Central Utility Plant
Background
Construction of the Central Utility Plant began in September 2009 as a part of the Airport Improvement Program. The Central Utility Plant is a design-build project which will allow contractors to both design and construct the facility. The design-build contracting model generally results in time and cost savings when compared with traditional design-bid-build procurement.
When complete, the Central Utility Plant will supply the Thomas F. Riley Terminal complex with power and with chilled water to serve the air conditioning system. The Central Utility Plant will include water chillers, cooling towers, heat exchangers, and four natural gas-fired internal combustion engines for electric generation, as well as additional auxiliary mechanical equipment to support the production of chilled water for the air conditioning system.
Because the site is visible to the public, the Airport plans to use landscaping to screen the building and related outdoor equipment. As part of the landscape plan, all existing healthy palm trees at the building site will be reused. The Central Utility Plant is equipped with a state-of-the-art emission control system and complies with South Coast Air Quality Management District (SCAQMD) regulations. Completion of the Central Utility Plant Project is set for December 31, 2010. Below is a conceptual view of the completed project.
Power Generation Support
With the Central Utility Plant in place, John Wayne Airport will continue to purchase 5% of its power supply from Southern California Edison Company (SCE) via a 12kV feed. The Airport will also continue to rely on SCE as a secondary source for its power needs; SCE will be on standby to supply John Wayne Airport with power if the Central Utility Plant service is interrupted for any reason.
Air Conditioning System Support
The Central Utility Plant will be equipped with waste heat recovery equipment associated with the natural gas engine generators. The recovered waste heat will be utilized to generate 900 ton refrigeration capacity which satisfies most of the Airport’s needs of the chilled water year-round. The Central Utility Plant is also equipped with electric operated water chillers to help satisfy the Airport’s chilled water demand.
Budget
The Central Plant Project is estimated to cost $27.7 million. The project is being funded by Airport revenues.
