Reconstruct terminal components

The Federal Aviation Administration (FAA), Western Pacific Region, awarded a $59.3 million Project Grant on September 9, 2025, to the County of Orange (John Wayne Airport) under the Airport Improvement Program (CFDA 20.106) to reconstruct and modernize electrical infrastructure across Terminals A, B, and C. The project encompasses replacement of aging switchgear, substations, microgrids, and backup power systems to enhance passenger and baggage movement operations. This grant funds a portion of the total project cost, with an associated Airport Improvement Program grant covering the remaining eligible expenses. The project is scheduled for completion by September 8, 2029.

The reconstruction initiative represents a critical infrastructure modernization effort serving the Santa Ana, California region. By upgrading the electrical distribution systems at John Wayne Airport, the project will improve operational efficiency and safety while supporting long-term economic benefits through enhanced transportation infrastructure. The County of Orange, a local government entity operating the airport since 2004, has demonstrated experience managing multiple FAA-funded infrastructure projects totaling over $100 million, including terminal rehabilitation, accessibility improvements, and equipment upgrades across the airport's facilities.
