Since January 1, 2009, Plug Power has received purchase orders for a total of 380 GenDrive systems, with pending orders of 92 units, and further sales currently in negotiation. Orders have been received from customers including food and beverage distributors and retailers, grocers and automotive manufacturers.

Market demand for GenDrive is increasing as customers move from trials to full fleet conversions. Their decisions are based on an increase in productivity, operator satisfaction, proven return on investment and a reduction in on-site carbon emissions. The GenDrive solution has delivered on its promise to bring value to the end user and continues to drive the paradigm change in powering material handling equipment.

"Our progress so far this year is a testament to the real economic and environmental value proposition offered by GenDrive," said Andy Marsh, President and CEO of Plug Power. "Customers are today opting to convert full fleets of lift trucks and build new facilities using exclusively fuel cells for lift truck power."

Plug Power will be holding an analyst and investor day on October 8, 2009 at which Marsh will expand on the Company's path to profitability. Plug Power will host a live webcast for the event.

 Date: Thursday, October 8, 2009
 Time: 10:45 am ET

The webcast can be accessed by going directly to the Plug Power Web site (www.plugpower.com) and selecting the webcast link on the home page. The webcast slides will be archived for a period of time following the meeting.
