You have to copy all the templates associated with the Template:Power Grid in order for it to work.

If you look at the edit source, you see that the Template:Graph/Horizontal Bar is used within the Power Grid template; so you would have to copy that over also.

It should work now, as I've gone ahead and created the other template on your wiki..
