Cosumnes Power Plant

CLIENT: Sacramento Municipal Utility District
LOCATION: Sacramento, CA

The Cosumnes Power Plant (CPP) is located on a 30-acre site a half-mile south of the now closed Rancho Seco Plant in southeastern Sacramento County. The Project will be completed in two phases of 500 megawatts each. SMUD brought Phase 1 online in 2006.

SMUD contracted with IEC to provide Owner’s Engineering services. The work began as a small contract and quickly expanded into a multiple-year commitment for project coordination, owner’s engineering, Chief Building Official services, and construction management services. IEC provided the licensing project manager, environmental specialist, structural, mechanical and electrical engineers, and a variety of subcontractor specialties, such as geotechnical services and pipeline inspection services. IEC also coordinated licensing, environmental documentation, mitigation planning, and the preliminary engineering layout for the plant, switchyard, and linear facilities.

IEC managed subcontractors, provided technical guidance and leadership to craft labor, managed project priorities and schedule, and coordinated work with other disciplines. Our personnel worked with the CPP quality control team to ensure compliance with the latest codes, specifications, permit conditions, and accepted practices. IEC personnel also assisted the startup lead contractor with commissioning activities throughout the facility as systems were brought online.

The numerous assigned tasks were a direct result of IEC’s commitment to providing the best people for the job, both IEC employees and specialty subcontractors alike.
