The rates of Libor + 0.5% are directly comparable to National Grid Group plc’s own cost of external bank facilities of Libor +
0.425%.  This rate has been adjusted slightly to reflect that the loans are to Intermediate Holding companies whose credit strength
is less than the parent National Grid Group plc.  A loan issued by National Grid (US) Holdings Limited is at a margin of 1.75%.  This
is a continuation of an old loan at the same margins that were agreed to after consultation with Chase Manhattan.

Reporting Requirement No. 8: The amount and terms of any nonexempt financings consummated by any Nonutility Subsidiary during the reporting period.

Response: None

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

Reporting Requirement No. 9: A retained earnings analysis of each company in the National Grid USA system, detailing Gross Earnings (as that term is defined in the Commission’s Order dated March 15, 2000, National Grid Group plc, Holding Co. Act Release No. 27154) or income available for dividends, goodwill amortization, dividends paid out of each capital account, and the resulting capital account balances at the end of the reporting period.

     Response: Please see Exhibit A-2 attached hereto.

National Grid USA and its subsidiaries adopted Statement of Financial Accounting Standards No. 142 "Accounting for Goodwill and Other Intangible Assets" (FAS 142), effective April 1, 2001. FAS 142 requires that goodwill no longer be amortized and that it must be reviewed for impairment within six months of adoption ("transitional goodwill impairment test"), and annually thereafter.

The transitional goodwill impairment test compares the goodwill carrying value to its fair value. If the carrying value exceeds its fair value, goodwill is reduced to fair value by a goodwill impairment adjustment that must be completed by the end of the year of initial adoption.

In accordance with FAS 142, National Grid USA utilized a discounted cash flow approach incorporating its most recent business plan forecasts in the performance of the transitional test for goodwill impairment. The results of this analysis determined that no adjustment to the goodwill carrying value was required.

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


Reporting Requirement No. 10: A table showing, as of the end of the reporting period, the dollar and percentage components of the capital structures of National Grid, National Grid One, each Intermediate Holding Company, and each company in the National Grid USA system.

      Response:

For the National Grid USA system companies, please see Exhibit A-4 attached hereto.

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

Reporting Requirement No. 11: If any National Grid USA subsidiary borrows from an associated company on the FUCO side of the National Grid system, National Grid will: (a) list a minimum of three other sources of funds and their rates and terms; and (b) provide a cost/benefit rationale, consistent with the procedure described in the Application for determining available market rates, explaining why funding from the FUCO associate was the best option.

     Response:

There were no loans during the reporting period to National Grid USA subsidiaries from an associated company on the FUCO side.

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

Reporting Requirement No. 12: Identification of: (a) all entities established directly or indirectly by National Grid during the reporting period under the authorization granted by the Order ("New Entities"); (b) the business purpose(s) of those entities; (c) the significant assets held by those entities; and (d) the owner(s) of those entities, including the percentage of interests in those entities held by the owners.

     Response:

During the reporting period National Grid established no financing entities to facilitate financings by issuing to third parties income preferred securities or other authorized or exempt securities.

During the reporting period National Grid neither acquired nor established, directly or indirectly, any Intermediate Subsidiaries organized for the purpose of acquiring, financing and holding the securities of one or more existing or future Nonutility Subsidiaries.
