Alcan Rolled Products says in a document filed Thursday with the state Public Service Commission the increase would make it impossible for the company’s Ravenswood plant to compete in the struggling aluminum industry.
Century Aluminum says in a PSC filing the increase would severely affect its operations. Century closed its Ravenswood smelter and laid off approximately 650 people in February.
The companies are the latest manufacturers to oppose the increase, which AEP maintains is necessary primarily because of rising coal prices.
Separately, the PSC’s Consumer Advocate Division has declined to take a position on AEP’s request for an interim 18.5 percent rate hike starting July 1.
