AK Steel Pleased With U.S. Department of Energy’s Proposed Transformer Efficiency Standards


West Chester, OH, February 03, 2012—AK Steel (NYSE: AKS) said today that revised energy efficiency standards proposed by the U.S. Department of Energy (“DOE”) on February 1, 2012 are not expected to significantly impact the overall competitiveness of the company’s grain-oriented electrical steels (“GOES”) used in the manufacture of electrical distribution transformers.  In fact, AK Steel said that with respect to some types of distribution transformers the new standards have the potential for increasing the market for GOES.

AK Steel previously noted in a filing with the U.S. Securities and Exchange Commission that a potential risk factor for its GOES business was that the DOE might change efficiency standards in such a way that could substantially reduce the competiveness of electrical steel in such applications.

"We are pleased with the Department of Energy's proposed efficiency standards,” said James L. Wainscott, Chairman, President and CEO of AK Steel.  “We continue to believe that AK Steel is well-positioned to meet the needs of our power generation and distribution customers for years to come."

The revised efficiency standards as proposed by DOE would become effective in 2016.  In the interim, AK Steel said that it will engage in research and development efforts to minimize any impact that the new standards might have on the available market for its GOES products.
