In year 2005, GE Locomotive Indonesia introduced a brand new locomotive with full computer control.
It was given type as C20EMP and still uses the 7FDL-8 engine.
The overall shape is similar to other Indonesian CC 203s, but has a Brightstar Sirius on-board computer to control the propulsion and transmission, for better fuel economy and lifetime.
The power rating is 2150 HP but the power output is 1950 HP.
Because the result is very good, PT Kereta Api Indonesia, made a contract with PT Industri Kereta Api Indonesia (PT INKA) to build 20 locomotives.
 Then, the brand-new C20EMP was delivered from GE and assembled at PT Industri Kereta Api Indonesia (PT INKA).
These C20EMP numbered as CC 204 08-xx will be numbered as CC 204 12-17.
CC204 08-09 was delivered at 2008, CC204 10-11 was delivered at 2009.
A total of 30 locomotives were manufactured before production ended in 2011.
While in Java, C20EMPs (CC 204) were mostly pulling Argo class trains and other executive class trains alongside the CC 203.
All CC204s are used for hauling coal trains and passenger trains in South Sumatra, replaced by CC206 (CM20EMP) in Java.
