The North Carolina Supreme Court will hear a case Tuesday claiming Duke Energy's latest rate hike is harmful to customers and should not have been granted. Attorney General Roy Cooper hopes the high court will strike down Duke's rate hike and change the way future increases are approved by regulators.
Duke Energy originally asked for permission to raise rates for the average household by 17%, but regulators agreed to just 7%.
Even at that lower rate, Duke managed to lock in a 10.5% profit for shareholders, which is where Attorney General Roy Cooper takes issue.
