Exhibit 15.1


                       Report of Independent Accountants


To the Board of Trustees and Shareholders:

We have reviewed the accompanying condensed consolidated balance sheet of NSTAR
and its subsidiaries as of March 31, 2000, and the related condensed
consolidated statement of income and comprehensive income of retained earnings
and of cash flows for the three month period ended March 31, 2000. These
consolidated financial statements are the responsibility of 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
in order for them to be in conformity with generally accepted accounting
principles.

We previously audited in accordance with generally accepted auditing standards,
the consolidated balance sheet as of December 31, 1999, and the related
consolidated statement of income and comprehensive income, of retained earnings
and of cash flows for the year then ended (not presented herein), and in our
report dated January 26, 2000 we expressed an unqualified opinion on those
consolidated financial statements. In our opinion, the accompanying condensed
consolidated balance sheet information as of March 31, 2000, is fairly stated in
all material respects in relation to the consolidated balance sheet from which
it has been derived.
