MPSC approves DTE Electric $65 million rate increase

LANSING, Mich. – The Michigan Public Service Commission (MPSC) today authorized DTE Electric Co. to increase its rates by $65,239,000 effective May 1.

The total is 28 percent of the $231 million DTE sought when it filed its rate case in April 2017 (Case No. U-18255), and are 1.4 percent higher than rates set in its last rate case.

In November, the Detroit-based utility self-implemented a rate increase of $125 million, which it was legally allowed to do, as it awaited a decision by the MPSC on its rate case. Since the total approved today is just over half of the amount that was self-implemented, DTE will file a separate case to determine how much is refunded to customers.

New energy laws that went into effect in April 2017 abolished the self-implementation option for utilities and DTE’s is the last rate case of any utility where the practice is allowed.

"It's important that DTE Electric customers have a reliable electrical grid so they can be confident power is available when it's needed," said Sally Talberg, chairman of the MPSC. "The Commission believes it is vital that utilities are committed to upgrading infrastructure to promote safety, provide reliable service and reduce customer outages."

Infrastructure spending was approved in several areas to improve electric infrastructure and reliability for customers. DTE will spend on distribution operation and maintenance, including tree trimming; pole top maintenance; substation and station improvements; and system upgrades to prevent problems associated with potentially overloaded equipment as part of the Gordie Howe International Bridge development project in Detroit.

The company’s previous rate increase of more than $184.3 million was approved in January 2017 (Case No. U-18014).

The Commission decided to address the impact of the federal tax law changes in a separate proceeding (Case No. U-18494), which will begin in 30 days.
