AMEREN INFRASTRUCTURE UPGRADES

PARIC lead construction of a comprehensive infrastructure upgrade for Ameren’s 750,000 sq. ft. main campus. The project consisted of two new precast switchgear buildings, new primary and secondary electrical switchgear, new feeder conduits and wire, transformers, three new 1000kW generators, and a new 15,000-gallon generator fuel tank with precast containment building.

Three existing chillers were replaced and three new 800-ton chillers were added including associated chilled water and condenser pumps, and new underground utilities. The chillers, chiller pumps, and air handling units all have VFD control, which allows for modulated energy usage based on load resulting in an energy efficient cooling system.
