Brooklyn, New York, November 16, 2004 - KeySpan Corporation (NYSE:KSE) announced

ownership interest in KeySpan Canada, once again demonstrating our commitment to
monetize our  non-core  assets and focus on growing our core  businesses,"  said

use the proceeds  from this  transaction  to initially  pay down debt to further

used to generate electricity;  potential write-down of our investment in natural
gas properties  when natural gas prices are depressed or if we have  significant
downward  revisions  in our  estimated  proved gas  reserves;  federal and state
regulatory  initiatives that increase competition,  threaten cost and investment
recovery and impact rate structure;  our ability to successfully reduce our cost
structures;  implementation of new accounting standards;  the degree to which we
develop unregulated  business ventures,  as well as federal and state regulatory
policies  affecting our ability to retain and operate those  business  ventures;
our  ability to identify  and make  complementary  acquisitions,  as well as the
successful  integration of those acquisitions;  inflationary trends and interest
rates; and risks detailed from time to time in reports and other documents filed
