UCI Health Opens Nation’s Largest All‑Electric Hospital in Irvine

The seven-story, 144-bed facility completes a $1.3 billion campus, operating on electricity with a code‑required diesel backup.

Overview

  • The hospital opened on Dec. 10 and began receiving patients immediately, with the first emergency patient arriving at 7:52 a.m.
  • The 350,000-square-foot acute care facility is the sixth hospital in UCI Health’s 1,461-bed academic system.
  • Patient rooms, clinical equipment, and the kitchen run on electricity sourced from on-site solar and water-driven systems with no natural gas use.
  • Diesel generators remain on site solely to provide life-safety power during outages, as required by regulations.
  • UCI Health says the project finished in just over four years and is expected to create about 1,000 health care jobs.
