Entergy Resources Inc. selected FVB Energy Inc. to provide a variety of business development, marketing and engineering services for this district energy system, which provides cooling and heating services to five large medical complexes as well as government and commercial buildings in downtown New Orleans. The system began operations in 2000.
• District cooling. The plant will have an ultimate capacity of 32,000 tons including thermal energy storage. The plant combines large packaged electric centrifugal chillers producing 37°F water with four dual-duty, industrial grade screw chillers capable of producing chilled water or ice for thermal energy storage.
• Ice thermal energy storage. Peak power demand load shifting is provided with 52,600 ton-hours of ice-on-coil thermal storage in a 900,000 gallon tank.
• District heating. Multiple linked plants provide sufficient capacity to reliably supply 150,000 pounds per hour of 250 psig steam for space heating, domestic hot water, kitchen and sterilization.
• Standby/peak shaving power generation. Reliability is enhanced with 8 MW of diesel power generation for standby and peak shaving.
• Plant integrated with parking facility. District energy facilities are integrated into a site development plan that includes a 600-space parking garage.
• Five medical centers (Louisiana State University Medical School, Tulane Medical School and Clinic, Charity Hospital, VA Medical Center and University Hospital)
• Commercial buildings
• Government buildings
