Are they able to do this,
They are already doing it which would indicate that they are, indeed, "able" to do it.

or do I have any recourse?
No. Your lease says leave the utilities on. You signed the lease.

It doesn't seem fair that I should pay for the management's use of my electricity.
Fair is where you go on rides and eat cotton candy. Has nothing to do with your contractual obligations.

Do I have any rights after surrendering the apartment if my lease isn't up yet and I have paid through the end of my term?
Probably not.
