The Maryland Public Service Commission on Wednesday approved Allegheny Power's proposal to refund customers for an energy-conservation surcharge, a PSC spokeswoman said.
LaWanda Edwards, the spokeswoman, said the PSC agreed to Allegheny's plan to credit customers who paid the surcharge as part of a light-bulb distribution program.
After getting numerous complaints from people who thought the bulbs were free, the PSC -- which originally approved it -- criticized how the program was handled.
In January, Allegheny officials conceded that the utility made mistakes and agreed to cancel the program.
Wednesday's PSC hearing was a formality allowing Allegheny to refund surcharge money collected from Oct. 3, 2007, to Jan. 16, 2008.
