On-site power generation for data centers
PacinfraX energizes AI data centers with on-site natural gas generation, battery storage and a bridge to the grid. Your halls run on power built next to them, so capacity does not depend on the interconnection queue, and the utility connection follows when it is ready.

Who it's for
Who needs on-site power
Any AI deployment that cannot wait years for a grid connection benefits from power built on the campus. On-site generation gives you a date set by the campus schedule, not the utility's and a supply that the campus team operates for you.
-
Hyperscalers and AI labs
Training campuses where the date power arrives sets the date the cluster starts.
-
Neoclouds and GPU providers
New capacity that has to be sold before demand moves on.
-
Enterprises
Dedicated AI capacity with firm, on-site power.

The problem
Why the interconnection queue sets the schedule
A grid interconnection request passes through studies, upgrades and construction by the utility. The sequence belongs to the utility, so your date depends on its work. On-site power changes who controls the sequence: generation, storage and halls are built on one site by one team.
How the two paths compare
The diagram compares the two paths. On the queue path the data hall waits for the grid. On the on-site path the hall energizes from local generation, and the grid arrives later as a second source.

The model
Three layers: generation, storage and the grid bridge
Our power model has three layers that work together. Generation supplies the energy. Storage handles the fast changes. The grid connection arrives as a bridge and later as a second source.
-
On-site generation
Natural gas reciprocating engines or turbines supply continuous power to the campus.
-
Battery storage
Batteries give ride-through, peak support and smoothing of fast AI load swings.
-
Bridge to grid
The utility interconnection is added later and joins the same switchgear.

How we deliver
From load definition to bridge in six steps

Next
Define the load
We size generation and storage to your megawatts, your ramp and your redundancy target.

Plan fuel and site
Gas supply, plant location, water and heat paths are set with the campus layout.

Permit and procure
Air and construction permits are prepared while long-lead equipment is ordered.

Build the plant with the halls
Engines or turbines, switchgear and storage are built beside the data halls.

Energize and commission
Generation, storage and halls are tested together, then the first block is energized.

Bridge to the grid
The utility connection is added later without changing the supply your halls see.
Generation
Natural gas generation next to the halls
Natural gas engines and turbines are mature, widely supported machines with established fuel supply, maintenance and permitting practice. We select the prime mover for the campus: fast-start reciprocating engines suit modular growth, while turbines suit larger blocks.
Redundant units and servicing
Generation is arranged in redundant units, so one machine can be serviced while the others carry the load. Heat from the plant is a design input for the campus, and the switchgear sits between the plant and the halls.

Storage
Batteries for ride-through and fast load changes
AI training loads swing quickly as thousands of GPUs start and stop together. Battery storage absorbs those swings, carries the halls through short disturbances and lets the generators run smoothly. Storage also supports peak demand, so the plant is sized for steady load rather than every spike.

Design basis
Design basis for campus power
Campus power design values
| Element | Design intent |
|---|---|
| Prime movers | Natural gas reciprocating engines or turbines in redundant units, sized to the campus block plan. |
| Fuel | Pipeline gas supply with metering and a valve station at the campus boundary. |
| Storage | Battery energy storage for ride-through, peak support and smoothing. |
| Switchgear | Medium-voltage switchgear with transfer between generation, storage and the grid. |
| Redundancy | N+X set per hall and agreed at basis of design. |
| Controls | Campus control room with single-line diagrams, alarms and dispatch of generation and storage. |
| Grid | Interconnection added as a bridge that joins the same switchgear. |

Bridge to grid
The grid arrives later and changes nothing for you
The interconnection path continues in parallel. When the utility connection is ready, it joins the switchgear as another source. Your halls keep the same supply, and the campus gains a second path for resilience and for balancing cost.

Operations
One control room for the power plant
Operators watch generation, storage and switchgear from one control room. Single-line diagrams show every source and breaker, and alarms route to the right team. You see the same signals for your halls.

Permitting and safety
Permits, emissions and safety are part of the plan
A power plant on a data center campus needs air permits, construction permits and a fuel supply agreement. We start that work with site selection, because the permitting path shapes where the plant sits and how it is arranged. Emission controls, stack design and monitoring follow the rules that apply to the site.
Safety design for gas equipment
Safety is designed in, too. Gas equipment sits in its own zone with detection and shutdown, batteries sit in separated enclosures with monitoring, and the control room can isolate each source independently.
Permitting and safety measures
- Air permitting prepared with the site and plant layout.
- Gas detection, venting and emergency shutdown for the plant zone.
- Separation distances and fire protection for battery enclosures.
- Noise and exhaust design for neighbors and the campus itself.

On-site power generation questions
What is on-site power generation for a data center?
It is a power plant built beside the data halls, so the campus runs on its own supply instead of waiting for a grid connection.
Why does on-site power speed up energization?
The interconnection queue sets the utility's schedule. On-site generation puts the schedule in the hands of the campus team, so halls energize when the plant and halls are commissioned.
What fuel do you use?
Natural gas, delivered by pipeline to the campus. Engines and turbines are proven machines with established supply and service.
What does battery storage do for AI loads?
It provides ride-through, supports peak demand and smooths the fast swings of GPU workloads so the generators can run steadily.
4 more questions
What happens when the grid connection arrives?
It joins the same switchgear as another source. Your halls see the same supply, and the campus gains a second path.
How much redundancy do I get?
Redundancy is set per hall, usually as N+X, and agreed with your engineers at basis of design.
Where is on-site power available?
South ERCOT, Texas, with on-site gas generation and storage planned for the AI campus in development; Minnesota, powered industrial site; and Vietnam.
Can I buy power without a building?
No. PacinfraX supplies power as part of data center capacity on its campuses.
