Stock Exchange Announcement- 7 January 2002

National Grid Shareholders approve Scheme of Arrangement
    -------------------------------------------------------

On 10 December 2001 National Grid Group plc ("National Grid")
announced that it had published a circular to its shareholders
(the "Circular") in connection with the introduction of a new
holding company for the group, New National Grid plc ("New
National Grid"), to be renamed National Grid Group plc, which
was to be effected by means of a scheme of arrangement (the
"Scheme") under section 425 of the Companies Act 1985.

The Directors of National Grid are now pleased to announce
that at today's Court Meeting, the shareholders of National
Grid duly approved the Scheme without modification. At the
subsequent EGM, also held earlier today, National Grid
shareholders duly passed all the resolutions which were
proposed, as set out in the notice of Scheme EGM dated 10
December 2001.

The Scheme is subject to final sanction by the Court and is
expected to become effective in early 2002 which is the same
time as the acquisition of Niagara Mohawk Holdings, Inc. is
expected to complete.

Terms defined in the Circular have the same meanings when used
in this announcement, unless the context requires otherwise.

Stock Exchange Announcement- 17 January 2002

National Grid Receives Securities and Exchange Commission
Approval for Niagara Mohawk Acquisition - Acquisition now
expected to close by end January

National Grid Group plc ("National Grid") announces that on 16
January it received approval from the US Securities and
Exchange Commission, under the Public Utility Holding Company
Act of 1935, for its acquisition of Niagara Mohawk Holdings,
Inc. (Niagara Mohawk).  This is the final regulatory approval
required to complete the acquisition. National Grid expects to
close the acquisition on 31 January 2002.

Roger Urwin, Chief Executive of National Grid Group said,
"Following the recent shareholder approval of the Scheme of
Arrangement, the SEC approval makes this an excellent start to
the New Year for National Grid. We can now look to implement
our integration plans and begin to deliver the benefits of the
Niagara Mohawk acquisition.

"National Grid's US strategy continues to transform the shape
and potential of the company. Niagara Mohawk will double the
size of our US business with more than 60 per cent of the
Group's electricity operating profits coming from the US. The
acquisition is expected to enhance earnings per share before
exceptional items and after goodwill amortisation in the first
full year after completion. We are confident that we will meet
our objective of earning a nominal pre-tax return of 10.5 per
cent on our expanded US business by the year ending March
2005, underpinning our target to increase dividends per share
by five per cent per annum in real terms up to 2006."

In accordance with the terms of the Merger Agreement, Niagara
Mohawk shareholders will receive consideration of 18.89
dollars for each share of Niagara Mohawk common stock held,
valuing the equity of Niagara Mohawk at 3.0 billion dollars
(2.1 billion pounds sterling). The per share consideration was
determined by the average US dollar price of five National
Grid Ordinary shares being 32.22 dollars as calculated from 20
trading days randomly selected from the 40 consecutive trading
day period 13 November 2001 to 10 January 2002.  As the
average price is below the bottom of the range of 32.50
dollars to 51.00 dollars specified in the Merger Agreement,
the base 19.00 dollars consideration per Niagara Mohawk share
has been reduced by two-thirds of the percentage decrease
below 32.50 dollars.


Niagara Mohawk shareholders can elect to receive their
consideration in the form of 18.89 dollars cash per share,
0.5863 National Grid American Depositary Shares per share, or
a combination of both.

The Merger Agreement states that the total amount of cash
payable to Niagara Mohawk shareholders will be 1.015 billion
dollars, but National Grid will increase this amount to 50 per
cent of the total consideration, if it receives sufficient
cash elections. National Grid will, so far as possible,
satisfy Niagara Mohawk shareholders' elections. However, to
the extent that they cannot be satisfied in full they will be
scaled down on a pro rata basis.

The deadline for Niagara Mohawk shareholders to return their
forms of election to the Exchange Agent, The Bank of New York,
is 5:00 pm (New York time) on 24 January 2002.  Election
materials and delivery instructions were mailed to Niagara
Mohawk shareholders on 27 December 2001. Niagara Mohawk
shareholders who did not receive that mailing should contact
the information agent for this transaction, Mellon Investor
Services, on 1 800 953 2703 as soon as possible. Mailing and
delivery instructions are also available on the companies'
websites at www.nationalgrid.com and www.niagaramohawk.com.

Stock Exchange Announcement- 28 January

National Grid Announces Preliminary Merger Election Results

On 17 January 2002 National Grid Group plc ("National Grid") announced
that, in accordance with the Merger Agreement governing the terms of the
acquisition of Niagara Mohawk Holdings, Inc. ("Niagara Mohawk"), Niagara
Mohawk shareholders will receive consideration of 18.89 dollars for each
share of Niagara Mohawk common stock held, which they could elect to
receive in the form of 18.89 dollars cash per share, 0.5863 National
Grid American Depositary Shares ("ADSs") per share or a combination of
both.

