PLYMOUTH -- Midway through the second period, the lights in Plymouth's Compuware Arena flickered and dimmed, resulting in a 13-minute delay.

Those prone to pun could argue the Flint Powers Catholic hockey team had just shot the lights out. The Chargers were fresh off of scoring two goals in a 32-second span, putting Chelsea High School in a 3-0 hole.

And Chelsea didn't have a comeback in them this time, ending its postseason run with a 4-0 loss in the Division 3 state semifinals on Friday afternoon.

Powers moves on to face Bloomfield Hills Cranbrook-Kingswood, a 4-1 winner over Calumet, in the state finals on Saturday.

"We came out in the second period and I thought we were rattled," said Chelsea coach Don Wright, whose team was outshot 30-9. "When the lights went out, I said, OK, this is a good thing to kind of settle us down ... Unfortunately, after we came back we took three straight penalties and it didn't allow us to get into any type of a rhythm."

Chelsea, making its first ever semifinals appearance, was put on its heels at 3 minutes, 43 seconds of the first when Flint Powers' Nik Keene fired a slapshot from 20 feet out on Chelsea goalie Matt Dar. The puck richocheted off Darr's glove and into the net, putting the Chargers up 1-0.

Powers nearly added to its count in the final minutes of the first period, but Darr, who finished with 26 saves, made a slew of impressive stops, including a stretching stick-deflection in the final seconds. With the shot count at 11-4 in Powers' favor, Chelsea had to feel fortunate to be down only one.

"We knew that they were going to be a tough defense," said Chelsea senior forward Dan Hudson, whose team lost to Powers, 5-2, earlier this season. "Our plan was just to get pucks to the net, and have guys going in after rebounds. That's how we've been scoring goals throughout this playoff run.

"Unfortunately, we couldn't get them as well as we wanted to."

Meanwhile, the Chargers took just a shade over three minutes in the second period to widen the gap to 3-0, netting goals at 12:17 and 11:45.

"That was one of the best stretches we've played all year," said Powers coach Travis Perry, referring to the opening minutes of the second. "Once we settled in, we were able to take control."

And the soon following light shortage that stopped play for 13 minutes didn't slow down Powers (24-2-3), which added to its count with 4:03 left to make it 4-0. At period's end, Chelsea -- stuck in a 10 minute shot-less streak -- had only one shot to show for.

The Bulldogs managed four further shots in the fourth, including a one-timer by Hudson at seven minutes, but none of them found the back of the net.

Leading Flint Powers on offense were Keene, Andy Lay and Niles Owen, who had one goal and one assist apiece.

Chelsea ends its season with a 14-13-2 overall record.

"The record doesn't show it, but it's a great season, I think," said Hudson. "One of the team goals we set was to win the regional finals and we did that."

Added Wright, "I told the guys in the locker room that their heads need to be up. I know we would've liked to play better today -- that's not to take anything away from Flint Powers.

"It wasn't our game, but I'm really proud of them."
