The governing FIA announced on Friday that Red Bull had changed the MGU-K (kinetic motor generator unit), energy store and control electronics on his car.
All the changes breach the regulations governing how many elements a driver can use during a season and trigger automatic penalties.
Ricciardo had recognised on Thursday that he faced a big drop but was optimistic he would be able to limit the damage at a circuit with plenty of overtaking possibilities.
The Australian has won two races this year and is fourth overall in the championship but 65 points behind Ferrari's leader Sebastian Vettel at the halfway point.
