The Central Plant at Oklahoma State University is a state-of-the-art facility designed to improve efficiency and reduce the university's environmental footprint. Located along Washington Street, the 73,000-square-foot facility was completed in April 2018 to replace the defunct Power Plant. It serves 10 million square feet across the OSU-Stillwater campus, providing steam for heating and chilled water for cooling. The Central Plant features advanced efficiency equipment, which is estimated to save more than $400,000 annually in energy costs. Additionally, the facility includes an 80-person classroom for interdisciplinary teaching and an observation deck for students and visitors to view the boiler and chiller floors.
