The modifications proposed by Century in the future restart option represent "major changes to the Commission-approved plan and we believe they would be best considered in a new proceeding," the PSC said.
That proceeding shouldn't be filed until the smelter company has "attempted to discuss and resolve a plan with" Appalachian Power, the PSC said.
Century has options, according to the PSC.
Susan Small, a PSC spokeswoman, said now is the time for Century to meet with the other parties involved -- and negotiate -- if the Ravenswood plant is to reopen.
Those other parties are Appalachian Power, the PSC's Consumer Advocate Division and the West Virginia Energy Users Group.
"Nothing ... precludes Century, [Appalachian Power] and others from continuing to discuss a more acceptable special rate mechanism," the PSC said.
The PSC wants the smelter to start doing business again.
"The Commission wants the Ravenswood plant to resume operation, and we hope to facilitate an acceptable power contract by describing some of the problems that we have with the Century proposals," the PSC wrote.
"The PSC is not shutting the door and saying they can't open the plant. What Century had done was, they put two new offers on the table, and this is not how this process works. They need to negotiate with the other parties," Small said.
In its filing, the PSC responded to nine modifications that Century had requested to "enable Century to consider a future restart of the Ravenswood production facility," the PSC wrote.
For example, Century said that the implementation of the special electricity rate shouldn't require the company to restart the plant at any specific time within a 10-year window that the special rate would be in effect.
The PSC responded by saying it would not approve a special electricity rate and contract that may be exercised at any time in a 10-year window because "a 10-year option ... is not reasonable, particularly considering the size of the Century load."
Byron Harris, director of the Consumer Advocate Division, said Friday that Century has 30 days to appeal the commission's order to the state Supreme Court, but he doesn't see that happening.
"There's not much grounds for an appeal. I'd think it'd be extremely difficult to find the commission made an error," Harris said. "The commission stood by its original decision, which tried to balance all of the interests in the case. I'm glad they stood by that decision, and now it's up to Century to see if they're willing to take on the risk of running their own business."
