Explanatory Note and Request for Waiver

National  Grid's  subsidiary  National  Grid USA (the  successor  to New England
Electric System ("NEES")) was subject to the periodic reporting  requirements of
the Securities  Exchange Act of 1934, as amended,  and the rules and regulations
of the Commission  thereunder.  Prior to the merger with National Grid, National
Grid USA filed registration  statements with the Commission under the Securities
Act of 1933, annual reports on Form 10-K,  quarterly reports on Form 10-Q, proxy
statements  and other  reports.  National Grid also reports to the Commission on
Form 20-F annually and on other forms periodically.

Under the Public Utility Holding Company Act of 1935 (the "Act"), in particular,
National Grid USA and Eastern Utilities  Associates  ("EUA") have recently filed
Annual  Reports on Form U5S and  extensive  disclosure on Form U-1 in connection
with NEES' merger with  National  Grid and EUA's merger with  National Grid USA.
These filings set forth much of the same information required by Form U5B.

National Grid also conducts  extensive foreign  businesses through National Grid
Holdings  Limited,  ("National Grid Holdings") an exempt foreign utility company
under the Act.  National  Grid Holdings  filed Form U-57 with the  Commission on
March 17, 2000, SEC File No. 073-00135.

In view of the extensive information on National Grid and National Grid USA made
available  through the numerous filings mentioned above and the exempt status of
National Grid  Holdings,  National Grid requests that the  Commission  waive the
requirements of Form U5B, as specifically  noted herein, and that the Commission
accept the  registration  statement as filed./1/ The  Commission  may grant this
request under Rule 20 (a) (3) under the Act. In addition, National Grid requests
authorisation to incorporate certain information by reference where indicated.

Unless  otherwise  noted, to the extent  possible,  the information  provided in
response to the Items and Exhibit  requirements of this Form will be as of March
31, 2000.

----------
/1/  The exceptions to the various  requirements of Form U5B for which waiver is
     sought  have been  addressed  with the  Commission  staff  prior to filing.
     National  Grid's filing notes next to each Item of the form where the staff
     has granted permission to omit or substitute information.

                                    BUSINESS

5(a) The  general  character  of the  business  done by the  registrant  and its
     subsidiaries,  separated as between the holding  companies,  public utility
     subsidiaries   (as  defined  in  the  Act)  and  the  various   non-utility
     subsidiaries.

A. Holding Companies

     National Grid is the top  registered  holding  company in the National Grid
system.  A chart depicting the overall  structure of the National Grid system is
attached  as Exhibit A.  National  Grid has no  operations  of its own but holds
investments  in both U.S. and foreign  companies.  National  Grid's  investments
outside the U.S. are held through  National  Grid  Holdings,  a private  limited
company  organised  under the laws of England and Wales,  and a foreign  utility
company  ("FUCO")  under the Act.  National  Grid's  U.S.  investments  are held
through a series of intermediate  registered  holding  companies  ("Intermediate
Companies")  which have no operations of their own. The  Intermediate  Companies
are:

     (a) National Grid (US) Holdings Limited
     (b) National Grid (US) Investments
     (c) National Grid (Ireland) 1 Limited
     (d) National Grid (Ireland) 2 Limited
     (e) National Grid General Partnership

     National Grid USA is a registered  holding  company  subsidiary of National
Grid General  Partnership.  National Grid USA, successor to NEES, has filed Form
U5S for the calendar  year 1999.  See SEC File No.  001-003446,  filed on May 2,
2000.  National Grid USA succeeds to the  registered  holding  company status of
NEES and, consequently, it is not a registrant on this Form U5B.

     The  Intermediate  Companies are organised under the laws of a member state
of the European Union with which the U.S. has a  comprehensive  Double  Taxation
Treaty  or a state  of the U.S.  The  Intermediate  Companies  are  directly  or
indirectly  wholly  owned  by  National  Grid  and  have no  public  or  private
institutional equity or debt holders. The Intermediate Companies are capitalised
with  equity  and/or  debt all of which is held by  either  National  Grid or an
Intermediate Company.

     The  Intermediate  Companies'  function in the  National  Grid system is to
implement a structure  that permits  National Grid to maximise the efficiency of
cross-border  ownership.  It is common  practice  for U.K.  based  multinational
corporations   to  hold  their  non-U.K.   subsidiaries   through  one  or  more
intermediary  companies  incorporated  under the laws of European  Union  member
states.  These types of transaction  structures are  implemented to minimise the
impact of tax on the repatriation of dividends and interest to the U.K./3/

----------
/3/  Exhibit J-2 to Form U-1, SEC File No.  70-9473,  explains the  functions of
     each  Intermediate  Company in more  detail and is  incorporated  herein by
     reference.

