1.  I have reviewed this quarterly report on Form 10-Q of BayCorp
Holdings, Ltd;

2.  Based on my knowledge, this quarterly report does not contain
any  untrue  statement of a material fact  or  omit  to  state  a
material fact necessary to make the statements made, in light  of
the  circumstances  under which such statements  were  made,  not
misleading  with respect to the period covered by this  quarterly
report;

3.  Based  on my knowledge, the financial statements,  and  other
financial  information included in this quarterly report,  fairly
present in all material respects the financial condition, results
of  operations and cash flows of the registrant as of,  and  for,

4.   The  registrant's  other  certifying  officer  and   I   are
responsible for establishing and maintaining disclosure  controls
and  procedures (as defined in Exchange Act Rules  13a-15(e)  and
15d-15(e)) for the registrant and have:

  a)  designed such disclosure controls and procedures, or caused
such disclosure controls and procedures to be designed under  our
supervision, to ensure that material information relating to  the
registrant,  including  its consolidated  subsidiaries,  is  made
known  to us by others within those entities, particularly during
the period in which this quarterly report is being prepared;

  b)  [paragraph omitted pursuant to SEC Release Nos. 33-8238 and
34-47986];

  c)  evaluated the effectiveness of the registrant's  disclosure
controls  and  procedures and presented in this quarterly  report
our   conclusions  about  the  effectiveness  of  the  disclosure
controls  and procedures, as of the end of the period covered  by
this quarterly report based on such evaluation; and

  d)  disclosed  in  this  quarterly report  any  change  in  the
registrant's  internal  control  over  financial  reporting  that
occurred during the registrant's most recent fiscal quarter  that
has  materially affected, or is reasonably likely  to  materially
affect,   the   registrant's  internal  control  over   financial
reporting;

5.   The  registrant's  other  certifying  officer  and  I   have
disclosed,  based  on  our  most recent  evaluation  of  internal
control  over  financial reporting, to the registrant's  auditors
and  the  audit committee of registrant's board of directors  (or
person performing the equivalent functions):

  a)  all significant deficiencies and material weaknesses in the
design  or operation of internal control over financial reporting
which  are reasonably likely to adversely affect the registrant's
ability  to  record,  process,  summarize  and  report  financial
information; and

  b) any fraud, whether or not material, that involves management
or   other  employees  who  have  a  significant  role   in   the
registrant's internal controls.
