That wikipedia article is not enough to back your claim. As you can see, it lists a lot caveats. In my limited knowledge, electricity pricing is quite complicated, and those numbers are probably not even close to what business and industry are actually paying.

Edit: The blog-post is more convincing, but again, are those numbers really comparable? Maybe they are, I don't know enough about the subject, I just find it a little too simple to just compare numbers from different websites without deep knowledge of the topic.

Here's another link, the prices differ (?): http://epp.eurostat.ec.europa.eu/statistics_explained/index....
