Management of the Company carried out an evaluation, under the supervision and with the participation of DTE Energy’s Chief Executive Officer
(CEO) and Chief Financial Officer (CFO), of the effectiveness of the design and operation of the Company’s disclosure controls and procedures (as defined in
Exchange Act Rules 13a-15(e) and 15d-15(e)) as of December 31, 2014, which is the end of the period covered by this report. Based on this evaluation, the
Company’s CEO and CFO have concluded that such disclosure controls and procedures are effective in providing reasonable assurance that information
required to be disclosed by the Company in reports that it files or submits under the Exchange Act (i) is recorded, processed, summarized and reported within
the time periods specified in the SEC’s rules and forms and (ii) is accumulated and communicated to the Company’s management, including its CEO and
CFO, as appropriate to allow timely decisions regarding required disclosure. Due to the inherent limitations in the effectiveness of any disclosure controls
and procedures, management cannot provide absolute assurance that the objectives of its disclosure controls and procedures will be attained.

Management of the Company is responsible for establishing and maintaining adequate internal control over financial reporting as such term is defined
in Exchange Act Rules 13a-15(f) and 15d-15(f). Internal control over financial reporting is a process designed by, or under the supervision of, our CEO and
CFO, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in
accordance with generally accepted accounting principles.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any
evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree
of compliance with the policies or procedures may deteriorate.
Management of the Company has assessed the effectiveness of the Company’s internal control over financial reporting as of December 31, 2014. In
making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (2013 COSO) in
Internal Control - Integrated Framework. Based on this assessment, management concluded that, as of December 31, 2014, the Company’s internal control
over financial reporting was effective based on those criteria.
The effectiveness of the Company’s internal control over financial reporting as of December 31, 2014 has been audited by PricewaterhouseCoopers
LLP, an independent registered public accounting firm who also audited the Company’s financial statements, as stated in their report which appears herein.

There have been no changes in the Company’s internal control over financial reporting during the quarter ended December 31, 2014 that have
materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.
