Newly released federal data show that Consolidated Edison's 2012 residential electricity prices were the highest of any major U.S. utility.
The data from the U.S. Energy Information Administration shows that Con Ed's 2.1 million residential customers in New York City and Westchester County paid an average of 25 cents per kilowatt hour in 2012.
That's more than twice the national average price of 12 cents per kilowatt hour.
Con Ed said in a statement that more than 25 percent of the bill consists of government-imposed taxes and fees.
Long Island Power Authority customers also pay some of the country's highest rates.
LIPA's (LY'-puhz) 1 million residential customers paid 19 cents per kilowatt hour last year.
LIPA says there will be no rate increase in its 2014 budget.
