On-site power generation for AI data centers
On-site power generation puts a natural gas power plant next to your data halls. Reciprocating engines or turbines supply continuous power to the campus in redundant units, and PacinfraX builds the plant, the fuel connection and the switchgear with the halls, so your capacity energizes on a date set by the campus schedule.

Who it's for
Who benefits from on-site generation
On-site generation is for customers whose schedule depends on power. If your cluster is ready before the grid is, a plant on the campus turns a waiting period into an operating one.
-
AI labs and hyperscalers
Power for training clusters, delivered to the same date as the hall.
-
Neoclouds and GPU providers
Energized capacity sooner, with redundancy that matches the service you sell.
-
Enterprises
Dedicated AI capacity with firm, on-site power.

What you get
What on-site generation delivers
Six things on-site generation delivers
-
A date set by the campus schedule
The plant is built with the halls on one schedule, so energization follows your campus program, not a utility study.
-
Redundant units
Several machines share the load, so one can be serviced while the others run.
-
Modular growth
Units are added block by block as your campus grows from 10 MW toward 50 MW and beyond.
-
Fuel you can plan
Pipeline natural gas with a metering station at the campus boundary.
-
Heat as a design input
Exhaust and jacket heat are planned from the start, so they feed cooling or are rejected cleanly.
-
One accountable team
Plant, switchgear and halls share a single schedule and a single point of contact.
Topology
How the plant connects: gas, engines, switchgear and heat
Natural gas arrives by pipeline at a valve and metering station. Engines or turbines convert it to electricity, switchgear combines the units and routes power to the halls, and heat recovery equipment captures useful heat where the design calls for it.
The storage layer that steadies this plant is covered on battery storage.

Next
Size the plant
We turn your megawatts, ramp and redundancy target into a unit count and block plan.
-
Next
Secure the fuel
Pipeline gas supply, metering and a valve station are planned and lined up for the campus.
-
Next
Permit the plant
Air, construction and safety permits are prepared alongside the site layout.

Next
Build and connect
Engines or turbines, switchgear and controls are installed beside the halls.
-
Next
Commission under load
Units are tested alone and together, then with storage and the halls.

Operate and maintain
A campus team runs the plant, with a maintenance program planned from day one.
Engines or turbines
Reciprocating engines or gas turbines
Both machines are standard in power generation, and each has strengths. We choose per campus, and a campus can use both.
Reciprocating engines compared with gas turbines
| Consideration | Reciprocating engines | Gas turbines |
|---|---|---|
| Unit size | Smaller units, added in many steps | Larger units, added in fewer steps |
| Growth pattern | Fits modular, block-by-block campuses | Fits large single blocks |
| Part-load behavior | Efficient across a wide load range | Most efficient near full load |
| Redundancy | Many units make N+X easy | Fewer, larger units need careful arrangement |
| Heat recovery | Jacket water and exhaust heat available | High-temperature exhaust heat available |

Fuel supply
Fuel supply and the valve station
A reliable plant starts with reliable fuel. We plan the pipeline connection, pressure regulation and metering as part of the campus design. A valve station at the boundary lets operators isolate the plant, and gas detection covers the plant zone.
The South ERCOT campus plan
The South ERCOT campus in development is planned around on-site generation and storage. Each campus gets its own fuel plan, agreed with the supplier before construction.

Design basis
Design basis for the generation plant
Design basis for on-site generation
| Element | Design intent |
|---|---|
| Redundancy | N+X unit arrangement agreed per hall, with maintenance without loss of load. |
| Emissions | Controls and monitoring designed to the permit for each site. |
| Heat | Heat recovery or clean rejection planned into the cooling concept. |
| Noise | Enclosures and siting set for neighbors and campus staff. |
| Controls | Plant controls integrated with the campus control room and the storage system. |
| Maintenance | Planned service intervals and spares held for the machine type. |
Emissions permitting varies by site and fuel. We prepare the permit with the plant layout and agree conditions with the regulator before construction.

Reliability
Reliability comes from the arrangement, not one machine
A single large machine is a single point of failure. We arrange the plant as several units behind switchgear that can isolate any one of them, so a fault or a service visit removes a slice of capacity and leaves the rest of the campus running.
Storage covers the seconds when a unit trips
Storage sits beside the plant to cover the seconds when a unit trips or load steps up, and the grid bridge adds a second source later. Together the three layers give each hall a supply path that is built for the redundancy level you chose.
Four reliability arrangements
- Several units share the load, so any one can be isolated.
- Switchgear is designed to transfer between sources without interrupting the halls.
- Storage covers short disturbances while units pick up load.
- A maintenance calendar schedules service unit by unit.

FAQ
On-site power generation questions
What is on-site power generation?
It is a power plant built on the data center campus, so the halls run on their own supply instead of waiting for the grid.
What fuel does the plant use?
Natural gas delivered by pipeline, metered and regulated at a valve station on the campus boundary.
Engines or turbines?
Both are standard technology. Engines suit modular growth and part-load efficiency; turbines suit larger single blocks. We select per campus.
How is redundancy handled?
The plant is arranged in several units, usually N+X, so one machine can be serviced while others carry the load.
4 more questions
What about emissions?
Each plant is designed to the air permit for its site, with emission controls and monitoring included in the design.
Can the plant reuse heat?
Yes. Heat recovery can feed the cooling concept where the design calls for it; otherwise heat is rejected cleanly.
What happens when the grid arrives?
The grid joins the switchgear as another source. Read about bridge to grid on our power infrastructure pages.
Where is the plant available?
South ERCOT, Texas is planned around on-site generation and storage; Minnesota, powered industrial site; and Vietnam.
