ITEM 1. SECURITY AND ISSUER
This statement relates to the Common Stock, no par value (the "Common
Stock"), of Plug Power Inc. (the "Issuer") with principal
executive offices located at 968 Albany Shaker Road, Latham, NY 12110.
ITEM 2. IDENTITY AND BACKGROUND
(a) The names of the persons filing this Schedule 13D are

The principal business address of Hans P. Black is 3655 rue
Redpath, Montreal, QC H3G 2W8.
(c) The principal business of the Reporting Persons is the
furnishing of investment advisory services. The principal
occupation of Hans P. Black is serving as Chairman of
Interinvest Consulting Corporation of Canada Limited.
(d) During the last five years, none of the foregoing entities
have been convicted in a criminal proceeding.
(e) During the last five years, none of the foregoing entities
have been subject to a civil proceeding of the type
specified in Items 2(d) or (e) of Schedule 13D.
(f) Hans P. Black, a reporting person, is a citizen of Canada.
ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION
Since reporting in a SC 13D/A filing dated Oct. 4, 2012, the
Reporting Persons have acquired an additional net quantity of
5,647,522 shares of Common Stock of the Issuer for an aggregate
purchase price of approximately $789,675 or $0.14/share. The
effect of these purchases has been to increase the Reporting
Persons' holdings of Common Stock of the Issuer from 8.23% to
15.29%. The source of funds for such transactions was derived
from investment advisory client accounts.
ITEM 4. PURPOSE OF TRANSACTION
The Reporting Persons originally acquired the Common Stock of
the Issuer for investment purposes, rather than as activist
investors. Over time, the Reporting Persons have had, and from
time to time may continue to have discussions with management,
other shareholders, and third parties regarding matters relating
to the financial condition, strategy, business, assets,
operations, capital structure and strategic plans of the Issuer.
The Reporting Persons are appalled by the recent actions of the
Plug Power Board, viewing it as a clear and uncalled for
destruction of shareholder value. After spending much time
contemplating the reasoning behind such an irrational proposition,
the Reporting Persons feel it is in the best interests of all Plug
shareholders to propose that an alternate board be voted in at the
next AGM.
The Reporting Persons intend to review their investment in the
Issuer on a continuing basis. Depending on various factors,
including the Issuer's financial position and strategic direction,
the outcome of the discussions referenced above, actions taken by
the Board of Directors of the Issuer, price levels of the
securities of the Issuer, other investment opportunities available
to the Reporting Persons, conditions in the capital markets and
general economic and industry conditions, the Reporting Persons may
in the future take such actions with respect to their investments
in the Issuer as they deem appropriate, including purchasing
additional securities of the Issuer, selling some or all of the
Reporting Persons' respective holdings in the Issuer and/or
otherwise changing their intention with respect to any and all
matters referred to in Item 4 of Schedule 13D.
ITEM 5. INTEREST IN SECURITIES OF THE ISSUER
(a) The Reporting Persons beneficially own 8,717,367 shares of
Common Stock representing 15.29% of all of the outstanding shares of
57,000,000 shares of Common Stock outstanding as of February 20, 2013,
as reported by Bloomberg. Of the 8,671,367 shares held by the Reporting
Persons on behalf of their clients: Interinvest Corporation Inc.
holds 7,905,367 shares or 13.87% of Issuer's outstanding shares;
Interinvest Consulting Corporation of Canada Limited
holds 30,000 shares for a total of 0.05% of the Issuer's outstanding
shares; and Interinvest (Bermuda) Ltd. holds 736,000 shares for
clients for a total of 1.29% of the Issuer's outstanding shares. Hans P.
Black holds 40,000 shares or 0.07% of the Issuer's outstanding shares
for his own account and 6,000 shares or 0.01% for a related account under
his control.
(b) The Reporting Persons may be deemed to have the shared power to
vote or to direct the vote of (and the shared power to dispose of or
direct the disposition of) the 8,717,367 shares of Common Stock held.
This power is shared with the Reporting Persons' investment advisory
clients where applicable. Hans P. Black, by virtue of his relationship to
each of Interinvest Corporation Inc., Interinvest Consulting Corporation
of Canada Limited, and Interinvest (Bermuda) Ltd. may be deemed to
indirectly beneficially own 8,717,367 shares of Common Stock. Hans P.
Black disclaims beneficial ownership of such Common Stock for all other
purposes.
