SULPHUR SPRINGS, TEXAS

The project will be powered by new onsite natural gas generation that CyrusOne expects will be owned, operated and built by a leading US power company.

At startup, the data center campus is expected to be powered by onsite natural gas generation. Over time, the campus is expected to interconnect with nearby transmission infrastructure as part of its long-term power strategy.

Over time, the campus is expected to connect to transmission infrastructure located near the site. Any project-related transmission interconnection, substations, or power delivery upgrades required to serve the campus will be funded by CyrusOne, not by local taxpayers, residents, or utility customers. Based on the current project design, CyrusOne does not expect the campus to increase local electric rates. During initial operations, the campus is expected to generate its own power onsite, and any infrastructure needed to serve the project would be funded by CyrusOne rather than the local community.

Regional grid operators (ERCOT) and Transmission Service Providers (TSP) evaluate large energy projects through a detailed review process before service is approved to help ensure grid reliability is maintained. Data centers like this are required to meet similar reliability and infrastructure standards as other large industrial users.

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 applicable state 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 systems
• Site development reviewed through local planning, zoning, stormwater, and building permitting processes

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

CyrusOne's closed-loop cooling technology is designed to minimize water consumption. Unlike some cooling systems, it continuously circulates water within a sealed system inside the building to remove heat. After the initial fill, the water is reused rather than continuously consumed, meaning the cooling system does not require ongoing water use for cooling or routine wastewater discharge to the environment.

Daily water use at the campus will primarily support restrooms, basic facility operations, and limited humidification inside the buildings. Based on the current design, each building is expected to use approximately 1,250 gallons of water per day on average.

For comparison, a typical 50,000-square-foot grocery store uses approximately 3,000 gallons of water per day, based on U.S. Energy Information Administration commercial building water-use benchmarks.

No. CyrusOne uses closed-loop cooling technology designed to use very little water. This approach has been standard across our facilities for more than 15 years, reflecting our focus on using water responsibly.

Day-to-day water use at the campus will be limited to employee and visitor needs such as restrooms, breakrooms and basic cleaning.

The initial water needed to fill the cooling system would be delivered to the site rather than drawn from local supply. Because the system operates as a sealed loop, it does not require continuous water use for cooling.

Sound levels will meet applicable state and local requirements. From the start, the facility is designed to help reduce noise at the property line, with input from acoustic specialists who evaluate expected sound levels 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

This is not a heavy industrial facility, and we use no uplighting — all lighting is directed downward toward the ground. Our design minimizes light pollution to preserve dark skies.

Light mitigation measures include:

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

Yes. As the project moves through the planning process, CyrusOne intends to participate in community meetings and other public engagement opportunities to answer questions, provide project updates, and hear directly from residents. Information about future meetings will be shared as plans are finalized.

We are committed to transparency and to keeping the community informed. We will share updates on any future meetings.
