Data Center Power Design & Critical Power Engineering

Designed from the critical load

Every design starts with the load: rack counts, power density, cooling, and a realistic growth plan. We size the utility service, generation, UPS, and distribution from that plan and phase the build so capacity arrives when the load does. Right-sized equipment runs in its efficient range and leaves room to grow without stranding floor space or capital.

Redundancy across the whole power path

A redundant UPS plant still depends on everything upstream and downstream of it. We trace each path from the utility to the server power supply, remove single points of failure, and match the architecture to your availability and maintenance requirements, from an N+1 server room to a concurrently maintainable facility with separate A and B distribution.

Server rooms, edge sites, and purpose-built facilities

We work on enterprise data centers, colocation fit-outs, on-premises server rooms, and edge computing sites at industrial and field locations. Smaller rooms often carry business-critical load with limited protection. Our assessments identify the gaps, such as a missing maintenance bypass or overloaded A and B circuits, and lay out upgrades in order of risk.

Power for high-density and AI racks

GPU servers and liquid-cooled racks draw several times the power of traditional IT equipment. We evaluate existing capacity, plan higher-voltage distribution and busway where it fits, and coordinate the electrical design with the cooling changes high-density racks require.

Studies, documentation, and commissioning

Designs include one-line diagrams, the supporting short-circuit, coordination, and arc flash studies, and the documentation operators rely on. Before a system carries load, we support commissioning against defined acceptance criteria through integrated systems testing, the same discipline we apply on aerospace mission facilities.

Based on the Central Coast

GTech is headquartered in Santa Maria and supports data center and critical power projects across San Luis Obispo and Santa Barbara Counties and throughout California. We coordinate with utilities, contractors, mechanical engineers, and equipment vendors so the design holds together from procurement through startup.

Frequently asked questions

What does data center power design include?

It covers the full electrical path that serves IT equipment: utility service, standby generators and transfer equipment, UPS systems, distribution to the rack, grounding, and monitoring, along with the studies and commissioning that verify the design. The redundancy level you choose shapes each of those systems.

What is the difference between N+1 and 2N redundancy?

N+1 adds one spare unit beyond what the load requires, so a single UPS module or generator can fail or be serviced without affecting the load. 2N provides two complete, independent power paths, each able to carry the full load, so an entire path can be lost or shut down for maintenance.

Can you upgrade power in an existing server room?

Yes. We start with an assessment of the service, UPS, circuits, loading, and cooling, then recommend upgrades in order of risk reduction, such as adding a maintenance bypass, separating A and B feeds, adding a generator connection, or increasing capacity for new equipment.

Can you plan power for GPU and AI servers?

Yes. High-density servers can exceed the capacity of existing circuits, UPS systems, and cooling. We determine what the room supports today and design the changes needed to add high-density racks safely.

Do you work with our utility, contractors, and equipment vendors?

Yes. Data center power projects involve the utility, electrical contractors, mechanical engineers, equipment manufacturers, and the building owner. We coordinate with each of them and document design decisions so the system is built and commissioned as designed.
