This Amendment No. 1 (this "Amendment") amends the statement on Schedule 13G filed on May 27, 2011 (the "Original Schedule 13G" and the Original Schedule 13G as amended, the "Schedule 13G"), with respect to shares of common stock, par value $0.01 (the "Common Stock"), of Plug Power Inc., a Delaware corporation (the "Company"). Capitalized terms used herein and not otherwise defined in this Amendment have the meanings set forth in the Schedule 13G. This Amendment amends and restates Items 2(b), 2(e), 4 and 5 in their entirety as set forth below.

Item 2(b).
ADDRESS OF PRINCIPAL BUSINESS OFFICE OR, IF NONE, RESIDENCE

 
The address of the business office of each of the Reporting Persons is:
   
 
1 Rockefeller Plaza, Suite 1205
New York, NY 10020

Item 2(e).

Item 4.
OWNERSHIP.

The information as of the filing date required by Items 4(a) – (c) is set forth in Rows 5 – 11 of the cover page for each Reporting Person hereto and is incorporated herein by reference for each such Reporting Person.

The percentage set forth in Row (11) of the cover page for each Reporting Person is based on 22,736,504 shares of Common Stock issued and outstanding as of November 7, 2011, as represented in the Company's Quarterly Report on Form 10-Q for the quarterly period ended September 30, 2011, filed with the Securities and Exchange Commission on November 9, 2011 and assumes the exercise of the reported warrants (the “Reported Warrants”) subject to the Blocker (as defined below).

Pursuant to the terms of the Reported Warrants, the Reporting Persons cannot exercise any of the Reported Warrants until such time as the Reporting Persons would not beneficially own, after any such exercise, more than 4.99% of the outstanding shares of Common Stock (the "Blocker"), and the percentage set forth in Row (11) of the cover page for each Reporting Person gives effect to the Blocker. Consequently, at this time, the Reporting Persons are not able to exercise all of the Reported Warrants due to the Blocker.

Therefore, as of the date hereof, each of the Reporting Persons may be deemed to beneficially own 4.99% of the outstanding shares of Common Stock of the Company.  The foregoing should not be construed in and of itself as an admission by any Reporting Person as to beneficial ownership of shares of Common Stock owned by another Reporting Person.

If this statement is being filed to report the fact that as of the date hereof the reporting person has ceased to be the beneficial owner of more than five percent of the class of securities, check the following: [X]
