My place here used to have an old electric hot water system that had an off peak electricity cycle connected to it - This has not been used for years as I have moved to gas hot water a while back

I got a letter in the mail today from the electricity distribution company advising that they plan to remove the meter in a few months unless I believe I still need this of which I need to call them.

Is there any good reason that I should keep the meter connected - e.g. other than hotwater off peak usage?
