gave inaccurate information on power restoration and violated safety standards during the 2011 windstorm that left 440,000 customers without power.
In a separate incident, the utility was blamed for a conductor that fell to the ground and killed a man, his wife and their son.
Edison did not immediately have comment, but the company said in a statement in March that the penalty is "in the public interest."
