TRENTON - (AP) The head of the agency that regulates New Jersey's utilities gives the state's power companies an 'F' for how they communicated with customers and mayors during Superstorm Sandy.

Board of Public Utilities President Bob Hanna says the utilities need better methods of telling customers when their power will be restored.

Hanna and utility executives testified before the Senate Budget Committee, which examined how the power providers responded to the superstorm.

The historic storm socked the state on Oct. 30, leaving 2.7 million customers in the dark.

PSE&G CEO Ralph LaRossa says it cost $250 to $300 million to restore power and much more to move low-lying substations.

Recommendations include improving communication, building stronger energy systems and more aggressive tree trimming.
