                                  Board Change



National Grid plc (the 'Group') today announces that Mike Jesanis, currently
Group Director responsible for US distribution, will be leaving the Group at the
end of the year (31 December 2006). This announcement comes ahead of the Group
finalising its future operating structure following its announcement earlier
this year to acquire KeySpan.


Mike joined New England Electric System ('NEES') in 1983 and has been part of
National Grid since the Group acquired NEES, its entry point into the North East
US, in 2000.


Sir John Parker, Chairman of National Grid, paid tribute to Mike's contribution
to the Group: 'Mike has been an important part of the establishment and growth
of our highly successful US business. He leaves with our business in very good
shape for the next big stage of its development as we move towards completion of
the KeySpan acquisition. All of us wish Mike very well in the future.'
