Century Receives Positive Ruling on Hawesville Power From Kentucky Public Service Commission

CHICAGO, IL--(Marketwired - August 14, 2013) - Century Aluminum of Kentucky, a
wholly owned subsidiary of Century Aluminum Company (NASDAQ: CENX), announced
today that the Kentucky Public Service Commission has approved agreements among
Century Aluminum, Big Rivers Electric Corporation and Kenergy that will allow
Century to purchase market-priced power for the Hawesville aluminum smelter
beginning August 20, 2013. While these agreements remain subject to certain
conditions, as well as approvals from various third parties, they will allow
for continued operation of the Hawesville smelter following the expiration of
the current power contract on August 19, 2013. 

The Hawesville smelter, located in Hancock County, KY, has an annualized hot
metal production capacity of 252,000 metric tons of primary aluminum and
employs approximately 650 men and women. "We are pleased to have reached this important milestone," commented Michael
Bless, President and Chief Executive Officer. "We are grateful for the
unwavering support of regional union leadership and the community as a whole.
In addition, we appreciate the Public Service Commission's timely consideration
and approval of the agreements. This result also reflects the extraordinary
dedication and sacrifice of our employees at Hawesville, of whom our directors
and I are extremely proud."

Mr. Bless continued, "Throughout this process, the Hawesville plant has
continued to make gains in key operating metrics and efficiencies. These
efforts and the team's intense focus on safety are the building blocks for a
successful operation. As we have maintained, a market power arrangement is a
critical enabler for this plant to continue to operate and we believe this
agreement will allow the plant to be competitive in the world market over the
long-term. "We will, per the terms of the agreement we reached in June, begin to receive
market-priced power for Hawesville beginning on August 20," concluded Mr.
Bless. "There are additional requirements that must be satisfied to provide for
the plant's long-term operation. Most importantly, we must agree, with the
operator and regulator of the regional transmission system, on operating
procedures and the installation of necessary equipment to assure the stability
of the grid. These efforts will require some additional months to complete,
during which time we will reimburse Big Rivers for any incremental costs
associated with continued temporary operation of the Coleman Generating
Station. We are now preparing to move Sebree to a similar market-priced energy
arrangement when its power contract expires on January 31, 2014."

To allow time for the satisfaction of closing requirements and conditions,
Century will extend the date of the plant closure cited in the April WARN
notice from August 20, 2013 to October 18, 2013, during which time the company
will work vigorously to bring the transaction to a final conclusion. Once all
the conditions are met and approvals received, the WARN notice will be
rescinded.
