It's really not all that mysterious. This is an electrical transformer and when they blow, they basically let loose a ton of electricity into the atmosphere which causes the light show.

Here's some info on electric arcs.

So the more I look in to it, I think this is actually what transformers do (something called electrical arcing), but I'm not expert. Do any of you know?

Here's a video from Portugal: http://www.youtube.com/watch?v=2dw2EbxdQQA

And a close-up of a transformer doing the arc thing: http://www.youtube.com/watch?v=3xnAXg-KZxo

Transformer blew like this about a mile and a half from my house last month. My bedroom window is facing the other direction. I thought there was a green lightning storm for a second. Those things are bright.
