Powershop have increased the referral back up to $150 until April 30'th this month.
I got signed up from OzBargain myself here maybe 5 years ago and I've been pretty happy with the serivce, it works well and prices have been good, I've also twice now, had other OzB members sign up with my code and gotten me a bonus $150 in credit.
Furthermore, you can 'pre-buy' power, allowing you to gain pretty steep discounts based on your usage.
Here's a link to choice, to see if you'd be happy with them, since I can't link my code!

Hope I've done this right, don't submit often!
Note: The friend who signs up will receive their $150 credit in four instalments across their first year (The first day, 3 months, 6 months and 9 months the retailer starts selling energy to them).
Hope I've done this right. By the way the $150 I mention in the post, is 2x$75 credit, when it was $75 that particular month.
