Energy Bot was the most helpful comparison website I found. I didn't have to manually enter my monthly usage data (although I worry a bit about that info apparently being public and easily accessible to just anyone), and it did realistic month-to-month calculations, instead of just relying on average usage to recommend plans. Because of that, it came up with a much cheaper set of plans than the other sites based on my real electrical usage needs. And the calculations were right - I compared them to the output from my Python script that did the same calcs. So, overall, a very useful site. And it made picking and ordering an electric plan really easy - it took seconds from start to finish. So overall, I liked what I saw.
