The Application/Declaration in this file, as amended, is further amended as
follows:

Paragraph 13 of Post-Effective Amendment 14 (Amendment No. 16)  is deleted in
its entirety and replaced with the following new paragraph 13.

"Other Matters

     Except in accordance with the Act, neither NU nor any subsidiary thereof
(a) has acquired an ownership interest in an exempt wholesale generator
("EWG") or a foreign utility company ("FUCO") as defined in Sections 32 and
33 of the Act, or (b) now is or as a consequence of the transactions proposed
herein will become a party to, or has or will as a consequence of the
transactions proposed herein have a right under, a service, sales, or
construction contract with an EWG or a FUCO.  None of the proceeds from the
transactions proposed herein will be used by NU and its subsidiaries to
acquire any securities of, or any interest in, an EWG or a FUCO.

     NU currently meets all of the conditions of Rule 53(a),except for clause
(1).  At June 30, 2000, NU's "aggregate investment," as defined in Rule
53(a)(1), in EWGs and FUCOs was approximately $469.5 million, or
approximately 76.3 % of NU's average "consolidated retained earnings," also
as defined in Rule 53(a)(1), for the four quarters ended June 30, 2000
($615.3 million).  With respect to Rule 53(a)(1), however, the Commission has
determined that NU's financing of its investment in Northeast Generation
Company ("NGC"), NU's only current EWG or FUCO in an amount greater than the
amount that would otherwise be allowed by Rule 53(a)(1) would not have either
of the adverse effects set forth in Rule 53(c).  See Northeast Utilities,
Holding Company Act Release No. 27148, dated March 7, 2000.  NU continues to
assert that its EWG investment in NGC will not adversely affect the System.

     In addition, NU and its subsidiaries are in compliance with the other
provisions of Rule 53(a) and (b), as demonstrated by the following
determinations:

(i)   NGC maintains books and records, and prepares financial statements in
accordance with Rule 53(a)(2).  Furthermore, NU has undertaken to provide the
Commission access to such books and records and financial statements, as it
may request;

(ii)   No employees of NU's public utility subsidiaries have rendered
services to NGC;

(iii)  NU has submitted (a) a copy of each Form U-1 and Rule 24 certificate
that has been filed with the Commission under Rule 53 and (b) a copy of Item
9 of the Form U5S and Exhibits G and H thereof to each state regulator having
jurisdiction over the retail rates of NU's public utility subsidiaries;

(iv)   Neither NU nor any subsidiary has been the subject of a bankruptcy or
similar proceeding unless a plan of reorganization has been confirmed in such
proceeding;

(v)   NU's average CREs for the four most recent quarterly periods have not
decreased by 10% or more from the average for the previous four quarterly
periods; and

(vi)  In the previous fiscal year, NU did not report operating losses
attributable to its investment in EWGs/FUCOs exceeding 3 percent of NU's
consolidated retained earnings."


Pursuant to the requirements of the Public Utility Holding Company Act of
1935, as amended, the undersigned have duly caused this Post-Effective
Amendment to be signed on behalf of each of them by the undersigned thereunto
duly authorized.
