         On June 28, 2002, in accordance with the order of the Securities and Exchange Commission dated January 16, 2002, Holding Company Act Release No.
27490 (the "Order"), National Grid Group plc ("National Grid") submitted its report for the period October 1, 2001 to March 31, 2002  (the "June 2002
Report").   National Grid is filing this amendment to correct certain items contained in the June 2002 Report as discussed below.

         Common stockholders' funds for National Grid (US) Investments were overstated by $35.9M in the National Grid Group Capitalization Table (Exhibit A-3
to the June 2002 Report).  The corrected amount is $97.5M with total capitalization and the percentage split between Common stockholder's funds and
short-term debt for National Grid (US) Investments revised accordingly.  National Grid hereby amends the June 2002 Report as follows:.

          Exhibit A-3 of the June 2002 Report is hereby deleted and is replaced in its entirety by Exhibit A attached hereto.

         In this amendment a conversion ratio of 1 GBP to 1.42 US Dollars has been used.  The exchange rate conversion is provided solely for convenience and
should not be taken to mean that the pound sterling amounts have been, could have been, or could be converted to US Dollars at the rates indicated or at any
other rates.

                                                                     =====================


                                                                           SIGNATURE
