Narrative:

Aircraft was being repositioned to a remote parking facility due to two mechanical issues taking up gate space. Flight crew agreed to taxi the aircraft to avoid having to reposition the aircraft under tow. Due to the extreme weather conditions; the entire ramp area was covered in a sheet of ice. The city pretreated the area; however; due to the weather conditions; heavy ice and snow; the aircraft was unable to park [in the original spot]. The aircraft was parked [nearby] instead. The apron does not have a safety envelope or aircraft type markings. It is simply a lead in line ending in a T to park the aircraft on.as the aircraft was being marshaled in; the plane was moving at a very slow pace. While applying the brakes the plane slide forward and to the left after being given the signal to stop. The plane slid into the ground power unit and pushed forward into a large embankment of snow. The pilot upon realizing the situation hit the reverse thrusters to go backwards. The ground power unit; a parking chock; ice and snow were pulled into the engine at that time. The ground crew was forced to jump out of the way to avoid major injury or even death.
