Two DTE transformers at Central Power Plant to be shut down this weekend

DTE Energy will shut down two of the three transformers at the Central Power Plant (CPP) from 2 p.m. Saturday until 4 a.m. Sunday, which will mean a higher risk of electric power interruptions for the Central, Medical, and South campuses during the hours they are out of service.

One DTE transformer and CPP generation will provide power for the campus during the 14 hours that Transformers No. 1 and No. 3 both are expected to be shut down.

Utilities and Plant Engineering — Electrical Operations and Engineering Office of Plant Operations asks that unnecessary electrical equipment be turned off today for this weekend. It is advised that important information be backed up, and discretion should be used in work relating to critical research this weekend.

Although no interruption of power is expected, precautionary measures have been taken to enable an increase in generation at the CPP, and Building Automation Systems will be assisting to decrease electrical cooling loads for this weekend if necessary.

The details are as follows:

DTE has scheduled a shutdown of Transformer No. 1 at the CPP to repair cables on multiple trunk lines feeding the university on Saturday and Sunday. The utility has scheduled a shutdown of Transformer No. 3 at the CPP to repair cable on trunk line 5509 feeding the university from Saturday through April 27.

The shutdown will begin at 2 p.m. Saturday. Transformer No. 1 is estimated to be down until 4 a.m. Sunday. Transformer No. 3 will not be back in service until April 27.

DTE service to U-M is expected to be back to normal on Sunday.