Under the Merger Agreement, the aggregate cash consideration offered to
all Niagara Mohawk shareholders was 1.015 billion dollars.  However, the
Merger Agreement allows National Grid, at its sole discretion, to
increase the cash component of the total consideration if cash elections
received from all Niagara Mohawk shareholders exceed 1.015 billion
dollars.

The Election Deadline was 5:00 p.m. (New York time) on Thursday, 24
January 2002.  National Grid has been advised that the preliminary

STOCK EXCHANGE ANNOUNCEMENT- 29 JANUARY 2002

NATIONAL GRID ANNOUNCES FINAL ELECTION RESULTS AND ALLOCATION
OF CONSIDERATION

On 17 January 2002 National Grid Group plc ("National Grid")
announced that, in accordance with the Merger Agreement
governing the terms of the acquisition of Niagara Mohawk
Holdings, Inc. ("Niagara Mohawk"), Niagara Mohawk shareholders
will receive consideration of 18.89 dollars for each share of
Niagara Mohawk common stock held, which they could elect to
receive in the form of $18.89 cash per share, 0.5863 National
Grid American Depositary Shares ("ADSs") per share or a
combination of both.

The deadline for Niagara Mohawk shareholders to make their
elections expired on 24 January 2002 and the deadline for
delivery of Niagara Mohawk shares under the guarantee of
delivery mechanism expired on 28 January 2002.  At the expiry
of this deadline, valid elections were received representing
approximately 140.6 million Niagara Mohawk shares or 88 per
cent of the 160.2 million shares outstanding.  Of these
shares, approximately 65.2 million shares (46 per cent of the
electing shares) elected for cash consideration, and
approximately 75.4 million shares (54 per cent of the electing
shares) elected for ADS consideration.  The remaining Niagara
Mohawk shares, approximately 19.6 million or 12 per cent of
the total shares outstanding, were recorded as non-electing
shares.

Under the Merger Agreement, the aggregate cash consideration
offered to all Niagara Mohawk shareholders was 1.015 billion
dollars.  However, the Merger Agreement allows National Grid,
at its sole discretion, to increase the cash component of the
total consideration if cash elections received from all
Niagara Mohawk shareholders exceed 1.015 billion dollars.
Given that the cash elections exceeded this level, National
Grid has increased the aggregate cash component of the
consideration to ensure that all valid cash elections are
satisfied in full.  Niagara Mohawk shareholders who elected
cash for some or all of their shares will therefore receive
18.89 dollars cash per share, representing 1.23 billion
dollars in aggregate.

Similarly, all valid ADS elections will be satisfied in full.
Niagara Mohawk shareholders who elected ADSs for some or all
of their shares will receive their consideration in the form
of National Grid ADSs based on an exchange ratio of 0.5863
National Grid ADSs per Niagara Mohawk share.

Holders of Niagara Mohawk shares who did not make a valid
election will receive 0.5863 National Grid ADSs for each
Niagara Mohawk share held.

In aggregate, the consideration for the acquisition will be
allocated 41 per cent to cash and 59 per cent to ADSs.  The
total number of ADSs issued for the acquisition is
approximately 56 million, representing approximately 279
million ordinary shares.  This represents approximately 16 per
cent of the enlarged share capital.

As provided for in the Merger Agreement, National Grid will
not issue any fractional ADSs.  Niagara Mohawk shareholders
entitled to a fractional ADS will receive a cash payment based
on the fractional interest held and the closing price for a
National Grid ADS as reported on the New York Stock Exchange
on the date the acquisition is completed.

Roger Urwin, National Grid Group Chief Executive, said, "We
are pleased that we have been able to meet all valid elections
as submitted.  This is an excellent transaction for
shareholders which will immediately enhance earnings per share
after goodwill amortisation and before exceptional items."

National Grid expects to complete the acquisition of Niagara
Mohawk on 31 January 2002.  It is expected that dealings in
the National Grid ADSs issued pursuant to the acquisition will
commence on the New York Stock Exchange under the symbol "NGG"
at 9.30 a.m. (New York time) on 1 February 2002.

The Bank of New York, as exchange agent, will commence
distributing the consideration to Niagara Mohawk shareholders
who made valid elections in the form of cheques or direct
registration advice forms no later than 6 February 2002.
Niagara Mohawk shareholders who did not make a valid election
will be sent instructions on how to claim their consideration
on or about 14 February 2002.
