Our meters have a display (LCD) that cycles between various readings, and one of them is instantaneous demand. It would depend on the model you have.
We've got the Itron brand meter. I can't go out and stare at it because it's raining and I don't want to get wet, but it does have several dsiplays that automatically scroll. Instantaneous demand isn't one of them, IIRC (going by memomory here). I've visited the MfR's web site but not lately.
Our data is sent back to the power board through fiber, the same fiber on which the "smart grid" (also known as "automatic sectionalizing system" in the old days) and my high-speed internet communicates. We're supposed to have online availability of a much greater amount of information soon, but it isn't available yet.
