Hugh, to get a well informed opinion, please do a little more informing. How do they want to charge you? by the KWHR? and if so, how are they figuring it? Very well could be that there is a misunderstanding of intentions here and people are calling something one thing when they meant another if they knew what they were talking about in the first place. Because depending on how you are doing the math, charging for 600 amps and 200 amps may be the same thing. This whole thing just sounds a little too wierd.
