Thinking in terms of Nicaragua

I was watching the Under-20 World Cup with my host brother last night and I noticed that the field was really well-lit, but I couldn't help wondering what they would do if the power went out. Would they have that many generators for the entire field? Would they stop playing? Would all of the players get headlamps? Then I realized that the game was in Canada. The lights don't go out in Canada like they do here :(.
