Altergy Increases Production Capacity
Company Experiencing Growing Global Demand For Fuel-Cell Systems

FOLSOM, CA, November 4, 2010 – Altergy Systems today announced that it has expanded the capacity of its automated fuel-cell assembly line - the first and only one in the world - to support its increasing global customer demand and  continuing growth into new international markets.

These assembly-line enhancements increase Altergy’s production capacity to approximately $370 million annually in fuel-cell systems.

Altergy is the world’s first company to design fuel cells that can be mass produced at low cost.  The company’s emission-free systems are becoming the clean-energy solution standard for telecommunications back-up power and other mission-critical applications.

“These enhancements to our production process will enable us to more easily serve customer needs and meet growing demand for our products,” said Eric Mettler, Altergy president and chief executive officer.  “They also demonstrate our leadership position in the industry and will help us achieve our mission of Changing the Way the World Gets Its Power.”

In August, Altergy also announced a partnership with the Republic of South Africa  to build an additional Altergy manufacturing and assembly plant there to serve South Africa and other Sub-Saharan African markets.
