HYDERABAD, INDIA and LATHAM, NY– Wireless TT Info Services Limited (WTTIL), the tower arm of Tata Teleservices Limited (TTSL), a major Telecom Operator with a pan-India network, and Plug Power Inc. (NASDAQ: PLUG), an established leader in fuel cell power solutions, based in Latham, NY, USA, announced that they have entered into a purchase and maintenance agreement for fuel cell based power systems.

The agreement is for the purchase, installation and maintenance of 200 GenSys® prime power fuel cell systems to be installed at cell towers owned and operated by WTTIL in India. Plug Power will be establishing manufacturing and support operations in India and currently expects initial deliveries to begin in the fourth quarter of 2009. The Company expects to have all 200 GenSys units shipped by the end of March, 2010.

GenSys®, a continuous run power source, is presently targeted for cell tower sites with no or extremely unreliable electric grid service. Approximately ten percent of WTTIL’s towers currently operate completely off grid where the primary power is provided by diesel gensets.

“WTTIL is pleased to partner with Plug Power for the installation of fuel cells in our network,” said Col. Ramanand.B, Chief Operating Officer of WTTIL. “Not only is this a “green” solution for telecom sites in India, but also addresses the need for continuous power, particularly at locations in the country where power supply is not available. Ramanand continued, “In addition to this, the cheaper cost of power enables us to differentiate our offerings to the customers. I am excited at the prospects of installing these fuel cells in our network and look forward to increasing the numbers in the near future.”

“We are very privileged to be associated with the reputed Tata Group and look forward to a long lasting partnership,” said Mark Sperry, Vice President and General Manager of Plug Power’s Continuous Power Division. “The Indian telecom market opportunity is tremendous with the addition of over 50,000 towers expected annually over the next three to five years,” continued Sperry. “We view this anchor order as the first step in capturing a substantial portion of this large and growing opportunity in India.”

This agreement follows a successful field trial at a TTSL tower site in Uttar Pradesh during the summer of 2008. Indian petroleum major, Hindustan Petroleum Corporation Limited (HPCL), will be supplying the fuel for the systems.

Strata-gems management consultants served as the strategic advisors for this project, helping to negotiate the successful agreement between all three companies involved, and bring this clean energy technology to India.
