Charlotte, NC-- A Duke Energy Carolinas electricity rate increase that took effect last year will stay in effect while state regulators review it under a state Supreme Court order.
The Charlotte Observer reports that the North Carolina Utilities Commission on Monday refused Attorney General Roy Cooper's request to put the 7 percent rate increase on hold during its review.
The Supreme Court in April ordered the commission to further examine last year's power cost increase. The court backed Cooper's claim that the commission didn't fully weigh the impact on customers.
Duke Energy Carolinas has 1.9 million customers from Durham to western North Carolina. The rate increase cost typical residential customers an extra $7 a month, beginning in February 2012. Duke is collecting an extra $310 million in annual revenue.
