Who We Are
Onsite Power Generation for Data Centers and Utilities
Chateau Generation designs and deploys onsite power generation for data centers and utilities when grid capacity cannot support required load demand.
We help organizations implement onsite generation and behind-the-meter power strategies when grid capacity or infrastructure timelines delay access to electricity.
Electricity demand from AI infrastructure and hyperscale data centers is growing faster than grid capacity in many regions. As a result, the limiting factor for many new facilities is no longer compute capacity, it is access to power.
Because of this shift, onsite power generation is being increasingly evaluated by data center developers and utilities as a practical way to address power availability challenges while long-term grid infrastructure is developed.

Mission Critical Infrastructure
The Market Reality
Causing the Data Center Power Challenge
Electricity demand from data centers is rising rapidly due to artificial intelligence (AI) workloads and hyperscale cloud infrastructure.
-
Surging AI & Hyperscale Demand:
Data centers consumed ~183 TWh of electricity in 2024, representing 4% of total U.S. electricity demand, with massive growth projected through 2030 as AI computing expands.
-
The Power Bottleneck:
Access to electricity, not compute capacity, is now the limiting factor. Grid capacity cannot keep pace, pushing lead times for critical medium-voltage equipment past two years>.
-
Severe Supply Chain Delays:
Multi-year grid interconnection queues and critical equipment shortages are stalling projects, with lead times for essential medium-voltage equipment now stretching well beyond two years.
These conditions are forcing data center developers and utilities to explore alternative power strategies, including onsite generation and hybrid power architectures.

Frequently Asked Questions
Onsite power generation (or behind-the-meter power) refers to electricity generation located at or near a facility that supplies power directly to that facility rather than relying entirely on the utility grid.
Rapid growth in AI and hyperscale computing is increasing electricity demand faster than electrical infrastructure can be expanded. At the same time, supply chain constraints for transformers and other equipment are extending project timelines.
In many cases, onsite generation acts as a bridge solution until grid infrastructure becomes available. Some facilities operate with hybrid architectures that combine grid power, onsite generation, and energy storage, while others rely entirely on onsite power generation depending on location, power availability, and operational requirements.
Deployment timelines vary depending on the type of generation technology, project scale, and infrastructure requirements. While onsite generation can help accelerate access to power in some cases, projects still require program management across engineering, medium voltage equipment procurement, sequencing, and commissioning. Many developers evaluate onsite generation when grid interconnection timelines extend beyond their project schedules.
Onsite generation systems can be designed to support a wide range of electrical loads, from smaller distributed systems to large-scale generation supporting high-load facilities such as hyperscale data centers or industrial operations. System design typically depends on factors such as:
- facility load requirements
- operational redundancy needs
- long-term grid integration plans
Onsite generation can operate in several configurations:
- Full onsite generation (self-islanding mode) that supplies power directly to a facility
- Hybrid generation architectures that combine onsite generation with grid power
- Microgrid systems that coordinate multiple power sources and energy storage
Utilities and developers often work together to determine how onsite generation aligns with long-term grid infrastructure planning.
Deploying onsite generation requires more than the generation equipment itself. Projects typically involve supporting electrical infrastructure such as:
- medium-voltage distribution systems
- transformers
- switchgear
- interconnection equipment
- control systems
Coordination between generation systems and electrical infrastructure is critical to ensure reliable operation.
