Earth Hour is tomorrow evening.  The event is organized each year to promote and support energy conservation efforts.  Participants turn off their lights for one hour to mark the event.  In celebration of Earth Hour, we’re taking a look at some power outages that have taken place in NHL history.

And we’re talking about actual power outages here, not teams that can’t score goals with the man advantage.

In March of 2006, a game between the Pittsburgh Penguins and the Toronto Maple Leafs was delayed twice as the lights at the old Igloo just couldn’t stay on.  The screen at center ice still had power though and the Penguins organization took this opportunity to air a video that outlined their plans to fund and build a new hockey arena in Pittsburgh.  The fans agreed, chanting “NEW ARENA” throughout the blackout.

Unfortunately, when the team did get their new arena (the CONSOL Energy Center) there were still issues with keeping the lights on.  The lighting system malfunctioned twice in one week back in February.

At least the Penguins were able to continue those games eventually.  A Tampa Bay Lightning visit to the Prudential Center in New Jersey was cut short in January 2010 when half of the arena’s lights went out.  The game, which originally started on Friday January 8, 2010 was stopped in the second period due to a lighting problem.

After a 1 hour and 42 minute delay, the game was postponed.  It was rescheduled for Sunday January 10th.  The Lightning, who were leading 3-0 when the game stopped, ended up winning 4-2 after the game resumed two days later.

That wasn’t the first time the Devils had to deal with a lighting issue.

In the 2006 playoffs, the lights went out at the RBC Center during a game between the New Jersey Devils and the Carolina Hurricanes.   They came back on quite quickly though, but then the Hurricanes turned off the lights again, this time on the Devils’ season as they eliminated them from the playoffs.

Of course, the most famous hockey blackout took place during the 1988 Stanley Cup Final.

It was game four of the 1988 Final and the Oilers were leading the series 3-0. Boston was trying to fight off the sweep and the score was 3-3 in the second period.  Then the lights went out.  Boston Garden went dark and eventually the game was cancelled.   It was rescheduled for two days later and the game was played in Edmonton rather than Boston. The Oilers won the game 6-3 and were awarded the Stanley Cup on home ice.

This video shows the fog that delayed the game earlier and makes the whole situation seem very creepy:
