Where does the power come from that is needed to levitate a superconducting magnet against the constant pull of gravity?

In an aircraft in steady flight, lift exactly matches the pull of gravity. Generating that lift requires a continuous flow of power which is fed by the consumption of fuel. But a levitating supermagnet just sits there mid-air as long as it is kept cold enough. How?

(Yes, I know that a lot of a plane or helicopter's power is also used to overcome drag, thrown away as waste heat, accelerate, or to do other useful things. Let's set that aside for now.)

So far, everything said here has been wrong. There is no work done at all, no energy expended. A stone column holds up a statue against gravity mechanically without expending work. Here it's done magnetically. Both are static situation with no energy expenditure.