B. Public Utility Subsidiaries of National Grid USA

     The  public-utility  subsidiaries of National Grid USA were formerly public
utility  subsidiaries of NEES, a registered  holding company.  On April 19, 2000
subsequent to National  Grid's  acquisition of NEES,  National Grid USA acquired
EUA and its public utility and non-utility businesses.  On May 1, 2000 EUA filed
a Form U5S for the calendar  year 1999.  See SEC File No.  001-05366.  On May 1,
2000, EUA's public utility  subsidiary  companies were merged into National Grid
USA's public utility  subsidiaries.  By order dated April 14, 2000,  Holding Co.
Act Release No. 27166, the Commission found the combined National Grid USA / EUA
system to be integrated and the non-utility  businesses of EUA to be retainable.
The public utility subsidiaries of National Grid USA are as follows/4/

1. Massachusetts Electric Company ("Mass. Electric") is a public utility company

     The National Grid group also  operates a Sharesave  scheme and an executive
     share option scheme (the "Executive Scheme").

     The Sharesave scheme is savings related where, under normal  circumstances,
     share options are exercisable on completion of a three or five year save as
     you earn contract.  The exercise price of options granted represents 80% of

     relating to any  subsidiary of National  Grid Holdings is excluded,  except

     directors.  Options granted for the 1997/98,  1998/99 and 1999/00 financial
     years are subject to the  achievement  of performance  measures  related to
     earnings per share growth over a three year period.  The share  options are
     generally exercisable between the third and tenth anniversaries of the date
     of grant.

     In any ten year period the  maximum  number of shares that may be issued or
     issuable pursuant to the exercise of options under all of the National Grid
     group's  share  option   schemes  may  not  exceed  the  number  of  shares

     (1)  Proceedings  to enforce or to restrain  enforcement  of any order of a
          State commission or other governmental agency;

          Narragansett  has  appealed a RIPUC order  requiring  Narragansett  to
          refund customers  approximately  US$1.7 million which NEP has refunded
          to Narragansett  under its transmission  tariff.  Other parties to the
          suit are the RIDIV and The  Energy  Consortium  of Rhode  Island.  The
          action is pending before the Rhode Island Supreme Court.

     (2)  Proceedings  involving any franchise  claimed by any such company;  To
          the knowledge of National Grid's management there are none.

     (3)  Proceedings  between any such company and any holder,  in his capacity
          as such,  of any funded  indebtedness  or  capital  stock  issued,  or
          guaranteed  by such  company,  or  between  any such  company  and any
          officer thereof;  To the knowledge of National Grid's management there
          are none.

     (4)  Proceedings in which any such company sues in its capacity as owner of
          capital stock or funded indebtedness issued or guaranteed by any other
          company;  To the  knowledge of National  Grid's  management  there are
          none.

     (5)  Each other proceeding in which the matter in controversy, exclusive of
          interest  and  costs,  exceeds  an  amount  equal  to 2% of the  debit
          accounts shown on the most recent balance sheet of such company.

          (a)  From 1983 until 1998,  NEP was the wholesale  power  supplier for
               the Town of Norwood,  Massachusetts  ("Norwood").  In April 1998,
               Norwood began taking power from another  supplier.  Pursuant to a
               tariff  amendment  approved by the FERC in May 1998, NEP has been
               assessing Norwood a contract termination change ("CTC").  Through
               December  1999,  the  charges   assessed  to  Norwood  amount  to
               approximately  US$15 million,  all of which remain unpaid. NEP is
               pursuing a collection action in Massachusetts Superior Court.

               Separately,   Norwood  filed  suit  in  Federal   District  Court
               ("District  Court") in April 1997 alleging that NEP's divestiture
               violated  the terms of the 1983 power  contract  and  contravened
               antitrust  laws.  The District  Court  dismissed the lawsuit.  On
               appeal, the First Circuit Court of Appeals ("First Circuit") also
               consolidated  appeals Norwood made from FERC orders approving the
               divestiture,  the wholesale rate  settlement  between NEP and its
               distribution affiliates and the CTC tariff amendment. On February
               2, 2000, the First Circuit  dismissed  Norwood's  appeal from the
               FERC order and dismissed its appeal from all but one of Norwood's
               District   Court  claims,   which  relates  to  the  creation  of
               generation market power. On February 28, 2000, and March 3, 2000,
               respectively,  the First Circuit  denied  Norwood's  petition for
               further  review of its  District  Court  claims  decision and its
               decision on the FERC orders. On May 30, 2000,  Norwood petitioned
               the US Supreme Court for review of the First Circuit decisions.

<PAGE>

               Norwood  has also  appealed a 1999 FERC  decision  that  rejected
               Norwood's  challenge to the  calculation  of the CTC based on the
               term of the 1983 power contract.  On June 12, 2000, Norwood moved
               to amend its  complaint to reassert a claim for  rescission  with
               respect to NEP's divestiture. NEP has filed a motion to dismiss.

          (b)  Uses,  Inc., the  manufacturer of an energy savings  device,  has
               sued  Service  Company and the Rocky  Mountain  Institute,  d/b/a
               E-Source,  Inc.  (an  industry  trade  publication),  for product
               disparagement and tortious interference  resulting primarily from
               E-Source's  publication of an article  reviewing  Use's device in
               1997.  Uses  alleges  that  Service  Company  aided  and  abetted
               E-Source in these activities.  E-Source,  which has recently been
               acquired by  Financial  Times,  is the primary  defendant  in the
               case.  Uses claims damages of US$19 million.  The suit is pending
               in U.S. District Court for the District of Conneticut.
