The state Public Service Commission approved a rate hike Tuesday for Duke Energy Kentucky that will affect 95,000 natural gas customers in seven Northern Kentucky counties.
The PSC approved an annual revenue increase of $13 million, or 10.4 percent, for Duke. That's $4.5 million less than the utility sought.
Under the new rates, the company's monthly customer charge will increase to $16 from $12, and its gas delivery charge will rise from $2.67 per 1,000 cubic feet to $3.72 per 1,000 cubic feet.
For a typical residential customer using an average of 7,000 cubic feet per month, a monthly bill will rise $11.35, or $136.20 a year.
Never miss a local story.
The deal does not affect the price that customers pay for natural gas. Under the law, that commodity cost is passed on to consumers dollar for dollar, with no profit for the utility.
The new rates will take effect Jan. 4 and are only for natural gas customers. The rate hike doesn't affect the company's 135,000 electricity customers.
