CHARLESTON, W.Va. -- State regulators have delayed the timeline for deciding whether to approve a special electricity rate for Century Aluminum's Jackson County plant.

Appalachian Power and several other parties told the Public Service Commission that they need more time to file additional briefs. They say they haven't yet received transcripts of recent hearings in the case.

The PSC granted their request last week. The commission extended the deadline for filing briefs by about a week.

Century Aluminum says it needs to reduce the plant's electricity costs so that it can restart the operation. The Ravenswood plant closed in 2009 and about 650 workers lost their jobs.

Century officials say they expect the PSC to issue a decision in mid-September.
