2 trillion watts /650000 amp = ~3500volts  Well within the range of believability...

" In situ measurements indicate that the interaction is additionally controlled by mass loading in the vicinity of Io [Goerm 1980; Saur at al., 1999; Russell and Huddleston, 2000], which drives strong parallel currents along the flux tubes of the associated Alfvenic disturbance [l'~bubauer, 1980; Belclzer at al., 1981]. Strongly field-aligned energetic electron beams toward and from Jupiter, possibly related to the footprint emission, were detected in the wake of the plasma flows past Io with Galileo [William at al., 1996; Franlc and Paterson, 1999] The power carried by the low energy electron beams was estimated on the order of 3x10^10 W. Crary [1997] proposed a model where the source of the infrared and FUV Io footprint is a precipitated electron beam accelerated by the wave's parallel electric field through a process of repeated Fermi accelerations. He predicted a total electron power precipitation of ~10" W with an average energy of about 80 k.eV. Claus! at al. [2005] recently suggested that the presence of high frequencylsmall scale waves observed by Galileo is a signature of filamentation of the Alfvén wings before they are reflected off the sharp boundary gradient of the Io torus. The resulting high frequencylsmall scale electromagnetic waves are able to accelerate electrons once they reach Jovian high latitudes."
