Harris said Thursday afternoon he had yet to "dig in" to the finer points of the 70-page order.
"I can't really say (if his division supports the special rate)," Harris said. "We have 15 days to file for ... the commission to reconsider so I'll be deciding that over the next 15 days -- actually before that because we'd have to get working on a filing."
The commission's approval for the special rate mechanism will expire at the end of the year.
Appalachian Power spokeswoman Jeri Matheny said the company would support the PSC's new rate proposal.
"For the most part we're glad the commission was able to reach what seems like a reasonable plan of action," Matheny said. She added that company officials are especially glad the newly proposed rate will put risk not on other Appalachian Power customers, but on Century.
"The ball is in Century's court for them to make a decision if they can restart under these guidelines," Matheney said.
Calls to Century officials were not immediately returned Thursday.
Earlier this year, state lawmakers approved a tax credit worth up to almost $20 million a year intended to help the Century plant reopen. The PSC said Thursday that its ruling includes that tax credit.
When Century's Ravenswood plant shut down in 2009, more than 650 workers were laid off. Company officials have said about 450 jobs could be returned immediately if the plant reopened, and 200 jobs could be added later.
Hundreds of Century Aluminum retirees lost the health benefits promised to them under union contracts in July 2011. In March of this year, the retirees voted to accept a deal that would restore part of those benefits - a step they hoped would help lead to the reopening of the plant."Many have asked what this ruling means to the retirees and at this time, we are not sure," Karen Gorrell, a spokeswoman for the Century retirees, said in a statement Thursday. "We do know that the restart of the plant hinges on a special rate that Century can live with and that will help them operate through periods of fluctuating ... prices on aluminum products. How Century will view this PSC decision is the most important question that will have to be answered."
