SES-12 as Eutelsat 172B will be built around the Eurostar E3000 platform Airbus Space, in its latest evolution EOR ( Electric Orbit Raising ). It uses only electric propulsion to transfer the satellite to the geostationary orbit and for all his maneuvers orbitals .
For motorized, Space Airbus has chosen the plasma propulsion technology only able to push a satellite the size and mass of ITS-12 effectively. Designated Hall effect , it is to create a magnetic field to trap electrons and allow the formation of a region of high electric field . Thrust is then ensured by extracting and accelerating ions from the positive plasma high density. http://enjoycoloring.com/tag/funny/ Airbus is the first company in the world to do so.

This choice differs from Boeing uses propellants gate, also called ion engines (which eject electrons). If successful for station keeping, this type of propulsion induced pushed too just for ramming satellite SES-size equivalent to 12. It is suitable only for smaller.
