History
CEN was named after Cerro Centinela, the Spanish name for Mount Signal which straddles the U.S.-Mexico border. The prison opened in October 1993, approximately 22 months after Calipatria State Prison located approximately 40 mi north.

A 1994 statute "require[d] the U.S. attorney general either to agree to compensate a state for incarcerating an illegal immigrant or to take the undocumented criminal into federal custody." In January 1996, the administration of Governor Pete Wilson "tested the law" by asking Immigration and Naturalization Service agents "to take custody of a 25-year-old illegal immigrant serving time in Centinela State Prison for drug offenses"; however, the agents refused. Therefore, in March 1996 Wilson sued the federal government to enforce the 1994 law.

As of 1997, CEN was the "most overcrowded prison in the state" as it ran at "259 percent of designed capacity." By 2007, however, Avenal State Prison was the California state prison system's "most overcrowded facility."

In August 2006, a quadriplegic inmate died after the air conditioning failed in a van carrying him and another inmate from California Substance Abuse Treatment Facility and State Prison, Corcoran to CEN. According to a reporter's summary of statements by "the federal official now in control of medical care in the state's prison system," the death was "proof of a broken system"; according to the reporter's summary of statements by representatives of the California Department of Corrections and Rehabilitation, the death was "a terrible event caused by happenstance."
