NIGP 72019: Compressors, Compressed Natural Gas (CNG)

NIGP 72019 Compressors, Compressed Natural Gas (CNG), an Item code, covers stationary and mobile CNG compression and fueling equipment that state and local governments procure for fleet operations, public refueling stations, and energy recovery projects. Recent solicitations reveal procurement across repair and maintenance contracts for existing compressor infrastructure, new compressor unit acquisition with installation and commissioning, and advanced applications including renewable natural gas attribution and digester gas utilization projects. Issuing bodies span transit authorities, municipal utilities and water districts, county governments, school systems, and city infrastructure departments. The City of Palo Alto, Long Beach Public Utilities Department, DeKalb County in Georgia, and the Eastern Municipal Water District in California represent repeat or standout buyers of CNG compressor services and equipment. Scope extends from routine preventive maintenance and emergency repair services with specified response times, to turnkey procurement of compressor units with warranty coverage and on-site training, to complex energy recovery and RNG revenue-sharing arrangements involving RIN credit management and multi-year design-build-finance-operate contracts.

Geographic activity concentrates in California (Palo Alto, Long Beach, Eastern Municipal Water District in Riverside County, and Albuquerque-area transit operations), Georgia (DeKalb County), Kansas (City of Olathe), and Arizona (City of Tucson).
