Whether you’re building a new facility, expanding production capacity, or modernizing your existing plant, one of the most complex portions of the project is bringing together the electrical distribution, automation, and control systems that support operations.
Traditionally, much of that work is coordinated and integrated in the field, requiring multiple suppliers, contractors and engineering disciplines to align at exactly the right time. Integrated modular Power Distribution Centers (PDCs) offer a different way to accomplish this. Rather than engineering, fabricating and integrating critical power and control systems on the jobsite, much of that work is completed, validated, and tested before the building reaches the site.
Key Takeaways:
- Integrated Modular PDCs shift power and controls integration from the field into a controlled manufacturing environment.
- Engineering, building construction, control panel fabrication, and Factory Acceptance Testing are completed before delivery.
- Off-site execution reduces coordination challenges, field rework, and change order exposure.
- Parallel off-site fabrication shortens project schedules while improving predictability.
- Tri Tech Automation delivers the complete power and controls environment, from engineering through startup support.
Why On-Site Power and Controls Integration Creates Project Risk
In a traditional on-site project, responsibility for the power and controls environment is divided among multiple suppliers, contractors and engineering teams. One organization may supply the building, another the electrical equipment, and yet another the control panels, all while field contractors are responsible for installation and integration.
Each handoff introduces another opportunity for design conflicts, schedule delays, or scope gaps. While each supplier may successfully deliver its portion of the work, the responsibility for making everything function together often shifts to the field, where changes are expensive and schedules are under greater pressure.
For owners and EPCs, managing that coordination can become just as challenging as designing the electrical and automation systems themselves. Here’s how integrated modular PDCs change that execution model.
Moving Power and Controls Integration Off the Jobsite
An integrated modular PDC changes when and where the building and its critical electrical and automation systems come together.
Rather than coordinating those disciplines during field installation, the building and critical infrastructure inside it are engineered, assembled, and validated as a single system before delivery to the project site.
Field teams can then focus on installation and commissioning instead of resolving integration issues that are more efficiently addressed during fabrication.
How an Integrated Modular PDC Improves Project Delivery
Integrated modular PDCs help reduce project risk in several ways:
- Engineering issues are resolved earlier. Designing the building, electrical distribution and control systems together reduces design conflicts and minimizes field modifications.
- More testing happens before the project reaches the site. Factory Acceptance Testing validates the integrated system in a controlled environment, allowing issues to be addressed before installation and commissioning begin.
- Construction and fabrication happen at the same time. While foundations and site work continue, the PDC is engineered, fabricated and tested off-site, helping compress the overall project schedule.
- Less work moves to the field. Completing more of the work in a manufacturing environment reduces dependence on field labor while minimizing weather delays and jobsite congestion.
- Fewer change orders are required. By resolving engineering and integration issues before equipment reaches the jobsite, integrated modular PDCs help minimize field modifications that often trigger costly change orders.
Where an Integrated PDC Delivers the Greatest Value
While integrated modular PDCs can support a wide range of industrial projects, they provide the greatest value where electrical infrastructure is complex, schedules are compressed, and startup certainty is critical.
Oil & Gas
Whether supporting upstream, midstream, or downstream operations, oil and gas projects often involve complex electrical and automation systems, remote locations, and aggressive construction schedules with hefty costs associated with project delays. An integrated PDC helps simplify execution while reducing field coordination.
Power Generation & Utilities
Power generation projects demand reliable electrical infrastructure and predictable commissioning. Complete engineering, fabrication, and Factory Acceptance Testing before delivery helps improve installation efficiency and startup readiness.
Chemical & Process Manufacturing
Chemical facilities rely on tightly integrated electrical and control systems operating in demanding environments. Delivering those systems as a fully integrated solution helps reduce project complexity while supporting safe, efficient startup.
Mining & Metals
Mining projects frequently face remote jobsites, limited labor availability, and challenging environmental conditions. Modular PDCs reduce the amount of work required in the field while helping maintain project schedules.

Modular PDCs: Frequently Asked Questions
What is a modular Power Distribution Center (PDC)?
