Yorkville Technology Campus

Once fully operational, the campus will employ a minimum of 100 permanent, full-time employees over time, supporting technical operations, facility management, and other essential support roles.

Staffing levels will scale as individual buildings are constructed and brought online, with positions drawing from a broad range of experience and skillsets, many of which do not require a college degree.

This project represents a capital investment exceeding $1 billion across multiple phases. The facility will generate ongoing property tax revenue that directly funds schools, fire departments, emergency services, and essential local services.

At full buildout, the property is expected to generate approximately $15 million annually for the tax districts that serve the site.

No. CyrusOne is not requesting a property tax abatement for this project.

Property tax assessments and payments are administered by the appropriate local authorities in accordance with Illinois law. CyrusOne will comply with all applicable tax regulations.

Tax revenue is only one component of the total economic impact. This 24/7 operation will increase demand for support services throughout the region, support hiring in local companies outside of CyrusOne, and provide hundreds of construction jobs throughout the development lifecycle.

The campus is to be served through dedicated transmission infrastructure designed specifically for the facility and funded by CyrusOne. This infrastructure is will support the project’s power needs without relying on existing neighborhood distribution systems that serve homes and local businesses.

All project-related transmission interconnection and power delivery costs are paid directly by CyrusOne, not local taxpayers or residents.

ComEd and regional grid operators evaluate large energy users through a detailed review process before service is approved to help ensure grid reliability is maintained. Data centers like this are required to meet the same reliability and infrastructure standards as other large industrial users.

CyrusOne uses closed-loop cooling technology designed to minimize water consumption. Water usage at the campus will primarily support restrooms, breakrooms, basic facility operations, and limited humidification.

Each building is expected to use approximately 1,200 gallons of water per day on average. For comparison, a typical grocery store can use between 2,000 and 5,000 gallons of water daily.

A closed-loop cooling system continuously circulates water within a sealed system inside the building to remove heat.   Because the system remains closed after the initial fill, there is no ongoing wastewater discharge associated with the cooling process and no routine release to surrounding soil or groundwater. 

No. CyrusOne uses closed-loop cooling technology designed to minimize water consumption. Closed-loop cooling has been the standard across CyrusOne facilities for more than a decade because we recognize water is a valuable resource and design our campuses to use it responsibly.

Water use at the campus will primarily support restrooms, basic facility operations, and limited humidification.

Because the cooling system operates as a sealed, closed-loop system, there is no ongoing discharge from the cooling process during normal operations. 

No. The campus uses a sealed, closed-loop cooling system designed with no ongoing discharge from the cooling process during normal operations.

The cooling system is self-contained and does not discharge to soil or groundwater. Any system maintenance involving fluids is handled by licensed contractors in accordance with applicable environmental regulations.

Non-cooling wastewater from restrooms and basic facility operations will be managed through code-compliant septic systems designed to protect soil and groundwater quality.

Sound levels will meet Illinois Pollution Control Board noise standards and applicable local requirements.

CyrusOne facilities are designed with sound mitigation measures incorporated into the site and building design. The project team includes acoustic consultants who evaluate expected sound levels at property boundaries before construction begins.

Sound mitigation measures include:

• Sound-attenuated cooling equipment
• Sound-attenuated emergency backup generator enclosures
• Critical-grade exhaust silencers on emergency backup generators
• Strategic setbacks from property lines
• Acoustic barriers around chiller and generator equipment

Light mitigation measures include:

• Exterior lighting directed downward
• No uplighting
• Shielded fixtures to prevent light spill
• Design intended to minimize light pollution and preserve dark skies

Backup generators include modern emissions controls and are subject to EPA and State of Illinois air quality regulations.

Generators are used infrequently — primarily for required maintenance testing and during emergency power interruptions. Testing and operation are regulated under applicable environmental permits and emissions standards.

Data centers are subject to applicable federal, state, and local environmental, building, fire safety, and operational regulations.

Key areas of oversight for this project include:

• Backup generators regulated under EPA and Illinois air quality standards
• Closed-loop cooling systems designed to minimize water use and avoid ongoing cooling discharge during normal operations
• Sanitary wastewater from restrooms and sinks handled through code-compliant septic systems
• Site development reviewed through local planning, zoning, stormwater, and building permitting processes

Operations must comply with applicable environmental regulations, including EPA standards, Illinois EPA requirements, and local ordinances.
