DTE ENERGY EXPECTS ADDITIONAL SYNERGIES FOLLOWING MERGER WITH MCN ENERGY GROUP

         DETROIT - DTE Energy Co. (NYSE: DTE) today said that it expects to
realize additional cost synergies due to the recently completed merger with MCN
Energy Group. A higher-than-expected employee acceptance rate of voluntary early
retirement offers is expected to result in additional after-tax savings of about
$10 million to $15 million in 2001. The additional savings will coincide with a
one-time, after-tax restructuring charge.

         "As we embark on implementing the synergies derived from our merger, we
recognize that this is an extraordinary opportunity to move forward with the
transformation of DTE Energy into a premier regional energy powerhouse," said
Anthony F. Earley Jr., DTE Energy chairman and chief executive officer. "Not
only is our permanent cost structure lower as a result of the voluntary
departures, but we see significant developmental opportunities for our remaining
employees as we create new, more efficient internal work processes following the
departure of those availing themselves of the early retirement opportunity."

         In order to realize cost synergies from the merger, a total of 1,400
qualifying employees in overlapping functions were offered voluntary early
retirement packages. The offer was designed to reduce the combined work force,
which stands at 11,300. Due to an extended time frame for regulatory reviews,
and thus completion of the merger, a substantial number of additional employees
became eligible for the early retirement program, raising the one-time after-tax
restructuring charge from an expected $80 million to $100 million to about $170
million to $175 million.

         Earnings guidance for 2001, before merger restructuring costs and
goodwill amortization, was previously given at $3.50 to $3.60 per share and
remains unchanged. The one-time restructuring charge and seven months of
goodwill amortization will reduce reported earnings to $2.25 to $2.35 per share.

         Earley said the company would leverage the higher-than-expected early
retirement acceptance rate to capture additional synergies by improving work
processes that will reduce the need to hire replacement employees.
