On Thursday's conference call, Bless said the restart of the Ravenswood plant remained a top priority but parts of the PSC's plan "simply don't work for us."
The company has asked for reconsideration, although the PSC has made clear in filings it will not consider pushing any additional costs onto other ratepayers.
Bless said the PSC's rate structure would not allow the company to recoup its $90 million in upfront restart costs. If they must use the PSC plan, the company would have to wait for the global economy to improve.
"We wouldn't restart the plant under current economic conditions," he said. "In essence we would sit and wait for better economic conditions."
The PSC plan also requires Century to sign a formal guarantee that it or its parent company will pay for any power costs that remain at the end of the 10-year rate plan.
The company argues that guarantee should come only from the Century of West Virginia subsidiary company, not the parent corporation. Bless said taking on the guarantee could hinder Century Aluminum's overall corporate finances.
"We have obviously said that that part of their proposal makes no sense to us," Bless said. "To us, that would simply be frankly borrowing our losses, and on behalf of our shareowners, that makes no sense at all."
Bless said the company expects to hear something back from the PSC in the next week.
