Exhibit 31.2

# CERTIFICATION PURSUANT
TO 
18 U.S.C. SECTION 1350, 
AS ADOPTED PURSUANT TO SECTION
302 
OF THE SARBANES-OXLEY
ACT OF 2002

I, Bertrand A. Valdman, certify that:

I have reviewed this quarterly report
on Form 10-Q of Puget Energy;

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;

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, the periods presented in this quarterly report;

The registrants other
certifying officer(s) 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)    
          Evaluated the effectiveness of the registrants disclosure controls and
          procedures and presented in this report our conclusions about the effectiveness
          of the disclosure controls and procedures, as of the end of the period covered
          by this report based on such evaluation; and

c)    
          Disclosed in this report any change in the registrants internal control
          over financial reporting that occurred during the registrants most recent
          fiscal quarter (the registrants fourth fiscal quarter in the case of an
          annual report) that has materially affected, or is reasonably likely to
          materially affect, the registrants internal control over financial
          reporting; and

The registrants other
certifying officer(s) 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 persons 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 control over
          financial reporting.
