National Grid - sale of Manquehue net

National Grid Group plc announces today that it has reached agreement to sell its stake in its Chilean joint venture, Manquehue net.

As noted in the company's  pre-close  trading update issued earlier this week, we have also agreed the sale of Silica to management and
are in  advanced  discussions  to find a solution  for  Intelig  before the end of our  financial  year.  We remain  confident  we will
complete our exit from all these businesses within the financial provisions made last year.



Cautionary statement

This  announcement  contains certain  statements that are neither reported  financial results nor other historical  information.  These
statements are  forward-looking  statements  within the meaning of the  safe-harbour  provisions of the federal  securities laws of the
United  States.  These  forward-looking  statements  rely on a  number  of  assumptions  and are  subject  to a  number  of  risks  and
uncertainties,  many of which are outside the control of National Grid Group plc ("National Grid"),  that could cause actual results to
differ materially from those expressed in or implied by such statements, such as future market conditions,  currency fluctuations,  the
behaviour of other market  participants  and the actions of governmental  and state  regulators.  Other factors that could cause actual
results to differ  from those  described  in this  material  include the  ability to  integrate  Lattice  Group plc and  National  Grid
successfully  or to realise all of the synergies  from such  integration or the failure to retain key  management.  For a more detailed
description of these  assumptions,  risks and  uncertainties,  please see National Grid's filings with the United States Securities and
Exchange  Commission  (and, in particular,  the "Risk Factors" and "Operating and Financial  Review" sections in its most recent annual
report on Form 20F).  Recipients are cautioned not to place undue  reliance on these  forward-looking  statements,  which speak only as
