Electricity Supply

Hi All, I am setting up a coffee van in a private car park. I have all permission etc. The only thing i need to do is supply my own electricity. In order to do this, do i request ESB to do this (as it will have to be metered) or is there another way. Presumably they will take from a close by supply. Ideally the electricity plugs would be on a post and i would have a key to access it every time i need it. Any positive help in this regard would be most welcomed on how to go about doing this. P.S. I am not talking about a e-car charge point. I am talking about actual electrical supply to run the equipment needed to serve coffee. Thanks
