CUSIP No.  29406-L-2
--------------------

         This Amendment No. 1 to Schedule 13D is being filed by Benjamin Brant
to amend the Schedule 13D (the "Schedule 13D") originally filed by Mr. Brant on
August 2, 2001. Capitalized terms used but not defined herein have the meanings
assigned to such terms in the Schedule 13D.

Item 1.  Security and Issuer:
         -------------------

         Item 1 of Schedule 13D is hereby amended to read as follows:

         "Common Stock, $.01 par value per share of Environmental Power
Corporation, a Delaware corporation (the "Company"). The address of the
Company's principal executive office is One Cate Street, 4th Floor, Portsmouth,
NH 03801."

Item 2.  Identity and Background:
         -----------------------

         Items 2(b) and 2(c) are hereby amended to read as follows:

"(b)     Mr. Brant's business address is 7553 S. Gartner Road.

(c)      Mr. Brant was, until March 15, 2002, Chief Technology Officer of
         Microgy Cogeneration Systems, Inc. ("Microgy"), 1767 A Denver West
         Boulevard, Suite 15, Golden CO 80401. Microgy's principal business
         is environmentally sound power generation, including biomass and
         distributed generation. Mr. Brant is currently a consultant in the
         energy and environmental industries."

Item 4.  Purpose of Transaction.
         ----------------------

         Item 4 of Schedule 13D is hereby amended by adding the following before
the final paragraph of such Item:

         "On May 2, 2002, the Company and Mr. Brant entered into a Stock Option
and Right of First Refusal Agreement (the "Option Agreement"). Under the Option
Agreement, Mr. Brant granted the Company a transferable one year option to
purchase 1,820,486 shares of Common Stock owned by Mr. Brant. The option is
exercisable at $.35 per share. The Company is required to exercise the option to
purchase at least 342,857 of such shares by specified dates. On May 3, 2002, the
Company exercised the option to purchase 120,000 of such 342,857 shares. The
certificate representing the shares subject to the option has been deposited
with an escrow agent under an Escrow Agreement dated as of May 3, 2002. To the
extent any portion of the option expires unexercised, the underlying shares will
be subject to a transferable right of first refusal granted by Mr. Brant to the
Company for a 12 month period beginning upon expiration of the option. Under the
Option Agreement, 197,514 other shares of Common Stock were delivered by Mr.
Brant to the Company in satisfaction of amounts owed to Microgy by a company of
which Mr. Brant is a principal in connection with loans by Microgy guaranteed by
Mr. Brant under a June 2001 guaranty. Under the Option Agreement, an additional
753,066 shares owned by Mr. Brant are subject to a 24 month standstill (the
"Standstill") under which Mr. Brant has agreed not to sell them into the public
markets.

The foregoing descriptions of the Option Agreement and Escrow Agreement are
qualified in their entirety by reference to the Option Agreement and Escrow
Agreement, which are attached hereto as Exhibit 6 and 7, respectively, and are
incorporated herein by reference."

Item 5.  Interest in Securities of the Issuer:
         ------------------------------------

         Items 5(a) and 5(c) are amended to read as follows:

         "(a)     Mr. Brant may be deemed to own beneficially 2,435,552 shares
of Common Stock as of May 4, 2002, including 1,682,486 remaining shares subject
to the option in favor of the Company and 753,066 shares subject to the
Standstill under the Option Agreement.



                                                                 Page 4 of 31

         The shares beneficially owned by Mr. Brant represent 12.2% of the class
based on the 19,934,139 shares of the Company's Common Stock outstanding as of
May 4, 2002. The number of outstanding shares is calculated by subtracting from
the 20,251,653 shares of Common Stock reported to be outstanding as of April 23,
2002 in the Company's Form 10-K/A filed for the period ending December 31, 2001
317,514 shares, consisting of: (1) the 120,000 shares of Common Stock that the
Company purchased from Mr. Brant on May 3, 2002, pursuant to the Option
Agreement and (2) the 197,514 shares of Common Stock which Mr. Brant delivered
to the Company on May 3, 2002, in satisfaction of certain guaranty obligations
as described in Item 4. The 317,514 shares acquired by the Company on May 3,
2002 are being held by the Company as treasury shares and, therefore, are deemed
issued but not outstanding.

         Mr. Brant is a party to the Stockholders' Agreement described in Item
4. Within the meaning of Rule 13(d)(5) under the Securities Exchange Act of
1934, as amended (the "Act"), the terms of the Stockholders' Agreement could be
deemed to provide for an agreement among the parties thereto to act together for
the purpose of voting and disposing of equity securities of the Company.
Accordingly, the parties thereto could be deemed to be members of a "group" and
could be deemed to be beneficial owners of all of the securities held by such
group. Mr. Brant denies the existence of such a group and disclaims beneficial
ownership of the securities held by any other person.

         As of the date hereof, to the best knowledge of Mr. Brant, the table
below identifies all of the parties to the Stockholders' Agreement, in addition
to Mr. Brant and the Company, and states their ownership interests in the
Company as of May 4, 2002, based solely upon public filings.



                                                                    Page 5 of 31

/1/      Section 13 of the Exchange Act deems a person to be the beneficial
         owner of a security if that person has the right to acquire beneficial
         ownership of such security within 60 days (including through the
         exercise or conversion of another security). Pursuant to Section 13,
         any shares of Common Stock not outstanding which are issuable within 60
         days upon exercise or conversion of securities held by a person have
         been deemed to be outstanding for the purpose of computing the
         percentage of outstanding securities of the class owned by such person
         but have not been deemed to be outstanding for the purpose of computing
         the percentage of the class by any other person.

/2/      Based on the 19,934,139 shares of Common Stock outstanding as of May 4,
         2002 as calculated above in this Item 5(a).

/3/      This includes 389,872 shares of Common Stock which is issuable upon the
         exercise of the Warrant Mr. Eastman received in connection with the
         Exchange Agreement.



                                                                    Page 6 of 31

         (c)      On May 3, 2002, the Company exercised its option under the
Option Agreement to purchase 120,000 shares of Common Stock owned by Mr. Brant.
Pursuant to the Option Agreement, Mr. Brant also delivered 197,514 shares of
Common Stock to the Company in satisfaction of certain guarantee obligations as
described in Item 4."