A modular Power Distribution Center (PDC) is a prefabricated building that houses the electrical distribution, control systems, and supporting infrastructure required to power and operate an industrial facility. Rather than assembling these systems entirely in the field, they are engineered, installed, and tested in a controlled manufacturing environment before being delivered to the project site. This approach helps simplify installation, improve quality, and reduce the coordination challenges often associated with traditional field-built electrical infrastructure.
When does an integrated modular PDC make sense?
An integrated modular PDC is particularly well suited for projects with complex electrical and automation requirements, compressed construction schedules, or limited field labor availability. It is commonly used for new facilities, plant expansions, brownfield modernization projects, and remote installations where minimizing on-site work can improve project efficiency. By completing more engineering, fabrication, and testing before delivery, integrated modular PDCs help owners and EPCs reduce project complexity while supporting a more predictable path to startup.
What are the advantages of an integrated modular PDC versus traditional field-built construction?
An integrated modular PDC shifts much of the engineering, fabrication, and testing from the jobsite to a controlled manufacturing environment. This allows electrical distribution, control systems, and the modular building itself to be designed and validated as a single solution before delivery. The result is fewer field modifications, reduced coordination between multiple suppliers, improved quality, greater schedule predictability, and a more efficient commissioning process. While every project is unique, many organizations use modular PDCs to reduce execution risk and accelerate project delivery.
How early should a PDC provider be involved in a capital project?
The greatest benefits are realized when a modular PDC provider is engaged during the early planning and engineering phases of a project. Early involvement allows the building, electrical distribution, control systems, and supporting infrastructure to be designed as an integrated solution rather than coordinated later in construction. This approach helps identify potential issues before fabrication begins, reduces late-stage design changes, and creates a more efficient path from engineering through installation and commissioning.
What happens during Factory Acceptance Testing of a PDC?
Factory Acceptance Testing (FAT) verifies that the integrated electrical and control systems perform as intended before the modular PDC is shipped to the project site. During FAT, equipment, control panels, and system functionality are tested in a controlled environment using project-specific acceptance criteria. Identifying and resolving issues before delivery helps reduce commissioning challenges, minimizes field troubleshooting, and provides owners and EPCs with greater confidence before installation begins.
Can a modular PDC be customized for my project?
Yes. Modular PDCs are engineered to meet the specific electrical, automation, and operational requirements of each project. Depending on the application, they can be configured to accommodate switchgear, motor control centers, variable frequency drives, PLC systems, networking equipment, HVAC systems, fire protection, and other supporting infrastructure. The building itself is also designed to meet the project’s environmental, structural, and regulatory requirements, creating a solution tailored to the facility’s unique operating conditions.
Which industries benefit most from modular PDCs?
Integrated modular PDCs are widely used in industries where electrical infrastructure is complex, and project execution is critical. Common applications include oil and gas, power generation, chemical processing, mining and metals, water and wastewater, and other industrial manufacturing environments. These industries often operate under demanding schedules, remote site conditions, or complex commissioning requirements, making an integrated, off-site approach particularly valuable for improving project efficiency and startup readiness.
Why choose an integrated PDC provider instead of managing multiple vendors?
An integrated provider assumes responsibility for coordinating the engineering, electrical systems, control panels, modular building, and Factory Acceptance Testing as a single solution. Rather than managing multiple suppliers and resolving coordination issues during construction, owners and EPCs receive a more complete, fully integrated deliverable. This approach helps reduce communication gaps, simplify project management, and minimize the field modifications that can lead to schedule delays and change orders.
How can a modular PDC protect electrical equipment from water intrusion and harsh environments?
Protecting critical electrical and automation equipment begins with the design of the modular building itself. A well-engineered PDC should minimize opportunities for water intrusion while providing long-term structural durability in demanding industrial environments. Features such as precision roll-formed wall and roof panels, interlocking wall systems, hidden exterior fasteners, and corrosion-resistant materials help reduce potential leak paths and protect the equipment inside throughout the life of the facilities. Tri Tech incorporates these design principles into every modular PDC, helping owners protect critical electrical infrastructure while reducing long-term maintenance concerns.
