New Endesa Electric and Gas Bills

Hi, I am considering moving to Almeria and am just simply confused about the electricity bills. The Endesa website is simply no help at all. I am creating this post in the hopes someone will share their actual utility bill so I can try to understand the mathematics they are using. Please remove any personal information, but I am trying to understand the billing only. And please a normal bill, not one with the Happy periods of free electricity. That is what is on the Endesa website which is not very helpful. Many thanks, John Murray
