While more than half of the more than 100,000 DTE Energy customers who lost power in southeast Michigan during Thursday's thunderstorms have had their power restored, many others still face the prospect of going into the weekend with no electricity.

Some of those families, like the McIsaacs and Mackses in Bloomfield Township, are preparing for graduation parties.

Sharon McIsaac said preparing for a party for 100 people for her daughter's high school graduation party is a challenge without electricity.

"Trying to get ready and cook and prepare and clean and stuff like that has been a little hard," McIsaac said.

To compensate for no working oven, Sharon McIsaac spent part of Friday cooking on a grill.

Her home has a generator, but it does not provide enough power to get everything done.

"Silly little things like being able to plug in the vacuum cleaner and actually vacuum my carpet before everyone comes, silly stuff like that," McIsaac said.

Lisa Macks lives in the same neighborhood and is in the same boat.  She is preparing for a graduation party Saturday for her son.  She said the party will go on, one way or another.

"Yes, we're just going to do it. I mean we'd have to call all those people and somehow it will work out, right?  That's what I'm hoping," Macks said.

The families were told Friday the earliest they would have power restored would be around midnight. They continue to prepare for their parties with their fingers crossed.
