Exhibit 15.1



                    Report of Independent Accountants


To the Shareholders and Trustees of NSTAR:

We have reviewed the accompanying condensed consolidated balance
sheet of NSTAR and its subsidiaries as of September 30, 2001, and
the related condensed consolidated statements of income,
comprehensive income and retained earnings for each of the three-
month and nine-month periods ended September 30, 2001 and 2000
and the condensed consolidated statement of cash flows for each
of the nine-month periods ended September 30, 2001 and 2000.
These financial statements are the responsibility of the
Company's management.

We conducted our review in accordance with standards established
by the American Institute of Certified Public Accountants.  A
review of interim financial information consists principally of
applying analytical procedures to financial data and making
inquiries of persons responsible for financial and accounting
matters.  It is substantially less in scope than an audit
conducted in accordance with generally accepted auditing
standards, the objective of which is the expression of an opinion
regarding the financial statements taken as a whole.
Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material
modifications that should be made to the accompanying condensed
consolidated interim financial statements for them to be in
conformity with accounting principles generally accepted in the
United States of America.

We previously audited in accordance with auditing standards
generally accepted in the United States of America, the
consolidated balance sheet of NSTAR as of December 31, 2000, and
the related consolidated statements of income, comprehensive
income, retained earnings and cash flows for the year then ended
(not presented herein), and in our report dated January 26, 2001
we expressed an unqualified opinion on those consolidated
financial statements.  In our opinion, the information set forth
in the accompanying condensed consolidated balance sheet as of
December 31, 2000, is fairly stated in all material respects in
relation to the consolidated balance sheet from which it has been
derived.
