Hard-wiring my Temporary power pole to my job site
If the electric panel, meter can and house wiring is complete, just have the electrical inspected and have the power company run the service. A electrician can run from a breaker on the temp power pole to the house electric, even if it's not all complete, but it would have to be inspected. Keep in mind that anyone could just shut off the breaker and there go your lights.
Note: This is/was allowed in Florida but you'd have to check with your local people.
